Abstract

A cooling device and method for a high-temperature superconducting motor of a hydrogen-powered aircraft based on a dual evaporation-condensation cycle is provided. The latent heat of vaporization of liquid hydrogen fuel in the hydrogen-powered aircraft is used as the cooling source of the superconducting motor. The internal evaporation-condensation cycle can meet the cooling requirements of the superconducting motor during normal operation, and the external evaporation-condensation cycle can be used as a supplement to the cooling capacity of the device when the internal evaporation-condensation cycle is damaged or cannot meet the requirements. The coupling of the two effectively increases the adaptability of the cooling device to complex environments. When the supply of the liquid hydrogen is interrupted for a short time, the liquid nitrogen absorbs the heat of the high-temperature superconducting motor and vaporizes, ensuring the continuous operation of the high-temperature superconducting motor in extreme environments.
