The invention relates to the field of power engineering and can be used in Autonomous systems of heating and hot water. The known device analogs using the changes in physical-mechanical parameters of the working environment, such as pressure, volume and velocity to produce thermal energy: ultrasonic activator (RF patent No. 2054604 of 20.02.1996,), the device for heating the liquid (patent RF №2162571 from 27.01.2001,).

Device (patent No. 2054604) contains two or more series-connected working chamber, each of which has a pump impeller of a centrifugal pump, is bonded on the periphery of the rotors in the form of perforated rings, coaxial in which the housings of the working chambers opposite each rotor is fixed to the stator. Working chamber communicated with each other by means of diffusers. The last working chamber is connected with the first chamber circulation loop, equipped with a throttle element.

The disadvantages of the known devices: low-tech one-time Assembly of the rotor, the housing parts, the stator; the difficulty of ensuring mutual alignment of the mating parts. Installation of fixed working body at the outlet of the rolling of the working body leads to the transfer of the whole pressure of the impeller in a small area fixed working body, increasing the th wear.

The device for heating the liquid (patent No. 2162571) contains a heat source consisting of a body having a cylindrical part with two built-in brake systems, and the accelerator of the fluid made in the form of a cyclone (camera twist), a pump connected to the heat source through the injection nozzle, and a heat exchange system.

The disadvantages of the known devices are: unstable heat output of the heat generator; a shortfall potentially achievable heat at its output due to the presence of two series-connected braking systems, considerable dimensions, intensity and cost, caused by the length of the cylindrical body of the heat generator.

As the closest to the invention by the combination of essential features of the technical solution of the prototype adopted generator drive cavitation, comprising a housing in which are relatively movable bodies, the input and the output of which is hydraulically communicated through the circulation channel with a throttling element. Working bodies, at least one of which is associated with the driving motor, made in the form of opposed spaced disks mounted with guaranteed clearance between their ends (patent RF №2201562, CL F 24 J 3/ 00 dated 27.03.2003 year).

In this halogenerator the e moveable disk fixed on the shaft end of the actuator, forming a cantilever structure that rotates with the shaft and disc with great speed for the formation of intense vortices in the cavity with opposed fixed disk causes a large axial load and run out of the bearings, which, in turn, modifies the desired gap between the end faces of the rolling (“console”) and stationary disks, leads to disruption of throttling and circulation effect, especially when large thermal capacity, to reduce the heat output and reliability of the heat generator.

The required technical result of the invention is to provide a stable heat output by creating conditions for sustainable hydrodynamic cavitation while simplifying the structure of the heat generator and its manufacturing technology to ensure the efficiency of its use with drive motors from 7.5 to 160 kW while increasing efficiency of the energy conversion efficiency of the actuator, reliability, improving operation and maintenance, lower weight and size, limited, for example, the dimensions of the transported trailer, kung, of the container.

The required technical result of the invention is achieved by a new device heating water with heat pump type, consisting of a body with suction (inlet) pipe DL the tangential inlet and discharge (output) pipe for horizontal drain to consumers located in the housing, at least one means for the acceleration of the fluid that is made in the form of an impeller mounted for rotation under the action of the actuator, and a single means for braking the movement of the liquid, made in the form of a conical directing vanes with plates that are parallel to the walls of the cone.

The impeller of the centrifugal type consists of two permanently sealed transverse ties disks, the first of which is vertical to the axis of rotation of the plane closer to his face, contains accelerating liquid evenly circumferentially distributed ribs, below which, parallel to the axis of rotation, is a through hole for communication workers of cavities of the heat generator. The second disc is a flat vertical ring, with his pads on the ribs of the first disk. To do this, its a plane adjacent to the edges of the first disk, is made at an angle to the vertical plane.

By process connections side adjacent the inner surfaces of the two disks in the impeller, almost on the same radius with its through-hole formed at an angle to the side surface of the impeller nozzle cross-section, decreasing to its periphery, which are the accelerators of the fluid at the exit of the zone p is skogo speed and fluid pressure.

On the face of the circumference of the impeller made several external channels-helices with grooves arranged at an angle to the vertical axis of the wheel for maximum speed twisting and movement of water toward the periphery of the body.

