THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM RADIOELECTRONIC EQUIPMENT 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 equipment (REE). In the main heat exchanger, in the horizontal direction perpendicular to each other, two groups of through cylindrical air ducts are made, which are tubes made of highly thermally conductive material, each group is implemented in a checkerboard pattern, the upper ones are located in height below the level of the surface of the recess in which the REE element is located, at a distance of 2 mm from it, and on the sides of the main heat exchanger opposite each other with the help of fasteners, two pairs of fan units are installed, powered from a source of electrical energy, so that they blow air through two groups of through cylindrical air ducts, respectively. At the same time, the main section of the thermoelectric battery located in the centre and two additional sections of the thermoelectric battery located at the edges, with their heat-releasing junctions, are in thermal contact with the main heat exchanger, which is a hollow all-metal container filled with a melting working substance with a melting temperature in the range of 35-55°C; in the recess of the main section of the thermoelectric battery, there is a fuel element of the REE with a temperature sensor, 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 thermopile.

EFFECT: improving efficiency of heat removal from the REE element by increasing the intensity of heat removal from the heat-generating junctions of the sections of the thermoelectric battery through the main heat exchanger due to the organization of forced air heat removal.
