EXTREME LOW-TEMPERATURE CONTAINER

摘要

PURPOSE:To reduce the heat intrusion by mechanically supporting an extreme low temperature tank by the CRRP tension rods which are applied with tension. CONSTITUTION:An extreme low temperature tank 2 is mechanically supported by the tension rods 7 made of CFRP which are applied with tension. The tension rod 7 is laid at the position where the distance can be provided as long as possible in a vacuum heat insulating part 6. Since CFRP possesses high strength, with such constitution, the thickness of the tension rod can be reduced sufficiently for supporting the load, and the heat transfer coefficient can be reduced, and heat intrusion can be reduced.
