The owners of private houses are trying in every possible way to save on heating, which requires considerable costs from year to year. In order to create heating economical systems in residential, industrial, public spaces developed and put into practice various schemes to generate profitable thermal energy. For these purposes, a cavitation heat generator is suitable.

To save on thermal energy - this heat generator will help you with this

Vortex device: general concept

Such an installation is structurally quite simple. It is used for efficient and profitable heating of a building with minimal financial outlay. Profitability is caused by special heating of water through cavitation. This method consists in creating small bubbles from steam in the zone of reduced pressure of the working fluid, which is provided by special sound vibrations, the operation of the pump.

The cavitation heater copes with the processing of mechanical energy into a heat flow, which is important for industrial facilities. In them heating elements periodically fail, because they operate with liquids of a large difference in temperature.

It is these cavitators that are a reliable replacement for devices whose operation depends on solid fuels.

In this video you will learn how the heat generator works:

Cavitation generators: advantages

Such settings have been found wide application in quarry conditions and in production. The reason for this is the following factors that characterize them:

• affordability;
• efficiency of the heating system;
• the possibility of creating a structure with your own hands;
• high heating efficiency.

The operating rules state that it is impossible to install vortex products inside the living space due to the creation of high-level noise. The best option will be the arrangement of a separate outbuilding, a boiler room.

The disadvantages are quite big sizes heater ready for use. Also noted is excessive power for a private house, cottage, the possible difficulty in acquiring materials that will be needed in the case of self-manufacturing of the cavitator.

In this heater, one of the advantages is high efficiency

The structure of the heater and the principle of operation

Cavitation heating is characterized by the formation of bubbles from steam in the working fluid. As a result of this action, the pressure is gradually reduced due to the high flow rate. It should be noted that the necessary vaporization is set by special radiation of laser pulses or by acoustics set by certain sounds. Air areas closed type They mix with the water mass, after which they enter the zone of high pressure, where they open up and emit the expected shock wave.

Cavitation type equipment differs in the way it functions. Schematically, it looks like this:

1. The water flow moves through the cavitator, in which, with the help of a circulation pump, operating pressure entering the working tank.
2. Further, in such containers, the speed increases, respectively, and the pressure of the liquid through the tubes installed according to the drawings.
3. The flows, reaching the central part of the chamber, are mixed, as a result of which cavitation is formed.
4. As a result of the described process, the vapor bubbles do not increase in size, and there is no interaction between them and the electrodes.
5. After that, the water moves to the opposite part of the tank and returns to complete a new circle.
6. Heating is provided by the movement and expansion of the liquid at the point of exit from the nozzle.

It can be seen from the work of the vortex installation that its design is uncomplicated and simple, but at the same time it provides fast and profitable space heating.

Types of heaters

A cavitation heating boiler is one of the most common types of heaters. The most requested of them:

1. Rotary installations, among which special attention deserves the Griggs device. The essence of its action is based on a centrifugal rotary pump. Outwardly, the described design resembles a disk with several holes. Each such niche is called a Griggs cell, their number and functional parameters are interdependent with the speed of the drive, the type of generator set. The working fluid is heated in the space between the rotor and the stator due to the rapid movement along the disk surface.
2. Static heaters. The boilers are devoid of any moving parts, cavitation in them is provided by special Laval elements. Installed in heating system the pump sets the required water pressure, which begins to move quickly and heat up. Due to the narrow holes in the nozzles, the liquid moves in an accelerated mode. Due to its rapid expansion, the necessary cavitation for heating is achieved.

The choice of one or another heater depends on the needs of the person. It should be borne in mind that the rotary cavitator is more productive, besides, it is smaller.

The peculiarity of the static unit is the absence of rotating parts, which determines its long service life. Duration of work without Maintenance reaches 5 years. If the nozzle breaks, it can be easily replaced, which is much cheaper compared to acquiring a new working element in a rotary installation.

