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 elements of radio-electronic equipment (hereinafter – REE). 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 heat contact with heat-generating soldered joints of TEB, 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 heat and physical characteristics, wherein the main TEB section is in the center of the main heat exchanger, and additional TEB sections are located on 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 heat contact with heat-absorbing soldered joints of the main TEB section. The additional heat exchanger made in the form of a hollow full-metal container filled with melting working substance with large melting heat and melting point in the range of 35-55°C contacts with heat-absorbing soldered joints of additional TEB sections and the heat-generating REE element. At the same time, the main heat exchanger is made in the form of an evaporative heat sink.

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