DESCRIPTION OF THE INVENTION

The invention relates to heat generators cavitation type used for heating systems.

A method of producing heat due to cavitation, whereby fluid is pumped in a closed circulation passage through swirler, creating pressure fluctuations in the circuit, see. RF Patent 2061195, cl. 6 F 24 J 3/00 - analogue.

Devices that implement this method requires the use of technically complex devices and modes of creating vibrations in the circuit is not sufficiently well defined.

And a device is known in which the working parts of the pump - the centrifugal bladed wheels - on its output interact with a special fixed working body, which gives rise to pressure pulsations and cavitation. At the same time the working bodies are arranged in a common housing, and the entrance and exit of the working bodies reported circulation passage provided with a throttling element, see. Russian patent 2054604, cl. F 24 J 3/00 - prototype.

This heat generator has a complicated design, practically does not allow it effectively to small thermal capacity. Setting a fixed working body at the outlet of the movable operating element triggers the entire impeller pressure on a small area of ​​the fixed working body, which leads to increased wear.

The object of the present invention is a significant simplification of the design of the heat source and the technology of its production to a level that ensures the efficiency of its application to the drive motors of low and medium power, from about 1.5 to 15 kW, while increasing reliability, simplifying operation and maintenance conditions.

This object is achieved in that the working elements, at least one of which is connected to a drive motor, designed as oppositely arranged disks mounted with clearance between their working ends provided with surrounding interconnected grooves formed on the entire surface of the working ends. Thus for intensification of the formation and collapse of cavitation liquid flows in along the grooves and slots between the disks from the axis to the periphery of the groove on the ends of the interacting working discs formed obliquely to each other.

Additionally, to further intensify the process energy in the case of performing the channel between the disks with a flow area, increasing radius, and for reducing the consumption of energy to bring the discs and provide reusable of the formation and collapse of cavitation when moving fluid from the axis to the periphery of the disk by at least one of the disks are made at its end located through one or several holes of different radii that report the working channel between the disks with a housing cavity.

For these purposes the circulation passage throttling element is mounted directly on the inlet and / or outlet of inter working channel and configured with a variable orifice angularly movable disk rotation, and on the periphery of the disc at the exit of the working channel of inter an additional slit cavitator.

To simplify heating systems as a whole, accelerating its heating and ensuring forced circulation of fluid in the external consumers of heat (eg heat exchangers) by means of the same disk of workers in the housing bodies in the peripheral drives action area is located directly (bypass) and reverse (underwater) channels are connected to the heat exchangers. By circulation channel and can be connected to at least one heat consumer with an adjustable throttle temperature.

To increase the specific power of the actuator and discharge of axial thrust bearings, at least one actuator drive is provided with grooves at both its ends and is located between the working faces of the two other disc working elements.

For start-up and operation of the heat source after connecting it to the heating systems in the body of the heat generator from the non-working end of the disc is axially symmetrical separation chamber communicated with the atmosphere of the air discharge from the system and reducing the working fluid saturation of dissolved gas.

For the purpose of generating hot air flow of the heat generator casing can be provided with heat exchange ribs which may be implemented as a fan blade in kinematic connection with the drive motor housing.

FIG. 1 - 7 are examples of the described device and its working bodies.

In case 1, see FIG. 1, are fixed actuator disc 2, which is set oppositely rotating movable actuator disk 3 disposed with clearance the disc 1. As the radius of the gap It can be constant or variable. At the ends of the interacting discs 1 and 2 are adjacent to each other of the groove 5. Shaft 6 disk 3 is connected to a drive motor (not shown).

On the movable disk 3 through openings 7 arranged, for example, in the end disk staggered grooves 5 and reporting with an internal cavity 8 of the housing 1.

In the housing 1 in the peripheral zone of action of the working bodies 2 and 3 are set tangentially positioned forward and reverse channels, pipes 9 and 10, reported to the external heat exchangers 11.

From the end of the inoperative disk 3 in the housing 1 is formed axially symmetric separation chamber 12, in this embodiment, is separated from the holes 7 and the partition wall 13, vertical channel 14 communicated with the surge tank 15 heating system.

Embodiments of the grooves 5 on the end face of the disk shown in Figure 2. Disks 2 and 3 can have various shapes and orientations of the grooves at the working end or the same heat source and used in various combinations.

The most preferred form of grooves orientation when the grooves 5 and 5 'for interacting mountaineers working discs 2 and 3 are inclined to each other, see Fig. 3, and form an angle significantly greater than zero, which provides a network end clearance in the working chambers 16, 16 ', 16'' ... located at different radii and drives tows limited vortex generated at the edges of the grooves 5 and 5' with their relative motion.

The inlet and outlet of working bodies 2, 3 are reported through the circulation channel, in this case, passing through the cavity 8 (see FIG. 1) of the housing 1, a gap between the partition 13 and the disc 3. Throttling element formed here in the form of calibrated holes 17 in the central part of the disc 3 and the suction chamber 18 of working bodies.

