However, in the above-mentioned conventional structure, on one heat exchanger, the louvers of the flat fins (hereinafter referred to as "radiation fins") must be different in the upper part 104 of the heat exchanger and the lower part 105 of the heat exchanger. Various heat exchangers reduce the productivity of one heat exchanger. In addition, because the shape of the fin louvers is simple, the area of the fin cannot be enlarged, and the heat exchange rate of the fin cannot be sufficiently ensured. In addition, since the cut hole is slightly larger than the louver surface, the whistling sound generated when passing between the heat sinks is increased, and there is a problem that the noise becomes louder.

In addition, due to the fin-to-fin pitch, the change in the height of the louvers is limited, and it is difficult to achieve a height difference that can sufficiently generate air pressure loss.

For example, when the concave portion or/and convex portion on the flat fin of the upper heat exchanger close to the blower are designed to be larger than the concave portion or/and convex on the flat fin of the lower heat exchanger When the protruding amount of the part is large, the air pressure loss in the upper heat exchanger becomes larger compared with the lower heat exchanger, so the front air velocity of the heat exchanger can be adjusted between the upper heat exchanger and the lower heat exchanger. Homogenization can not only maintain the working efficiency of the heat exchanger, but also realize the uniformity of the front wind speed of the heat exchanger. In addition, unlike the conventional louver shape, there is no cutout hole slightly larger than the louver surface, so the whistling sound caused by air passing through the heat sink can be suppressed.
