激光通信器作为一种先进的光通信的设备，通信容量大，传输速度快，具有广泛的应用前景。其对设备温度均匀性和稳定性要求高来保证通信质量，且转动关节在两个方位上转动来更大范围地获取信号，转动关节裸露在外空间，都给热设计带来挑战。针对激光通信器的工作特性和外部空间环境规律，采用主动和被动热控方法开展热设计，对转动关节热设计、大功率密度光学器件散热技术、散热面和高精度控温设计方面进行了介绍。并根据热设计状态，设计了单机的热平衡试验，通过高低温热平衡试验对热设计方案进行验证。试验结果表明，设计方案合理可行，为后续转动高热流密度的载荷热设计提供借鉴思路。

Laser communication equipment, with large communication capacity and high-speed transmission, designed for advanced optical communication, has broad application prospects. Owing to ensure communication quality, high temperature stability and equality are required, and outside satellite parts are running in two dimensions to obtain signals in a wider range, bring challenge to thermal control. The design project was based on work characteristic of the equipment and the rule of outer space thermal environment, and a way to thermal control was proposed. Passive method and active method were carried for thermal design, and thermal design of running units, large power units cooling, radiators design, and precision temperature control design, four aspects were presented. According to the state of thermal design, a thermal balance experiment was investigated under low and hot cases, and the results prove the thermal design correct, and bring a way to thermal control for the equipment with high heat flux and running parts.
