The radiator we often use is made of aluminum, and its main function is to dissipate heat. Because aluminum profile materials are cheaper in the market and have better heat dissipation effects, it is a better choice to use aluminum profiles as heat sinks. Commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, too heavy (many pure copper radiators exceed the weight limit of the CPU), small in heat capacity, and easy to oxidize. the
However, pure aluminum is too soft to be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper. Some radiators take their own advantages, and a copper plate is embedded on the aluminum alloy radiator base. The aluminum profile radiator has the characteristics of beautiful appearance, light weight, good heat dissipation performance, and good energy-saving effect. The surface of the processed aluminum profile radiator is anodized for surface treatment to increase the corrosion resistance, wear resistance and aesthetics of the aluminum profile. Due to its superior performance, aluminum radiators are widely used in: machinery, automobiles, wind power generation, construction machinery, air compressors, railway locomotives, household appliances and other industries.