Independent production of equipment

Creating a cavitator with your own hands is quite realistic, but first you should familiarize yourself with the schematic features, accurate drawings of the unit, understand and study in detail the principle by which it operates. The simplest model is considered to be the Potapov VTG with an efficiency of 93%. Schematically, the heat generator is quite simple., will be appropriate in everyday life and industrial use.

Starting to assemble the unit, it is necessary to select a pump in the system, which must fully meet the requirements of the power required by the thermal energy. For the most part, the described generators are shaped like a nozzle; such models are the most convenient and simple to use. home use.

When creating a heat generator with our own hands, we do not forget the necessary spare parts, for example, sleeves

Creating a cavitator is impossible without pre-training certain tools and devices. These include:

• branch pipes of inlet and outlet type, equipped with taps;
• pressure gauges;
• thermometer, without which it is impossible to measure the temperature;
• sleeves with which thermometers are supplemented;
• valves, with the help of which air plugs are eliminated from the entire heating system.

The sequence of designing a cavitation heat generator with your own hands is represented by the following steps:

1. Selecting a pump that is designed to operate with liquids high temperatures. Otherwise, it will quickly fail. A mandatory requirement is imposed on such an element: the creation of pressure from 4 atmospheres.
2. Execution capacity for cavitation. The main condition is the selection of the passage channel necessary for the cross section.
3. Choice of a nozzle taking into account features of a configuration. Such a part can be cylindrical, cone-shaped, rounded. It is important that a vortex process develops at the inlet of water into the tank.
4. The preparation of the outer contour is an important procedure. It is a curved tube that extends from the cavitation chamber. Further, it is connected to two thermometer sleeves and two pressure gauges, as well as to an air valve placed in the space between the outlet and the inlet.

When the work with the case is finished, you should experiment with the heater. The procedure is to bring pumping unit to the mains, while the radiators are connected to the heating system. The next step is to turn on the network.

Should be carried out strict control indicators of manometers. The difference between the numbers at the input and output should fluctuate within 8-12 atmospheres.

If the structure is working properly, the required amount of water is supplied to it. Good indicator- heating the liquid by 3-5 degrees in 10-15 minutes.

A cavitation-type heater is a cost-effective installation, heats the building in a short time, and is also the most economical. If desired, it is easily constructed at home, which will require affordable and inexpensive fixtures.

Making a heat generator with your own hands is a rather complicated and painstaking process. Usually, this device necessary to ensure economical heating in dwellings. Heat generators come in 2 designs: static and rotary. In the first case, a nozzle must be used as the main element. In a rotary generator, an electric motor should be used to create cavitation.

This unit is a modernized centrifugal pump, or rather its casing, which will serve as a stator. You can not do without a working chamber and nozzles.

Inside the body of our hydrodynamic design is a flywheel as an impeller. There is a huge variety of rotary designs of heat generators. The simplest among them is the disk design.

On the cylindrical surface the required number of holes are applied to the rotor disk, which must have a certain diameter and depth. They are called "Griggs cells". It should be noted that the size and quantity drilled holes will vary depending on the caliber of the rotor disk and the speed of the electric motor shaft.

The body of such a heat source is most often made in the form of a hollow cylinder. Essentially, this is ordinary pipe with welded flanges at the ends. The gap between the inside of the housing and the flywheel will be very small (approximately 1.5-2 mm).

Direct heating of water will occur in this gap. The heating of the liquid is obtained due to its friction on the surface of the rotor and housing at the same time, while the flywheel disk moves almost at maximum speeds.

Cavitation (formation of bubbles) processes that occur in rotary cells have big influence for heating the liquid.

A rotary heat generator is a modernized centrifugal pump, or rather its casing, which will serve as a stator

As a rule, the diameter of the disk in this type heat generators is 300 mm, and the speed of rotation of the hydraulic device is 3200 rpm. Depending on the size of the rotor, the speed will vary.

Analyzing the design of this installation, we can conclude that its service life is quite small. Due to the constant heating and abrasive action of the water, the gap gradually expands.

It should be noted that rotary heat generators during operation create a lot of noise. However, in comparison with other hydraulic devices (static type), they are 30% more productive.

