VACUUM INSULATION HOUSING

摘要

PROBLEM TO BE SOLVED: To provide a vacuum insulation housing which achieves optimization of a gas barrier structure by the use environmental temperature and use location and thereby guarantees long term vacuum and thermal insulation performance with an inexpensive structure.SOLUTION: A vacuum insulation housing comprises: a vacuum insulation body 32 in which a core member 39 is enclosed in a resin made gas barrier vessel 33 formed into a hollow shape and is sealed in a vacuum; an exterior box 30 disposed at a high temperature side and made of a gas barrier material; and an internal box 44 disposed at a lower temperature side. The vacuum insulation body 32 is disposed closely contacting with the exterior box 30.SELECTED DRAWING: Figure 2
