The invention relates to devices for thermostatic control of electronic equipment installed on rotating objects.

The purpose of the invention is to expand the functionality when the housing is placed on a rotating platform.

Figure 1 shows the device, a general view; figure 2 - diagram of the device; Fig. 3 shows the evaporation zone of the heat pipe, a longitudinal section; figure 4 - section aa in fig.Z.

The device contains a cooled object 1, placed in the housing 2 of the radiator. The housing 2 and the antenna array 3 are mounted on the support 4. The cooling circuit 5 is located on the rotating platform 6.

The object 1 is installed in an airtight volume 7. The cold junction of the thermopile 8 is attached to the object I, and the hot junction of the thermopile 8 is attached to the evaporator zone 9 of the heat pipe through a layer of heat conductive paste through detachable connections. The pipelines 11 pass through the internal cavity of the evaporator zone 9. The pipelines 11 between the body 2 and the platform 6 are made flexible, and their length is adapted to the maximum positions of the body 2 in space.

The cooling circuit 5 comprises a series-installed compressor 12, an air condenser 13. a throttle device 14 and an evaporator 15. The evaporator 15 is of the brine type and is designed to cool the intermediate heat carrier. The circulation of the intermediate coolant is carried out by the pump 16.

The evaporation zone 9 is covered from the outside by thermal insulation 17 and secured by the heat-receiving surface 18 through the layer of heat-conducting paste 19 to the hot melt of the thermopile 8 by means of elastic detachable joints. On the inner surface of the heat-receiving surface 18, a profiled capillary-porous groove structure 20 is applied, oriented along the smaller side of the evaporation zone 9. A multi-layered arterial mesh 21 is laid in the center of the surface 18;

The heat-receiving surface 18 is connected by channels with a fluid collector 22 installed below its level. The volume of collection 22 is equal to the volume of refueling of the heat of the carrier minus the volume of structures 20 and 21.

Condenser zone 10 is finned and fixed at a fixed angle.

The device works as follows.

The internal cavity of the heat pipe is evacuated and filled with a liquid working fluid.

0 with the body in an amount necessary to completely wet the structures 20 and 21 and fill the collector 22. When the thermopile 8 is in operation, the object 1 becomes chilled, and heat is generated at the hot junction, which is transferred through the surface 18 of the liquid. The resulting steam passes into the condenser zone 10. The device operates in two modes: at an ambient temperature much higher than 0 ° C (40-50 ° C) and

0 below 0 ° С (minus 40 minus 50 ° С).

In the first mode, circuit 5 operates. A cooled coolant circulates through pipelines 11. Condensation of the vapor of the working fluid of the heat pipe

5 is carried out on the external surfaces of the pipelines 11. The high ambient air temperature (above the temperature of the intermediate heat transfer medium) does not permit the liquefaction of vapors in the condenser zone 10.

In the second mode, circuit 5 is turned off. The circulation of coolant through pipelines 11 is terminated. The temperature head in the condenser zone 10 allows

5 to liquefy the vapors of the working fluid.
