Abstract: Disclosed are an outdoor heat exchanger, in which the length of a passage of a refrigerant is varied depending on an operational mode. The outdoor heat exchanger is included in an air conditioner and configured to operate as a condenser in a cooling operation of the air conditioner and as an evaporator in a heating operation of the air conditioner. The outdoor heat exchanger includes, a plurality of plates, a plurality of first refrigerant tubes, a plurality of second refrigerant tubes, and a plurality of third refrigerant tubes. In the cooling operation, a condensed refrigerant flows in the plurality of first refrigerant tubes, the plurality of second refrigerant tubes, and the plurality of third refrigerant tubes. In the heating operation, an evaporated refrigerant flows in the plurality of first refrigerant tubes and the plurality of third refrigerant tubes, but does not flow in the plurality of second refrigerant tubes.
