いる。An example of a structure in which a condenser pipe is disposed in a groove on the front surface of a conventional refrigerator will be described below with reference to the drawings in FIGS. 3 and 4. Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3 made of synthetic resin, and a foamed heat insulating material 4 filled between the boxes 2 and 3. Reference numeral 5 denotes a substantially U-shaped groove provided in the front flange portion 6 of the outer box 2, into which the condenser piping 7 and the front flange 8 of the inner box 3 are inserted. 9 is a sealing heat insulating material for preventing leakage of the foam heat insulating material 4. Reference numeral 10 is a thermally conductive filler for improving heat conduction between the U-shaped bottom surface 11 of the groove 5 and the side surface 12 of the outer box 2, and is filled before injecting the foam insulation material 4. The foamed heat insulating material 4 flows into the bottom surface 11 of the groove 5 and the side surface 12 of the outer box 2, preventing deterioration of heat conduction and promoting heat dissipation from the condenser pipe 7.

Since the heat insulating material 9 for sealing is in contact with the surface, the heat cannot be effectively conducted from the entire circumference of the condenser piping to the front flange 6 and side surface portion 12 of the outer box 2, so that a sufficient heat dissipation effect can be obtained. The problem was that it could not be done.
本発明は上記問題点に鑑み、凝縮器配管７の凹溝５の側
