Document Type and Number:
WIPO Patent Application WO/2022/113298
Kind Code:
A1
Abstract:
A heat exchanger (HE) comprises: a fin (F) that is configured so as to extend in a shortitudinal direction (D1) along an air flow direction (D0) and a longitudinal direction (D2) that intersects the air flow direction (D0); and a heat exchanger tube (P) that passes through the fin (F). A through hole (TH) is provided in the fin (F). The heat exchanger tube (P) is inserted into the through hole (TH). The fin (F) includes a flat portion (SP), and a first mountain portion (MP1) and a second mountain portion (MP2) configured so as to protrude from the flat portion (SP). The first mountain portion (MP1) is configured so as to be curved along the longitudinal direction (D2). The second mountain portion (MP2) has an extension portion (EP) that extends in the longitudinal direction (D2). The extension portion (EP) is disposed so as to overlap the center of the through hole (TH) in the shortitudinal direction (D1).
