摘要： A fin tube heat exchanger is internally provided with a plurality of plate-shaped and regularly spaced fin members, a plurality of heat exchanger tubes inserted into through-holes defined in each fin member and a plurality of raised pieces formed in each fin member in a plurality of rows. The raised pieces in the same row are raised from a fin base in a direction opposite to the direction in which the raised pieces in adjacent rows are raised. The number of the raised pieces in each row is gradually increased as their row is located farther from a common center line of the through-holes. The raised pieces are integrally formed with and raised from the fin base between adjacent heat exchanger tubes so that two slits defined between the fin base and each raised piece may be open against the air flow.