Production of Potapov's vortex heat generator

Many other devices have been developed that operate on completely different principles. For example, do-it-yourself Potapov vortex heat generators. They are called static conditionally. This is due to the fact that the hydraulic device does not have rotating parts in the design. As a rule, vortex heat generators receive heat using a pump and an electric motor.

The most important step in the process of making such a heat source with your own hands will be the choice of an engine. It should be selected depending on the voltage. There are multiple drawings and diagrams of a do-it-yourself vortex heat generator, which demonstrate methods for connecting a 380-volt electric motor to a 220-volt network.

Frame assembly and engine installation

Do-it-yourself installation of Potapov's heat source begins with the installation of an electric motor. Fix it on the bed first. Then using the angular grinder make corners. Cut them from a suitable square. After making 2-3 squares, fasten them to the crossbar. Then with the help welding machine assemble a rectangular structure.

If you don’t have a welding machine at hand, you don’t need to cut the squares. Just cut out triangles in the places of the intended fold. Then bend the squares using a vise. Use bolts, rivets and nuts to secure.

After assembly, you can paint the frame and drill holes in the frame to install the engine.

Pump installation

The next important element of our vortex hydraulic design will be a pump. Nowadays, in specialized stores, you can easily purchase a unit of any capacity. When choosing it, pay close attention to 2 things:

1. It must be centrifugal.
2. Choose a unit that will work optimally with your electric motor.

Once you have purchased the pump, mount it to the frame. If there are not enough crossbars, make 2-3 more corners. In addition, it will be necessary to find coupling. It can be carved into lathe or purchase at any hardware store.

Do-it-yourself Potapov's vortex cavitation wood-fired heat generator consists of a body, which is made in the form of a cylinder. It is worth noting that through holes and pipes must be present at its ends, otherwise you will not be able to properly connect the hydraulic structure to the heating system.

Insert the jet immediately behind the inlet pipe. It is selected individually. However, remember that its hole should be 8-10 times smaller than the diameter of the pipe. When making too small hole The pump will overheat and will not be able to properly circulate the water.

In addition, due to the formation of steam, Potapov's vortex cavitation heat generator on wood will be highly susceptible to hydroabrasive wear.

How to make a pipe

The manufacturing process of this element of Potapov's wood-fired heat source will take place in several stages:

1. First, using a grinder, cut a piece of pipe with a diameter of 100 mm. The length of the workpiece must be at least 600-650 mm.
2. Then make an external groove in the workpiece and cut the thread.
3. After that, make two rings 60 mm long. the caliber of the rings must match the diameter of the pipe.
4. Then cut the threads for the half rings.
5. Next stage- production of lids. They must be welded on the side of the rings where there is no thread.
6. Next, drill a central hole in the covers.
7. Then, using a large caliber drill, make a chamfer with inside covers.

After the performed operations, the wood-fired cavitation heat generator should be connected to the system. Insert a nozzle with a nozzle into the pump hole from where water is supplied. Connect the other fitting to the heating system. Connect the outlet from the hydraulic system to the pump.

If you want to control the temperature of the liquid, install a ball mechanism right behind the nozzle. With its help, the Potapov wood-fired heat generator will drive water around the entire device much longer.

Is it possible to improve the performance of the Potapov heat source

In this device, as in any hydraulic system, heat is lost. Therefore, it is desirable to surround the pump with a water "shirt". To do this, make a heat-insulating case. The outer caliber of such protective device make it larger than the diameter of your pump.

As a blank for thermal insulation, you can use a finished 120 mm pipe. If you do not have such an opportunity, you can make a parallelepiped with your own hands using sheet steel. The dimensions of the figure should be such that the entire structure of the generator can easily fit into it.

The workpiece must be made from quality materials to withstand without problems high pressure in system.

In order to further reduce heat loss around the body, make thermal insulation, which can later be sheathed with a casing of tin.

Absolutely any material that can withstand the boiling point of water can be used as an insulator.

