[Chinalco.com] The “Heat Transfer Technology Symposium 2010†co-organized by Sapa Heat Transfer (Shanghai) Co., Ltd., Xiao La, C&W/Walker, and Solvay Fluor Chemical Co., Ltd., September 14, 2010 - A grand meeting was held in Shanghai on the 15th. Nearly 400 delegates from the domestic and international heat transfer materials industry attended the conference. At the meeting, experts from domestic and international heat transmission industry conducted a brilliant academic speech around the theme of global aluminum heat transmission industry development, application of brazing composite aluminum foil technology and pipe-making technology in the field of heat exchange, including: aluminum brazing Technological development; new refrigerant challenge for heat exchanger design; Sapa pipe growing in China; development of pre-solder MPE pipe; Sapa heat transfer rolling product – advanced material for heat exchanger manufacturing Cost-effectiveness factors in the production of microchannel heat sinks; development trend of non-corrosive fluxes; efficient and environmentally friendly CAB brazing technology and equipment; benefits and brazing of the new generation of SSR composite fins Research on the phenomenon of collapse in the process; oxidation behavior of composite foils in controlled atmosphere brazing; solutions for home air conditioning systems, thermal management techniques for hybrid and pure electric vehicles. China's aluminum heat transmission industry started in the 1990s. In the background of the rapid development of the automobile industry in recent years, the brazed composite foil company represented by Sapa Aluminum Heat Transmission (Shanghai) Co., Ltd. has rapidly emerged as a hot vehicle for Chinese auto exchange. The improvement of the aluminumization rate of the system has played an important role in promoting the lightweighting of automobiles. Sapa Heat Transfer (Shanghai) Co., Ltd. is a Spar group company based in Sweden. It was put into operation in Jiading, Shanghai in 1999. Currently, it is in a manufacturing technology and production scale for heat exchanger brazed composite foils and high-frequency welding aluminum tubes. With an advantageous level, it has become a supplier of comprehensive solutions for the heat exchanger industry. The company's sales of brazed composite tape foil increased from 18,000 tons in 2005 to 41,000 tons in 2009, a compound annual growth of 22.9%. Shang Qing Times learned from the "2010 Sapa Heat Transfer Technology Symposium" that the company's second phase project added 40,000 tons/year of brazed composite foil production capacity, and was officially put into production in the near future. At present, the company's brazed composite foil production capacity is 80,000 tons/year, and it plans to increase its production capacity to 100,000 tons/year by 2011, and continue to lead the development of aluminum heat transfer material industry at home and abroad. At the same time as Sapa Heat Transfer (Shanghai) Co., Ltd. expanded its production capacity, Shangmiao Times noticed that the company relied on the advantage of investing in millions of dollars to build Sapa's R&D center in Shanghai and intensified efforts to develop new aluminum heat transfer materials. The application market includes upgrading the heat exchange aluminization rate of heavy trucks; promoting the use of brazed radiators in the HVAC refrigeration industry; and providing aluminum brazing materials in the hybrid and electric vehicle manufacturing industries. At present, the aluminum conversion rate of China's passenger car and light truck heat exchange system has reached about 95%, which is at the same level as industrially developed countries in Europe and America. In the development and application of aluminum heat exchangers to promote vehicle weight reduction, Sapa should be effective. minister. At present, the company is accelerating the aluminumization process of China's heavy truck heat exchange system. According to Mr. Zhang Bin, the company responsible for product development, at present, there are no technical obstacles in the application of brazed composite tape foil on heavy-duty truck radiators, and Sapa users - Dongfeng Heavy Truck and heavy truck manufacturers in Shandong Province use aluminum heat. The ratio of the exchange system has reached about 60%. In the future, Sapa will continue to optimize the heat transfer materials and technologies to improve the heat exchange rate of all heavy trucks. The promotion and application of brazed radiators in the HVAC industry is an important market objective for Sapa Heat Transfer (Shanghai) Co., Ltd. The general manager of the company, Ma Yuehan, said: “At present, most HVAC® R manufacturers do not use solders. Welding radiators, and the automotive industry to use brazing radiators for energy conservation, I am convinced that for the same reason, we will see HVAC? R industry will also use brazing radiators." It is reported that the existing radiator aluminum is highly compatible with almost all commercial refrigerants. Aluminum profile miniports can be customized to meet the requirements of low pressure refrigerants (such as ammonia and hydrocarbons) and high pressure refrigerants (such as carbon dioxide). The application of brazed radiators in the home air-conditioning refrigeration industry indicates that innovations will be made in the materials of household air conditioners. Flat-flow (extrusion) aluminum tubes will replace expensive copper tubes, and brazed composite aluminum foils will replace hydrophilic aluminum foils, of course. It takes a certain amount of time for the brazing of composite aluminum materials to replace traditional HVAC materials. According to Mr. Sapa Zhangbin, it is expected that the goal of HVAC full aluminum can be achieved within 20 years. It is reported that at present the single-cooled all-aluminum microchannel heat exchanger outdoor unit has been successfully developed, such as domestic Zhejiang Sanhua, Gree and Korean-owned LG company's single cold aluminum air conditioner has achieved mass production and market. Brazed radiators will surely become a development trend in the HVAC industry. Sapa is committed to continuous innovation in the aluminum heat transfer material market and provides high value-added material system solutions for the HVAC® R brazed aluminum radiator market. Providing aluminum brazing materials for hybrid and electric vehicle manufacturing is another market goal for Sapa Heat Transfer (Shanghai) Co., Ltd. Mr. Hou Jin, Asia Pacific Business Development Manager for Hybrid and Electric Vehicles, said: “Through our extensive experience in aluminum materials and thermal management, Sapa has developed numerous products and solutions for hybrid and electric vehicle applications. As we have invested heavily in the development of aluminum products for hybrid and electric vehicles, Sapa has the ability to supply large quantities of special aluminum materials and aluminum products (such as battery housings made of brazed composite foil) for control purposes. Battery temperature and cooling power electronics to meet the performance and energy saving needs of global hybrid and electric vehicle manufacturers." Facing the hybrid and electric vehicle market with great development potential both at home and abroad, Shanghai Sapa has developed many targeted products for heat transfer materials and thermal management and developed its application technology solutions. According to research data from Shangguang Times, at present, China has more than 20 brazed composite foil producers in Shanghai Sapa, Wuxi Yinbang, and Alcoa Kunshan, with a total capacity of 300,000 tons/year or more. With the high degree of aluminization of domestic heat exchangers for cars and light trucks (tank radiators, air-conditioning condensers and evaporators), the brazed composite aluminum industry is bound to develop new applications in an increasingly competitive market environment. Such as heavy-duty trucks and new energy automotive heat exchangers, HVAC, cooling power radiators and other downstream industries. Sapa's strategy of taking a step ahead is worth thinking about other domestic aluminum heat transfer material companies. In the lighter age, it is believed that the development of a new market for aluminum heat transfer materials must possess advanced technological advancement conditions and strong research and development capabilities. Only in this way can the heat transfer material industry advance with the times.
