摘要： A fin and a bending type heat exchanger having the fin are provided. The bending type heat exchanger includes a first header pipe, a second header pipe, a flat pipe and the fin. The first header pipe and the second header pipe have bending sections. The fin extends generally in a wavy shape along a longitudinal direction and includes a main section and a connecting section, the main section and the connecting section are connected in series so as to make the connecting section form a wave crest and a wave trough, and the fin is divided into a first end portion, a second end portion, and a central portion between the first end portion and the second end portion along a transverse direction, in which the connecting section of the central portion, forming the wave crest and the wave trough, is connected with the flat pipe, and a gap exists between the connecting section, forming the wave crest and/or the wave trough, of at least one of the first end portion and the second end portion and the flat pipe within the bending section.
