摘要
A plate fin heat exchanger 1 includes a corrugated fin 3 and tube plates 2. An intermediate portion 33 of the corrugated fin between crest and trough portion 31 and 32 thereof has a plurality of protruding ribs 34 protruding beyond a surface of the corrugated fin and arranged in a first direction. Surfaces of the crest and trough portions being in contact with the tube plates are configured as contact surfaces 310, 320 with no protruding rib. Gently sloping portions 341 are provided between the protruding ribs and the contact surfaces of the crest and trough portions to gradually protrude from the surface of the corrugated fin with increasing distance from the contact surfaces, and are continuous with the protruding ribs.
