Heat Sinks

The Aavid portfolio of standard and custom heat sinks is the broadest and widest in the world available today. From small stamped aluminum parts for cooling discrete semiconductors at the board level to extremely large thermal systems utilizing large advanced fin types and unique geometries, Aavid is the industry leader in heat sink design and manufacture.

In addition to hundreds of standard part numbers with thousands of options, Aavid provides custom cut and machined extrusions, high heat transfer fin types, industry-specific heat sinks, and advanced manufacturing techniques for better performance such as embedded heat pipes.

In 2017, Aavid Genie was launched, an online heat sink design application. Free to register and start designing, Aavid Genie allows users to design a heat sink and run a thermal simulation in minutes.Visit the website to learn more.

Skived Fin

Skiving process allows for higher fin densities and fin aspects while maintaining the integrity and thermal performance of a one piece heat sink vs bonded or brazed. Standard copper as well as custom skived fin heat sinks available.

Bonded Fin

Fins are epoxied, soldered, or brazed into an extruded or cast base in order to achieve a higher fin aspect ratio and fin density, and therefore vastly improving the heat sinks’ thermal performance.

Learn More...

Folded Fin

Fins folded in unique geometries to maximize surface area and therefore heat transfer. Fins can be purchased separately or as part of a thermal system, such as within a heat exchanger or on a heat sink.

Zipper Fin

Zipper Fin process allows for high fin aspect ratio but allows for more design flexibility. Zipper fins are extremely cost efficient in larger volumes.

Learn More...

Brazed Heat Sinks

A type of bonded fin heat sink, brazed heat sinks offer greater structural integrity and thermal performance than epoxied bonded fins. Aavid offers a number of brazing capabilities including CAB and Vacuum.
