DESCRIPTION OF THE INVENTION

The present invention relates to the field of heat engineering, in particular to devices for liquid heating, and can be used for heating buildings, hot water and other sectors of the economy.

Known heat generator comprising input swirling fluid device connected to one of the ends of the vortex tube body, inside which the opposite end mounted brake assembly and nozzle outlet of the heated liquid, the cavity of which the passageway is connected with an end of input twisting device (Patent RU 2045715 C1, 10.10. 1995).

Of the known heat sources closest to the claimed heat source is a hydraulic described in patent RU 2134381 C1, 10.08.1999. It comprises an input a twisting device connected to the vortex tube body, nozzle discharge heated liquid, the body of the vortex tube and the tube outlet of the heated fluid are installed on opposite sides of the input swirling device body of the vortex tube is designed as a widening of the entrance to the bottom of the vessel, the inner surface which is provided with at least two longitudinal grooves of the cylindrical shape, uniformly distributed around the perimeter of the cross section of the vortex tube body. Body cavity of the vortex tube is designed as a cone whose angle of taper is 1 to 15 °. Square openings, connecting the inlet with the swirling device body cavity of the vortex tube, a 2-6 times greater orifice area, which connects the inlet pipe swirling device with a heated fluid outlet, which is provided by an adjustable flow cross section area.

Known devices have a high enough efficiency.

This is due to insufficiently effective energy conversion process, the mechanism which performs an essential role anisotropic turbulence prevailing in the radial direction, induced by shear rates caused by a counter peripheral movement and paraxial strongly swirling fluid flow in the high static pressure radial gradient.

The technical problem to be solved by the proposed invention, - increasing the efficiency of the heat generator.

The technical problem is solved in that the heat source is a hydraulic comprising input swirling device, on opposite sides of which are located vortex tube, the housing of which is connected to the input swirling device and the nozzle outlet of the heated fluid, further comprising slot diffuser coupled to the vortex tube body and having an axial channel in the central part coaxial with the interior of the housing of the vortex tube and communicating with it, and coaxial (annular) channel, flow of which is connected to the interior of the vortex tube on one side and axial the other side of the channel, while the slot diffuser provided with blades, disposed in the annular channel. The vanes in the annular channel formed with radial or trailing edge twisting angle to the radial direction which changes the liquid to the opposite direction of rotation.

Such an arrangement provides a heat generator hydraulic intensification of the process of energy conversion in the heat source and, as a consequence, an increase in its effective efficiency.

Thus, the heat source is introduced into the hydraulic novel features in conjunction with known allow to solve the problem.

HYDRAULIC HEAT HYDRAULIC HEAT

The invention is illustrated by drawings, where Figure 1 is a hydraulic heat source, a longitudinal section, Figure 2 - an embodiment of the blade slot diffuser section AA.

The heat generator comprises a hydraulic (1) input swirling device 1, on opposite sides of which are located vortex tube body 2 which is connected to the swirl inlet device 1 and the discharge pipe of the heated fluid 3, a slit cone 4 connected to the housing 2 of the vortex tube. The diffuser 4 has a central axial duct 5 connected with the interior of the body 2 of the vortex tube and communicating with it, and coaxial (annular) channel 6 running part which is connected with the interior of the body 2 of the vortex tube on one side and with the axial channel 5 - on the other hand. 6 within the annular channel (2) has 7 blades, radial or formed with a twist off edge 8 at an angle to the radial direction which changes the direction of rotation of the fluid is reversed.

Heat generator hydraulic works as follows. Liquid is fed into the input swirling device 1 in which the fluid flow is accelerated and twisted, and then enters the inner housing space 2 of the vortex tube in which are formed two strong swirling fluid flow - the peripheral and axial, with the resulting law-separation strongly swirling flow and implementing thermodynamic processes in the field of mass forces with high radial static pressure gradient peripheral flow has a higher temperature than the axial flow.

The liquid flow, moving along the spiral slot in the direction of the diffuser 4 and passing it enters the annular channel 6 which dampens fluid flow velocity in a circumferential channel 7 between the blades 9 when executed radial. When the trailing edge 8 of the blades 7 at an angle to the radial direction of the flow changes the direction of rotation is reversed. Coming out of the annular channel 6, the axial flow of the liquid is accelerated. Accelerate the flow occurs due to the axial gradient of static pressure, which in the axial zone of the housing 2 is directed by one of the input device in the direction of the swirl diffuser slot 4. Coming out of the axial channel 5 in the axial zone of the housing 2, fluid flow moves in the direction of drainage pipe heated liquid 3. he interacts with the peripheral flow twisting them in the absence of circumferential velocity in the inlet duct 5 or unwinding - if the circumferential velocity opposite to the rotation of the liquid flow coming from the input device 1. After passing the swirl nozzle of the hot liquid outlet 3, the heated liquid is supplied consumer.

Using the blades 7 in the annular channel 6 leads to a drastic reduction in the circumferential speed of the peripheral fluid flow which causes an increase in the radial gradient of the static pressure in the cross section of fluid flow out of the axial channel 5, which leads to an increase in the axial gradient of the static pressure and, consequently, to increase the axial paraxial part of the flow rate. This causes an intensification of shear deformation and, as a consequence, increase the anisotropic turbulence prevailing in the radial direction on the boundary and separating the peripheral paraxial streams of liquid by increasing the difference between the axial liquid flow velocities at the boundary of the separation streams. Anisotropic turbulence significantly affects peripheral heating fluid flow, being part of the energy conversion mechanism in the heat generator, which leads to an intensification of growth of the energy conversion process in the heat source and, consequently, an increase in its effective performance.

When using blades with a twist 7 trailing edge 8 against the peripheral direction of the peripheral speed of fluid flow axial flow of fluid exiting the axial channel 5 becomes rotated at a peripheral speed in the direction opposite to the circumferential speed of the peripheral fluid flow. This contributes to a further increase in the shear deformation due to the difference of oppositely directed rotational speeds of the peripheral and paraxial streams and, consequently, to increase the anisotropic turbulence which increase leads to an intensification of the energy conversion process in the heat source and therefore, to further increase its effective performance.

Thus, the use of the proposed scheme can improve the hydraulic heat generator its effective efficiency.
