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). A temperature sensor is installed on 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, two groups of through cylindrical air ducts are made perpendicular to each other, which are tubes made of a highly thermally conductive material, each group being implemented in a hall order, 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 2 mm from it. On the sides of the main heat exchanger, opposite each other, by means of fasteners, two pairs of fan units are installed, powered from a source of electrical energy, which provide air blowing, respectively, through two groups of through cylindrical holes.

EFFECT: improving the efficiency of heat removal from the electronic equipment element by increasing the intensity of heat removal from the heat-generating junctions of the sections of the thermoelectronic battery (TEB) through the main heat exchanger due to forced air heat removal from it and an additional heat exchanger in the form of a hollow all-metal container filled with consumable substance with a melting point in the range of 35-55° C, whereas 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 the EE heat-generating element is located.
