工作在真空罐内的平行光管的工作环境特点决定了其与空间光学遥感器相同的热设计原则,光管的结构形式对工作温度提出了严格要求。首先,确定光管结构表面的热控涂层和多层隔热材料的包覆方式;其次,光管热设计的关键是加热区设计,设计了两种加热方案,从可实施性和加热功耗大小对两种方案进行了比较;最后,对最终的热设计方案进行仿真分析。结果表明:平行光管光机结构的温度水平可控在19.3~20.8益,主镜温度为19.5益,满足设计要求,验证了热设计方案的可行性,可对其他同类型的地面光机结构的热设计提供借鉴。

The characteristics of the working environment in the vacuum chamber determine that the collimator should be designed with the same thermal principles as the space optical remote sensor. A stringent temperature requirement is needed for the collimator. Firstly, the variety of thermal control coating of its structural surface and the coated mode of the multi-layer insulation was determined. Secondly, two schemes of active heating were setup. They were compared from the feasibility of implementation and the value of heating power. Finally, the selected scheme was simulated. It is shown that the temperature level of the collimator is 19.3-20.8℃, and the temperature level of the primary mirror is 19.5℃. It meets the design requirements and the thermal design is feasible. These methods could be a reference for the thermal design of other ground optical instruments.
