The new copper-aluminum composite pipe utilizes the inner layer of copper to absorb heat with the refrigerant, and the outer layer of aluminum serves as a heat-dissipating purpose, and successfully realizes metallurgical bonding between copper and aluminum by using its own patented technology. The structure of the composite pipe is mainly a 3003 aluminum alloy pipe with a uniform composite weight ratio of about 68% on the outer surface of the T2 copper pipe. The composite tube has all inter-atomic metal bond bonds on the copper-aluminum joint surface, which perfectly combines the advantages of the two metals, and has strong anti-leakage ability and anti-vibration fatigue damage strength.
According to Tian Fusheng, chief engineer of Jiangsu Xingrong High-tech Co., Ltd., each ton of copper-aluminum composite pipe can save 850 kg of copper, and each air conditioner can reduce the cost by about 120-150 yuan. In addition, after the copper-aluminum composite pipe is used in the condenser and evaporator of the air conditioner, there is no electrochemical corrosion between the pipe and the aluminum fin of the air conditioner, and the long-term use does not reduce the cooling (heating) effect of the air conditioner, and at the same time improves the air conditioning. Energy efficiency ratio. Tested and tested by Guangdong Galanz Air Conditioner Co., Ltd., the copper-aluminum composite internally threaded pipe has an energy efficiency ratio of 5% higher than that of a single copper internally threaded pipe. According to this ratio, according to the existing air conditioning capacity in the country, it can save more than 2 billion kWh per year. At present, the technology has been patented, applied for 4, and has applied for international PCT patents.
China's successful development of copper-aluminum composite pipe
On June 12, the reporter learned from Jiangsu Xingrong High-tech Co., Ltd. in Changzhou High-tech Zone that the new copper-aluminum diffusion composite high-efficiency heat exchange tube independently developed by the company can replace the copper internal thread air-conditioning pipe and copper which are currently widely used. The rate is as high as 80%. At present, the technology has passed the scientific and technological achievements of the China Nonferrous Metals Industry Association.
