<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, foaming failure and appearance change of a refrigerator with the foaming failure occur, and improvement of heat insulation performance is limited.SOLUTION: A first groove part 15 and a second groove part 16 provided in a vacuum heat insulation material are connected to each other, and the rear faces of the first groove part 15 and the 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> |
