The invention relates to the field of heat, in particular, to the design of evaporators, which is one of the basic elements of heat transfer devices can be ispolzovat design of the evaporator, selected as a prototype, comprising a housing evaporation chamber and placed inside the capillary structure, which form the evaporation zone and the zone of the cavity power. The disadvantage of the design is the dependence of the efficiency of the evaporator temperature in the zone of the cavity power.

The aim of the invention is to improve the health of the evaporator by creating the possibility of regulating the temperature in the zone of the cavity power.

This goal is achieved by the fact that in the known construction of the evaporator, comprising a housing evaporation chamber and placed inside the capillary structure, which form the evaporation zone and the zone of the cavity power, installed thermoelectric battery having two surfaces of the junctions, which, depending on the current direction become or surfaces of the hot and cold junctions, or Vice versa. Moreover, one surface of junctions connected in thermal contact with the zone of evaporation evaporation chamber, and the other surface of junctions connected in thermal contact with the area of the cavity power.

Thermal contact with the cavity of the power supply can be performed on the outer surface of the casing in the zone of the cavity power.

Capella parts of the implementation of thermal contact.

For thermal contact can be used heat pipe. Comparative analysis of the prototype allows us to conclude that the claimed evaporator is characterized by the fact that you have thermoelectric battery, with the two surfaces of the junctions, and one surface of junctions connected in thermal contact with the evaporation zone, and the other surface of junctions connected in thermal contact with the area of the cavity power. Thermal contact of one surface junctions with an area of oral feeding can be performed on the outer surface of the casing in the zone of the cavity power; however, the capillary structure can be made connected to the inner surface of the housing in the zone of the cavity power stations performing thermal contact. For thermal contact can be used heat pipe.

In Fig. 1 shows the design of the evaporator of Fig. 2-6 private evaporator design: perform thermal contact one of the surfaces of the junctions of thermopile with a cavity power on the outer surface of the casing in the zone of the cavity power (Fig. 2-6); the execution of the capillary structure connected to the inner surface of the housing in the zone of the cavity power stations the field of thermal includes a housing 1 evaporation chamber and placed inside the capillary structure 2, which form the evaporation zone 3 and zone cavity power 4. In the zone of evaporation is the vaporization and removal of steam to the steam pipe 5, which is hydraulically connected to the evaporation zone. The area of the cavity power is used to supply the liquid coolant in the evaporation zone. Also shown is the liquid pipe 6, hydraulically connected with the area of the cavity power (Fig. 1-6). Installed thermoelectric battery 7, having at least two surfaces of the junctions 8 and 9, which, depending on the direction of the current in the battery become superficial hot and cold junctions, respectively, or Vice versa. Moreover, the surface junction 8 are connected in thermal contact 10 with the evaporation zone 3, and the surface junctions 9 is connected thermal contact 11 with the area of the cavity power 4. Thermal contact 11 can be performed on the external surface of the shell in the area of the cavity power (Fig. 2-6), and the capillary structure can be made connected to the inner surface of the housing in the zone of the cavity power stations performing thermal contact (Fig. 4,5 and 6). The quality of thermal contact can be used heat pipe 12 (Fig. 2 and 6). On the outer surface of the shell in the evaporation zone set t is relevant.

By passing an electric current thermoelectric battery so that the surface of the junctions 8 and 9 become, respectively, the surfaces of the hot and cold junctions, due to thermal contacts 10 and 11 in the zone of evaporation is the heat dissipation, and in the area of the cavity power cooling (1st mode). Due to the cooling liquid in the zone of the cavity of the supply elasticity of vapor decreases, and this leads to increase the amount of fluid flowing per unit time in the area of the cavity power on the liquid pipe 6. Thus, increasing the power of the capillary structure and as a consequence, improving the supply of liquid evaporation zone. Therefore, increases heat loss by evaporation, which leads to increase in heat from the element 13. Since the cooling capacity of thermoelectric battery depends on the current intensity, and the intensity of the processes of heat transfer in the zone of evaporation depends on the strength of the current.

By passing an electric current through thermoelectric battery in the opposite direction of the surface junctions 8 and 9 become, respectively, the surfaces of the hot and cold junctions (2nd mode). This leads to the heating zone of the cavity power and owenia liquid in the evaporation zone, which leads to the decrease in the intensity of the heat from the element 13 and to increase its temperature.

Moreover, the intensity of the heat sink will also depend on the current strength.

Thus, the intensity of the heat in the zone of evaporation depends on the direction of the electric current in thermoelectric battery and the current values.

When performing thermal contact one of the surfaces of the junctions of thermopile on the outer surface of the casing in the zone of the cavity power (Fig. 2-6) the inner surface in the implementation of this thermal contact is becoming an area of the heat flow at 1-Ohm operation. Heat can be transferred by means of transfer pair with its subsequent condensation (Fig. 2, 4 6) and optionally a thermal conductivity in the capillary structure (Fig. 6). The return condensate or runoff in the field of mass forces (Fig. 2), or capillary forces, which is carried out when performing capillary structure connected to the inner surface of the housing in the zone of the cavity power stations performing thermal contact (Fig. 4, - 6). The area of the cavity, the power may be cooled by direct cooling fluid, the TRANS is).

In the 2nd mode of the heating zone of the cavity power is carried out either by direct steam heating region (Fig. 2), or by evaporation and vapour transport with subsequent condensation (Fig. 4-6), together with the conductivity in the capillary structure (Fig. 6), or by directly heating the liquid and its subsequent transport in the evaporation zone (Fig. 3).

The use of thermopile having two surfaces of the junctions so that one surface of junctions connected in thermal contact with the evaporation zone and the other zone of the cavity power, improves the efficiency of the device, because it is possible to regulate the temperature in the zone of the cavity power, and hence the intensity of the heat in the evaporation zone by controlling the electric current in thermoelectric battery in magnitude and direction. Performing thermal contact one of the surfaces of the junctions of thermopile with an area of cavity power on the outer surface of the casing in the zone of the cavity power simplifies the manufacturing technology of the evaporator. Thus the performance capillary structure connected to the inner surface of the housing in the area polostiob orientations.

The use of heat pipe 12 to provide thermal contact significantly increases the efficiency of the device and makes possible the production of more technologically advanced (Fig. 2 and 6).
