Abstract
The present invention discloses a fin of heat exchanger comprising a straight segment; a substantially-circular arc segment having a radius of R; and a substantially-circular arc transition segment connected between the straight segment and the substantially-circular arc segment and having a radius of r, wherein R>r. According to the present invention, after being assembled and welded to the heat exchanger, the substantially-circular arc segment is relatively easy to deform, and the shapes of the straight segment and substantially-circular arc transition segment are substantially unchanged. Therefore, the deformation of the fin is regular and easy to control. The arranging density of the fin in the heat exchanger is uniform, and the shape of the fin can meet the design requirements. In addition, the shape stability and the heat transfer coefficient of the fin are high.
