SOLUTION: This heat exchanger for a car air conditioner is provided with a refrigerant circuit comprising a compressor (electric compressor) 10. The refrigerant flowing in the refrigerant circuit, the radiator water and the cooling air can exchange the heat to each other. A double pipe 51 composed of an inner passage (inner pipe 52) and an outer passage (between the inner pipe 52 and an outer pipe 53), is mounted.
