Note (General): This report describes the thermal design of the space infrared telescope of JAXA/SPICA. This advanced astronomical mission features long observation with high sensitivity and spatial resolution. The excellent performance of telescope is realized by the primary mirror of 3.5 m diameter and optical instruments cooled to 4.5 K or below. Thus, the cryogenic telescope requires efficient cooling system consisting of efficient radiators and mechanical cryocoolers. First, the thermal design of cryogenic system is analyzed to estimate the mission feasibility. Secondly, the developed mechanical cryocoolers are described. The BBM of He-3-JT cryocooler for 1.7 K successfully reaches the required cooling capacity of 10 mW at 1.7 K in ground experiments.
