To provide a complex type heat exchanger capable of improving a performance coefficient of an applied refrigeration cycle device without causing complication of a cycle constitution.SOLUTION: A complex type heat exchanger includes a heat exchange part 800 formed by a plurality of plate-like members 81 being laminated and bonded to each other. The heat exchange part 800 includes a heat absorption evaporation part 70 and an internal heat exchanging part 60. A heat absorption refrigerant flow passage 24 is formed in the heat absorption evaporation part 70, a cooling refrigerant flow passage 200 is formed in a cooling evaporation part 20, and a high-pressure side refrigerant flow passage 14 and a low-pressure side refrigerant flow passage 26 are formed in the internal heat exchanging part 60. The heat absorption refrigerant flow passage 24 and the cooling refrigerant flow passage 200 are connected in parallel with each other. Furthermore, the complex type heat exchanger includes at least one of a high-pressure side refrigerant outlet port 61 for causing the refrigerant outflowing from the high-pressure side refrigerant flow passage 14 to outflow to the cooling refrigerant flow passage 200, and a low-pressure side refrigerant inlet port 62 for causing the refrigerant outflowing from the cooling refrigerant flow passage 200 to flow into the low-pressure side refrigerant flow passage 26.SELECTED DRAWING: Figure 2 【課題】サイクル構成の複雑化を招くことなく、適用された冷凍サイクル装置の成績係数を向上可能な複合型熱交換器を提供する。【解決手段】複数の板状部材８１が互いに積層されて接合されることによって形成される熱交換部８００を備え、熱交換部８００は吸熱用蒸発部７０および内部熱交換部６０を有しており、吸熱用蒸発部７０には吸熱用冷媒流路２４が形成されており、冷却用蒸発部２０には冷却用冷媒流路２００が形成されており、内部熱交換部６０には高圧側冷媒流路１４および低圧側冷媒流路２６が形成されており、吸熱用冷媒流路２４および冷却用冷媒流路２００は、互いに並列的に接続されており、さらに、高圧側冷媒流路１４から流出した冷媒を冷却用冷媒流路２００へ流出させる高圧側冷媒導出口６１、および冷却用冷媒流路２００から流出した冷媒を低圧側冷媒流路２６へ流入させる低圧側冷媒導入口６２の少なくとも一方を有する。【選択図】図２
