<p>PROBLEM TO BE SOLVED: To solve the problem that since a heat radiation pipe is covered with a vacuum heat insulation material provided by crossing a first groove with a second groove, even small irregularities in the vacuum heat insulation material inhibit fluidization of a foam heat insulation material such as urethane, and foaming failure and appearance change of a refrigerator with the foaming failure occur.SOLUTION: The rear faces of a first groove part 15 and a second groove part 16 are formed into a substantially plane surface. Consequently, the vacuum heat insulation material can be disposed even in the inside of a storage at a turning portion of a heat radiation pipe 14 without projecting the heat radiation pipe 14, heat insulation performance can be improved, and foaming failure and appearance change of a refrigerator with the foaming failure can be reduced without inhabiting fluidization of a foam heat insulation material injected into the wall of the refrigerator and subjected to foam formation.</p> |
