Abstract
The rotary type ultralow temperature refrigerant supply apparatus includes a refrigerant introduction pipe coupled to the super conductive rotor for supplying a liquid-phase ultralow temperature refrigerant cooled by the refrigeration system to the evaporator, a refrigerant withdrawal pipe disposed spaced apart from the refrigerant introduction pipe for withdrawing a gas-phase ultralow temperature refrigerant obtained through the evaporation of the liquid-phase refrigerant by the evaporator and guiding the withdrawn gas-phase ultralow temperature refrigerant to the refrigeration system, and a vacuum housing fixedly disposed outside the refrigerant introduction pipe and the refrigerant withdrawal pipe, the vacuum housing having a vacuum heat insulation space defined inside.
