Fin and heat exchanger having the same

摘要

The present invention discloses a fin (1) comprising straight segments (11), and substantially-circular arc segments (12) connected with the straight segments (11) in turn along a longitudinal direction such that the substantially-circular arc segments (12) form wave crests and wave troughs of the fin respectively, the fin (1) is divided in a lateral direction (C) into a first and second end portions (112,114) and an intermediate portion (113) therebetween, each substantially-circular arc segment (12) at least forming the wave troughs in the first end portion is separated from a substantially-circular arc segment (12) of a corresponding intermediate portion (113) via a longitudinal slot (111), and a top of each of the substantially-circular arc segments (12) at least forming the wave troughs in the first end portion (112) is formed with a lateral slot (110) such that each of the substantially-circular arc segments (12) at least forming the wave troughs in the first end portion (112) is divided into a first and second straight portions (12a,12b).
