Abstract
PURPOSE: For improving heat insulation performance and preventing the formation of bypass and natural convection circuits, to construct a heat insulator of the heat- insulating tubes of which a part or the whole is covered with heat-insulating metallic material.
CONSTITUTION: A heat-insulating construction 41 is made of a molding fibrous heat-insulating material 6 and a multi-layer paper heat-insulating material 45 fitted ringed in the clearance between the heat insulating tube 44 made of the double cylinder 42 of a heat insulating material. The fibrous heat-insulating material 5 with high heat insulation performace covered with said heat insulating tubes 44 is prevented from subjecting to the sharp temperature and pressure change caused by working gas 2. Further, there arises a difficulty of forming bypass and natural convection circuits because said multi-layer heat-insulating material 45 is superior in strength and life.
