Different Fin Configurations of Extruded Heat Sinks

Different series to meet your various requirements.

Straight Fin Extruded Heat Sink
Extruded Straight Fin Heat Sink Configuration

Straight Fin Heat Sink is a form of extruded heat sink with fins that run the entire length of the sink. This pin configuration, for example, may be seen in crosscut heat sinks, and while it is not sliced at fixed intervals, it does more efficiently draw heat away due to its significantly higher surface area.
