Spacecraft thermal management system based on loop heat pipe

The utility model provides a spacecraft heat management system based on a loop heat pipe. The spacecraft heat management system comprises an evaporator, a liquid storage device, a steam pipeline, a liquid pipeline, a cold plate, a heat exchanger, a cold side connecting pipe, a hot side connecting pipe, an axial channel heat pipe and a heat dissipation face. The beneficial effects of the utility model are that the thermal management system is completely decoupled from the design of the whole satellite, only the specification of the loop heat pipe spectrum with enough heat transfer capability needs to be selected during the design, the size of the heat dissipation surface and the pipeline layout are designed, and the design complexity and the development cost are greatly reduced; the general assembly of the thermal management system only needs to thermally couple a single machine and a cold plate, and the general assembly process is convenient and fast; the loop heat pipe has high heat and long-distance heat tr
