Abstract
A heat exchanger includes a plate fin, a first flat tube intersecting with the plate fin, and a second flat tube opposed to a flat tube lower surface of the first flat tube, the second flat tube being spaced from the first flat tube and arranged so as to intersect with the plate fin. A flat tube windward lateral surface of the first and second flat tubes is located on an inner side of a peripheral edge of the plate fin, which includes an elevated portion formed between the first and second flat tubes and is located between a first imaginary plane, connecting the flat tube windward lateral surface of the first and second flat tubes, and a second imaginary plane, connecting a center of the flat tube lower surface of the first flat tube and a center of the flat tube upper surface of the second flat tube.
