General thermal design structure of satellite deck

Abstract

The invention provides a universal satellite deck thermal design structure, and relates to the field of satellite thermal control design. The universal satellite deck thermal design structure comprises a KS-ZA white paint layer, a multi-layer heat insulation assembly, a heat pipe network, a black paint layer, an aluminum honeycomb deck and a rotating mechanism. The heat pipe network is connected to the aluminum honeycomb cabin plate, a black paint layer is sprayed on the inner surface of the aluminum honeycomb cabin plate, a KS-ZA white paint layer is sprayed on the outer surface of the aluminum honeycomb cabin plate, and the multi-layer heat insulation assembly is connected to the outer surface of the aluminum honeycomb cabin plate through a rotating mechanism; the rotating mechanism drives the multiple layers of heat insulation assemblies to be unfolded and folded on the surface of the KS-ZA white paint layer, and therefore the size of the heat dissipation face of the aluminum honeycomb cabin plate is adjusted. The rotating mechanism is used for adjusting the area of the outer surface, wrapped by the multi-layer heat insulation assembly, of the cabin plate to achieve the purpose of controlling the temperature of the cabin plate, so that the cabin plate adapts to space thermal environments under different postures and orbits, and commercialized batch production of the satellite cabin plate is facilitated through the universal satellite thermal design.

Description

technical field [0001] The invention relates to the field of satellite thermal control design, in particular to a generalized satellite cabin plate thermal design structure. In particular, for different missions such as orbits, attitudes and payloads, adapt to changes in the thermal environment caused by changes in missions, especially involving mass-produced satellite decks. Background technique [0002] With the development of aerospace commercialization, new requirements are put forward for satellite manufacturing cost and development cycle. Due to the special space environment, the external thermal environment of satellites with different orbits, attitudes and payloads is more severe, and the difficulty of thermal design increases.
