Abstract: PROBLEM TO BE SOLVED: To improve the productivity of a fin by simplifying the shape of the fin while preventing the reduction in heat exchange capacity.
SOLUTION: A plurality of rise parts 2c are provided to be mutually symmetric on the upstream side and the downstream side of an air flow. According to this, in the fin molding process, mutually canceling directional bending forces continuously act on a thin plate-like fin material. Accordingly, since the deformation of the fin material to collect in one direction can be prevented at the time of forming the rise parts 2c, the dispersion of slit pieces 2d and the rise parts 2c can be minimized. Consequently, the shape of the fin 2 can be simplified to improve the productivity of the fin, while enhancing the heat transfer ratio between air and the fin 2 by the turbulence effect by the rise parts 2c to enhance the heat exchange efficiency.
