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

FIELD: electrical engineering.

SUBSTANCE: thermoelectric device for removing heat from elements of radio electronic apparatus (REE), and can be used to provide the required temperature conditions of the REE elements. The purpose of the invention is achieved due to the fact that with the heat-absorbing junctions of the main section of the thermoelectric battery (TEB), an additional heat exchanger, made in the form of an evaporative heat sink, is in contact with the heat-absorbing junctions of additional sections of the TEB and the fuel element of the REE, while the main heat exchanger is made in the form of a hollow all-metal container filled with a consumable working substance with a melting point of 35-55°C. In this case, in the main heat exchanger in the vertical direction there are blind cylindrical holes arranged in a checkerboard pattern, having a depth equal to 3/4 of the height of the main heat exchanger in its centre, and on the lower surface a fan unit is installed with the help of fasteners, powered from a source of electrical energy and working to blow air into cylindrical holes.

EFFECT: increasing the efficiency of heat removal from the REE element by increasing the intensity of heat removal from the heat-generating junctions of the TEB sections through the main heat exchanger by organizing forced air heat removal from it is the technical result of the invention.
