MULTI-TRACK FLEXIBLE 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 working condition when exposed to low temperatures of outer space by heating radio-electronic equipment, that is, heated objects (HO), to operating temperatures by turning on the EH for a specified time. In a multi-track flexibly-flat EH, which contains a resistive element located between two sheets of electrical insulating material and equipped with current-carrying wires, as well as an additional sheet of electrical insulating material located between the two specified sheets, with a resistive element made of metal or alloy and without kinks, which is fixed on an additional sheet, moreover, sheets of electrical insulating material consist of one or several heterogeneous flexible heat-resistant radiation-resistant highly electrically insulating materials with low gas emission in vacuum and having a flat or curved shape, on an additional sheet of the base of the EH, the second and third resistive tracks of the EH are formed, each of which is equipped with current leads. Triple redundancy increases the reliability of a separate EH and thermoregulating system (TRS) as a whole by duplicating the main structural elements in one device, shortens the technological cycle of manufacturing TRS by installing one EH instead of three on an HO, expands the functionality of the EH by providing three-stage regulation of the EH heating power.

EFFECT: expansion of the range of solutions for maintaining spacecraft equipment.
