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

FIELD: electrical engineering.

SUBSTANCE: thermoelectric device for removing heat from elements of radio electronic apparatus (REA). Manufacturing the main heat exchanger in thermal contact with the heat-generating junctions of the TEB, and an additional heat exchanger in the form of an all-metal structure, the area of which corresponds to the area of the TEB, while in the main heat exchanger in the horizontal direction, perpendicular to each other, there are two groups of through cylindrical holes, each group being implemented in-line, the upper holes of which are located in height below the level of the surface of the recess in which the REA element is placed, at a distance of 2 mm from it, while 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, which blow air, respectively, through two groups of through cylindrical holes.

EFFECT: increasing the cooling efficiency of the REA element by increasing the intensity of heat removal from the heat-producing junctions of the thermoelectric battery (TEB) sections.
