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 (8.5 …more

The Hollowfin heatsink is characterized by the shape of its fins which when mounted on the DF (6.86 mm) baseplate effectively duplicates the high fin density MF (3.43 mm) series, but with taller fins. A height to space ratio equivalent to 46:1 occurs when the fin height is 118 mm. The Hollowfin is an ideal candidate to be attached to a copper baseplate to maximize performance. No glue is used in …more

When our all aluminum high performance heatsinks cannot meet the operational performance required and liquid cooling is not an option, it is time to try our mixed metal solution. Weight is a cost driver and a heatsink design that incorporates an aluminum baseplate & copper fins or mixed copper and aluminum fins, provides the highest performance at the lowest cost. The mixed metal heatsin …more

Typically power modules and amplifiers are attached to a heatsink with a multitude of screws together with some form of TIM. The high thermal barrier at the interface can be eliminated by swaging a multitude of fins into a thick baseplate and then machining the module features and requirements into the baseplate. Integrated modules can be fabricated using any of the 4 standard fin spacin …more

An all copper Fabfin heatsink provides maximum forced air cooling performance. The fabrication process is the same as that for an aluminum Fabfin heatsink and is offered on MF and AF fin spacing (3.43 mm and 5.49 mm respectively). While copper provides outstanding performance, the overall cost is high. Other fin spacing can be provided when fins are silver soldered into slots. No glue is used in …more

Dual Baseplate Heatsinks (patented) increase fin efficiency with all aluminum or copper/aluminum assemblies. Mixed metal fin arrangements as well as dissimilar baseplates are available. Standard fin height, thickness and spacing are available but few mechanical constraints limit height, width, spacing or thickness of assembly. No glue is used in the process. …more

Aluminum Extrusion heatsinks are the mainstay for cooling medium power semi-conductors. Many shapes are available to fit diverse applications.  Thousands of shapes exist in the marketplace. If you do not find your needs amid our existing offerings, we will tool a new shape to meet your needs with minimum order quantities. …more
