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

FIELD: electronics.

SUBSTANCE: invention relates to electronics; it can be used for provision of required temperature modes of radio-electronic equipment (hereinafter – REE) elements. A thermoelectric device for removal of heat from REE elements contains a thermoelectric battery (hereinafter – TEB) electrically connected to an output of a temperature adjuster, an input of which is connected to a temperature sensor in contact with a heat-generating REE element located in a recess formed by TEB structure, the main heat exchanger in a thermal contact with heat-generating TEB junctions, and an additional heat exchanger. TEB is separated into main and two additional sections electrically connected in series and made of thermal elements identical in their geometrical, electrical, and thermal and physical characteristics. Moreover, the main TEB section is in the center of the main heat exchanger, and additional TEB sections are located along edges on protrusions of the main heat exchanger, an area of which corresponds to an area of additional TEB sections. The heat-generating REE element is placed in the formed recess to provide a thermal contact with heat-absorbing junctions of the main TEB section. The additional heat exchanger made in the form of a full-metal structure contacts with heat-absorbing junctions of additional TEB sections and the heat-generating REE element. At the same time, the main heat exchanger is made in the form of a hollow full-metal container filled with melting working substance with high melting heat and melting point in the range of 35-55°C.

EFFECT: increase in the manufacturability of a device due to the use of thermal elements identical in their geometrical, electrical, and thermal and physical characteristics, as well as provision of the maximum cooling coefficient, the maximum cooling capacity in the operation of TEB.
