空间太阳望远镜(Space Solar Telescope，SST)主光学望远镜(Main Optical Telescope，MOT)口径达1 m，以2.8’×1.5’有效视场对日成像，将获得0.1"~0.15"的图像。SST MOT对日观测时所接收到的热量超过千瓦，成为影响望远镜成像质量的主要热源和杂散光源。为此，文中首先探讨了大口径太阳望远镜热设计与消杂光设计的特殊关联。然后，针对主镜筒内消杂散光的内遮光罩结构提出了热兼容设计，确定了内遮光罩结构热-杂散光效应集成设计的目标与评价体系。借助热分析软件获取SST MOT因内遮光罩结构参数变化引起的系统温度的变化趋势，从热控角度对内遮光罩结构的设计提出了建议：内遮光罩结构的垂直高度不宜超过400 mm。探索的内遮光罩结构热-杂散光效应集成分析方法也可为其他太阳望远镜的综合优化提供参考。

The SST (Space Solar Telescope) is designed to obtain its diffraction limit quality with aperture over 1m. It observes the sun with a small view field of 2.8’í1.5’ to obtain its high spatial resolution imaging of 0 . 1"-0 . 15". SST observing the sun directly can receive huge heat flow more than 1 000 W that will lead to unacceptable thermal distortion of the optical components. The sunlight enters into the telescope, which is an intense source of both heat and stray light. Based on the special thermal effect and stray light in the solar telescope, a compatibility analysis of the thermal effect of inner-shield in SST was performed. The relationship between the thermal control design and scatting elimination plan on the inner-shield structures in SST was presented. The objective and method of the compatibility analysis were determined. With the thermal analysis software, the temperature fields were calculated for a series of heights of inner-shield structure. A design of the inner-shield structure was put forward in thermal control terms and the suggestion was put out synchronously, which restrained the inner-shield with the height less than 400 mm. The aims of the optimal design of the inner-shield structure of SST are reached. The thoughts and methods of the optimal analysis are also useful for similar optical telescopes designed for solar observation.
