摘要:A spatial cold-shield system with cryogenic phase change refrigeration was studied to decrease the surface temperature of spacecraft under 100 K and surface infrared intensity under 0.5 W/m2 within 30 minutes in space. A 3-D unit and systematic model were established to simulate the real structures and the variation regularities of the major parameters under different flying periods. A simplified unit model and a systematic model were established to simulate the heat-transfer and flow-field of cold shield in cryogenic, vacuum and micro-gravitational conditions. The unit and systematic experiments were carried out to study the cryogenic phase change refrigeration in cold shield on the ground. The results indicated the simulated and experimented parameters of cold-shield were consistent with the designing conditions of spacecraft. The systematic model could make the LN<sub>2</sub> touching the surface easily and causing the surface temperature distributed more uniformly. The cold-shield could meet the requirement of cryogenic infrared intensity by phase change refrigeration in space.
