ACTIVE FLEXIBLE-FLAT ELECTRIC HEATER Russian patent published in 2022 - IPC H05B3/36 

FIELD: space technology.

SUBSTANCE: invention relates to the field of space engineering and can be used in the manufacture of flexible, flat, flexibly flat electric heaters (EH) that maintain radio-electronic equipment and spacecraft components in a working state (in a given operating temperature range) when exposed to low temperatures of outer space by heating radio-electronic equipment, spacecraft components, i.e. heated objects (HO) to the values of operating temperatures by supplying power to the EH for a specified time. In the design of the EH of the active actuator of the electronic component key (for example, a transistor), controlling the supply of power to the resistive layer of the EH (performing switching), providing control of the thermal power of the EH, the discharge of additional heat flow to the heated surface, while the role of the cooling base (radiator) to ensure the temperature mode of operation of the electronic component key in accordance with the technical specifications performs the base of the EH, installed with glue on the HO.

EFFECT: invention makes it possible to significantly simplify the design of the pump control device, in addition, when placing the electronic component key in the EH, there is no need for power current-carrying wires from the pump control device to the EH, which increases the efficiency of the thermal control system (TCS), saves the heat dissipation budget of the spacecraft, the power budget and the mass budget of the spacecraft.
