PROBLEM TO BE SOLVED: To provide an intermediate heat exchanger allowing an engine room of a vehicle to be effectively utilized.SOLUTION: An intermediate heat exchanger 20 includes: a flat hollow casing 21 provided with a first refrigerant flowing passage 22 inside, and further provided with in its peripheral wall, a refrigerant inlet 23 and a refrigerant outlet 24 which are communicated with the first refrigerant flowing passage 22; and a refrigerant flowing pipe 25 which is disposed in the first refrigerant flowing passage 22 in the casing 21, the inside of which is used as a second refrigerant flowing passage, and which is communicated with the outside of the casing 21 at its both ends. The first refrigerant flowing passage 22 in the casing 21 is a low-pressure refrigerant flowing passage, the second refrigerant flowing passage 26 inside the refrigerant flowing pipe 25 is a high-pressure refrigerant flowing passage. The refrigerant inlet 23 of the casing 21 allows the low-pressure refrigerant to flow into the first refrigerant flowing passage 22, and the refrigerant outlet 24 allows the low-pressure refrigerant to flow out from the first refrigerant flowing passage 22. One end portion of the refrigerant flowing pipe 25 is used as an inlet-side end portion 28 allowing the high-pressure refrigerant to flow into the second refrigerant flowing passage 26, and the other end portion is used as an outlet-side end portion 29 allowing the high-pressure refrigerant to flow out. |
