ABSTRACT:
A fin tube heat exchanger includes a plurality of fin plates spaced at regular intervals in parallel with one another and adapted to allow air to flow therebetween, each fin plate having a plurality of through-holes in at least one row in a longitudinal direction of the fin plates, a plurality of refrigerant tubes inserted into the through-holes of the fin plates in a perpendicular direction and a plurality of raised strips formed in a plurality of rows in a direction perpendicular to an air flow. The raised strips in the same row are raised from a fin base in a direction opposite to the direction in which the raised strips in adjacent rows are raised. The fin base and each of the raised strips define therebetween two openings open against the air flow. Rising portions on the refrigerant tube side of the raised strips in one row near to a center line of the through-holes are formed along a circular arc which has an identical center with the refrigerant tube. Rising portions on the refrigerant tube side of the raised strips in another row near to a longitudinal fin edge are formed along an outer tangential line of the circular arc. The number of the raised strips in another row near to the longitudinal fin edge is more than the number of the raised strips in one row near to the center line of the through-holes.
