Title:
DUAL EVAPORATION-CONDENSATION CYCLE COOLING DEVICE AND METHOD FOR HIGH-TEMPERATURE SUPERCONDUCTING MOTOR OF HYDROGEN-POWERED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2023/246848
Kind Code:
A1
Abstract:
Disclosed in the present invention are a dual evaporation-condensation cycle cooling device and method for a high-temperature superconducting motor of a hydrogen-powered aircraft. The present invention uses vaporization latent heat in a liquid hydrogen fuel in a hydrogen-powered aircraft as a thermal sink for a superconducting motor, which avoids the problems of power consumption, weight and complexity caused by using a low-temperature cooling machine. An internal evaporation-condensation cycle can satisfy the cooling requirement during the regular operation of the superconducting motor, while an external evaporation-condensation cycle can be used as a supplement for the cooling capacity of the device when the internal evaporation condensation cycle is damaged or cannot satisfy the requirement, the two cycles being coupled to effectively enhance the adaptability of the cooling device to a complex environment. Once supply of liquid hydrogen is interrupted for a short time, liquid nitrogen absorbs the heat of the high-temperature superconducting motor and is vaporized, thereby ensuring continuous operation of the high-temperature superconducting motor in an extreme environment.
