Abstract
A heat exchanger comprising a header to supply a refrigerant to a tube through which the refrigerant flows; a heat exchange fin to be coupled to the surface of the tube; and a filler to couple the tube and the heat exchange fin. The header, the tube, the heat exchange fin, and the filler comprise an aluminum alloy, the heat exchange fin comprises a fin core layer and a fin clad layer formed on at least one surface of the fin core layer, the tube has a potential value that is higher than that of the fin core layer by 20 to 250 mV, and the fin core layer has a potential value 20 to 100 mV lower than that of the fin clad layer.
Claims15
A heat exchanger comprising:
- a header configured to supply a refrigerant to a tube through which the refrigerant flows;
- a heat exchange fin to be coupled to a surface of the tube;
- and
- a filler to couple the tube and the heat exchange fin,
- wherein the header, the tube, the heat exchange fin and the filler comprise an aluminum alloy,
- wherein a fin clad diffusion layer and a zinc diffusion layer are formed on at least one surface of the tube,
- wherein the tube has a potential value higher than that of a fin core layer by 20 to 250 mV,
- wherein the fin core layer has a potential value lower than that of the fin clad diffusion layer by 20 to 100 mV.
An air conditioner comprising
- a compressor;
- an indoor heat exchanger;
- an outdoor heat exchanger;
- and
- an expansion valve,
- wherein at least one of the indoor heat exchanger and the outdoor heat exchanger comprises:
- a header configured to supply a refrigerant to a tube through which the refrigerant flows;
- a heat exchange fin coupled to a surface of the tube;
- and
- a filler coupling the tube and the heat exchange fin,
- wherein the header, the tube, the heat exchange fin and the filler comprise an aluminum alloy,
- wherein a fin clad diffusion layer and a zinc diffusion layer are formed on at least one surface of the tube,
- wherein the tube has a potential value higher than that of a fin core layer by 20 to 250 mV,
- wherein the fin core layer has a potential value lower than that of the fin clad diffusion layer by 20 to 100 mV.