The inner surface of the shell in the zone of rotation of the impeller, coaxial him, shrunk the disk in the form of a flat to the axis of rotation of the ring located on its inner surface such as spirals with grooves forming with the grooves of the spiral impeller narrow slit of variable cross-section for passage being pushed out of the nozzles of the liquid, compression, acceleration and heating. The impeller is installed on the shaft of a drive motor with adjustable gaps “a” and “b” between its side surfaces and covers entry and exit of heat through the movement of the impeller along the shaft (Figure 1). Rotating the working wheel with spirals at the end, a stationary disk with spirals made opposing spirals of the impeller, the grooves and the gap between them fulfill the role of the cavitator, providing an intensification of process of heat production in the collapse of cavitation cavity of a rotating liquid.

The impeller diameter, the distance from the end cap inlet and outlet of the housing, the dimensions of the grooves and slots are defined heat the OIC capacity of the device.

At the entrance to the building there is a braking device, which ensures rapid increase in the peripheral speed tangentially supplied through the suction nozzle of the liquid in the direction of impeller rotation for tightening and subsequent acceleration by suction from the cavity of the body of water through the nozzle rotating discs and rapid heating with additional compression when passing through the gap.

Increasing the efficiency of heating the liquid contributes to the braking device installed at the outlet of the heat generator connected via a discharge line from the heat exchanger.

To accelerate heat exchange system and energy saving to the backbone of the heat exchanger attached heat accumulator containing a volume of water heated by the heat source at night with low electricity tariffs. The device for heating the liquid can be operated in automatic mode, which is equipped with a microprocessor-based programmable meter-pressure regulator in conjunction with an input thermocouple for measuring temperature, pressure and water flow rate using standard sensors.

The proposed solution differs from analogs and prototypes by the presence of new elements: the impeller of the two disk special profile that contains N. the end of the spiral groove and the nozzle, fixed disk with the spiral groove tangential suction nozzle, one braking device output and their relationship with other elements of the device. At the entrance of the heat generator no brake device.

These differences allow to draw a conclusion on the conformity of the proposed solutions to the criterion “novelty”.

The comparison of the proposed solutions with other similar solutions shows that the impellers with blades, a blade elements and grooves (grooves) between them is known, for example in the heat for heating the liquid (patent No. 2197688 from 27.01.2003,). However, these elements do not have impellers spiral groove and nozzle, pulling, twisting and accelerating the flow of fluid to achieve the required technical result. Thus, the claimed technical device meets the criterion of “inventive step”.

The proposed device consists of the building blocks of heat engineering, hydraulics, electrical engineering and automation. Therefore, the invention meets the criterion of “industrial applicability”.

Figure 4 shows the impeller Assembly with the form and end with spirals 26 and (b) of the plan.

Figure 5 shows the cross section of the stationary disk 5, plated on the inner surface of the cylindrical part of the housing 1, with the slots 27.

Figure 6 shows the conditions for the occurrence of friction of fluids in zones C and D of rotation of the impeller.

The heat generator is connected via a shaft 13 by a motor 28 and a heat exchange system that includes highways, shut-off and regulating valves 14, 15, 29, the heat exchanger 16, the surge tank 17, a pump 18, the heat accumulator 30.

A device for heating the liquid as follows.

