により放熱効果が更に増加する。The heat-insulating box of a refrigerator or the like according to the present invention has solved the above-mentioned problems, and the invention according to claim 1 disposes a condensing pipe in close contact with the inner surface of an exterior plate. In a heat insulating box body such as a refrigerator formed by injecting and foaming a foamed heat insulating material into a heat insulating layer, a bead which is in contact with or close to at least a part of a bending pattern of the condensation pipe is provided on the exterior plate. With this configuration, the bending pattern of the condensation pipe, which occurs when the thickness of the outer panel is reduced, is less likely to appear on the outer surface of the outer panel,
Also, even if the bending pattern of the condensation pipe appears on the outer surface of the outer plate, it appears near the bead, so the bead shape is clearly noticeable, and the bending pattern of the condensation pipe that appears on the outer surface of the outer plate is less noticeable In this state, the problem of impairing the external appearance can be solved, and the positioning of the condensing pipe at a predetermined position on the inner surface of the exterior plate becomes easy.
Moreover, by providing the beads, the surface area of the exterior plate increases, and the heat dissipation effect and the adhesive force with the heat insulating material increase.
When a bead is provided in contact with the condensing pipe, the number of contact portions of the condensing pipe with the exterior plate increases to two places, and the heat dissipation effect further increases due to the improvement in thermal conductivity.

The bending pattern of the condensation pipe, which occurs when the thickness of the condensation pipe is reduced, is less likely to appear on the outer surface of the outer panel, and even if the bending pattern of the condensation pipe appears on the outer surface of the outer panel,
Because it appears near the bead, the bead shape is clearly noticeable, so the bending pattern of the condensing pipe that appears on the outer surface of the outer plate becomes less noticeable, and the problem of impairing the appearance can be solved, and the outer surface of the condensing pipe can be solved. Positioning at the time of disposition at a predetermined position on the inner surface of the plate becomes easy. Moreover, by providing the beads, the surface area of the exterior plate increases, and the heat dissipation effect and the adhesive force with the heat insulating material increase.
When the bead is provided in contact with the condensing pipe, the number of contact portions of the condensing pipe with the exterior plate increases to two places, and the heat radiation effect due to the improvement in thermal conductivity further increases.
