Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem wherein a conventional parallel flow heat exchanger has poor water drainage property during defrosting and freezes if heating operation is continued for a long time in winter at low temperatures. SOLUTION: The parallel flow type exterior heat exchanger for a heat pump is configured to comprise small louvers having a narrow width, not normal louvers, only at both ends of a corrugated fin in a portion protruding from a flat tube toward the upstream and downstream sides of an air flowing direction.
