Why Are Aluminium Heat Sink More Popular?

1. Long service life and corrosion resistance

A thick oxide film is formed on the surface of aluminum alloy, which can be used for a long time in heating water with pH ≤ 9 or in car water tanks, and Aluminium heat sink with special surface treatment can be used for a long time in various materials with pH ≤ 12. Its corrosion rate is slower than other metals and it is relatively durable.

2. Safe to use and strong tolerance

Because the specific strength and specific stiffness of aluminum alloy are much higher than those of copper, cast iron and steel. Even in the case of thin thickness, it can withstand sufficient pressure, bending force, tension and impact force, and will not damage the surface during transfer, installation and transportation.

3. Lightweight and easy to transfer

When the heat dissipation is equivalent, its weight is only one-eleventh of the cast iron radiator, one-sixth of the steel radiator, and one-third of the copper radiator. The use of aluminum alloy radiators can greatly save transportation costs, reduce labor intensity, and save installation time. Especially in special places such as high altitude, it is convenient to transfer and install the radiator, saving labor costs.

4. Simple structure and convenient maintenance

Aluminum alloy has a low density and can be processed into various shapes and standard parts. Therefore, the cross-section of this aluminum radiator is large and regular. The product assembly and surface treatment can be completed in one step. It can be directly installed at the construction site, saving a lot of installation costs. Repair is also convenient and the cost is low. If a large Aluminium heat sink is broken, you can first check which part is broken, and then replace the broken part. There is no need to replace the entire radiator. The maintenance cost is low and the time is short. Production can be quickly resumed and maintenance efficiency can be improved.

5. Cost-effective, energy-saving and efficient

The distance between the inlet and outlet of the radiator and the heat conduction temperature are the same. The heat dissipation of the aluminum profile radiator is 2.5 times higher than that of the cast iron radiator. Because of its beautiful appearance, it can be used without a heating cover, which can reduce heat loss by more than 30% and reduce the cost by more than 10%. Although the heat dissipation effect of the aluminum radiator is slightly inferior to that of the copper radiator, the weight can be greatly reduced. The price of aluminum is only 1/3 of that of copper, which can reduce the manufacturing cost of the radiator and has a high cost-effectiveness.

Summary

Aluminium heat sink are widely used in industry. The reason is inseparable from its five major advantages. Its process is complex, with multiple production processes such as smelting, die-casting, deburring, pressure testing, electrophoresis, and spraying. Aluminum alloy is easy to extrude and can be extruded into various shapes, so it has a novel and beautiful appearance and strong decorativeness. After the surface treatment of the aluminum profile, electrophoresis paint is applied first, and then the exterior paint is sprayed. The color is mellow and the appearance is extremely high.
