汽車換熱系統(tǒng)包括空調(diào)、水箱散熱器、油冷卻器、中冷器、加熱器等。它們位于前端，受到雨水、路面揮發(fā)性鹽、汽車尾氣、沙塵、泥土等的污染，以及粉末的反復(fù)冷熱循環(huán)和周期性振動(dòng)。這些都是換熱器材料選擇、防腐和連接技術(shù)面臨的嚴(yán)峻挑戰(zhàn)。傳統(tǒng)的換熱系統(tǒng)是用銅做的。然而，隨著汽車輕量化進(jìn)程的加快，節(jié)能減排、降低油耗、提高燃油效率和減少環(huán)境污染，同時(shí)由于制造技術(shù)和裝配技術(shù)的進(jìn)步，鋁在汽車換熱系統(tǒng)零部件制造中逐漸取代了銅。
　　Automobile heat exchange system includes air conditioner, radiator of water tank, oil cooler, intercooler, heater, etc. They are located at the front end, polluted by rainwater, volatile salt on the road, automobile exhaust, sand dust, soil, etc., as well as repeated cold and hot cycles and periodic vibration of powder. These are the severe challenges faced by heat exchanger material selection, corrosion prevention and connection technology. The traditional heat exchange system is made of copper. However, with the acceleration of automobile lightweight process, energy saving and emission reduction, reducing fuel consumption, improving fuel efficiency and reducing environmental pollution. At the same time, due to the progress of manufacturing technology and assembly technology, aluminum gradually replaces copper in the manufacturing of automobile heat exchange system parts.

　　鋁片、帶箔用于汽車熱交換材料可以迫使回到1930年代的歷史,其大規(guī)模應(yīng)用程序在1970年代,當(dāng)全球石油危機(jī)迫使汽車公司一千年設(shè)計(jì)方法來(lái)減少汽車節(jié)省油的質(zhì)量。而銅作為換熱材料本身就沒(méi)有多少空間，在降低汽車質(zhì)量方面鋁作為一種新型的換熱材料應(yīng)運(yùn)而生。它有很多優(yōu)點(diǎn):價(jià)格比銅低。它的密度比銅低得多，只有黃銅的三分之一，這樣可以節(jié)省燃料;鋁的可焊性優(yōu)于銅，因此焊縫強(qiáng)度高于軟釬焊銅。鋁合金防腐蝕性能強(qiáng)，換熱器使用壽命長(zhǎng)，可從6年延長(zhǎng)到8年。
　　Aluminum sheet and strip foil used in automobile heat exchange materials can force back to the history of 1930's, its large-scale application in 1970's, when the global oil crisis forced automobile companies to design methods for a thousand years to reduce the quality of automobile fuel saving. As a heat exchange material, copper has little space. Aluminum is a new type of heat exchange material to reduce the quality of automobile. It has many advantages: the price is lower than copper. Its density is much lower than that of copper, only one third of that of brass, which can save fuel; the weldability of aluminum is better than that of copper, so the weld strength is higher than that of soft soldering copper. Aluminum alloy has strong corrosion resistance and long service life of heat exchanger, which can be extended from 6 years to 8 years.
　　進(jìn)入21世紀(jì)后，鋁散熱器的應(yīng)用迅速發(fā)展。鋁合金內(nèi)部冷卻器、油冷卻器、散熱器芯等也得到了迅速發(fā)展。
　　After entering the 21st century, the application of aluminum radiator develops rapidly. Aluminum alloy internal cooler, oil cooler, radiator core and so on have also been developed rapidly.

　　汽車換熱系統(tǒng)的鋁化率已接近95%，但重型卡車的鋁化率仍較低。隨著這方面市場(chǎng)的逐步開(kāi)放，汽車換熱鋁板材料的市場(chǎng)將會(huì)越來(lái)越大。
　　The Aluminization rate of automobile heat exchange system is close to 95%, but the Aluminization rate of heavy truck is still low. With the gradual opening of the market in this area, the market of automobile heat exchange aluminum plate material will be larger and larger.
