As the nation has set new requirements for the energy conserving buildings and constructions, some old types of auto radiators have failed to meet the demand of the consumers. For a long time, the cast-iron radiators accounted for most of the proportion of the heating radiators that used in residences and buildings. However, this type of radiators can cause environmental pollution and raw material waste. Therefore it is inevitable for the cast-iron radiator being gradually displaced by the high quality light heating radiator with decorative appearance. Along with the development of cities and towns, the building material industry will be driven by the building trade which has recently become one of the support industries.

In the last few years, the aluminum racing radiators have rose as a new burgeoning type of heating plant. This type of radiator is welded in various combinations by several section bars which are made of aluminum, magnesium and silicon alloy through the process of pressing and heating. With numerous advantages of radiator fan shrouds including light weight, good thermal conductivity, splendid pressure resistance, high envelop thermal performance index, metal thermal intensity which can reach 2.4W/kg°C and ideal price performance, the aluminum alloy radiator has swiftly become socially acceptable. The aluminum radiator industry has been developing rapidly in recent years, thus the number of manufacturers in the industry has soared by over 600%.

Provided with high thermal conductivity, the aluminum alloy maintains fine heat dissipation which determines its position of the most perfect dielectric for conversing of thermal energy. Considering its good flexibility, the aluminum alloy can be formed into various styles of radiators with innovative and decorative design through the extrusion forming technique. Moreover this kind of radiator is mainly featured by its high heating efficiency, light weight and easy-to-processing. As a matter of fact, the aluminum alloy radiator is the lightest among all kinds of radiators, which make it convenient to transport and 3 times lighter than the steel one in the same standard. Furthermore, with a layer of alumina preservative generated by the oxidation of aluminum to prevent it from further oxidizing, the aluminum alloy radiator is oxidation corrosion resistant. Apart from all the advantages mentioned above, its reasonable price is another factor in result of its popularity among the working class.

However, currently a substantial part of firms in this industry are running in small production scale. The technologies of these firms have yet to be improved. On the basis of the current quality of water in the heating system, the possibility of leak in the early stage will largely raise when the aluminum radiator is put into use directly without any internal anti-corrosion measures to prevent corruption, for it might cause future trouble. . In order to prolong the service life of the discount Acura radiators, taking internal anti-corrosion measures should be taken in to account. It is high time to attach great importance to the fact that most of the firms have not taken measures.
