THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM RADIOELECTRONIC EQUIPMENT ELEMENTS Russian patent published in 2023 - IPC H05K7/20 H01L23/38 H01L23/42 

FIELD: electronics.

SUBSTANCE: providing the required temperature conditions for elements of radio electronic equipment (REE). Non-through cylindrical holes are made in the main heat exchanger in a checkerboard pattern, having a depth equal to 3/4 of the height of the main heat exchanger in its centre, 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. In addition, an additional heat exchanger made in the form of a hollow all-metal container filled with a melting substance with a high melting heat and a melting temperature in the range of 35-55°C is in contact with heat-absorbing junctions of the TEB sections. A temperature sensor is brought into direct contact with the REE 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 REE element by increasing the intensity of heat removal from the heat-generating junctions of the thermoelectric battery (TEB) through the main heat exchanger due to the organization of forced air heat removal from it.
