摘要： A heat exchanger and an air conditioner including the same. The heat exchanger includes a plurality of heat transfer tubes formed in a flat shape and configured to allow a refrigerant to flow in a vertical direction therein. The heat transfer tube includes a gas refrigerant region including one end connected to a refrigerant inlet port and another end disposed above the refrigerant inlet port; a two-phase refrigerant region including one end connected to the other end of the gas refrigerant region and another end disposed below a refrigerant outlet port; and a liquid refrigerant region including one end connected to the other end of the two-phase refrigerant region and another end connected to the refrigerant outlet port.

摘要： A heat exchanger is provided. The heat exchanger includes a configuration in which a heat transfer tube having a flat shape passes through a plurality of fins, and capable of securing drainage performance of condensed water retained on a surface of the heat transfer tube while improving a heat transfer rate, and further capable of suppressing an increase in ventilation resistance. The heat exchanger includes a heat transfer tube formed in a flat shape, and a plurality of fins, and a refrigerant flowing inside the heat transfer tube exchanges heat with air flowing between the plurality of fins. The fin includes a heat transfer expansion surface including a peak portion and a valley portion provided along an air flow direction, and a drain structure provided to overlap the heat transfer expansion surface.
