Claims

[Claims for Utility Model Registration] (1) A plurality of tubes 1 and corrugated fins 2 are stacked in an alternate arrangement, and both ends of each tube are connected to a pair of hollow headers 3 and 4, and The heat exchanger is provided with a partition plate 10 that partitions the inside of at least one header so that the heat exchange medium flows in a meandering manner through the flow path configured as shown in FIG. On the other hand, the partition plate 10 has a small diameter portion 1 having an outer circumferential shape that can be adapted to the inner circumferential surface of the header.
0a and a swollen large-diameter portion 10b whose peripheral end can fit into the notch, and which engages with the inner surface or inner edge of the notch 11 in the partition plate 10; 10c is provided, and when the outer circumferential surface of the small diameter portion 10a of the partition plate 10 is brought into contact with the inner circumferential surface of the header, the circumferential end of the large diameter portion 10b is adapted to the notch portion 11. A heat exchanger characterized in that the heat exchanger is fitted into the header and is integrally joined to the header with the retaining means 10c being engaged with the inner surface or inner edge of the notch 11. (2) The heat exchanger according to claim 1, wherein the retaining means 10c comprises a convex portion that is forcibly pushed into the cut portion 11 and engaged with the inner edge thereof. (3) The retaining means 10c rises obliquely from the side of the small diameter portion 10a toward the side of the large diameter portion 10b, and is elastically restored by being forced into the notch 11, so that its tip end is attached to the notch. 11. The heat exchanger according to claim 1, which comprises a cutting piece that engages the inner edge of the heat exchanger according to claim 1. (4) The heat exchanger according to claim 1, wherein the retaining means 10c is formed of fine irregularities that engage the inner surface of the cut portion 11 by frictional pressure.
