PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material that improves flexibility of pipeline of a heat radiating pipe in a refrigerator or the like.SOLUTION: A vacuum heat insulation material 1 includes a core material 2 and an external coating material 3 comprising a laminate film coating the core material, and decompresses and seals the inside of the external coating material 3. At least two or more grooves 4 are provided on the surface of the vacuum heat insulation material 1. Since the grooves 4 are intersected to each other at one or more places, a heat radiating pipe 7 arranged along the grooves 4 can be aligned in a multi-direction, and flexibility of design for pipeline and heat radiation can be improved. Also, since the heat radiating pipe 7 is intersected or concentrated, a heat radiation amount is increased in the part where the heat radiating pipe is intersected or concentrated, to thereby adjust temperature. |
