Abstract

The invention provides a heat exchanger fin, a heat exchanger, an indoor unit and an air conditioner. The heat exchanger fin comprises a fin body, the fin body comprises an air outlet contour line onone side and an air inlet contour line on the other side, and the fin body is provided with a plurality of refrigerant pipe mounting holes. On the straight line where the curvature radius of the air outlet contour line of the fin body is located or on the 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 of the heat exchanger fin to the two ends. The inner diameters of the refrigerant pipe mounting holes are gradually reduced from the middle part of the heat exchanger fin to the two ends. According to the technical scheme, the utilization rate of the heat exchanger fin can be improved, the heat exchange efficiency is improved, the energy consumption is reduced, material waste can be reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger fin, a heat exchanger, an indoor unit and an air conditioner. Background technique [0002] At present, the heat exchanger fins commonly used in indoor unit heat exchangers are mostly rectangular with equal width or with some special-shaped structures at both ends of the rectangle, and the pipe flow paths on the heat exchanger fins are evenly arranged according to the law. However, the air sent by the fan of the indoor unit is generally non-uniform, which may easily cause excess air volume in some areas of the heat exchanger and waste of materials in some areas, resulting in low utilization of the heat exchanger and affecting the heat exchange efficiency of the air conditioner. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, an o...
