Heat exchange fin, heat exchanger and heat exchange equipment

The invention relates to the technical field of heat exchangers, and discloses a heat exchange fin, a heat exchanger and heat exchange equipment, the heat exchange fin is provided with a plurality of heat exchange pipe holes, the heat exchange pipe holes are arranged at intervals in the first direction, and the edge of at least one side, intersecting with the second direction, of the area between every two adjacent heat exchange pipe holes is provided with an inward concave structure; the distance between the lower edges of the heat exchange fins ranges from 0.4 D to 0.65 D, D represents the diameter of the heat exchange tube hole, and the distance between the lower edges is the distance between the edge of the heat exchange tube hole and the edge of each heat exchange fin; wherein the second direction intersects with the first direction. A plurality of heat exchange tube holes are formed in the heat exchange fins side by side in the first direction, and meanwhile, the edge of at least one side of the area be
