ABSTRACT:
A heat exchanger has groups of cutouts provided on tabular fin surfaces, projecting in the direction of arrangement of the fins. Each of the cutouts has two opposed openings in the main direction of air flow as well as two leg portions that not parallel with the main direction of air flow, the cutouts being formed on the tabular fin surfaces alternately on the front and rear sides with a fin base portion placed therebetween. The heat exchanger substantially reduces heat resistance between the air and the fin surfaces and ventilation resistance when the humidity is high, and excels in noise characteristics since the configuration of each cutout provided on the fin surface on the air inlet side of a cross flow fan is changed.
