| description | The invention provides a heat exchange fin, a heat exchanger and an air conditioner. The heat exchange fin comprises a first section, a second section, a third section and a fourth section, and a first bending part is formed at the joint of the first section and the second section; before bending, the distance between the bending center of the first bending part and the first end in the length direction is L3, the length of the heat exchange fin is L1, and L3/L1=3/5-4/5; the distance between the bending center of the first bending part and one side face of the heat exchange fin in the width direction is L4, the width of the heat exchange fin is L5, and L4/L5=1/3-1/2; and after bending, a bending included angle of the first section and the second section at the first bending part is alpha 1, and alpha 1 is equal to 140 degrees-170 degrees. According to the heat exchange fin, by changing the bending angle and the position of the bending center of the first bending part, the arrangement of a U-shaped pipe is inc |
