The refrigeration device solves the difficult problems of valid storage of refrigerant during the space dynamic refrigeration of variable pressure, temperature and flow, improves the efficiency of space heat transmission, increases the efficiency of space refrigeration with phase change, realizes the relative stability of space refrigeration, and realizes the effective control of temperature on the surface of the space cold shielding system.

Description

technical field [0001] The invention relates to the layered animal liquid refrigeration technology in the space cold shielding phase change refrigeration system, and is especially suitable for the surface temperature control technology in the space cold shielding system, specifically, it is an indispensable part of the phase change refrigeration system in the high vacuum microgravity environment. Disclosed is a layered liquid storage refrigeration device for a space cold shielding system. Background technique [0002] Since the aircraft has complex aerodynamic heat transfer conditions during start-up and stable flight, the low-temperature fluid in the cold screen is in a state of intense phase change and multi-phase flow accompanied by drastic changes in pressure and temperature. How to keep the liquid relatively stable , vapor-liquid separation, effective discharge of steam, improvement of surface heat transfer efficiency, reduction of cold steam flow resistance, and preven...
