Abstract:
An indoor heat exchanger reduces an increase in air flow resistance and enables easy discharge of condensed water. A first heat transfer fin and a second heat transfer fin each include a windward main portion formed with a notch that receives a first flat tube and a second flat tube, respectively, and a leeward communication portion located on a side opposite to an open end of the notch. In the first heat exchange portion and the second heat exchange portion, the plurality of first flat tubes and the plurality of second flat tubes in the rows are arranged in a width direction, and the first and second heat exchange portions each have a bent shape with an inner peripheral side on a windward side and an outer peripheral side on a leeward side.

Claim (Index 1):
An indoor heat exchanger comprising:\n a first heat exchange portion comprising a plurality of first flat tubes arranged in rows and a plurality of first heat transfer fins that intersect with the plurality of first flat tubes, wherein the first heat exchange portion exchanges heat between indoor air that flows in a width direction of the plurality of first flat tubes and refrigerant that flows through the plurality of first flat tubes; and a second heat exchange portion comprising a plurality of second flat tubes arranged in rows and a plurality of second heat transfer fins that intersect with the plurality of second flat tubes, wherein the second heat exchange portion exchanges heat between indoor air that flows in a width direction of the plurality of second flat tubes and refrigerant that flows through the plurality of second flat tubes, wherein the plurality of first heat transfer fins and the plurality of second heat transfer fins each comprise a windward main portion formed with a notch that receives the first flat tube and the second flat tube, respectively, and a leeward communication portion located on a side opposite to an open end of the notch, wherein in the first heat exchange portion and the second heat exchange portion, the plurality of first flat tubes and the plurality of second flat tubes in the rows are arranged in the width direction, and the first heat exchange portion and the second heat exchange portion each have a bent shape with an inner peripheral side on a windward side and an outer peripheral side on a leeward side, wherein the first heat exchange portion does not make contact with the second heat exchange portion, wherein a clearance of 2 mm or less is located between leeward edges of the plurality of first heat transfer fins of the first heat exchange portion and the windward main portions of the second heat transfer fins of the second heat exchange portion, and wherein the second flat tubes are positioned windward of windward edges of the plurality of second heat transfer fins by from 0 mm to 2 mm.
