ABSTRACT:
A fin tube heat exchanger for use in an air conditioner includes a plurality of fin plates spaced at regular intervals, disposed in parallel with one another. A plurality of heat exchange tubes extend through the fin plates in a direction perpendicular to planes in which the fin plates lie. A plurality of raised strips formed in a lower row have a height lower than those on the highest row, which causes water drops to readily drop along the fin plate. A plurality of embossed projection parts may be formed instead of or in addition to the raised strips.
