摘　　要：根据萤火一号(YH-1)火星探测器的热环境特点,对热控分系统设计进行了研究,分析了热控分系统技术难点,给出了方案设计,介绍了大功率单机散热、探测器多模式自主热控和长火影热控等设计。热平衡试验结果验证了热控设计的正确性。According to the characters of the thermal environment of YH-1 Mars probe, the design of thermal control subsystem was studied in this paper. The technology difficulty of the subsystem was analyzed. The thermal control scheme was given out, which included the radiating of the device unit with high power, multi-mode adoptive thermal control of the probe and thermal control during the long Mars shadow.
