Factory made aluminum foil for car radiators
The aluminum foil material of automobile radiator has high strength, good collapse resistance and heat exchange ability, and can have good sag resistance during high temperature brazing.
The aluminum foil material of automobile radiator, the core layer of which is composed of silicon, iron, copper, manganese, chromium, titanium and aluminum, is characterized in that the mass ratio of each component of the core layer is: 0.2~0.45% of silicon Iron 0.31~0.40% copper 0.30~0.40% manganese 1.0~1.8% chromium 0.005~0.035% titanium 0.12~0.20%, the rest is aluminum.
The temperature of the gasoline engine can reach 19002500℃, and the maximum pressure is 30KG/CM2. Under such high temperature conditions, the engine must be cooled in order to improve the engine’s performance.
Work efficiency, so that the engine will not be damaged. The cooling device is mainly water-cooled, using the circulating water in the cylinder water channel to cool, and the heated water in the water channel is introduced into the radiator (water tank), cooled by the wind, and then returned to the water channel. Take a car as an example. The radiator is responsible for the cooling of the circulating water. Its water pipes and heat sinks are mostly made of aluminum. The aluminum water pipes are made of flat shape, and the heat sink is corrugated. Pay attention to the heat dissipation performance. The installation direction is perpendicular to the air flow. Direction, try to make the wind resistance as small as possible, and the cooling efficiency should be high. The cooling water in the radiator is not pure water, but a mixture of water (in line with drinking water quality), antifreeze (usually glycol) and various special-purpose antiseptics, also called coolant. The antifreeze content in these coolants is 30%~50%, which increases the boiling point of the liquid. Under a certain working pressure, the allowable working temperature of the car coolant can reach 120 degrees Celsius, which exceeds the boiling point of water and is not easy to evaporate.
At present, the core material of my country's automobile radiator is mainly composed of composite brazing aluminum foil. The composite material is composed of aluminum alloy with aluminum-silicon brazing material on both sides. The working environment of automotive radiator aluminum foil is relatively harsh, requiring good corrosion resistance and collapse resistance. Because in recent years, in order to meet the needs of lightweight cars, miniaturization of parts, and lower material costs, the thickness of the aluminum foil of the material has been reduced. The thickness of the current market can only be 0.08mm, and less than 0.08mm can not meet the requirements of resistance. Collapsibility.
