Title: HEAT EXCHANGER AND AIR CONDITIONER
Abstract:
Provided is a heat exchanger having improved water drainability. In this heat exchanger, first plate fins (12a) are disposed at first intervals from at least one heat transfer tube (11) in a second direction perpendicular to a first direction. Second plate fins (12b) are disposed at second intervals from the first plate fins (12a) in the second direction. The first plate fins (12a) and first corrugated fins (13a) are connected by a plurality of first connecting parts (24) disposed at third intervals in the first direction. The first plate fins (12a) and second corrugated fins (13b) are connected by a plurality of second connection parts (25) disposed at fourth intervals in the first direction. The third intervals and the fourth intervals are greater than the first intervals and the second intervals.
