To reduce a size of a physique, and to decrease a dead space in terms of mounting, in a laminated heat exchanger having a condensing part, an air-liquid separation part and an overcooling part.SOLUTION: A laminated heat exchanger in which a plurality of plate-shaped members 10 are laminated, and a refrigerant flow passage 11 in which a refrigerant flows, and a thermal medium flow passage 12 in which a thermal medium flows are alternately formed between a plurality of the plate-shaped members 10 comprises: a condensing part 2 for exchanging heat between an air-phase refrigerant and the thermal medium, and condensing the refrigerant; an air-liquid separation part for air-liquid separating the refrigerant which is condensed in the condensing part 2; and an overcooling part 4 for exchanging heat between a liquid-phase refrigerant which is air-liquid separated by the air-liquid separation part 3 and the thermal medium, and overcooling the refrigerant. The condensing part 2, the air-liquid separation part 3 and the overcooling part 4 are aligned in a lamination direction of the plate-shaped members 10, and the condensing part 2, the air-liquid separation part 3 and the overcooling part are formed of a part of the plate-shaped material 10 out of the laminated plate-shaped materials 10.SELECTED DRAWING: Figure 2

    【課題】凝縮部と、気液分離部と、過冷却部を備える積層型熱交換器において、体格の小型化を図るとともに、搭載上のデッドスペースを小さくする。【解決手段】複数の板状部材10が積層して接合され、複数の板状部材10同士の間に、冷媒が流れる冷媒流路11と、熱媒体が流れる熱媒体流路12とが交互に形成されている積層型熱交換器において、気相の冷媒と熱媒体とを熱交換させ、冷媒を凝縮させる凝縮部2と、凝縮部2で凝縮した冷媒を気液分離する気液分離部3と、気液分離部3で気液分離された液相の冷媒と熱媒体とを熱交換させ、冷媒を過冷却する過冷却部4とを設ける。凝縮部2、気液分離部3および過冷却部4は、板状部材10の積層方向に並んで設けられており、凝縮部2、気液分離部および過冷却部は、それぞれ積層された板状部材10のうち一部の板状部材10によって形成されている。【選択図】図2
