The invention relates to heat engineering and can be used as a source of thermal energy for heating and hot water for heating the process liquid.

Known liquid heat generator (see patent RU N2148754, IPC F 25 B 29/00, publ. 23.07.98 year), which includes a housing with an outlet pipe and connected with the camera body twist with tangential openings and the inlet nozzle. Luggage twist to the input nozzle is made double chamber in the form of two concentrically arranged one within the other chambers twist.

The disadvantages of this device are the complexity of the design due to the presence of two cameras twist with multiple entrances, large size, low heat output.

Known heat source and a device for heating the liquid (see patent RU N 2045715, IPC F 25 B 29/00, publ. 26.04.98 g)adopted for the prototype. The heat source includes a housing with a cylindrical part of the cyclone, the end side of which is connected to the cylindrical part of the body, the basis of which, opposite the cyclone mounted brake device. For the brake device has a bottom with an outlet that communicates with the outlet pipe connected to the cyclone through the bypass pipe.

The disadvantages of the prototype are low teploproizvoditelnost is when there are long sections, where the fluid is moving with a decrease in kinetic energy without releasing heat, the complexity of the design due to the presence of several functional elements that are structurally executed sequentially, large size.

The invention solves the problem: increase the heat output.

The technical result obtained by carrying out the invention is to simplify the design, with a simultaneous decrease of metal, and dimensions.

This technical result is achieved that the heat source for heating the liquid containing the pump body, the cyclone, the bottom with the outlet, the inlet, outlet, what's new is that the body is made entirely cylindrical, inside of which are placed coaxially cyclone, representing two cones of different heights, United equal grounds, and housing and cyclone form a two-chamber cavity and the hole bottom is connected a by-pass pipe with the pump inlet and the outlet is located on the cylindrical surface of the shell.

The cyclone can be accomplished with the possibility of axial movement relative to the body.

Performing a heat source in the form of a cylindrical body with two-chamber cavity formed by the inner cylindrical walls of the casing and to the practical surfaces of the cyclone, made in the United equally cones of different heights, due to:

first, the need to reduce the overall dimensions of the boiler and simplify the design by composition of several functional units of the heat source within the cylindrical body;

secondly, in the scheme of the heat generator is provided to increase the heat output due to the exclusion of extended sites, where the fluid moves with the decrease of kinetic energy without releasing heat.

In the first chamber formed by the inner cylindrical surface of the housing and the conical surface of the cyclone with greater height is twisting coming through the tangentially located inlet pipe of the fluid flow and its promotion with decreasing reduced cross-section to the gap between the edge formed by the connecting edge of the base of the cone and the wall of the housing. The main heat release occurs in the area of the cylindrical surface of the housing by friction forces. Moreover, the process of heat release is activated by moving the rotating fluid flow and reduce the flow area between the housing and the cyclone, as the pressure increases as it approaches the smallest gap. The most heated fluid layer from Agen closer to the walls of the housing, less heated layers closer to the cyclone.

The second cyclone cone, located mirror relative to the first, due to the need for the development of a sustainable pronounced V-shaped fluid flow, which is formed from fluids with high speed, entering the second chamber, formed by the inner cylindrical wall of the housing and the surface of a cone with a smaller height and bottom.

The perform of the bottom end of the cylindrical housing with the outlet connected a by-pass pipe with the pump inlet and the outlet branch pipe, located on the cylindrical surface of the shell due to:

first, the need for braking promoted under the pressure of the fluid flow and removal of less-heated layers of liquid through the outlet, then the bypass pipe to the intake of the pump to re-circulate through the heat source. The most heated liquid layers, which are located near the walls of the cylindrical housing through the outlet come in direct pipeline heating system or hot water;

secondly, in case of emergency situations of unexpected surges of fluid pressure in the system connected to the heat source, the outlet holes made in the bottom, with the inlet of the pump allows the isite consequences arising hammer.

The heat source for heating the liquid can be accomplished in two ways: without the possibility of axial movement of the cyclone relative to the cylindrical body and with the possibility of the above move.

The implementation of the cyclone with the possibility of axial movement relative to the cylindrical body caused by the necessity to adjust the volume of the chambers located on both sides of the ribs formed by the boundary of the bases of the two cones to ensure optimal performance on the heat output.

Technical solutions with the features distinguishing the claimed solution to the prototype, is not known and obvious manner from the prior art do not follow. It can be considered that the claimed solution is new and involves an inventive step.

The invention is illustrated by drawings, where

Figure 1 shows a General view of a heat generator for heating the liquid cyclone without the possibility of axial movement relative to the body,

Figure 2 - section a-a,

Figure 3 is a variant of the heat source for heating the liquid cyclone with the possibility of axial movement relative to the body.

The heat source for heating the liquid cyclone without the possibility of axial movement relative to the housing consists of a cylindrical body 1 made of standard pipe, cover 2, the arrangement is authorized in the upper part of the housing 1, the bottom 3 with the outlet 4 located in the lower part of the housing 1, a cyclone 5, rigidly connected to the cover 2 and is made in the form of two United by their bases of cones. The outlet 4 of the bottom 3 is connected through the bypass pipe 6 to the inlet of the pump 7. The housing 1 and the cyclone 5 form two chambers 8, 9 of unequal volume, and the volume of the chamber 9 located in the lower part of the housing 1 is less than the volume of the chamber 8. The outlet 10 is placed on the cylindrical surface of the housing 1 in the lower part of the chamber 9. Inlet pipe 11 is placed tangentially relative to the housing 1 in its upper part.

In the second embodiment, a heat source for heating the liquid cyclone 5 at the apex of its conical surface has a threaded surface 12. Response threaded surface is made in the cover 2, which provides axial movement of the cyclone 5 relative to the housing 1 and allows you to adjust the volume of the chambers 8, 9.

The generator works as follows.

Under the pressure of the fluid through the tangentially mounted relative to the housing 1 inlet pipe 11 into the chamber 8 of the cylindrical housing 1 and a spiral emitting thermal energy moves with the increased pressure to the smallest gap between the housing 1 and the cyclone 5, placed on the border of the chambers 8, 9. Speed while crossing the border, 8, 9 increases with odnovremennym the allocation of additional thermal energy. Next, swirling the liquid moves V-shape inside the chamber 9, bounded by the cone with the smaller height of the cyclone 5, housing 1 and the bottom 3. Less heated layers of liquid through the outlet 4, the bypass pipe 6 to the input of the pump 7 to re-circulate through the heat source. The most heated layers of liquid through the outlet 10 comes into direct pipeline heating system or hot water.

In the second embodiment, a heat source for heating the liquid through the threaded surface 12 of the cyclone 5 is the possibility of axial movement relative to the housing 1, which allows you to change the volume of the chambers 8, 9 when debugging the optimal parameters of the heat generator.
