Abstract: 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.

Abstract: A heat exchanger includes a shell and a plurality of tubes. The shell includes a heat exchange region in which a second refrigerant is to be introduced into the shell, so that a heat exchange occurs between the second refrigerant and a first refrigerant which flows through the plurality of tubes. The shell includes an inlet region through which the first refrigerant is introduced into the shell, a reverse region into which the first refrigerant is introduced, after the first refrigerant passes through the heat exchange region, and an outlet region into which the first refrigerant is introduced, after the first refrigerant passes through the reverse region and the heat exchange region, the first refrigerant being discharged out of the shell from the outlet region. The shell includes partition plates to divide the heat exchange region, the inlet region, the reverse region, and the outlet region.

Abstract: 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.
