Abstract
PURPOSE: To improve baking exhaustion at heat-insulative multi-layer, by mounting heat transmission wire contained in heat-reistant synthetic resin between outer tube and vacuum heat-insulation layer.
CONSTITUTION: Absorbent containing tube 2 containing a absorbent such as active carbon which absorbes more gas under low temperature is located on the outer circumference of refrigerant tube 1 for flowing refrigerant such as cryogenic Herium gas, while heat transmission wire for performing baking exhaustion of the absorbent is provided in the container tube 2, and heat-insulative multiple layer 4 where evaporated metal film and spacer having low heat transmission are alternatively laminated is provided at the outside of container tube 2. Heat-resistant synthetic resin film 5 such as polyamid film containing heat transmission wire such as nichrom wire is further provided between the outer tube 6 and heat-insulative multiple layer 4. Consequently it is not cut down easily while baking exhaustion is performed sufficiently and the leakage of gas after cooling is reduced.
