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 elements of radio electronic apparatus (REA), and can be used to provide the required temperature conditions of the elements. Non-through cylindrical holes are made in the main heat exchanger in a checkerboard pattern, having a depth equal to 3 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 TEB sections and the main heat exchanger form a structure that has a recess in its central part in which the REA element is installed. The additional and main heat exchangers are filled with a melting working substance; a temperature sensor is in contact with the REA heat-generating element of the REA, 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 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 sections of the thermoelectric battery (TEB) through the main heat exchanger due to the organization of forced air heat removal from it.
