PROBLEM TO BE SOLVED: To provide a heat exchanger having superior gas-liquid separation effect and capable of preventing waste of space, when it is disposed in an engine room. SOLUTION: This heat exchanger 1 comprises a pair of tanks 2, 3, a heat exchange tube 4 and a fin 5. Both tanks 2, 3 are respectively divided into two headers 15, 17, 16, 18 by partitioning members 11, 12, to dispose a condensing portion 13 and a supercooling portion 14. A liquid-receiving portion mounting member 7 is fixed to the first tank 2, and two liquid-receiving tubes 8, 9 extending in the vertical direction are fixed to the liquid-receiving portion mounting member 7. The liquid-receiving portion mounting member 7 is provided with a first flow channel 27, communicating the header 15 at a first tank 2 side of the condensing portion and the refrigerant inflow-side liquid-receiving tube 7, and a second flow channel 28 communicating the header 17 at the first tank 2 side of the supercooling portion 14 and the refrigerant outflow-side liquid-receiving tube 9. Both the liquid-receiving tubes 8, 9 are made communicating with each other. COPYRIGHT: (C)2009,JPO&INPIT
