摘要：
In order to improve the adaptability of spacecraft thermal control system, this paper investigates the thermal control scheme of the deployable radiator coupled with a liquid loop. The thermal environment changes of the radiator at different orbit altitudes are analyzed. The thermal control characteristics of the fixed radiator and the deployable radiator in different orbit environments are compared. The results show that as the deployment angle of the radiator changes, the space heat flux absorbed by the radiator also changes, which directly affects the heat dissipation capacity of the thermal control system. The deployable radiator can enhance its ability of heat dissipation. In engineering applications, based on the thermal control liquid loop, by adjusting the deployment angle of the deployable radiator, the thermal adaptability of the spacecraft can be effectively improved. © 2021, Editorial Dept. of JA.
