Abstract (en)
[origin: EP4253895A1] A heat exchanger (HE) includes: a fin (F) extending in a widthwise direction (D1) along an air flow direction (D0) and extending in a longitudinal direction (D2) crossing the air flow direction (DO); and a heat transfer tube (P) passing through the fin (F). The fin (F) has a through hole (TH). The heat transfer tube (P) is inserted into the through hole (TH). Each fin (F) includes a planar portion (SP), and a first protruding portion (MP1) and a second protruding portion (MP2) protruding from the planar portion (SP). The first protruding portion (MP1) is curved along the longitudinal direction (D2). The second protruding portion (MP2) has an extending portion (EP) extending in the longitudinal direction (D2). The extending portion (EP) is located to overlap a center of the through hole (TH) in the widthwise direction (D1).
