The refrigerant flow paths of a heat exchanger (12) when the heat exchanger operates as a condenser form refrigerant flow paths in directions approaching one another while reciprocating between one end (S1) and the other end (S2), with a gas refrigerant flowing in from gas-side inflow ports (G1, G2) at two locations separated from each other in a second row (F2). At the one end (S1) the refrigerant flow paths from the gas-side inflow ports (G1, G2) at the two locations converge, connecting the refrigerant flow paths from the second row (F2) to a first row (F1) of heat transfer tubes (2), and form a flow path in a range from the same level as one of the gas-side inflow ports (G1) of the second row (F2) to the same level as the other gas-side inflow port (G2) of the second row (F2), while the first row (F1) reciprocates between the one end (S1) and the other end (S2), and this flow path reaches a liquid-side outflow port (L1). |
