[0005] The utility model further provides that the bottom edge of the heat exchange fin body extends along an inclined straight line.
[0006] In summary, the utility model has the following beneficial effects:
[0007] 1. When the bottom edge of the heat exchange fin body is not inclined, both ends of the two water repellent grooves are used for drainage, and the water is evenly drained, achieving good drainage effect.
[0008] 2. When the bottom edge of the heat exchange fin body is inclined, one end of the two water repellent grooves at the low position is used for drainage, and the water is concentratedly drained, achieving convenient collection. BRIEF DESCRIPTION OF DRAWINGS
