PROBLEM TO BE SOLVED: To improve durability of a heat exchange device, in the heat exchange device configured by stacking a plurality of plates.SOLUTION: A condenser portion 110 of a heat exchange device 100 is provided with a flow channel P in which a high-pressure refrigerant flows from opening portions formed on the plurality of plates, and an inner pipe 32 having an outer diameter smaller than a diameter of the opening portions, is disposed inside of he flow channel P. The inner pipe 32 is disposed so that the refrigerant flowing into the condenser portion 110 flows inside of the flow channel P and outside of the inner pipe 32, and the refrigerant passing through a liquid tank portion 120 flows inside of the inner pipe 32.SELECTED DRAWING: Figure 2
【課題】複数のプレートを積層して成る熱交換装置において、熱交換装置の耐久性の向上を図ること。【解決手段】熱交換装置100のコンデンサ部110には、複数のプレートに設けられた開口部により高圧の冷媒が流れる流路Pが形成され、流路Pの内側には、開口部の径よりも小さい外径を有する内管32が配置される。内管32は、流路Pの内側かつ内管32の外側にコンデンサ部110へ流入した冷媒が流れ、かつ、内管32の内側にリキッドタンク部120を通過した冷媒が流れるように配置される。【選択図】図2