The manufacture of a heat insulator will take place in several stages:

1. First, assemble the device, which will consist of a pump, a connecting pipe, a heat generator.
2. After that, select the optimal dimensions of the heat-insulating device and find a pipe of a suitable caliber.
3. Then make covers on both sides.
4. After that, securely fasten the internal mechanisms of the hydraulic system.
5. At the end, make an inlet and fix (weld or screw) a pipe into it.

After the performed operations, weld the flange at the end of the hydraulic pipe. If you have difficulty mounting internal mechanisms, you can make a frame.

Be sure to check the tightness of the heat generator components and your hydraulic system for leaks. At the end, do not forget to adjust the temperature with a ball.

Frost protection

First of all, make a casing of a heater. To do this, take a galvanized sheet or thin sheet aluminum. Cut out two rectangles. Remember that it is necessary to bend the sheet on a mandrel of a larger diameter. You can also bend the material on the crossbar.

First, lay the cut out sheet and press it on top wooden block. With the other hand, press the sheet so that a slight bend forms along the entire length. Then move your workpiece to the side a little and continue to bend it until you get a hollow cylinder.

After that, make a cover for the casing. It is advisable to wrap the entire thermal insulation structure with a special heat-resistant material (glass wool, etc.), which must subsequently be fixed with a wire.

Tools and devices

materials

1. Wire.
2. Thin sheet of aluminum.
3. Pipe with a diameter of 300 mm.
4. Lock.
5. Warming materials.
6. Galvanized sheet.

In conclusion, it is worth noting that heat generators will help you save an impressive amount of money. However, for the rational operation of the device, it is necessary to take a responsible approach to the process of manufacturing a heat insulator and sheathing.

Yu. S. Potapov's heat generator is very similar to the vortex tube of J. Ranke, invented by this French engineer back in the late 20s of the XX century. While working on the improvement of cyclones for cleaning gases from dust, he noticed that the gas jet emerging from the center of the cyclone has more low temperature than the source gas supplied to the cyclone. Already at the end of 1931, Ranke filed an application for an invented device, which he called a "vortex tube". But he manages to get a patent only in 1934, and then not in his homeland, but in America (US Patent No. 1952281.)

The French scientists then treated this invention with distrust and ridiculed the report of J. Ranke, made in 1933 at a meeting of the French Physical Society. For according to these scientists, the work of the vortex tube, in which the air supplied to it was divided into hot and cold streams as a fantastic "Maxwell's demon", contradicted the laws of thermodynamics. Nevertheless, the vortex tube worked and later found wide application in many areas of technology, mainly for obtaining cold.

We are most interested in the work of Leningrader V. E. Finko, who drew attention to a number of paradoxes of the vortex tube while developing a vortex gas cooler to obtain ultralow temperatures. He explained the process of gas heating in the near-wall region of the vortex tube by the “mechanism of wave expansion and compression of gas” and discovered the infrared radiation of gas from its axial region, which has a band spectrum, which later helped us to understand the operation of the Potapov vortex heat generator.

In the Ranke vortex tube, the diagram of which is shown in Figure 1, the cylindrical tube 1 is connected at one end to the volute 2, which ends with a nozzle inlet rectangular section, providing the supply of compressed working gas into the pipe tangentially to its circumference inner surface. At the other end, the volute is closed by a diaphragm 3 with a hole in the center, the diameter of which is significantly less than the inner diameter of pipe 1. Through this hole, a cold gas flow exits pipe 1, which is divided during its vortex movement in pipe 1 into cold (central) and hot (peripheral) parts. The hot part of the flow, adjacent to the inner surface of the pipe 1, rotates, moves to the far end of the pipe 1 and leaves it through the annular gap between its edge and the adjusting cone 4.

Figure 1. Ranke vortex tube: 1-tube; 2- snail; 3- diaphragm with a hole in the center; 4 - adjusting cone.

A complete and consistent theory of the vortex tube still does not exist, despite the simplicity of this device. “On the fingers” it turns out that when the gas is untwisted in a vortex tube, it is compressed near the tube walls under the action of centrifugal forces, as a result of which it heats up here, as it heats up when compressed in a pump. And in the axial zone of the pipe, on the contrary, the gas experiences rarefaction, and then it cools, expanding. By removing the gas from the near-wall zone through one hole, and from the axial zone through the other, the initial gas flow is separated into hot and cold flows.

