HEAT EXCHANGER

摘要

A heat exchanger is provided to form rear slit parts of rear fins to be biased toward front tubes for destroying air flow boundary layers generating low speed areas behind the front tubes, thereby carrying out heat exchange behind the front tubes smoothly. A heat exchanger includes tubes aligned in front and rear lines on the basis of air flow direction, and mounted with fins. The fins are divided into front and rear fins(20a,20b) and have slit parts(30;32,34) formed of slits aligned in a plurality of lines. The slit parts formed to the rear fins are biased to front ends of the rear fins for removing low speed areas formed behind the front tubes.
