DESCRIPTION OF THE INVENTION
The invention relates to a power system and can be used in heating systems and heating devices of wide application.
Known heat source is described in Russian Patent №2045715, cl. F 25 B 29/00, opubl.10.10.95. According to this invention a heat generator having a body with a cylindrical portion mounted fluid flow accelerator designed as a cyclone, which is connected to the end face of the cylindrical portion of the housing. At the base of the cylindrical portion opposite to the cyclone, the braking device is mounted.
Hydraulic fluid is supplied under pressure through a nozzle, placed tangentially to the cyclone body. Inside the housing there is a heat generator, strong swirl motion of the fluid. Thus, in accordance with the laws of thermodynamics, fluid mechanical energy is converted into heat energy.
The disadvantage of this is to reduce the heat generator heating the coolant intensity due to reduction of velocity of the fluid as it is away from the cyclone, and a hydrodynamic losses from the small diameter and long length of the overflow pipe. All this reduces the overall efficiency tepdogeneratora.
The closest analogue of the invention is the vortex heater (RF patent number 2,129,689, cl. 25 In the F 29/00, 27.04.99). Swirl heater comprises an inner cylindrical shell at one end of which fluid movement is set accelerator designed as a cyclone, which prednachnachen inlet for connection to the pump. Additional outer shell located around the interior. Between the shells is a spiral channel. In the inner shell at its end opposite the fluid flow accelerator are formed slits for supplying fluid from the inner shell in a helical path between the shells. The outlet is located in an extra (outer) shell from the fluid movement of the accelerator.
The disadvantage of this device is the presence of the spiral channels which allow not possible to develop high fluid velocity in the heat generator casing, as liquid is forced to move along spiral channels that create the very beginning of the braking effect of the flow. Because of this, when braking fluid at a slower speed generates less heat.
The technical problem of the invention - improving the efficiency of the heat source by creating a maximum velocity of the liquid inside the heat generator casing, effective braking and removal of heated fluid.
The problem is solved so that the heat source containing accelerator fluid motion in a cyclone inlet for supplying fluid under pressure, the housing of the two tubular shells - inner and outer, outlet connected to the outer shell according to the invention, the inner and the outer shell has symmetrically on either side of the cyclone and the cyclone distal end plugged, and the inner sheath remote from the perforated portion of the cyclone. The outer shell connected to a common outlet nozzle.
Performing the heat generator casing from two shells symmetrically on either side of the cyclone to create a maximum initial velocity in the cyclone, as ring jets diverge on both sides, without creating interference flow and the initial section of the inner shell of the heat generator casing without providing additional resistance.
Perforated inner shell portion is an effective device for braking the rotary motion of liquid with high velocity.
Muted ends of the inner and outer shells of the heat generator housing leads to the fact that spun at a high speed liquid flows completely through the perforated portion of the inner shell in the shell space, thus there is no brake fluid pressure shocks, and the kinetic energy of the fluid is converted into thermal energy.
The connection of the outer shells shell common outlet nozzle ensures the effective use of both halves of the heat generator casing, placed on either side of the cyclone.

Heat generator circuit is shown in FIG. The heat generator comprises a liquid accelerator movement 1, configured as a cyclone body comprising an outer shell 2 and the inner casing 3, a perforated portion of the inner shell 4, the plug housing 5, the inlet nozzle 6 with a nozzle 7 outlet pipe for exit of heated liquid. To the input port 6 is connected a pump (not shown) to the outlet pipe 7 are connected further heat consumption circuit and return fluid to the pump suction path (not shown). |
HEAT WORKS AS FOLLOWS
Working pump pressurized fluid is supplied through pipe 6 into the cyclone 1. In the cyclone 1 the inlet pipe terminates nozzle disposed tangentially to the wall of the cyclone body and the section is 5-10 times less than the pipe section 6. Naturally, the liquid flows from the nozzle with great moving speed and in a highly vortical state on the cylindrical wall of the cyclone and the heat generator casing inside the shell at an annular path.
At the same time due to internal friction in the liquid layer, and friction against the wall of the kinetic energy of the flow begins to turn into heat. On the perforated portion 4 inner casing 3 housing the heat generator due to the force of inertia, the fluid pressing against the wall of the annular fluid movement through radial perforation channels flows into the annulus between the inner and outer shells of the heat generator casing. This dramatically slowed down the movement of the annular liquid jets of liquid emerging through the perforation channel hit the outer wall of the shell 2.
Thus, the inner perforated shell portion kinetic energy of the fluid stream rapidly converted into heat energy. The heated fluid from the annulus is removed through the outlet 7. The heating of the liquid in the initial period and maintain the required temperature of the circulating fluid is produced in the small loop of the outlet 7 directly to the pump suction and delivery back to the inlet 6. Preheat the fluid to the desired temperature is sent to the contour of the heat consumption. If necessary, and to make optimal use of the heat generator body heat and heat-insulating pipes.
The heat source can work without personal pump. One pump of sufficient capacity may provide several heat generators placed at several sites the heat consumer. Furthermore, such a heat source can be operated through the selection of the liquid flow, for example, pressurized water, oil, etc.
The symmetrical arrangement of the heat generator casing of the inner and outer shells on both sides of the cyclone decreases the initial resistance at the liquid inlet to the heat generator allows to create the maximum speed of the annular swirling fluid flow that provides maximum isolation heat in the heat generator.
Perforation only on final length of the inner shell of the heat generator casing allows the use of heat from the internal friction in the vortical flow and effective braking without the entire flow of water hammer and the gradual removal of first heated stream bed near the wall.
Silencing distal end of the inner and outer shells causes the entire flow to pass through the perforated portion with a maximum heat release. In addition, friction of the end muffled additional amount of heat.
Common outlet for hot fluid from both halves of the heat generator casing provides a self-flow distribution inside heat generator casing.
Thus, the technical problem is achieved by the solution - increasing the efficiency of the heat generator by creating the maximum velocity of the fluid inside the shell of the heat generator and effective braking and selection of heated liquid.
