Except for the ends of the second heat exchange tubes T 2 , the second heat exchange tubes T 2 are straight tubes, with the ends of the second heat exchange tubes T 2 being bent and protruding outside a core body of the heat exchanger, so that the second heat exchange tubes T 2 can be connected to the corresponding headers M 2 . The ends of the second heat exchange tubes T 2 are not in contact with the fins 3 .
  • the set of fins 3 is arranged in a row.
  • the set of fins 3 is arranged in a row
  • the set of first heat exchange tubes T 1 is arranged in a row
  • the set of second heat exchange tubes T 2 is arranged in a row.
  • any suitable structure may be employed for the headers M 1 and M 2 .
  • a structure in which the headers are separate as shown in FIG. 23 a structure in which the headers are connected to each other as shown in FIGS. 24 and 26 ; and a structure in which the headers are formed using a single tube by means of a partition plate as shown in FIG. 25 .
  • the first heat exchange tubes T 1 and the second heat exchange tubes T 2 share the fins 3 , if one circuit of a dual-circuit air-conditioning system is closed, then a heat exchange region of the fins used for that circuit can be used for the other circuit, thereby increasing the heat exchange efficiency of the heat exchanger.
