散热水箱是汽车的一个重要组成部件,自70年代以来,铜材与铝材是散热水箱中相互竞争的材料。铝材水箱的主要优点是重量轻,一般比铜材制的轻40％左右,这就是铝材水箱越来越受到重视的根本原因,因为降低汽车自重,对于节约能源有着特殊重要的意义。最近,日本刈谷市田宗公司推出的超级汽车散热水箱(见美刊Modern Metals 1990年第10期第30～36页)的重量比铝材水箱还轻25％,同时其抗蚀性比铝材水箱又高一倍。这样一来,铝材水箱将面临着严峻的挑战。这种新一代的散热水箱又称超级水箱,其散热片是用0.038毫米厚的复合钢材制的,而这种复合铜带是用轧制法生产的,与轧制包铝的铝合金板
Cooling water tank is an important component of the car, since the 70s, copper and aluminum materials are competing radiator cooling tank. The main advantage of aluminum tanks is light weight, generally about 40% lighter than copper, which is the root cause of the aluminum tank more and more attention, because reducing the weight of the car, for energy conservation has a special significance. Recently, Tian Zong Co., Ltd., Kariya City, Japan launched a super car radiator tank (see the publication of the American Journal of Modern Metals No. 10, 1990 page 30 ~ 36) lighter than aluminum tanks also 25% lighter, and its corrosion resistance than aluminum Tank twice as high. As a result, aluminum tanks will face serious challenges. This new generation of cooling water tank, also known as super tank, the heat sink is made of 0.038 mm thick composite steel, and this composite copper strip is produced by rolling method, and rolling aluminum clad aluminum plate
