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). Non-through cylindrical holes are made in the main heat exchanger in-line, having a depth equal to 3/4 of the height of the main heat exchanger in its center, while on the lower surface with the help of fasteners a fan unit is installed, powered by an electric power source, working to blow air into the cylindrical holes. The main and additional sections of the TEB and the main heat exchanger form a structure having a recess in its central part, in which, with a thermal contact with the heat-absorbing junctions of the TEB main section, the REA heat-generating element is installed. A temperature sensor is installed in direct contact with the REA heat-generating element, the output of which is electrically connected to the input of the temperature controller, the output of the latter is electrically connected to the main and additional sections of the TEB.

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