THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM ELECTRONIC EQUIPMENT ELEMENTS Russian patent published in 2023 - IPC H05K7/20 H01L23/373 H01L23/38 H01L23/42 

FIELD: electronics.

SUBSTANCE: invention can be used to provide the required temperature conditions for elements of electronic equipment (EE). The main and additional sections of the TEB together with the main heat exchanger form a structure having a recess in its central part, in which the EE heat-generating element is installed, and contact with an additional heat exchanger made in the form of an evaporative heat sink. A temperature sensor is installed in contact with the EE 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. In the main heat exchanger in the horizontal direction, through cylindrical air ducts are made in a checkerboard pattern, which are tubes made of highly thermally conductive material, the upper of which are located in height below the level of the surface of the recess in which the EE element is located, at a distance of 2 mm from it. On the sides of the main heat exchanger, two fan units are installed opposite each other, which blow air through cylindrical air ducts.

EFFECT: increasing the efficiency of heat removal from the EE element by increasing the intensity of heat removal from the heat-generating junctions of the thermoelectric battery (TEB) sections through the main heat exchanger due to forced air heat removal from it, whereas the main heat exchanger is made in the form of a hollow all-metal container filled with a melting substance with a temperature melting range 35-55°С, with protrusions along the edges, the area of which corresponds to the area of additional sections of the TEB.
