HEAT EXCHANGER AND REFRIGERATION CYCLE APPARATUS INCLUDING THE SAME

Abstract: a heat exchanger includes: a plurality of flat heat transfer tubes each having an elongated cross-sectional shape, each including refrigerant flow passages therein, and arranged apart from and in parallel with each other; and corrugated fins each provided between associated adjacent ones of the flat heat transfer tubes. each of the corrugated fins has fin portions each having a plate shape, and is bent into a wave shape such that the fin portions are arranged alongside of each other in an axial direction of the flat heat transfer tubes. the fin portions include louvers. the louvers are made as different types of louvers to have different configurations, such that the different types of louvers are provided at respective selected sets of fin portions, to thereby cause different amounts of frost to be formed on the fin portions.
