High Performance Air Cooled Heat Sinks

Fabfin® Air Cooled Heat Sinks

Fabfin® is a fabricated heatsink with a height to fin spacing ratio greater than an extruded section. Fabfin® can be supplied essentially of any size where a multitude of aluminum fins of varying heights and thickness are attached by a swaging process to an aluminum baseplate of variable thickness, length and width, on four standard fin spacings. These standard spacing are designated as an FF (8.51 mm), DF (6.86 mm), AF (5.49 mm), or MF (3.43 mm) series. Typical alloy is 6063 for both fins and baseplate. Finishes are numerous. No glue is used in the process.
