Aluminium Heat Sink

What is an aluminum profile heat sink?

Radiators are heat dissipation devices used in industries such as railway locomotives and household appliances.  Aluminum profile heat sinks, also known as radiator aluminum profiles or sunflower aluminum profiles, are characterized by their attractive appearance, lightweight construction, excellent heat dissipation performance, and energy-saving effects.  Processed aluminum profile heat sinks undergo surface treatment such as anodizing to enhance the corrosion resistance, wear resistance, and aesthetics of the aluminum material.

Commonly used types of radiator aluminum profiles in the global market include electronic, electrical, and computer radiator aluminum profiles, sunflower aluminum profile heat sinks, and heat sink profiles for power semiconductors.  Aluminum profile heat sinks are widely applied in industries such as machinery, automobiles, wind power generation, construction machinery, air compressors, railway locomotives, and household appliances due to their superior performance.

Aluminum profile heat sinks mainly consist of high-pressure die-cast aluminum and extruded aluminum alloy welding. Their advantages include:
① Aluminum profile heat sinks have excellent heat dissipation performance and significant energy-saving characteristics. In the same room, the number of aluminum castings can be fewer compared to steel radiators of the same specifications.
② Aluminum profile heat sinks have good oxidation and corrosion resistance, without the need for any additives. The principle is that once aluminum comes into contact with oxygen in the air, it forms a tough and dense oxide film, which prevents further corrosion of the material.

When choosing aluminum profile heat sinks, it is best to select high-pressure die-cast aluminum modular radiators. This type of radiator is made by one-time integral die-casting, eliminating the problem of seam leakage. Its greatest advantage is that the product is not limited by the neighborhood heating system. Even in an open boiler system, it can resist oxygen corrosion. With the modular design, after a heating season, if the indoor temperature is not sufficient, one or two additional pieces can be installed in the following year to meet one's needs, without the need to replace the entire radiator system as required for steel radiators.
Additionally, since the water quality requirements for aluminum profile heat sinks are different from steel, it is important to avoid mixing aluminum heat sinks with other materials during installation."
