What is an Aluminum Heat Sink

Heat sink aluminum profiles is one of the Industrial Aluminum Profiles. It called the radiator aluminum profiles or the sunflower aluminum profiles. The heat sink aluminum profiles has the characteristics of beautiful appearance, light weight, good heat dissipation performance and good energy saving effect.

Heat sink aluminum profiles are mainly made of high pressure cast aluminum and tensile Aluminum Extrusion. Its main advantages are:

The heat dissipation of the aluminium extrusion is good, and the energy-saving features are very obvious. In the same room, if the same size radiator is used, the number of aluminum casts is less than that of steel.

Heat sink aluminum profiles has good oxidation and corrosion resistance without adding any additives. The principle is that once the aluminum encounters oxygen in the air, it will form an oxide film, which is both tough and dense, preventing further on the bulk material corrosion.

For aluminum extrusion heat sinks, it is best to choose a high-pressure cast aluminum module combined heat sink. This kind of heat sink is integrally die-casted, so there is no problem of water leakage in the weld. Moreover, its biggest advantage is that the product is not limited by the residential heating system, even in the open boiler system, it can be protected from oxygen. Due to the modular design, after a heating season, if the indoor temperature is not enough, you can add one or two more pieces to meet your needs in the second year, instead of having to replace the entire set of heating like a steel heat sink.

In addition, since the Aluminum Profile heat sink has different water quality requirements than steel, the aluminum heat sink should be avoided to be mixed with other materials.

The surface of the processed aluminum profile heat sink is anodized for surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum.

At present, the types of radiator aluminium extrusion profiles commonly used in China are electronics, electrical appliances, computer radiator aluminum profiles, sunflower aluminum profiles radiators, and power semiconductor radiator profiles.

Aluminum profiles radiators are widely used in industries such as machinery, automobiles, wind power, construction machinery, air compressors, railway locomotives, and household appliances, etc.
