THERMOELECTRIC DEVICE FOR HEAT REMOVAL FROM 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 equipment (REE), and can be used to provide the required temperature conditions. In the main heat exchanger in the horizontal direction through cylindrical air ducts are made in a checkerboard pattern, which are tubes of highly thermally conductive material, 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, whereas on the sides of the main heat exchanger opposite each other, two fan units are installed with the help of fasteners, which are powered by a source of electrical energy, so that they blow air through cylindrical air ducts. The device comprises the main section of the TEB located in the centre, and two additional sections of the TEB located at the edges, the main and additional sections of the TEB electrically connected in series consist of thermoelements identical in their geometric, electrical and thermal characteristics. The main and additional sections of the TEB with their heat-producing junctions are in thermal contact with the main heat exchanger filled with a consumable working substance in the range of 35-55°C, and have a recess in their central part, in which, with the provision of thermal contact with the heat-absorbing junctions of the main section of the TEB, the REE heat-generating element is installed. An additional heat exchanger filled with a working substance contacts the heat-absorbing junctions. A temperature sensor is installed in contact with the REE 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 by the intensity of heat removal from the heat-generating junctions of the thermoelectronic battery (TEB) sections through the main heat exchanger due to the organization of forced air heat removal from it.
