There are multiple aluminum heat sinks available in the market. Let’s look into the below heat sinks you definitely want to know about.

  • Stamping Heat Sink

Aluminum sheets are stamped in press in a process called die stamping to make stamping heat sinks. The designs are based on the intended application.

The result is two parts of heat sinks with base and stamped fins. The fins increase the heat sink’s strength and gives the manufacturer an opportunity to make multiple sink designs.

  • Folded Fin Heat Sinks

Folded fin heat sinks are produced by bending aluminum material in a fan/fin shaped structure. The result is thinner heat sinks with relatively higher aspect ratios.

The fins are then soldered to base for strength. In addition, heat pipes may be introduced for heat transfer. Since there are passive heat sinks, they’re used in combination with a fan to ensure proper air flow.

  • Machining Heat Sinks

This is accomplished through laser and CNC machining. The aluminum heat sinks produced are very economical but designs are limited.

  • Extruded Heat Sinks

These ones are cost effective and offer one of the best thermal performances. They are produced through extrusion using alloy 6063-T5. The alloy is utilized because of superior mechanical properties as well as thermal attributes. We can attest that it’s true the extruded aluminum heat sinks bear low production costs, especially when produced in large quantities.

  • Standard Extruded Heat Sinks

We, at FONNOV Aluminum offer variety of heat sinks upon request. Our standard extruded heat sinks have been expertly developed through extrusion with proper and standard procedures observed. After extrusion, the heat sinks are cut according to requirements, machined, and finally anodized.

We also elongate the sinks after production. This customization allows us to meet client specific needs especially those that are size related.

We have round and straight standard heat sinks. The round standard extruded heat sinks are of two types including hollow and solid type. Their outside diameter (OD) and inside diameter (ID) vary in ratios.

The straight fin type heat sink has ratios calibrated in mm, measured as weight versus height. The ratios available on our stock range vary a lot.
