Recently, Jiangsu Xingrong Hi-Tech Co., Ltd. developed a new high-efficiency heat exchange tube--copper-aluminum composite pipe. The composite pipe successfully realizes the metallurgical combination between copper and aluminum. The energy efficiency ratio of the single pipe is 39.2% higher than that of the original copper pipe. In practical applications, the energy efficiency ratio is also increased by 5% or more, and the copper consumption is reduced by 80%. After the national air conditioner manufacturers fully adopt, they can save more than 2 billion kilowatt-hours per year for the national energy-saving enterprises, saving more than 8 billion yuan for air-conditioning enterprises.
