HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE

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 (D0); and a heat transfer tube (P) passing through the fin (F). The fin (F) includes a planar portion (SP)...

More Information
Summary: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 (D0); and a heat transfer tube (P) passing through the fin (F). The fin (F) includes a planar portion (SP), and a plurality of first protruding portions (MP1) and a plurality of second protruding portions (MP2) that protrude from the planar portion (SP). The plurality of first protruding portions (MP1) include a first projection (C1) curved downward in the longitudinal direction (D2), and a second projection (C2) curved upward in the longitudinal direction (D2). Each of the plurality of second protruding portions (MP2) surrounds a corresponding one of the plurality of through holes (TH). A vertex of the first projection (C1) and a vertex of the second projection (C2) are located at the same position in the widthwise direction (D1).
