The invention relates to a device for heating a liquid and can be used for heating buildings. The heat source for heating liquids having a cylindrical body with a cyclone accelerator liquid stream at the bottom, a braking device in the upper part of the housing, behind which is installed the bottom with an outlet communicating with an outlet via the overflow pipe, which is connected with the end of the cyclone coaxially it, the braking device is mounted for axial movement within the housing, which is provided with a rod placed on the axis of the housing with its free outlet end of the cyclone through the end of the heat generator. The technical result is to increase the thermodynamic efficiency of energy conversion.
DESCRIPTION OF THE INVENTION
The invention relates to devices for heating buildings and structures.
Known heat source / 1 /, containing a sealed spherical body with a heat exchanger arranged therein, a network pump, flow and return of heating duct from the shut-off valves. The disadvantage of this heat generator - high operating pressures up to 1000 bar.
The closest in technical essence is a heat source for heating fluids / 2 / having a cylindrical body with a cyclone, the liquid flow accelerator in its lower part, a braking device in the upper part of the housing, behind which is installed the bottom with an outlet communicating with an outlet via a bypass pipe which is connected with the end of the cyclone coaxially to it.
The disadvantage of this heat generator - it is difficult to change the thermal stress due to lack of opportunities regulation teploprozvoditelnosti heat generator that reduces the thermodynamic efficiency of energy conversion in the heat generator.
The purpose of the present invention - increase the thermodynamic efficiency of energy conversion.
This object is achieved in that the heat source for heating liquids having a cylindrical body with a cyclone accelerator movement of fluid in its lower part, a braking device in the upper part of the housing, behind which is installed the bottom with an outlet opening communicating with an outlet via a bypass pipe, end of the cyclone which is connected coaxially to it, the braking device is mounted for axial movement within the housing, which rod is provided with braking apparatus placed on the axis of the housing with its free outlet end of the cyclone through the end of the heat generator.
Because the brake assembly is mounted for axial movement within the housing by rods mounted on the axis of the body with the release of its free end from the heat source through the cyclone end, it is possible to smoothly change the working volume of the heat source, the magnitude of which the efficiency of fluid energy conversion depends heat t .e. provides the most efficient energy conversion conditions corresponding to specific conditions of heat, which causes the highest thermodynamic efficiency of energy conversion.
In the analysis of the prior art in order to verify the claimed novelty of the heat source is not found analogues listed a set of enumerated grounds. Consequently, the described technical solution meets the criterion of "novelty".

The drawing shows a general view of a heat generator for heating the fluid. The heat generator comprises a cylindrical housing 1 with a cyclone 2 - accelerator movement of fluid in its lower part. The upper housing 1 is set braking device 3, 4 provides for several ribs attached to the central hub 5. The braking device is mounted for axial movement in the housing 1, which is provided with a rod 6 located on the axis of the housing 1 with the release of its free end through the heat source end of the cyclone 2. During braking device 3 is installed with the bottom outlet 7, 8, communicating with an outlet 9 through a bypass pipe 10 which is connected with the end of the cyclone 2 coaxially to it. The bypass pipe is somewhat lower connection zone to the cyclone 2 is set additional braking device 10. On entering the cyclone 2 tangentially mounted an injection nozzle 11 with the outlet 12. |
HEAT WORKS AS FOLLOWS
When applying the liquid injection nozzle 12 through the liquid pressure of 0.4-0.6 MPa is directed into the cyclone 2, movement accelerator. When passing through the liquid inlet port 12 is partially heated by friction. In the cyclone 2 is an acceleration of fluid motion and twisting it. When swirling motion in cylindrical housing 1 occurs the fluid pressure change, causing an increase in fluid temperature. When passing through the brake device 4, the bottom hole 8, the kinetic energy of the fluid decreases, which causes further increase in liquid temperature. By moving the braking device 4 through 6 traction, pick the optimal value of the working volume of the heat source, providing the highest thermodynamic efficiency of fluid energy conversion into thermal energy corresponding to the specific conditions of the required heat.
For the manufacture of the heat source used standard equipment and materials in industrial environments.
CLAIM
The heat generator for heating liquids having a cylindrical body with a cyclone, the liquid flow accelerator in its lower part, a braking device in the upper part of the housing, behind which is installed the bottom with an outlet communicating with an outlet via the overflow pipe, which is connected with the end of the cyclone coaxially him characterized in that the braking device is mounted for axial movement within the housing, which is provided with a rod placed on the axis of the housing with its free outlet end of the cyclone through the end of the heat generator.
