Abstract
Disclosed are a heat exchanger fin, a heat exchanger, an indoor unit and an air conditioner. The heat exchanger fin includes a fin body, and the fin body includes an air outlet contour line arranged on one side and an air inlet contour line arranged on the other side; refrigerant pipe mounting holes are provided in the fin body; and on a straight line where the curvature radius of the air outlet contour line of the fin body is located, or on a straight line where the curvature radius of the air inlet contour line of the fin body is located, the distance between the air inlet contour line and the air outlet contour line of the fin body is gradually reduced from the middle to two ends of the heat exchanger fin.