Liquids, unlike gases, are practically incompressible. Therefore, for more than half a century, it never occurred to anyone to supply water to the vortex tube instead of gas or steam. And the author decided on a seemingly hopeless experiment - he fed water from the water supply into the vortex tube instead of gas.

To his surprise, the water in the vortex tube split into two streams with different temperatures. But not hot and cold, but hot and warm. For the temperature of the "cold" flow turned out to be slightly higher than the temperature of the source water supplied by the pump to the vortex tube. Careful calorimetry showed that such a device generates more thermal energy than is consumed by the electric motor of the pump that supplies water to the vortex tube.

So the Potapov heat generator was born.

Heat generator design

It is more correct to speak about the efficiency of the heat generator - the ratio of the amount of thermal energy generated by it to the amount of electrical or mechanical energy consumed by it from the outside. But at first, the researchers could not understand where and how excess heat appears in these devices. It has even been suggested that the law of conservation of energy is violated.

Figure 2. Scheme of a vortex heat generator: 1-injection pipe; 2- snail; 3- vortex tube; 4- bottom; 5- flow straightener; 6- fitting; 7- flow straightener; 8- bypass; 9 - branch pipe.

The vortex heat generator, the diagram of which is shown in Figure 2, is connected with an injection pipe 1 to the flange centrifugal pump(not shown in the figure), supplying water under pressure of 4-6 atm. Getting into the snail 2, the water flow itself twists in a vortex motion and enters the vortex tube 3, the length of which is 10 times greater than its diameter. The swirling vortex flow in pipe 3 moves along a helical spiral near the pipe walls to its opposite (hot) end, ending in bottom 4 with a hole in its center for hot flow to exit. In front of bottom 4, a braking device 5 is fixed - a flow straightener made in the form of several flat plates radially welded to a central sleeve coaxial with pipe 3. In the top view, it resembles feathered bombs or mines.

When the vortex flow in pipe 3 moves towards this straightener 5, a counterflow is generated in the axial zone of pipe 3. In it, the water, also rotating, moves to the fitting 6, cut into the flat wall of the volute 2 coaxially with the pipe 3 and designed to release the "cold" stream. In nozzle 6, the inventor installed another flow straightener 7, similar to brake device 5. It serves to partially convert the rotational energy of the "cold" flow into heat. And coming out of it warm water sent through the bypass 8 to the branch pipe 9 of the hot outlet, where it mixes with the hot stream leaving the vortex tube through the rectifier 5. From the branch pipe 9, the heated water enters either directly to the consumer or to a heat exchanger (all about), transferring heat to the consumer circuit. In the latter case, the waste water from the primary circuit (already at a lower temperature) returns to the pump, which again feeds it into the vortex tube through pipe 1.

After careful and comprehensive tests and checks of several instances of the YUSMAR heat generator, they came to the conclusion that there were no errors, the heat is actually obtained more than the mechanical energy input from the pump motor that supplies water to the heat generator and is the only consumer of energy from the outside in this device.

But it was not clear where the "extra" heat comes from. There were speculations about a hidden huge internal energy fluctuations of the "elementary oscillators" of water released in the vortex tube, and even about the release of the hypothetical energy of the physical vacuum in its non-equilibrium conditions. But these are only assumptions, not supported by specific calculations confirming the experimentally obtained figures. Only one thing was clear: a new source of energy had been discovered and it looked like it was, in fact, free energy.

In the first modifications of thermal installations, Yu. S. Potapov connected his vortex heater, shown in Figure 2, to the outlet flange of an ordinary frame centrifugal pump for pumping water. In this case, the entire structure was surrounded by air (If anything about air heating at home with their own hands) and was easily accessible for maintenance.

