3003 aluminum plate for car radiator

The car water tank generally refers to the radiator (car radiator), which belongs to the car cooling system. The water tank is an important part of the water-cooled engine, as an important component of the cooling circuit of the water-cooled engine, the selection of water tank’s raw materials has certain requirements. There are two main types of car radiators: aluminum and copper. Aluminum radiators are generally used in passenger cars, and copper radiators are generally used in large commercial vehicles.

The water tank can absorb the heat of the cylinder to prevent the engine from overheating. Due to the large specific heat capacity of water, the temperature does not rise much after absorbing the heat of the cylinder. Therefore, the heat of the engine passes through the liquid circuit of cooling water, and uses water as a heat carrier to conduct heat. , and then through the large-area heat sink to dissipate heat by convection to maintain the proper operating temperature of the engine.

The 3003 aluminum plate used for the radiator of the automobile radiator belongs to the aluminum-manganese alloy, and its strength is about 10% higher than that of 1100. It has good form-ability, weld-ability and corrosion resistance. It is a widely used anti-rust aluminum plate, and it still has a long service life in some humid environments.

Aluminum alloy has high thermal conductivity and fast heat dissipation. Under the condition of satisfying heat dissipation performance, selecting aluminum alloy can improve the strength of heat dissipation parts (pure aluminum is easy to oxidize after long-term use in atmospheric environment, and some aluminum alloys can effectively resist oxidation). The heat transfer performance of aluminum alloy is better than that of stainless steel, and the heat transfer performance is directly proportional to the thermal conductivity.
