摘要：
A cryogenic loop heat pipe (CLHP) is a promising thermal control device for spacecrafts. To realize active temperature control of low-temperature elements in spacecrafts with a CLHP, heat transfer performance tests are carried out on a CLHP prototype and theoretical analysis is carried out for the thermal control capability of the CLHP prototype themselves manifested in the tests, and structure improvements are made for the CLHP prototype. The improved CLHP exhibits a constant system temperature difference between the main evaporator and the condenser as the heat load increases from 0 to the maximum capacity, and the constant system temperature difference is controllable to some extent through adjusting the power applied to the cold reservoir, therefore the CLHP has the same temperature control capability as a capillary pump loop.
