THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM ELECTRONIC EQUIPMENT ELEMENTS Russian patent published in 2023 - IPC H05K7/20 H01L23/38 H01L23/467 

FIELD: electronics.

SUBSTANCE: invention can be used to provide the required temperature conditions for elements of electronic equipment (EE). In the main heat exchanger in the horizontal direction through cylindrical air ducts are made in a checkerboard pattern, which are tubes 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, whereas on the sides of the main heat exchanger opposite each other, two fan units are installed with the help of fasteners, which are powered by a source of electrical energy, so that they blow air through cylindrical air ducts. The main and additional sections of the TEB and the main heat exchanger form a structure having a recess in its central part, in which, with a thermal contact with the heat-absorbing junctions of the TEB main section, the EE heat-generating element is installed. A temperature sensor is installed in direct 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.

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 thermoelectronic battery (TEB) sections through the main heat exchanger due to the organization of forced air heat removal from it.
