DESCRIPTION OF THE INVENTION
The invention relates to heat engineering and is designed to generate heat differently than in the combustion process, and can be used for heating in various industries.
Known heat generators, comprising a pump assembly connected to the water supply flow directed under pressure into the jet machine, in which the mechanical change flow rate (SU 1703924, IPC 5 F 24 H 3/02, opubl.1992 g, RU 2045715, IPC F 6 25 B 29/00, opubl.1995 city, RU 2161289, IPC 7 F 24 H 3/02, opubl.2001 g).
The operation of these devices is based on the creation of the expiry of the jet of fluid and its heat to disperse in the jet device arising due to the centrifugal effect and the occurrence of cavitation bubbles.
A disadvantage of such devices is the low efficiency, due to insufficient supply of heat to the coolant, and a higher noise caused by cavitation processes in the device.
The closest in technical essence to the claimed and accepted as the prototype is a heat source (RU 2161289, IPC 7 F 24 H 3/02, publ. 2001) containing the pump suction port is connected to the output of the jet device and the pressure port is connected creating a pressure gradient node whose output is connected through an expansion chamber with an entrance of the jet device.
Such an arrangement provides improved fluid heating efficiency due to the centrifugal effect that causes not only linear, but the centripetal acceleration of particles in a jet apparatus.
However, when using such a heat generator occurs insufficient supply of heat to the coolant, which reduces heating efficiency and increased noise caused by cavitation processes.
The object of the invention is to improve the efficiency of heating fluid by providing a dual-phase transition (liquid - vapor - liquid), which yields a high-speed vapor stream (steam with cold large linear accelerations) and conversion of kinetic energy of the steam flow to the thermal energy of condensed liquid.
This object is achieved by improving the heat source comprising a pump suction port connected to the output of the jet device and the pressure port is connected to a pressure gradient node whose output is connected through an expansion chamber with an entrance of the jet device.
This improvement consists in that the pressure gradient creation unit is designed as a steam generator, the inner surface of the jet apparatus is provided with elements of a pair of braking, the central portion of the cavity jet apparatus has a connection node to an input of the thermal load, the suction inlet of the pump is connected with the periphery of the cavity of the jet device.
In addition, the pump suction inlet may be connected to a connection node output heat load.
In addition, steam braking elements can be made in the form of protrusions and depressions on the inner surface of the jet apparatus.
Furthermore, a heat generator may be provided with a node isolation liquid stream formed as a container, a cavity which is divided by a partition into two parts by means of one of which the central portion of the cavity of the jet device is connected to the node thermal load input connections, and through another part of the suction port of the pump is connected with the periphery of the cavity of the jet device.
In addition, the peripheral portion of the cavity of the jet device may be connected to the cavity assembly junction part gap, the inlet of which is located at a tangent to the inner surface of the jet apparatus.
Execution unit creating a pressure gradient in the steam generator provides a high-speed vapor stream which accelerates in the expansion chamber to provide heat generator beskavitatsionny mode. The pressure gradient for vapor is determined experimentally by taking into account the width and length of the slots, the average operating temperature of the heat generator, and a pump output.
Purchasing the inner surface of the braking elements of the jet device allows steam mechanical braking couple expanded when exiting the node for creating a pressure gradient condensing it into liquid. The kinetic energy of a high-speed flow of steam is converted into thermal energy of the condensed liquid.
Supply central cavity jet device connection node to an input heat load enables the user to direct the heated fluid from the central cavity of the jet device.
Connection pump suction pipe with the peripheral part of the cavity of the jet device provides power to the liquid inlet of the pump without residues non-condensed vapor, which improves the operation of the pump (increases the fluid delivered by the pump pressure, and its performance, which increases the efficiency of the heat source).
A compound pipe with a suction pump unit connected to the output heat load enables the spent coolant return, and thus, when installing the heat generator in the thermal load to provide a closed circuit operation.
Implementation of braking elements in the form of a pair of protrusions and depressions on the inner surface of the jet device provides effective inhibition of steam for heating and condensing liquid jet apparatus with tech braking elements. This provides a rotary-translational (to avoid cavitation effect in the selection of a peripheral portion of the liquid jet apparatus) resulting condensed liquid movement.
Supply heat source node isolation liquid stream formed as a container, a cavity which is divided by a partition into two parts by means of one of which the central portion of the cavity of the jet device is connected to a connection node to an input of the thermal load, and through another part of the suction port of the pump is connected with the periphery of the cavity jet apparatus, the system provides a compact layout of fluid flow and thereby reduces the radiated surface and metal pipes.
Compound peripheral portion of the cavity with a portion of the jet device cavity gap junction node, wherein the inlet is located at a tangent to the inner surface of the jet device, allows to prevent residues in the pump cut uncondensed steam and condensed liquid stream tangentially to avoid cavitation effect.

The heat generator comprises a pump 1, a suction nozzle 2 which is connected to the output of the jet device 3 and the discharge nozzle 4 is connected to node 5, creating pressure gradient, the output of which is connected through the expansion chamber 6 to the input of the jet device 3. Node 5 creating a pressure gradient is in the form of a generator steam, which is a barrier with narrow slits, the total length and the pressure gradient determine the conditions of steam generation. The inner surface of the jet device 3 is provided with a pair of brake elements 7 and the lower central part of the cavity of the jet device is connected to the node 8 input heat load 9, the suction nozzle 2 pump 1 is connected to the peripheral part of the cavity of the jet device 3.

The fluid pump 1 under pressure through a discharge nozzle 4 is supplied to the node 5, creating a pressure gradient in which the formation of a high-speed steam flow, accelerating at the exit of the unit 5, extending in the chamber 6. The amount of acceleration determines the amount of the acquired kinetic energy of the steam. The vapor stream enters the jet device 3, in which the inhibition of its braking elements 7. In the reaction of steam with the braking elements 7 made its condensation. This takes the steam kinetic energy into thermal energy of the fluid. Thus, due to the double phase transition (liquid - vapor - liquid) heat input is performed to the liquid. The resulting hot liquid flow from the peripheral portion of the cavity of the jet device 3 (to avoid falling into the non-condensed steam pump 1) is cut off at a tangent slit 16 (to avoid cavitation effect) and fed into unit 11 of the 14 interchanges.