But the efficiency of the pump, as well as the efficiency of the electric motor, is less than one hundred percent. The product of these efficiencies is 60-70%. The rest is losses that go mainly to heat the ambient air. But the inventor sought to heat water, not air. Therefore, he decided to place the pump and its electric motor in water to be heated by a heat generator. For this, a submersible (borehole) pump was used. Now the heat from heating the motor and pump was no longer given off into the air, but to the water that needed to be heated. This is how the second generation of vortex heating plants appeared.

Potapov's heat generator converts part of its internal energy into heat, or rather part of the internal energy of its working fluid - water.

But let's get back to serial thermal installations of the second generation. In them, the vortex tube was still in the air on the side of the thermally insulated vessel, in which the downhole motor-pump was immersed. From the hot surface of the vortex tube, the surrounding air was heated, taking away part of the heat intended for heating the water. It was necessary to wrap the pipe with glass wool to reduce these losses. And in order not to deal with these losses, the pipe was immersed in the vessel in which the motor and pump are already located. This is how the last serial design of a water heating installation appeared, which received the name YUSMAR.

Figure 3. Scheme of the YUSMAR-M heat plant: 1 - vortex heat generator, 2 - electric pump, 3 - boiler, 4 - circulation pump, 5 - fan, 6 - radiators, 7 - control panel, 8 - temperature sensor.

Installation YUSMAR-M

In the YUSMAR-M unit, a vortex heat generator complete with submersible pump placed in a common vessel-boiler with water (see Figure 3) so that the heat loss from the walls of the heat generator, as well as the heat released during the operation of the pump motor, also went to heat the water, and were not lost. Automation periodically turns on and off the heat generator pump, maintaining the temperature of the water in the system (or the air temperature in the heated room) within the limits specified by the consumer. Outside, the vessel-boiler is covered with a layer of thermal insulation, which simultaneously serves as sound insulation and makes the noise of the heat generator almost inaudible even directly next to the boiler.

YUSMAR units are designed to heat water and supply it to the systems of autonomous, industrial and administrative buildings, as well as to showers, baths, kitchens, laundries, washes, for heating dryers of agricultural products, pipelines of viscous oil products to prevent them from freezing in frost and other industrial and domestic needs.

Figure 4. Photo of the YUSMAR-M thermal installation

The YUSMAR-M units are powered by an industrial three-phase 380 V network, are fully automated, are supplied to customers complete with everything necessary for their operation and are assembled by the supplier on a turnkey basis.

All these installations have the same vessel-boiler (see Figure 4), into which vortex tubes and motor-pumps of different capacities are immersed, choosing the most suitable for a particular customer. Boiler vessel dimensions: diameter 650 mm, height 2000 mm. These installations, recommended for use both in industry and in everyday life (for heating residential premises by supplying hot water in water heating batteries), there are specifications TU U 24070270.001 -96 and a certificate of conformity ROSS RU. MHOZ. C00039.

YUSMAR units are used in many enterprises and private households, they have received hundreds of accolades from users. At present already thousands of YUSMAR heating plants are successfully operating in the CIS countries and a number of other countries in Europe and Asia.

Their use is especially beneficial where gas pipelines have not yet reached and where people are forced to use electricity to heat water and space heating, which is becoming more and more expensive every year.

Figure 5. Scheme of connecting the thermal installation "YUSMAR-M" to the water heating system: 1 - heat generator "YUSMAR"; 2 - circular pump; 3-control panel; 4 - thermostat.

YUSMAR heat installations allow saving one third of the electricity that is needed for water heating and space heating traditional methods electric heating.

Two schemes for connecting consumers to the YUSMAR-M heat plant have been worked out: directly to the boiler (see Figure 5) - when the hot water consumption in the consumer's system is not subject to drastic changes(for example, for heating a building), and through a heat exchanger (see Figure 6) - when the consumer's water consumption fluctuates over time.

YUSMAR heating installations do not have parts that heat up to temperatures above 100°C, which makes these installations especially acceptable in terms of fire safety and safety technology.

The Potapov vortex heat generator, or VTP for short, was designed specifically to receive thermal energy with just an electric motor and pump. Such a device is used primarily as an economical source of heat.

Today we will consider the design features of this device, as well as how to make a vortex heat generator with our own hands.

