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

FIELD: electronics.

SUBSTANCE: providing the required temperature conditions for elements of radio electronic apparatus (REA). In the main heat exchanger, relative to the lower surface, recesses under the area where two additional sections of fuel and fuel units are placed, 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 from a source of electrical energy, while the main fan unit, powered by the same source of electrical energy, at using fastening devices, it is installed on the lower surface of the main heat exchanger, located between the recesses, equipped with blind cylindrical holes in a checkerboard pattern. The main and additional sections of the TEB sections, connected in series, consist of identical thermal elements, which are in thermal contact with the main and additional heat exchangers filled with a melting working substance, while the temperature controller is electrically connected to the main and additional sections of the TEB sections.

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 by organizing forced air heat removal from it.
