What is an Extrusion Heat Sink?

An extrusion heat sink is a type of heat sink manufactured using aluminum extrusion technology. This process involves shaping aluminum, commonly AL6063, into various profiles with excellent thermal conductivity and machinability. The extrusion method is favored for its simplicity and cost-effectiveness, making it a popular choice for a range of applications.

The extrusion process allows for the creation of complex heat sink fin structures, which are then typically anodized to enhance corrosion resistance, wear resistance, and appearance. Commonly used extruded aluminum heat sinks include electronic heat sinks, computer heat sinks, sunflower heat sinks, and power semiconductor heat sinks.

Due to their superior performance and versatility, extruded aluminum heat sinks are widely employed in various industries, such as machinery, automobiles, wind power, construction machinery, air compressors, railway locomotives, and household appliances. The ability to mold aluminum into a wide range of forms allows manufacturers to meet diverse cooling needs and spatial requirements efficiently.
