| 简介 |
The present invention relates to a heat exchanger. More specifically, the present invention relates to the heat exchanger made of an aluminum alloy and designed to enable a tube and a heat exchanging fin of the heat exchanger to have a potential difference. According to one aspect, the heat exchanger comprises : the tube where a refrigerant flows; the heat exchanging fin coupled to a surface of the tube; and a filler enabling the tube and the heat exchanging fin to be coupled. The tube is made of the aluminum alloy containing rare earth metals, and the heat exchanging fin and the filler is able to be made of the aluminum alloy containing silicon (Si), copper (Cu), and zinc (Zn).COPYRIGHT KIPO 2017 |