When the pump 18, the liquid, such as water, through the suction nozzle 8, the inlet 9 of the housing 1 at a pressure of 5-6 ATM podes is in the suction cavity 10 tangentially to the horizontal axis of the heat source (Fig 1 and 2). When the engine is restarted 28 due to the rotation of the impeller 4 through the shaft 13 occurs, the circulation of water from the cavity 10 through the through hole 24 (Fig 3 and 4) of the impeller, the hole 11 of the cover 3 of the heat generator, cone straightener apparatus 6, the discharge nozzle 12 to the heat exchanger 16. At the same time due to the spin of the water by the ribs 22 and the coils 26 of the impeller (Figure 3) in its peripheral zone is the circulation of water through the slit 19 formed by the grooves 25 of the coils 26 of the rotating disks 20 and 21 and the grooves 27 of the stationary disc 5 (Figure 5), increasing the friction force of the water flow along the side surfaces of the impeller in zones b and G (6). The particles of water adjacent to the impeller under the action of developing them to the centrifugal force due to the ribs 22 of the disk 20, strive for inner periphery of the housing 1, and the particles adjacent to his covers of the input 2 and output 3, moving from the periphery to the center (6). This provided the desired pressure at the inlet to the nozzle 23 conducive to the absorption of their water from the stored kinetic energy, then popping it in the slot 19 and then through the holes 11, the discharge nozzle 12 into the heat exchange system 16. At a meeting of the particles of the water comes a gap in the continuity of the environment, which leads to the formation of hydrodynamic cavitation water with subsequent podsypaniem fluid and ejecta is m heat on the border of the rotary impeller 4 and the stationary disc 5 without the use of special cavitator. This mode correspond to the calculated value of the speed of rotation of the impeller, the water pressure and the internal volume of the cylindrical body heat source. The power of friction of the impeller on the liquid can be determined as follows (smfg).

Elementary friction force dR acting on the element surface of the impeller dF rotating with velocity U in a medium with a density of γequal [1]

where Cƒ - coefficient of friction.

Elementary power of friction on both sides of the impeller dNgequal to

Integrating (2) over the entire surface of the impeller into account the formula (1) allows to obtain the frictional capacity in the areas of rotating impeller

where D is the impeller diameter.

Defined by expression (3) power of friction of the impeller of the fluid is equivalent to the heat output of the heat generator. The mechanism for obtaining thermal energy is the so-called phase transition of higher genus [2, 3], i.e. the interaction with the atoms of water of free electrons produced by the decomposition of water in the cavitation process, wresting from the atom positively charged particles - electrino turning into photons, carrying heat.

Pre-heated water through the open which I cover exit 3 (Figure 2) is fed to the braking device, containing cone straightening machine with plates 7, which provides the braking fluid twisting moment and zone hidrocapital for further intensification of heating water by increasing its force hydraulic shock on the inner surface of the cone directing vanes and plates. Then there is the further displacement of water to the heating nozzle 12, which, overcoming the resistance of the pressure-regulator valve 15, is sent to the heat exchanger 16 and then into the expansion tank to the pump 17 and 18, providing heating and hot water consumers, and through the valve 29 when the need arrives in the heat accumulator 30. The pump 18 is required only for short-term use during the initial filling of the system of heat exchange water and the completion of its partial losses.

After stopping the generator, and hence the impeller necessary temperature unloading the internal cavity of the device to prevent burning his face seal is provided by the flow of liquid through the through holes 24 of the impeller.

Conducted on prototypes of IPICO of the claimed device experiments and mathematical (computer) modeling elements of the generator [4] has allowed to establish their optimal settings. the AK, for a heat source of the heat capacity of 75 kW maximum dimensions of the body together with straightening apparatus is 560 mm, impeller diameter 300 mm, the distance of the impeller from the cover of the entrance and exit 62 mm, its diameter through holes 20 mm, distributed over the circumference of the wheel 36°cone directing vanes 30°. Each helix of the impeller and a stationary disk is made at an angle of 12° the horizontal axis of the heat source and contains 95 and 96 of the grooves with a radius of 2.2 mm in the wheel and the disk-ring, respectively, uniformly distributed along the length of the spiral.

When the individual changes, the above parameters during experiments was observed unstable turbulence in the body of the heat source, which are carried away in the discharge nozzle, which leads to the destruction of the stability of hidrocapital fluid and reduce the temperature of heating water.

At JSC Istra pilot plant “Ulemas” prototype of the claimed device using the capabilities of industrial production elements of the heat generator of TS-1 with the above options.

This heat combined two functions: heating and intensified the flow of the liquid in the heat exchange system, and the role of the cavitator perform a rotating impeller, not odwazny disk-ring, them with spiral grooves forming between the wheel and the disk gap variable section.

The tests of this sample showed that the efficiency of water heating has increased by 1.8 times with the same capacity of the pump, motor and heating efficiency in comparison with analogues and prototype.

In addition, the operational reliability of the claimed device has remained at a high level, because it used only one brake system at the output of the heat source and no cavitator, which allowed to reduce its size and weight.
