ABSTRACT:
A fin tube heat exchanger includes a plurality of fin plates disposed in parallel with one another, spaced at regular intervals and adapted to allow air to flow therebetween, and a plurality of refrigerant tubes disposed in at least two rows, inserted into the fin plates in a perpendicular direction and being adapted to allow a fluid medium to pass therein. Each of the fin plates has a plurality of raised strips which extend in a direction perpendicular to a direction of air flow. A plurality of normal raised strips are formed on both sides of the fin plates in at least one row on an air flow outlet side. A plurality of low raised strips or embossings are formed on at least one side of the fin plates in other rows. The height of the low raised strips or embossings in the other rows are lower than the height of the normal raised strips in the at least one row.
