  ACC tube is a new type of tube that has got several national patents and declared for international pct PCT patent. This tube has an outer layer of antierust 3003 aluminum alloy and inner layer of oxygen-free copper. The copper-aluminum interface achieves metals bonding among atoms, popular saying: metallurgy bonding. ACC tube combines the excellent moment decalescence capability of copper with the excellent heat-sinking capability of aluminum. Thus, ACC tube owns good heat-transmit performance,which can be widely applied in air condictioner,refrigeration, dehumidifier and so on.The Heat-exchanger, adopting ACC tube, completely eradicates the electrochemisty decays between copper tube and aluminum of traditional Heat-exchanger, greatly reduces the recession of energy efficiency ratio, provides key material for making long-effect air conditioner, and saves more than 30% purchase cost for manufacturer.
