THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM REA ELEMENTS Russian patent published in 2024 - IPC H05K7/20 H01L23/38 H01L23/42 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used to provide the required temperature conditions of elements of electronic equipment (REA). Increasing the efficiency of heat removal from the REA element by increasing the intensity of heat removal from the heat-generating junctions of the sections of the thermoelectric battery (TEB) by means of the main heat exchanger due to the organization of forced air heat removal from it is a technical result of the invention, which is achieved by the fact that in the main heat exchanger in the vertical direction, non-through cylindrical holes in the corridor order having a depth equal to 3/4 of the height of the main heat exchanger in its center, while a fan unit powered by an electric power source is installed on the lower surface using fasteners, powered by blowing air into cylindrical holes. The main, additional sections of the TEB and the main heat exchanger form a structure having a recess in its central part, into which, in order to ensure thermal contact with the heat-absorbing junctions of the main section of the TEB, a heat-releasing element of the REA is installed, a temperature sensor is brought into contact with the heat-releasing 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 sections of the TAB. In accordance with the sensor readings and the temperature control set on the scale, the main and additional sections of the TEB automatically maintain the temperature of the REA fuel element in the specified range.

EFFECT: increasing the efficiency of heat removal from the REA element.
