Abstract
A heat exchanger includes a refrigerant flow path into which a gas refrigerant flows from two gas-side inlets in the second row, that are positioned off from each other. Refrigerant flow paths from the two gas-side inlets converge in the one end portion. The refrigerant flow path connects to a heat-transfer pipe in the first row from the second row. The refrigerant flow path includes a refrigerant flow path which is formed in a range from the same stage as one of the gas-side inlets of the second row to the same stage as the other of the gas-side inlets of the second row, while being arranged along both ways between the one end portion and the other end portion in the first row, and the refrigerant flow path extends to a liquid-side outlet.
