  • Fig. 6 is a cross-sectional view (arrow sectional view taken along line A-A in Fig. 5 ) of the connection portion.
  • connection pipe unit 20 With the thermally insulating material 60 as described above.
  • a small amount of water having condensed stays in a small space 70 ( Figs. 5 and 6 ) between the thermally insulating material 60 and the connection pipe unit 20.
  • the water having condensed and staying in the small space 70 covers surfaces of the aluminum pipes 31 and 41 and the copper pipes 32 and 42 in a continuous manner.
  • copper ions Cu2+ of the copper pipes 32 and 42 diffuse toward the aluminum pipes 31 and 41 against gravity through the water having condensed and staying, thereby causing electrolytic corrosion (galvanic corrosion) of aluminum or an aluminum alloy to occur.
  • Embodiment even when copper ions Cu2+ of the copper pipes 32 and 42, which are formed of copper or an copper alloy, diffuse against gravity toward the aluminum pipes 31 and 41 through the water having condensed and staying in the small space 70, a zinc diffusion layer is formed on the surface of each of the aluminum pipes 31 and 41 so that corrosion of the aluminum pipes 31 and 41 can be suppressed. By doing this, progress of corrosion of the aluminum pipes 31 and 41 formed of aluminum or an aluminum alloy can be suppressed, and accordingly, reliability of measures against leakage of the refrigerant can be improved.
  • the heat shrinkable tubes or coatings attached or applied to the connection portions 37 and 47 may be applied or attached entirely to ranges of the aluminum pipes 31 and 41, the ranges being covered by the thermally insulating material 60, in order to prevent water from adhering to the connection portions 37 and 47.
  • the heat shrinkable tubes are attached or coatings be applied to the aluminum pipes 31 and 41 while the aluminum pipes 31 and 41 are still connection pipes in an assembled state before being brazed to the heat transfer pipes 12 and 16 of the indoor heat exchanger 10.
  • the aluminum pipes 31 and 41 may be anodized or plated with metal such as zinc or manganese. Also in this case, it is desirable that the aluminum pipes 31 and 41 be anodized or plated while the aluminum pipe 31 and 41 are connection pipes in an assembled state before being brazed to the heat transfer pipes 12 and 16 of the indoor heat exchanger 10.
  • a clad material which is formed of a core material and a high corrosion-resistant aluminum alloy (for example, A7072) superposed on the core material, may be used for the aluminum pipes 31 and 41 as the material to which the anti-corrosion treatment is applied.
  • A7072 high corrosion-resistant aluminum alloy
  • an example of the heat exchanger according to the present invention is installed in the indoor unit 100.
  • the heat exchanger according to the present invention may be installed in the outdoor unit 101. That is, in above-described Embodiment, an example of the heat exchanger according to the present invention is used as the indoor heat exchanger 10. However, it is clear that the heat exchanger according to the present invention may be used as an outdoor heat exchanger.
  • an example of the cylindrical heat transfer pipes 12 and the flat heat transfer pipes 16 are used in the indoor heat exchanger 10.
  • the indoor heat exchanger 10 may use either the heat transfer pipes 12 or the heat transfer pipes 16.
  • an example of the heat exchanger includes fin-tube heat exchangers.
  • the present invention is applicable to a variety of heat exchangers. That is, the present invention can be implemented by connecting the gas pipe 30 and the liquid pipe 40, which have been described in Embodiment of the present invention, to a heat exchanger equipped with heat transfer pipes formed of aluminum or an aluminum alloy.