HEAT WORKS AS FOLLOWS

After filling the working fluid heating systems, such as water, and the engine is started by rotating the disk 6 through the shaft 3 occurs between the peripheral water circulation outlet of working bodies 2 and 3 and their suction cavity 18. Simultaneously, due to rotation of fluid in the peripheral zone of the cavity 8 is circulated water through the cavity, the connectors 9, 10 and 11. in this heat exchanger the air is gradually catching chamber 12 is separated and removed in the tank 15 up.

Additional water circulation in the working channel between the discs 2 and 3 is carried out by the water flow through the channels 7 in the disk 3. In the relative motion of the grooves in the centrifugal force field intense vortices are formed on all edges of the network 16. The cavitation chambers of the cavity, which, moving on the working channel between the discs 2 and 3, periodically fall into the low and high pressure zone by changing the size of the camera itself, move the vortices in the plane of the disc through the variable resistance limiting their relatively movable edges of the grooves 5, 5 '. On the whole process and imposed high pressure pulsations resulting from the collapse of cavitation cavities, and also due to flow pulsations through the channels 7 and a gap between the discs. As a result, there is intense heat and heating of the working fluid in heating systems. The process of starting and stopping of the shaft 6, and as its rotational speed can be regulated by temperature working fluid in heating systems, and the heated room.

FIG. 4 shows an embodiment of a heat generator with a movable plate 3, both ends of which are made the working groove 5 and which is located between two fixed discs 19 and 19 ', heat generator has two heating circuits, one of which channels 9, 10 in communication with the external heat exchanger 11, and a second circulation circuit comprises a heat exchanger 11 'and a boiler (heat accumulator) 20 (hot water to the heat exchanger system with a choke 21 formed at an adjustable temperature in the boiler 20. in this case the temperature is lowered the throttle section 21 is reduced, leading to pressure reduction in the cavity 18 suction cavitation processes and intensification of heat and therefore to accelerate the heating of the boiler 20.

With increasing temperature, the saturated vapor pressure is slightly opened and the throttle 21 increases the pressure in the suction chamber 18, while increasing the fluid flow in the circulation circuit. The heat input to the heat exchanger 11 is regulated by a throttle 22, for example at room temperature. To further intensify the cavitation process is output working of inter channel discs 19 and 3 sequentially main throttling element 17 of the circulation channel is an additional throttling member 23, with a variable section according to the angle of rotation of the movable disk 3 (e.g., a row of windows disposed around the periphery of the element 23, is constructed as a cylindrical sleeve). This design ensures in the heat source pressure variability in the network of the working chambers 16, 16 ', 16' ', ... in the various sectors of the working channel of inter rotational angle drive and an intensification of heat release process.

Figure 5 shows an example of execution of the heat generator where the separation chamber 12 is formed by the shaft 6 and the shaft is provided with a labyrinth seal 24 and locking the seal 25. Instead of labyrinth seal may use impeller 26 at the divider 13 of the chamber 12. Openings 13 in the partition 7 improve impeller job centrifugal air separator. The use of dynamic seals of the type 24, 26 in conjunction with a parking seal ensures automatic removal of air from a working fluid with a simple structure of the heat generator.

In this embodiment, additional heat intensification process is achieved by periodically changing the flow cross section of the throttling element made in the form of calibrated holes 17 on the movable disc 3 overlapping the angle of rotation of its end washer 27 with passage windows. Position of the puck 27 relative to the openings 17 can be adjusted manually or automatically. Performing gap variable at an angle > 0 between the ends of discs contributes to the intensification of the process of cavitation collapse upon application of pressure pulsations.

Figure 6 shows an example of the heat source to heat the air by blowing heated ribs 28 of the housing 1 of the heat generator. In the illustrated embodiment, the rotating body 1 is rigidly connected with the shaft 6 and the housing edges are formed as fan blades, enabling the movement of heated air.

7 in the housing body 1, both working - 29 and 30 - are made rotating in different directions, for example, by means of two motors 31 and 32, which allows a wide range of heating capacity to regulate the heat generator. If you turn off one of the engines corresponding shaft braked braking device 33 or 34, for example, designed as a freewheel.

Additional pressure pulsations in the working channel of inter achieved here periodic connection and disconnection of holes 7 to the cavity 8 of the housing 1 by relative rotation of disks 29 and 30 relative to slots 35 in the end walls of the body 1 a chamber 8 in fluid communication with the cavity 18, the suction working bodies.

To speed up the process of collapse of cavitation in the gap between the discs on their way out is the ring slit additional cavitator, increasing the pressure before entering the working fluid from the working gap in the cells. 16, see Fig. 3 and the intensified cavitation processes in the damping chamber 8, while reducing the working pressure therein.

Described heat source has a simple design, technological, working bodies easily and inexpensively replaced during servicing and maintenance.

The heat source is easily adaptable for use in a variety of heating and hot water systems automatically ensures system start, has ample opportunity to pegulirovaniya temperature and intensify the process of excess energy.
