Aluminum’s high coefficient of thermal conductivity is an asset to the designer who is trying to minimize heat build-up in a light fixture, electrical device or similar device.  Extruded heat sinks are widely used for such purposes.

Extruded heat sinks typically employ thin fins to aid with heat dissipation, and can range from relatively standard shapes like this:

Complex Shapes

With more complex custom shapes the extrusion is designed to provide additional functions – such as serving as an enclosure, or a mounting surface for electrical components.

Learn how this heatsink was redesigned to reduce weight (47% versus the previous design), increase efficiency, build in features, reduce inventory, and save overall costs.
