(57) Abstract:

The device is designed for heating liquids and can be used in heat generation in the heating apparatus of different purposes. The device is based on the heat generated by cavitation in the liquid in a confined space and flowing through the source of cavitation, which is located in the piston moving in this volume, and the liquid remains almost stationary with respect to all walls, except the walls of the source of cavitation. The device improves the efficiency of energy conversion into heat by reducing the unproductive costs of viscous friction on the walls, as well as to simplify and reduce the cost of construction due to the rejection of the use of pumps. 2 C.p. f-crystals, 2 Il.

The invention relates to a power system and can be used in heating systems and hot water supply and heating apparatus of different purposes.

A device for heating the liquid, based on the effect of excess (relative energy) in the heat of cavitation in the liquid, in particular water, when exposed to alternating pressure [U.S. patent N 4,333,796, 1982, Flynn H. isaly cavitation, apparently, due to the exothermic reactions nuclear transmutation occurring in the substance, strongly compressed and heated by accumulation of microscopic cavitation bubbles (the conversion of energy into heat). A typical device of this type contains a volume of liquid in which ultrasonic pulsators (magnetostrictive or piezoelectric) are standing sound waves of high intensity. The disadvantage of this known device is relatively low economic efficiency of its use, which is associated, first, with what limited the possibility of increasing energy efficiency by optimizing the processes of energy release by regulating parameters bubbles, secondly, with relatively low efficiency, complexity, high cost and bulkiness powerful pulsators.

Closest to the claimed physical essence and the achieved result is adopted as a prototype known device for the implementation of heat dissipation in the fluid [RF patent N 2061195, 1995, Dushkin, A. L., Krasnov, Y. I., L. Larionov Century, roosters, C. L.], in which excite the flow of fluid in the closed hydraulic circuit with which, for example, you may perform multi-channel injector), and the source of cavitation create variable time pressure, which in liquid form the gas cushion, the volume of which varies with the piston, provided with a device for moving it to establish the self-oscillating mode. The disadvantage of this device is its relatively low efficiency, because, first, the device itself is quite expensive, even in mass production, because it is rather expensive powerful high-pressure pump, second, is the relatively low efficiency of conversion of electrical energy into thermal energy (according to the authors of this invention, up 121%), which, in particular, is associated with a significant (30-40%) non-productive losses of energy by converting electrical energy into mechanical energy of the fluid in the pump and in fluid flow through the channels of the device. These losses are largely due to viscous friction (molecular and turbulent), movement of the fluid relative to the walls.

The aim of the invention is to increase the economic efficiency of the device converting electrical energy the device for heating the liquid, containing, as a prototype, the motor, the excitation device of the fluid, the source of cavitation, located in the closed volume of fluid, the device control pressure and the heat exchanger, unlike the prototype, perform device excitation of the fluid is not in the form of a pump, and a piston which is mechanically connected with the motor, moving in a confined volume of liquid (for example, reciprocating motion in a cylindrical volume, or movement on a circle in the volume having the form of a body of rotation, and the motion of the fluid around the circumference prevented by using a valve system); in addition, source cavitation perform specified in the body of the piston, and the device pressure control is a device that will limit the maximum overpressure.

This allows to minimize unproductive energy losses due to viscous friction in the fluid motion relative to the wall, because instead of a stationary source cavitation and pump the fluid through the circuit using the source of cavitation, which move in a closed volume of liquid. Hydrodynamic parameters (differential pressure, flow and other) at the source of cavitation, which is necessary for its optimal is Yama, moreover, leakage of fluid when the piston between its walls and the walls of this volume is minimal, and almost all the liquid flows through the source cavitation.

This invention is illustrated by drawings, which depict two possible variants of the device.

In Fig. 1 shows a device that includes an engine 1, which by means of drive 2 (for example, containing the gearbox and crank mechanism), mechanically connected to the piston with a source of cavitation 3, which can move (e.g., reciprocating) in the housing 4 (e.g., having a cylindrical shape); the optimum pressure in the accumulation of bubbles (source cavitation) supported by the device limits the maximum gauge pressure of 5. The generated heat energy is directed to consumers through the walls of the enclosure through the heat exchanger 6.

In Fig. 2 shows another possible implementation of the device, which in this case contains a motor and a drive gear (not shown), the piston with the source of cavitation 3, mounted on the shaft, which can rotate in the housing 4, having the form of a body of rotation, the piston moves OCD is hidcote circumferentially along the closed volume is prevented by using a valve system 7. This implementation is somewhat more complex technically than described above, but it basically allows you to withstand a few more optimal continuous flow conditions in the source cavitation.

The technical result of the application of the invention is the increased efficiency of energy conversion into heat, simplifying and cheapening the construction of the device.

The increase is due to the fact that almost the entire volume of fluid (except fluid in the channels of the source of cavitation and in close proximity to them) rests or moves slowly enough relative to the walls. So it is, this device is almost free from unnecessary loss of energy associated with viscous turbulent friction in high-speed flow of liquid in contact with the walls. Simplify and reduce the cost of manufacture due to the fact that it, unlike the prototype, does not contain an expensive powerful high-pressure pump, comprising, generally, a large part of the cost structure in General.
