FIG. 5 shows a conventional example, and is a perspective view showing a part of a core portion formed by corrugated fins 1 and tubes 2. As can be seen from this figure, between the multiple tubes 2 whose cross sections are oval,
A corrugated fin 1 bent into a wave shape is fixed by brazing or the like. Arrows P and Q in FIG. 5 indicate the direction of air flow.

するという欠点を有していた。 FIG. 6 is a horizontal sectional view of the core portion shown in FIG. 5. Assuming that the depth of the corrugated fin 1 is A, the depth of the tube 2 is B, and the contact length between the tube 2 and the corrugated fin 1 is C, the dimensions are determined for the purpose of preventing damage to the tube and increasing the heat dissipation area. A is somewhat larger than dimension B, and dimension B is also somewhat larger than dimension C. Since such a corrugated fin 1 is made by bending a band-like thin plate into a wave shape, a piece K as shown in FIG. 6 exists. Due to the existence of this piece K, in conventional heat exchangers, the air flowing through the core is obstructed at the front of the core, as shown by arrow R in Figure 6, and as a result, pressure loss increases. It had drawbacks.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to enable air flowing through a core portion of a heat exchanger to pass through the core portion smoothly.

Next, examples of the present invention will be described. FIG. 1 is a perspective view showing this embodiment, and corresponds to FIG. 5. In the figure, reference numeral 1 indicates a corrugated fin bent in a wave-like manner, and reference numeral 2 indicates a tube having an oval cross section through which a heated exchange medium flows, and both are fixed by brazing or the like.

A notch 4 is formed from the front edge 31 of the joint 3 to the front edge 11 of the corrugated fin 1, and the tube 2 is joined to the fin by bending the fin in a wave shape, as shown in FIG. It is.

れるので何も流れを阻害されることはない。 FIG. 3 is a horizontal sectional view of the core portion. When air flows from the direction of arrow P in the figure, the air follows a path as shown by arrow R and flows through the core portion. In other words, the notch 4 is formed at a location corresponding to the conventional piece K, and since air flows through this notch 4, the flow is not obstructed in any way.

だけ小さい方が望ましい。 In this embodiment, the notch 4 is formed in a straight line from the front edge 31 of the joint part 3 to the front edge 11 of the corrugated fin 1, but it is not limited to a straight line and may be formed in a curve. Further, the shape of the notch portion 4 is not limited to the substantially triangular shape as in this embodiment, and various shapes are possible. However, when considering the heat dissipation area of the corrugated fin 1, it is desirable that the area of the notch portion 4 be as small as possible.