Principle of operation

The generator works as follows. Water (or any other coolant used) enters the cavitator. The electric motor then spins the cavitator, in which the bubbles collapse - this is cavitation, hence the name of the element. So all the liquid that enters it begins to warm up.

The electricity required to run a generator is spent on three things:

• On the formation of sound vibrations.
• To overcome the force of friction in the device.
• For heating a liquid.

At the same time, according to the creators of the device, in particular, the Moldavian Potapov himself, renewable energy is used for work, although it is not entirely clear where it comes from. Be that as it may, no additional radiation is observed, therefore, we can talk about almost one hundred percent efficiency, because almost all the energy is spent on heating the coolant. But that's in theory.

What is it used for?

Let's bring small example. There are many enterprises in the country that, for one reason or another, cannot afford gas heating: or there is no highway nearby, or something else. Then what is left? Heat with electricity, but the tariffs for this kind of heating can be terrifying. This is where Potapov's miracle device comes to the rescue. When using it, the cost of electricity will remain the same, the efficiency, of course, too, since it still won’t be more than a hundred, but the financial efficiency will be from 200% to 300%.

It turns out that the efficiency of the vortex generator is 1.2-1.5.

Required Tools

Well, it's time to start self-manufacturing generator. Let's see what we need:

• Angle grinder, or impeller;
• Iron corner;
• Welding;
• Bolts, nuts;
• Electric drill;
• Keys 12-13;
• Drills for drills;
• Paint, brush and primer.

Manufacturing technology. Engine

Note! Due to the fact that there is no information regarding the characteristics of the device in terms of pump power, all parameters given below will be approximate.

The easiest option to make a vortex heat generator with your own hands is to use standard parts in your work. Almost any engine can suit us, the more power it has, the more coolant it can heat. When choosing an electric motor, you should first of all consider the voltage in your home. The next step is to create a frame for the engine. The bed is an ordinary iron frame, for which it is better to use iron corners. We will not say any dimensions, since they depend on the dimensions of the engine and are determined on the spot.

1. We cut the squares of the required length with a turbine. We weld from them a square structure of such dimensions that all the elements fit there.
2. We cut out an additional corner and weld it to the frame across so that an electric motor can be attached to it.
3. We paint the bed, wait until it dries.
4. We drill holes for fasteners, we fix the electric motor.

Installing the pump

Next, we must choose the "right" water pump. The range of these tools today is so wide that you can find a model of any strength and dimensions. We only need to pay attention to two things:

• Will the engine be able to spin this pump;
• Is it (pump) centrifugal.

At the vortex generator, the body is a cylinder, closed on both sides. On the sides there should be through holes through which the device will be connected to the heating system. But main feature construction - inside the case: a jet is located immediately near the inlet. The jet opening must be selected purely individually.

Note! At the same time, it is desirable that the jet opening be half as large as 1/4 of the total cylinder diameter. If the hole is smaller, then water will not be able to pass through it in required quantity and the pump will start to heat up. Moreover, the internal elements will begin to collapse by cavitation.

To make the case, we need the following tools:

1. An iron pipe with thick walls, about 10 cm in diameter;
2. Couplings for connection;
3. Welding;
4. Several electrodes;
5. turbine;
6. A pair of pipes in which the thread is made;
7. Electric drill;
8. Drill;
9. Adjustable wrench.

Now - directly to the manufacturing process.

1. To begin with, we cut off a piece of pipe about 50-60 cm long and make an external groove on its surface about half the thickness, 2-2.5 cm. We cut the thread.
2. We take two more pieces of the same pipe, each 5 cm long, and make a couple of rings out of them.
3. Then we take a metal sheet with the same thickness as that of the pipe, we cut out peculiar covers from it, weld them where the thread was not made.
4. In the center of the covers we make two holes - one of them along the circumference of the nozzle, the second - along the circumference of the jet. Inside the cover next to the jet, we drill a chamfer so that we get a nozzle.
5. We connect the generator to the heating system. we connect the branch pipe near the nozzle to the pump, but only to the hole from where water flows under pressure. We connect the second branch pipe to the inlet to the heating system, while the outlet must be connected to the inlet of the pump.

