ABSTRACT:
A fin type heat exchanger includes a plurality of plate shaped fins disposed in spaced parallel relationship to define air channels therebetween for conducting an air flow from an air inlet side to an air exhaust side of each fin. A bent pipe extends through pipe holes formed in the fins for conducting a heat exchange fluid. Groups of slits are formed in each fin, whereby there is a first row of slit groups adjacent the air intake side, and a second row of slit groups adjacent the air exhaust side. There are more slits in the first row than in the second row. The slits in the first row have a width greater than the width of the slits disposed in the second row.
