DEVICE FOR COOLING A HIGH TEMPERATURE SUPERCONDUCTOR

摘要

The invention relates to a device for cooling a high temperature superconductor, which device comprises a cryocooler using a first heat exchanging medium to cool a second heat exchanging medium to cryogenic temperatures, a heat exchanger having a first channel and a second channel in heat exchanging contact with each other, wherein the first heat exchanging medium flows through the first channel, wherein a third heat exchanging medium flows through the second channel and wherein the temperature of the third heat exchanging medium is lower than the temperature of the first heat exchanging medium. The invention further relates to a cryostat of said superconductor using magnetic suspension for spacing reflective layers of multi-layered thermal insulation.
