Copper Brazing Technology Used in China Automotive Radiator Industry
With the gradual increase of the service life of automobile engine and automobile important spare parts, consumers and OEM manufacturers urgently need to solve the problem of low reliability and poor maintainability of some heat exchangers. This time, Nanning Bading Technology produces automotive heat exchangers with high corrosion resistance, high strength, easy maintenance, and long service life, which will provide domestic OEMs with more possibilities for selecting high performance and long life heat exchangers. . At the same time, as China’s environmental protection agencies adopt the Euro II and III and IV emission standards one after another, manufacturers of the automotive industry, especially heavy-duty vehicles, will need to provide exchangers that resist higher operating temperatures and smaller volumes. The implementation of this project will undoubtedly be implemented. Provides a rare solution for the industry. It is believed that in the near future, automotive heat exchangers adopting the new copper brazing technology will inevitably replace traditional technology products and will be better applied to large-scale equipment such as pickup trucks, heavy-duty trucks, construction machinery, diesel locomotives, and ships. Nanning Baling Technology Co., Ltd. was established in July 2001. It is a high-tech enterprise created by Nanning Baling Auto Parts Co., Ltd. and individual shareholders. The company used the 2000 national debt project to invest more than 80 million yuan to complete the new copper brazing double wave belt automobile radiator technological transformation project, becoming the first Chinese company to adopt this new technology. The chairman of Nanning Baling Technology Co., Ltd. said: “The new copper brazing double wave belt automobile radiator technological transformation project produced by our company has truly filled the domestic gap and is the latest achievement in the world of automotive heat exchanger technology. It plans to produce about 500,000 copper brazing automotive heat exchangers each year to meet the needs of domestic and foreign markets.†Director of Outokumpu's Asia-Pacific region, Outokumpu Guo Luma, also stated in Nanning: “The advantages of the late start will allow China, an excellent developing country, to choose its own technological development path from a higher starting point. With years of hard work, we are very pleased to see that Chinese companies have started to introduce copper brazing as the latest international technology. The successful cooperation with Nanning Baling Technology Co., Ltd. marks that the copper brazing technology has been acquired in the Chinese market. Approved." Background information: Nanning Baling Technology Co., Ltd. parent company - Nanning Baling Auto Parts Co., Ltd. Founded in April 1995, the company implements modern enterprise management and production methods, adhering to the "achievement of customers, achievement of eight-ling" ideas, the current major supporting markets are Dongfeng Motor Corporation Liuzhou Automobile Factory, Dongfeng Motor Company Truck Company, Changan Automobile The company, SAIC-GM-Wuling, FAW Liuzhou Special Vehicle Factory, Liuzhou Construction Machinery Plant, Chongqing Changan Suzuki Automobile Co., Ltd., Chongqing Heavy-duty Truck Group Co., Ltd., Nanjing Changan Automobile Co., Ltd., Yuchai Machinery Co., Ltd., etc. At present, the company produces more than 500,000 double wave belts and ordinary wave belt car radiators each year. About Copper Brazing Technology and Intercooler (CAC) In response to the market demand for a new generation of copper-brass radiators, the International Copper Association has developed copper brazing technology for the production of automotive heat exchangers. Using copper brazing technology, intercooler manufacturers can create better intercoolers that can withstand higher temperatures than existing products. Therefore, the replacement of aluminum intercoolers with products made of brass-brass by copper brazing can enable the transportation industry to reduce pollution emissions and increase fuel efficiency. In the area of ​​intercooler applications, pressurized hot air passes through the heat pipe. The specially designed internal heat sink and the high thermal conductivity of copper will make heat transfer to the heat pipe wall and the external heat sink easier. The traditional intercooler is made of aluminum, but the new copper brazing product offers many significant advantages in terms of cooling performance and durability, especially high temperature performance. Outokumpu OYJ Outokumpu OYJ is an international company principally engaged in the non-ferrous metals business. It has 20,200 employees and annual sales of about 5.6 billion euros. As one of the major producers of copper products in the world, the company accounts for about 10% of the global market in copper product market share. As a wholly-owned subsidiary of Outokumpu Group, Outokumpu Copper Belt Co., Ltd. started researching and developing copper brazing technology and production process together with the International Copper Association from the end of the 1980s. So far, the company has conducted more than 100 assessment projects worldwide, of which more than half are directly related to the automotive industry.
