Advantages of Extruded Aluminum Heatsinks



Using extruded aluminum heatsinks provides a greater range of convection solutions needed for high power systems and components. By forcing raw aluminum through extrusion dies, complex fin profiles have increased surface area that allows greater heat dissipation. The time and cost of an equivalent shape using block aluminum is eliminated.

The benefits of extruded aluminum heatsinks include:

    More efficiency
    Lower costs
    Availability of many sizes and shapes
    Easy customization for any application
    Weight advantage over copper
    Mounting tools and hardware are eliminated

The latest technology is used to test and prototype extruded aluminum heatsinks to provide the most effective thermal products. Extruded aluminum heat sinks are designed for forced air cooling and natural convection. Plating options include chromatic and anodization. Multiple extruded aluminum heatsinks can be produced. Shapes include tube, solid, semi-hollow, rod, bar, profile, and hollow. Customers can also specify unique custom shapes.

The compact designs of today require one-piece aluminum heat sink extrusions. That design prevents premature failure and limits temperature rise. Heat sink extrusions satisfy a wide range of needs for semiconductor cooling. Heat sink extrusions are customized to perform optimally for any application.
Aluminum heat sink extrusions have eliminated labor-intensive, bonded-fin heat sinks. The overall size has been reduced. The original heat sink prototype was overdesigned. A thermal analysis that used maximum operating conditions, environmental constraints and a power component layout allowed a high-ration extrusion that met the thermal requirements to be developed. 

That is the process used to find solutions to heat sink extrusion challenges. Often,  heat sink prototypes that are too expensive, too heavy, or too large can be replaced by extruded aluminum heatsinks.
