Abstract

The present invention discloses a fin for a heat exchanger, the fin comprises a plurality of fin plates (10) which are adjacent to one another, each of the fin plates (10) is formed with louvers (20); and a connecting portion which connects adjacent fin plates at an end of the adjacent fin plates. The connecting portion comprises a middle curved section (31) and side curved sections (32) located on the sides of the middle curved section (31), and the curvature radius of the middle curved section (31) is larger than the curvature radius of the side curved sections (32). With the technical solution of the invention, since the contact area between the flat tubes and the fin increases, the fin efficiency is increased and thus the heat exchange performance of the heat exchanger is enhanced.
