Superconductive generator difference diathermanous shell

Abstract

The invention is designed for overcoming the heat penetration defect of the shell of CN 105429432 B patent (superconductive generator for short). Although an upper hatch cover (patent is applied separately) is provided for the 'superconductive generator' to prevent the gas volatilized from the refrigerant from escaping, the open casing is closed, the temperature of the refrigerant is very low, andthe temperature difference between the refrigerant and the environment is very large, so that the common material shell cannot prevent the excessive transmission of the environmental heat from entering the refrigerant cavity which leads to the ineffective volatilization of the refrigerant. In order to reduce the waste of the refrigerant, the upper part and the lower part of a refrigerant cavity need to keep a proper temperature difference, the upper part and the lower part of the shell are divided into a plurality of parts with different heat permeability, the heat permeability of the upper part (1) of the shell can be properly increased, and the heat permeability of the lower part (2) of the shell is as small as possible, so that the temperature of the upper part in the cabin is higher,and the temperature of the lower part is lower to facilitate improvement of the superconducting wheel rotation speed and the generator efficiency. Each part of the shell can be made of different low-temperature resistant materials such as foamed plastics, low-temperature resistant composite materials and low-temperature resistant alloy vacuum dewar, and is arranged at the corresponding portion ofthe shell according to the diathermanous property of the parts.

AI Technical Summary

Problems solved by technology

However, the temperature of the refrigerant is very low, and the temperature difference between the environment and the environment is very large. The use of ordinary materials for the casing cannot prevent excessive heat from the environment from entering the refrigerant chamber, which will lead to ineffective volatilization of the refrigerant and cause waste.
