传统的热控百叶窗在有外来辐射直射影响的情况下散热效果受到很大影响,热量可控范围缩小。本文提出了一种新型热控百叶窗设计,通过改善其结构使得航天器散热表面在有外来辐射入射的情况下仍能达到对外散热的效果。论文对该新型百叶窗的辐射散热和控制策略进行了研究,结果表明该新型热控百叶窗设计能够达到改善原有热控百叶窗面对外来辐射时的散热性能的要求。
The traditional heat-control blinds have a great influence on the heat dissipation effect under the direct influence of external radiation, and the heat controllable range is reduced. In this paper, a new type of thermal control blinds is proposed. By improving its structure, the cooling surface of the spacecraft can still achieve the effect of external heat dissipation under the condition of external radiation incident. The paper studies the radiant heat dissipation and control strategy of the new type of blinds. The results show that the design of the new type of thermal shutter can achieve the requirements of improving the thermal performance of the original thermal control blinds against external radiation.
