Problems solved by technology
The advantage of passive thermal control is that it does not consume power and has high reliability. The disadvantage is that it cannot flexibly control the temperature level of the entire satellite. Passive thermal control cannot meet the requirements for satellites with high equipment temperature requirements.

The invention provides a controllable reciprocating thermal control mechanism which comprises a straight reciprocating pushing mechanism and multiple layers of thermal insulation assemblies. The straight reciprocating pushing mechanism and the multiple layers of thermal insulation assemblies are connected; and the straight reciprocating pushing mechanism drives the multiple layers of thermal insulation assemblies to move so as to form different-degree shielding on a back thermal dissipation surface area of a spacecraft, so that an effect on controlling a thermal dissipation surface area is achieved, and a thermal control effect is finally achieved. The controllable reciprocating thermal control mechanism provided by the invention has the beneficial effects that the straight reciprocating pushing mechanism drives the multiple layers of thermal insulation assemblies to move so as to form different-degree shielding on the back thermal dissipation surface area of the spacecraft, so that the effect on controlling the thermal dissipation surface area is achieved, the thermal control effect is finally achieved, a temperature level of the spacecraft can be actively and effectively controlled, and the mechanism is low in energy consumption, quick in response, simple in structure and low in cost.
Description
technical field [0001] The invention relates to a thermal control mechanism, in particular to a controllable reciprocating thermal control mechanism. Background technique [0002] Thermal control is a complex technology. Satellite thermal control is to reasonably organize the heat exchange inside and outside the entire satellite, so that the entire satellite equipment is within a better temperature range. Due to the harsh thermal environment in deep space, the long-term terrestrial shadow and solar radiation cause a large temperature difference across the star, so it is necessary to take necessary thermal control measures to provide a good thermal environment for the entire star. The thermal control measures currently adopted include passive thermal control measures and active thermal control measures. Passive thermal control mainly relies on the overall layout of the spacecraft, the selection of materials with different thermal properties, and the reasonable organization o...
