FLEXIBLE ELECTRIC HEATER Russian patent published in 2017 - IPC H05B3/36 

FIELD: electricity.

SUBSTANCE: invention relates to flexible electric heaters creating the temperature of up to 150°C, which are used to maintain the desired temperature of the onboard equipment of space vehicles, structural elements of air, sea and land transport, temperature control in spacesuits, and for domestic use. A flexible electric heater comprises a resistive element disposed between two sheets of electrically insulating material, and conductor wires. Wherein the resistive element is made of metal or alloy and without kinks, and is secured on an additional sheet of electrically insulating material located between the two said sheets. Moreover, the sheets of insulating material are composed of one or more dissimilar flexible thermally and radiation resistant highly electrically insulating materials with low outgassing in vacuum, and have a flat or curved shape.

EFFECT: invention provides high uniformity of temperature on the electric heater area, high electrical strength of the insulation, the possibility to be mounted on curved surfaces, and high resistance to storage and operating factors.
