The invention relates to a power system and can be used for heating the liquid.

A device (patent of Russian Federation RU 2085273 C1, 27.07.97), including mixed case made from separate sections fastened together, at least two working chambers, which is installed with centrifugal wheels mounted on the periphery of the rings, and in the working chambers opposite each rotor is fixed to the stator. Working chamber communicated with each other by means of diffusers and provided with inlet and discharge pipes.

Known devices have disadvantages such as complexity of design, large axial load on the bearings, the complexity of the Assembly and the difficulty of alignment, resulting in low reliability and durability.

Known heat (patent RU 2142604 C1, class F 24 J 3/00, published. 10.12.1999), comprising a housing mounted in the housing of the generator on the drive shaft of the centrifugal impeller made multi-blade, the input and output window for the passage of fluid.

The disadvantages of the known pump-boiler are:

axial displacement of the rotor, leading to bullies;

- the collapse (condensation) caview;

- mountable chassis, the presence of a large number of servo controlling apparatus, connecting pipes and tubes, complicate the design and reduce the reliability.

The technical problem solved by the invention consists in creating a more simple technological device that has high reliability, durability and low build requirements. This problem is solved due to the fact that the heat generator includes a housing mounted in the housing of the generator on the drive shaft of the centrifugal impeller made multi-blade, the input and output window for the passage of fluid. Body heat generator made in the form of capacity to the drive shaft located vertically centrifugal impeller further comprises front and rear disks, forming flow channels, each of which has input and output apertures. The heat source is further provided with valve box, made in the form of a cylindrical Cup, which contains the output window and valves made of a given size and installed in front of the openings of the channels of the centrifugal impeller, which together with these holes form the sun the underwater shaft movably connected to the bearing housings, one of which is located coaxially with the cylindrical Cup and rigidly fixed at its bottom, and the other fixed on the top of the silo.

The above structural changes provide the following technical result:

1. By placing a heat source directly into the tank with the heated liquid removed:

- prefab housing boiler;

- pipeline system and equipment;

hydraulic resistance;

- unproductive fluid flows;

which leads to simplification of the structure and reduce energy consumption.

2. Due to the position of valve boxes in the suction cavity of the wheel, the formation of cavitation bubbles and their growth occurs in each channel of the wheel, and collapse (condensation) mentioned bubbles occurs outside of the wheel, resulting in improved durability and increased reliability.

3. The location in the vessel with the heated fluid tubular heaters expands options for space heating by circulation of liquid or air through the heaters or water directly from the tank.

In Fig.1 shows a longitudinal resolution B (Fig.1), cross-section of the valve box on the axes of the input window.

The heat source comprises a tank 1, which is installed on the drive shaft 2 of the working of the centrifugal multi-blade wheel 3, consisting of anterior disc 4 back disk 5 and 6 blades, between which is formed a flow channel 7, each of which has input and output holes. To the vessel attached valve box 8, which is made in the shape of the glass. On the cylinder of glass along the perimeter of the executed input 9 output 10 boxes that are located in two tiers. The output window 10 and the valve 11 are in the top tier and installed with a gap in the suction cavity of the wheel 3 opposite the inlet channels 7, and the input window 9 are located on the bottom floor and are located outside of the wheel 3. At the bottom of the Cup 8 is fixed supporting body 12, which is located coaxially to the cylinder of the Cup 8 and adjustably connected to the end of the drive shaft 2, the second end of the shaft 2 is installed in the bearing housing 13, which is fixed on the lid of the container 1. The tank 1 is equipped with valves 14 and 15 and tubular heating elements 17, the working part of which is located inside the tank 1, and the holes 18 and 19 on the outside of the tank 1.

Heat works sleduushemu 7 periodically closed by a valve 11 and open Windows 10. The duration of the closing and opening of inlet channels 7 set the window sizes of 10 and a valve 11. At the time of closing of the inlet of each channel 7 volume of liquid present in the cavity of the channel 7, due to the inertia force and the centrifugal force separates from the wall of the valve 11, there is a break in the continuity of the liquid, which is accompanied by a sharp decrease in pressure in the cavity of the channel 7, which is much below the saturation pressure of water vapor at a given temperature, and the liquid begins to boil, forming cavitation bubbles and their growth to the final dimensions. Perticaia fluid passes through the gaps between the glass 8 and the wheel 3 in the cavity of the channel 7, which is subjected to cavitation. During the opening of the inlet channel 7 of the cavity through the outlet is thrown out by centrifugal force and at high speed cavitation fluid volume, and simultaneously through the inlet cavity of the channel 7 is filled with new fluid volume 16 of the container 1. The ejected amount of liquid collides with a mass of liquid 16 in the path of its movement, including cavitation bubbles released previous 7 channels. In the area of the collision occurs due to the increased pressure, the compression of the floor the CSOs heated liquid 16 of the container 1. The heat from the heated fluid 16 is made either through a hot wall heaters 17, passing through them, the air or fluid for space heating, or through valves 14 or 15 produce a selection of heated liquid 16.

thermostat sets the temperature interval of operation of the heat source, which is favourable for the reduction of energy consumption for the formation of cavitation bubbles.

The proposed generator can be docked with a water turbine, wind turbine and other energy sources to provide heat in the room as warm air or water.

The heat generator, comprising a housing mounted in the housing of the generator on the drive shaft of the centrifugal impeller made multi-blade, the input and output window for the passage of fluid, characterized in that the housing of the heat generator is made in the form of capacity to the drive shaft located vertically centrifugal impeller further comprises front and rear disks, forming flow channels, each of which has input and output apertures, and the heat source is further provided with valve box, made in the form of a cylindrical Cup, which contains centuries centrifugal impeller, together with these holes form a suction cavity of the centrifugal impeller, the tank is provided with a tubular element, and the ends of the drive shaft movably connected to the support buildings, one of which is located coaxially with the cylindrical Cup and rigidly fixed at its bottom, and the other fixed on the top of the silo.
