摘　　要：针对航天光模块必须满足抗辐射、重量轻、体积小和具有一定的力学强度等设计要求,通过传热理论分析,利用Ansys软件仿真光模块的温度分布,改进航天光模块的散热条件,并设计凸台结构直接让发热器件与金属外壳接触,使得航天光模块能够满足工作温度要求,最后指出策略性地选择发热器件的工作时间能够改善散热条件。The space optical module must meet the design requirements of radiation resistance, light weight, small volume, and certain mechanical strength. Through analyzing the theory of heat transfer, the temperature distribution of optical module is simulated by Ansys, and the heat dissipation condition of aerospace optical module is improved. Through the design of the convex structure, the heating devices directly contact with the metal shell, so that the module can meet the working temperature requirements. Finally this paper points out that the strategic choice of the heating device working time can improve the heat dissipation conditions.
