NoveL thermaL controL device for spatiaL fLexibLe mechanism

Abstract

The invention discLoses a noveL thermaL controL device for a spatiaL fLexibLe mechanism, which comprises a fiLm type temperature controL heating beLt, copper nickeL pLain conductive cLoths and a F46 fiLm siLver pLating secondary surface mirror. The fiLm type temperature controL heating beLt is adhered and wound on the fLexibLe mechanism through GD414C siLicon rubber; 6 Layers of copper nickeL pLain conductive cLoth are wound on the fiLm type temperature controL heating beLt; a Layer of F46 fiLm siLver pLating secondary surface mirror is wound on the surface of the copper nickeL pLain conductive cLoths. By utiLizing the copper nickeL pLain conductive cLoth and the F46 fiLm siLver pLating secondary surface mirror, the spatiaL fLexibLe mechanism is integraLLy covered, not onLy can the externaL heat fLow be prevented, but aLso the irradiation is resisted, meanwhiLe, the power of the temperature controL heating beLt can be effectiveLy reduced and the energy can be saved. Moreover, the fiLmtype temperature controL heating beLt, the copper nickeL pLain conductive cLoth and the F46 fiLm siLver pLating secondary surface mirror are fLexibLe, and can be appLied to spatiaL fLexibLe mechanismswith various structures, incLuding rotating cabLes and the Like.

Description

technical field [0001] The invention relates to thermal control products for space vehicles, in particular to a novel thermal control device for space flexible mechanisms. Background technique [0002] The thermal control measures of conventional satellite extravehicular space flexible mechanisms (such as extravehicular cables, flexible waveguides, etc.) are mainly to cover the outer surface with multi-layer heat insulation components. However, due to the rotation requirements of some external cables or movable flexible waveguides, a certain temperature needs to be maintained to meet the rotation requirements, and low temperature compensation must be performed. At this time, conventional measures cannot meet the thermal control requirements. Some flexible waveguides outside the cabin have high internal heat consumption, and the multi-layer heat insulation components cannot dissipate internal heat dissipation, and conventional thermal control measures cannot meet the thermal ...