The pump will create pressure, which, acting on the water, will force it to pass through the nozzle of our design. In a special chamber, the water will overheat due to active mixing, after which it is supplied directly to the heating circuit. In order to be able to regulate the temperature, the do-it-yourself vortex heat generator must be equipped with a special locking device located next to the nozzle. If you cover the constipation a little, then the structure will move water through the chamber longer, therefore, because of this, the temperature will rise. This is how this kind of heater works.

Increasing productivity

The pump loses thermal energy, which is the main disadvantage of the vortex generator (at least in its described version). Therefore, it is better to dip the pump in a special water jacket, so that the heat emanating from it also benefits.

The diameter of this jacket should be slightly larger than that of the pump. We can use for this, according to tradition, a pipe cut, or we can make a parallelepiped from sheet steel. Its dimensions must be such that all elements of the generator fit freely into it, and the thickness must be such that it can withstand the working pressure of the system.

In addition, heat loss can be reduced by installing a special tin casing around the device. The insulator can be any such material that is able to withstand the operating temperature.

1. We assemble the following design: a heat generator, a pump and a connecting pipe.
2. We measure what their dimensions are and select a pipe desired diameter- so that all the details fit easily into it.
3. We make covers for both sides.
4. Next, we make sure that the parts inside the pipe are rigidly fixed, and also that the pump is able to pump the coolant through itself.
5. We drill an outlet, attach a pipe to it.

Note! It is necessary to place the pump as close as possible to this hole!

At the second end of the pipe, we weld a flange, through which the cover will be fixed to the gasket. It is possible to equip a frame inside the case to make it easier to install all the elements. We assemble the device, check how strong the fasteners are, check the tightness, insert it into the case and close it.

Then we connect the vortex heat generator to all consumers, check it again for tightness. If nothing flows, then you can activate the pump. When opening / closing the tap at the inlet, we regulate the temperature.

We warm the VTP

First of all, we dress the casing. For this, we take a sheet of aluminum or stainless steel and cut out a couple of rectangles. It is better to bend them along such a pipe, which has a larger diameter, so that a cylinder is eventually formed. Next, follow the instructions.

1. We fasten the halves together using a special lock used to connect water pipes.
2. We make a couple of covers for the casing, but do not forget that they should have holes for connection.
3. We wrap the device with thermal insulation material.
4. We place the generator in the casing and tightly close both covers.

There is another way to increase productivity, but for this you need to know exactly how Popov's miracle device works, the efficiency of which can exceed (not proven and not explained) 100%. We already know how it works, so we can proceed directly to improving the generator.

Whirlpool damper

Yes, we will make a device with such a mysterious name - a vortex damper. It will consist of plates arranged along the length, placed inside both rings.

Let's see what we need to work.

• Welding.
• Turbine.
• Steel sheet.
• Pipe with thick walls.

The pipe must be smaller than the heat generator. We make two rings out of it, about 5 cm each. From the sheet cut out several strips of the same size. Their length should be 1/4 of the length of the device body, and the width should be such that after assembly it remains free space inside.

1. We insert a plate into a vise, hang metal rings on one end of it and weld them to the plate.
2. Remove the plate from the clamp and turn the other side. We take the second plate and place it in the rings so that both plates are placed in parallel. Similarly, we fix all the remaining plates.
3. We assemble the vortex generator with our own hands, and install the resulting structure in front of the nozzle.

Note that the field of improving the device is almost limitless. For example, instead of the above plates, we can use steel wire, twisting it first in the form of a ball. In addition, we can make holes in the plates different size. Of course, all this is not mentioned anywhere, but who said that you cannot use these enhancements?

Finally

And as a conclusion - a few practical tips. Firstly, it is desirable to protect all surfaces with staining. Second, everything internal details should be made of thick materials, since it (the parts) will constantly be in sufficient aggressive environment. And thirdly, take care of a few spare caps that have different size holes. In the future, you will select the required diameter in order to achieve maximum performance of the device.
