Title:
VACUUM HEAT INSULATION MATERIAL AND REFRIGERATOR USING THE SAME
Document Type and Number:
Japanese Patent JP2020012523
Kind Code:
A
Abstract:
To provide a vacuum heat insulation material that facilitates a work for assembling an adsorbent which can reduce adsorption of water content or gas component to a core material and suppresses deterioration in surface property of an outer coat material and thermal insulation performance, and to provide a refrigerator.SOLUTION: A vacuum heat insulation material includes: a core material 51 made of a fiber assembly; an adsorbent 54 adsorbing a gas component of the core material; and an outer packaging material 53 having a gas barrier property for storing the core material 51. The core material 51 includes: a penetration part in which slits are continuously formed so as to penetrate the core material in a thickness direction; and a hollow-out part that is formed by hollowing out the inside in a thickness direction of a part surrounded by the penetration part. An adsorbent is stored in the hollow-out part.SELECTED DRAWING: Figure 4
