<p>PROBLEM TO BE SOLVED: To provide a refrigerator which solves the problem occurring when drawing out a pipe end part of a heat radiation pipe, which has high heat insulating properties and which is high quality without appearance deformation and the like.SOLUTION: A refrigerator includes a heat radiation pipe 18 disposed on the inner side of an outer case of a heat insulation box body, and a vacuum heat insulation material 21 disposed on the in-box side of the heat radiation pipe. In the vacuum heat insulation material, the heat radiation pipe is disposed in a recessed groove 22b, and at a pipe end part 18T of the heat radiation pipe, two or more of turn parts 18T-1, 18T-2 are formed. Thereby, it can be suppressed that a refrigerator wall becomes thick by covering the heat radiation pipe with the vacuum heat insulation material, and at the same time, the turn parts provided at the end part of the heat radiation pipe become a buffer (deformation absorption) when pulling the heat radiation pipe at the pipe welding connection time. Thus, peeling of th vacuum heat insulation material attached to the outer case can be prevented, heat insulation performance of the vacuum heat insulation material can be favorably maintained, and also appearance deformation of the outer case and deterioration of heat radiation capacity from the heat radiation pipe can be prevented.</p> |
