  • This paper reviews the functions of telescope enclosures in brief and summarizes the universal principle of observatory site selection. Then, it introduces the structure types, working characteristics and environmental conditions of typical telescope enclosures at abroad. By taking an enclosure with an aperture of 3.67 m in the advanced electro-optical system as an example, the thermal control scheme for the enclosure is analyzed, and the golden rule and methods of thermal design of modern telescope enclosures are proposed in detail. Furthermore, several kinds of key factors to be taken into account in design are pointed out. Finally, the design and analysis method for telescope piers are also discussed.
