THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM REA ELEMENTS Russian patent published in 2023 - IPC H05K7/20 H01L23/38 H01L23/467 

FIELD: electrical engineering.

SUBSTANCE: thermoelectric device for removing heat from radio electronic apparatus (REA), used to provide the required temperature conditions of REA elements. The main heat exchanger is made in the form of a hollow all-metal container, filled with a melting working substance, while in the main heat exchanger, relative to the lower surface, there are recesses under the area where two additional sections of the fuel and fuel unit are located, the height of which is 3/4 of the height of the main heat exchanger in its side part, in which, due to fastening devices, additional fan units are installed, powered by source of electrical energy, and the main fan unit, powered by the same source of electrical energy, is installed using fastening devices on the lower surface of the main heat exchanger, located between the recesses, which is equipped with blind cylindrical holes located in-line. The temperature regulator, in accordance with the readings of the operating temperature sensor, turns on and off, if necessary, the main and additional sections of the TEB cell and automatically maintains the temperature of the REA fuel element of the at a given range.

EFFECT: increasing the efficiency of heat removal from the REA element by increasing the intensity of heat removal from the heat-generating junctions of the thermoelectric battery (TEB) sections through the main heat exchanger by organizing forced air heat removal from it.
