This stacked heat exchanger is provided with a first heat exchanger unit (12) that exchanges heat between cooling water and a refrigerant. The first heat exchanger unit (12) includes: a plurality of first plate-shaped members (11) that are stacked together and joined; and a plurality of first refrigerant flow paths (121) and a plurality of cooling water flow paths (122) disposed between the plurality of first plate-shaped members (11). The plurality of first refrigerant flow paths (121) and the plurality of cooling water flow paths (122) are aligned in the direction of stacking of the plurality of first plate-shaped members (11). The stacked heat exchanger is further provided with a gas-liquid separation unit (30) that has a first top plate (18) disposed at the outermost side in the direction of stacking of the plurality of first plate-shaped members (11), a second top plate (19) joined to the first top plate (18), and a space between the first top plate (18) and second top plate (19), said gas-liquid separation unit separating the gas and liquid of the refrigerant flowing therewithin and storing the surplus refrigerant in a refrigeration cycle. As a result, the stacked heat exchanger provided with the gas-liquid separation unit that separates the gas and liquid of the refrigerant has greater body compactness and less installation dead space. |
