On the front wall of the chamber 6 at its periphery in the form of a nozzle carried dispersed on the peripheral diameter of the chamber 6 through passage throttling channels 7. Impeller 1 as a source of energy of fluid flow is set into the cone-shaped nozzle unit 8 in the zone of its greatest diameter shaft and communicated to a drive motor 9 ( engine in Figure 1 are not shown). Output channel 10 of the nozzle unit 8 is located in its small-diameter end, communicates with external hydraulic system 11, heat removal, the output of which is communicated with the suction port 12 of the nozzle unit 8, a supply fluid to the inlet cross-section 4 of the impeller 1.

In this embodiment the inlet section 4 of the impeller 1 is satisfied by the arrangement of the drive shaft 9.

2, 3 and 4 are embodiments in which the input section 4 of the impeller 1 positioned on the inner cavity 13 of the nozzle unit 8.

2 is provided with an additional heat source tapered nozzle assembly 14 disposed oppositely unit 8 on the other end side of the impeller 1. In this case nozzles 7 can be executed with two end faces of the impeller of the pressure chamber on June 1.

The output channel 10 nozzle device for increasing the pressure between it and the suction channel 12 may be performed in the nozzle unit 8 between the location area of ​​the rim of the impeller arrangement 5 and the end of the nozzle 1, a small diameter device. See, for example, 2, 3 and 4, showing additional output channels 15 for external hydraulic complex structure, such as providing heat, hot water and the presence of the hot source, such as pressurized water from the primary circuit internal nozzle device - the cavity 13.

To ensure the flow of internal circulation between the impeller and the interior cavity 13 of the nozzle unit 8 inside cavity 13 adjacent to the nozzle axis of the apparatus, it communicates with the input section 4, the wheel 1 via at least one additional throttling passage 16 and / or 17. See FIG. 2a and 17 and 18, see Fig. 3 and 4.

Additional channels 17 and 18, formed coaxially axis of the nozzle unit 8 form together with the suction channel 19, mixing chamber and the recirculation flow stream coming from an external heat source to the hydraulic system 11 (Figures 2 and 4 show examples of the technical solutions of the hydraulic system of a plurality of options) .

The internal cavity 13 of the nozzle unit 8 in the embodiment can be communicated with the impeller 1 additional opening into the blade area of ​​20, additional spray throttling channels 21, which reduces the probability of failure of the mode wheel 1 in the high temperature zone where the working fluid in the wheel input is a two-phase (vapor-liquid) structure.

In the simplest embodiment, the nozzle 7 satisfied combined into a common ring shaped gap 30, for example, diffuser type, as shown in Figure 7, in the form of a flat slit, the slit type nozzle or a venturi confuser. Such nozzle technology and easy to manufacture, minimize external vibration activity TEPLOAGREGAT but often optimal for implementing the limited tasks for the application of the heat generator. The optimal number of tasks, such as decontamination liquid, ensuring intensive mixing of liquids and solids for intensification of chemical processes, problem solving cleaning the outside of the hydraulic system and it contains details and and and tasks improve reliability when working in contaminated liquids preferably solved when the nozzle in the form of profiled throttling apertures 31, channels 32 or slots 33 cm. 8 and 9, fluid flow guides W relative to the circumferential velocity vector U D 90 ° + where It lies in the range of + 80 ° ...- 30 °, starting from the condition of maximum efficiency and ensure the necessary pressure between the outlet passage 10 of the nozzle unit 12 and the suction port of the impeller 1.

In embodiments, the periphery of the impeller are made of liquid flow deflecting projections 34 and additional acoustic resonators in a vortex generating chamber 35 or slots 36 cm. 7 and 8, directly affecting fluid flow W Exiting the nozzle in the form of slits 30, holes 31, channels 32 or slots 33. In the simplest case, = 0. at > 0 increases the tangential component of the flow velocity entering the nozzle unit 8 and thereby increasing the speed of fluid in the internal cavity 13 of the nozzle apparatus, see. The velocity diagram in Figure 9. at <0, increases the pressure between the channels 10 and 12.

For the convenience of connecting the various subsystems of the heat generator to the external hydraulic nozzle unit may be provided with two or more suction 12 and output 10, 15 channels.

HEAT WORKS AS FOLLOWS

After connecting channels 10 and 12 heat-generator to an external hydraulic system 11, see FIG. 1, filling its coolant, for example water, and remove air from the cavity 13 and the hydraulic drive motor 9 rotates the shaft of the impeller 1. This pressure arises in the chamber 6 and 7 through a nozzle in a nozzle unit 8 with high circumferential speed enters the liquid moving in the direction of the minimum diameter of the nozzle apparatus. One portion of the liquid flow passes through the channel 10 to the hydraulic system 11 and then returns to the suction passage 12 and further into the impeller 1, and another part flow having an increased angular velocity, moving on the nozzle unit axis to the wheel 1 toward the circumferential flow chamber 13 and channels 16 through the throttling (21) is fed into the input portion 1 of the wheel, creating an internal liquid recycle stream in the chamber 13. this causes the continuous nature of the motion in the fluid heat dissipation due to cavitation and vortex processes in it, which is intensified by the action of the resonators 24 26, 27, 35, causing a wave of liquid molecules vibrational excitation, and a vortex generating projections 34 at the impeller 1, reducing the pressure at the nozzle 7, executed in the embodiments shown in Figures 1, 2, 4, 7 ... 9. The intensity of the heat is given the task and the relationship between flow rate of internal circulation in the heat exchanger and the circulation flow through an external hydraulic system that provides job hydraulic resistance of the circuits known in the hydraulic means. The intensity of the heat. It is possible to connect the boiler hydraulic systems for various applications and structures. Mixing chamber 19 and passages 16 and 21 increase the suction capacity of the wheel when running on a two-phase fluid.

For example, in Figure 3 of the nozzle unit 8 through the resonator 22 and the axial duct 10 communicates with boiler 38 along its axis, that as a whole maintains a vortex motion of a fluid on a large external hydraulic station; to the high-pressure outlet duct 15 is connected a heat exchanger 39 of the air heating. By boiler 38 connected to the heating system 40 and through the additional heat exchanger 41 connected to the device 42. At the same time hot water to the boiler 38 can be connected to several heat generators for backup purposes and heat flow control applied in the hydraulic system.

In the presence of an electrical energy source 29 AC or DC 29 additional adjustable heating liquid is carried out by passing an electric current through the central ionized fluid circulation flow in the core cavity 13 of the nozzle unit 8. When carrying out a high-frequency generator source 29 is provided by a high-frequency effects on fluid flow in the cavity 13, thereby increasing energy efficiency. The hydraulic system must have a permanent gas separator gas outlet (air) from the system, and a device for stabilization of pressure, see., For example, block 43 with a reducer and safety valves in Figure 3.

If you have extra blade system 37 and / or the performance of the channel 16, directly to the supply liquid (without losing its circulation) to the input of the main blade impeller system, see FIG. 4, carried out partial discharge at the time of the drive shaft 9, which promotes energy efficiency and the reliability of the heat source.
