摘　　要：星间激光通信终端因质量轻、体积小且对光学组件温度要求严苛,其热控设计具有一定挑战性。文章以固定式同轨终端为研究对象,全面综合考量平台因素与空间环境对终端的影响,开展热量传递分析和热控方案设计。基于同轨终端独特的结构特点,精心设计出灵活性较高的散热面,配合主动加热回路,显著提升了同轨终端在不同组网轨道的热控适配能力。地面及在轨验证表明,所设计的热控方案能够有效控制同轨星间激光通信终端光学系统在轨温度波动不超过±0.4℃。本研究为激光通信终端热控系统提供了一种简化的设计思路,可为后续相关终端热控设计提供参考。The lightweight nature,compactness,and stringent temperature requirements for optical components pose challenges to the thermal control design of inter-satellite laser communication terminals.A fixed co-orbital terminal was chosen as the research object,and a comprehensive thermal control design process was conducted from thermal transfer analysis to thermal control scheme,considering the influence of platform and space environment factors on the terminal.Based on the unique structural characteristics of the co-orbital terminal,a flexible radiator was designed,combined with active heating circuits,significantly enhancing the terminal’s thermal control adaptability across different orbital networks.Ground and on-orbit verification results indicate that the designed thermal control scheme ensures the on-orbit temperature fluctuation of the optical system of the co-orbital inter-satellite laser communication terminal to be within±0.4℃.This research provides a simplified design method for the thermal control system of laser communication terminals,which can be used as a reference for subsequent thermal control design of related terminals.
