摘　　要：根据萤火一号(YH-1)火星探测器面临长期火星阴影环境特点,对探测器的长火影热控设计及深冷试验验证进行了研究。给出了YH-1火星探测器长火影热控自主控制流程,以及各阶段热控方案。改造现有真空环境模拟器,完成了我国第一个实现全包络20K超低温背景模拟的探测器级真空热试验。长火影试验结果表明:YH-1火星探测器热控设计能满足度过长火影的温度要求,各单机能在出火影后成功唤醒正常工作。According to the characteristic of the long-term Mars shadow facing by YH-1 Mars probe, the thermal control schemes and deep-cold test of YH-1 Mars probe were studied in this paper. The flowchart of the autonomous thermal control and control schemes of various phases for the probe during the long-term Mars shadow was given out. The first vacuum thermal test of the whole probe class which was the whole envelope under the simulation background at the temperature 20 K was carried out in China. The test results of the long-term Mars shadow showed that the thermal control of the probe met the temperature requirement to pass through the long term Mars shadow. The every device could be wake-up to operate normally after the Mars shadow passing.
