Abstract

The thermal control method of the non-attitude satellite, paste or spray the high-emissivity thermal control coating on the equipment in the star, fill the thermal conductive filler between the equipment installed on the partition and the installation surface, and spray the high-emissivity thermal control coating on the inner surface of the rest of the structure star Floor. The inner surface of the cabin board is covered with multi-layer heat insulation components to reduce the impact of drastic changes in heat flow outside the outer orbit of the star. Except for the installation surface of the instrument and equipment, the structural star module is pasted with third-order gallium arsenide solar cells. From the perspective of top-level system design, the present invention is based on the whole star isothermal design idea, fully utilizes the whole star structure heat storage, and utilizes solar cells as energy supply equipment and temperature control means at the same time, and adopts three-dimensional direction 3D isothermal heat pipe combination and integration The 3D isothermal device composed of a metal frame solves the problem of ensuring the temperature level of the entire satellite when there is no attitude control.

Description

technical field

[0001] The invention belongs to the field of thermal control of spacecraft, and relates to a thermal control method for the temperature level of satellite instruments and equipment. Background technique

[0002] In recent years, small satellites have attracted the attention of experts due to their high technology integration, low cost, and short development cycle, and have achieved rapid development. With the advancement of electronic integration technology and payload miniaturization technology, microsatellites smaller than small satellites will also emerge, which is also the inevitable product of the rapid development of microelectronics and micromechanical systems (MEMS) in the field of science and technology. The weight of a microsatellite is generally less than 100 kilograms, and the smallest is more than ten kilograms, or even several kilograms. The biggest advantage of micro-satellites is that they can be mass-produced and deployed in large numbers in...
