Extruded Fin Heat Sinks

A majority of heat sink currently in production are made using finned aluminum extrusions. Aluminum is lightweight, has high thermal conductivity and is easily customized & machined to fit a wide variety of applications. Recent improvements in extrusion tooling and pressing processes allow far greater fin density, more cooling surface, than was available just a few years ago. Increased cooling surface with proper air flow reduces semiconductor junction temperatures, increase power output and increases system life.
