Abstract
An air-cooled and ventilated heat exchanger includes a fin and a plurality of heat transfer tubes. The fin has a plate-shaped part and a plurality of protruding parts. The plate-shaped part is positioned so that a plate-thickness direction intersects an air-flow direction generated by ventilation, and the protruding parts protrude from the plate-shaped part in the plate-thickness direction. The heat-transfer tubes are-inserted into the fin so as to intersect the air-flow direction. The protruding parts have a first protruding part and a second protruding part. An inclination angle of the first protruding part with respect to the plate-shaped part is a first angle, an inclination angle of the second protruding part with respect to the plate-shaped part is a second angle, and the second angle is different from the first angle. The second protruding part is placed adjacent to the first protruding part.
