Abstract

The invention relates to an airborne evaporation cycle refrigeration comprehensive heat management system and a method and application thereof and belongs to the airborne equipment cooling field. The airborne evaporation cycle refrigeration comprehensive heat management system comprises a high heat flow heating element spraying cooling cycle sub-system and an evaporation refrigeration cycle sub-system; and the airborne evaporation cycle refrigeration comprehensive heat management system further comprises a phase change heat exchanger (7) connected with the high heat flow heating element spraying cooling cycle sub-system and the evaporation refrigeration cycle sub-system, and a fuzzy PID control system (10). According to the system, by means of the fuzzy PID control system, the influences of heat inertia are considered, and the cold energy is fully utilized to perform cold storage for a phase change material; and by means of frequency conversion of a compressor, the purpose that one evaporation cycle refrigeration system is used to provide the cold energy for a refrigeration space and an airborne high heat flow heating element at the same is achieved, the system is integrated, the cold energy of the evaporation cycle refrigeration system is comprehensively managed, the heat load of the refrigeration space and the heat load of the airborne high heat flow element are reasonably matched, the weight of the system is greatly reduced, and the airborne equipment requirement is met.

Description

technical field [0001] The invention relates to an airborne evaporative cycle refrigeration comprehensive heat management system and its method and application, belonging to the field of airborne equipment cooling. Background technique [0002] For high-power electronic components, the traditional cooling technology can no longer meet the cooling requirements. The spray cooling technology based on phase-change thermal cooling has high heat flux cooling capacity, which can meet the cooling requirements of high-power electronic components such as laser cooling and high heat flux electronic equipment cooling. However, the cooling capacity of a certain volume of phase change material is limited. When the solid material is completely liquefied, additional cooling capacity is required to condense it into a solid state to realize the cold storage of the phase change heat exchanger; in order to comprehensively and efficiently utilize the onboard evaporation cycle Refrigeration syst...
