とがあつた。Conventional structure and its problems Conventionally, as shown in Fig. 1, a heat dissipation pipe c of a refrigeration cycle is inserted into a flange groove b formed in an outer box a, and is pressed into the flange groove b by a seal form d. and has a structure in which an inner box e is inserted. However, the heat dissipation pipe c generally meanders in its length direction to some extent, and the seal form d, which has elasticity, cannot correct this meandering, so the heat dissipation pipe c is indicated by a broken line in the figure. As shown, the flange groove b also meandered, significantly deteriorating the heat radiation efficiency of the heat radiation pipe c. Furthermore, when the heat dissipation pipe b is close to the inner box e side, heat leaks into the refrigerator, which becomes a cause of deterioration in the efficiency of the cooling system. Furthermore, it was not possible to regulate the insertion distance of the inner box e, which sometimes caused problems in finning with a foaming jig (not shown) for the heat insulating material f, for example.

This is a U-shaped flange formed at the opening of the flange.
Reference numeral 4 denotes a heat dissipation pipe that forms part of the cooling cycle and is housed in the flange groove 5. In order to improve the adhesion between the heat dissipation pipe 4 and the flange portion 3, the flange groove 5 has a two-stage shape, with the back side being a dedicated heat dissipation pipe groove 6, and the front side being a groove for inserting the flange 2a of the inner box 2. 7, and the heat dissipation pipe 4 is a flat tube.

１５はシールフオームである。 Reference numeral 8 denotes a spring having a substantially hairpin-shaped cross section, and after the heat dissipation pipe 4 is accommodated in the heat dissipation pipe dedicated groove 6, it is inserted and attached to the inner end 9 of the flange portion 3.
One free end of this spring 8 is folded back into a U-shape to form a heat dissipation pipe abutting part 11 and an inner box end face abutting part 1.
2 are formed, and locking portions 13 that engage with the flange step portions 5a are formed at many free ends. Further, the end portion 11 is connected to the heat dissipation pipe 4, and the contact portion 12
The flange end portion 14 of the inner box 2 is in contact with the flange end portion 14 of the inner box 2.
15 is a seal form.

る。 In this configuration, the flange end 14 presses the contact part 12 of the spring 8 due to the elasticity of the inner box 2 itself, and the heat dissipation pipe 4 contacts the end 11 of the spring 8, so the spring 8
Due to the synergistic elasticity of the inner box 2 and the inner box 2, the heat dissipation pipe 4 can be reliably pressed and brought into close contact with the heat dissipation pipe dedicated groove 6. Further, the insertion distance of the flange 2a of the inner box 2 is restricted by a spring 8.

精度を向上できる。Effects of the invention The present invention consists of a U-shaped flange formed at the opening of the outer box, a heat dissipation pipe housed in a flange groove formed by the flange, and a heat dissipation pipe located outside the heat dissipation pipe in the flange groove. an inner box into which the end face is inserted, and a spring with a substantially hairpin-shaped cross section that is attached to the end inside the flange portion, and the free end of the spring on the side located in the flange groove is folded back into a substantially U-shape. , one side of the two opposing sides of the U-shape is the contact part of the heat dissipation pipe, and the other is the contact part of the inner box end surface, so the heat dissipation pipe is stronger due to the synergistic effect of the elasticity of the spring and the elasticity of the inner box itself. Since the heat dissipation pipe can be press-fitted into the flange, the heat dissipation efficiency of the heat dissipation pipe can be greatly improved, and since the insertion distance of the inner box into the flange groove is also restricted, dimensional accuracy can be improved.
