对某空间光学遥感器进行了热分析和热设计。分析其外热流,并根据其工作模式与热控要求,遵循“被动热控为主,主动热控为辅”的热控制策略,阐述了空间光学遥感器的热设计方法。通过热分析软件进行了计算机仿真,验证了热设计的正确性,其研究方法及结果对各类空间光学遥感器的热分析和热设计有一定的指导和借鉴作用。 Thermal analysis and thermal design of a space optical remote sensor. According to its working mode and thermal control requirements, the thermal control strategy based on “passive thermal control and active thermal control as secondary” is analyzed, and the thermal design method of space optical remote sensor is expounded. The thermal simulation software was used to simulate and verify the correctness of the thermal design. The research methods and results have some guidance and reference for the thermal analysis and thermal design of various space optical remote sensors.
