Extruded Heat Sinks

Extruded aluminum is one of the most popular and cost efficient heat sink fabrication methods. Aavid maintains the world's largest portfolio of extruded heat sink profiles with over 5,000 tooled shapes.

Aavid extruded heat sink profiles range from simple flat back fin structures to complex geometries for optimized cooling and can be used for natural or forced convection with the use of a fan. Profiles also include a number of specialized geometries and groove patterns for use with the Aavid Max Clip System?. When these extrusions are paired with Aavid Max Clips to improve thermal performance while saving time and money on mounting and assembly. Additionally, Aavid aluminum extrusions utilize the alloys 6063 and 6061 for improved thermal conductivity. To further optimize your heat sink's performance heat pipes can be machined into the base.
