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 electronic equipment (EE). 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 of highly heat-conducting material, each group being implemented in a corridor 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 of 2 mm from it, while on the sides of the main heat exchanger opposite each other, by means of fasteners, two pairs of fan units powered by an electrical energy source are installed, so that they blow air through two groups of through cylindrical holes, respectively. In addition, an additional heat exchanger also made in the form of an evaporative heat sink is in contact with the heat-absorbing junctions of the additional sections of the thermoelectric battery (TEB) and the EE heat-generating element. 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.
