- Powerfin
Weight factor reduction of 30-55%, highest fin density in industry
(up to 25 fins per inch), high aspect ratios (15.1, 20.1, 25.1,
30.1), multiple fin heights from 1" to 4", up to 40%
more thermally efficient.
- Megafin
Used for extremely difficult thermal applications. Megafin's augmented
fin style brings 18% more fin area to the same mechanical envelope
as is possible with a straight fin. There is a pressure drop penalty
of 5 to 6% which is more than compensated for by the over-all
improvement in the heat sink's thermal performance.
- Tandem Sinks Utilizing the
various fin configurations of the Powerfin, it is possible to
attach two seperate mounting plates to a common set of fins. This
allows for airflow generated by one fan. The mounting plates can
be different thicknesses and if warranted, of different materials.
- Hybrid Sinks
The manufacturing ability to join dissimilar types of metal, in
particular aluminum to copper affords the opportunity to truly
optimize a heat sink for any given application. The thermal conductivity
of copper, especially in the baseplate, will create a uniquely
effective heat sink for power applications.
- Copper Sinks
Copper demonstrates twice the thermal conductivity of aluminum.
In very taxing thermal environments where rapid transfer of heat
is essential, copper heat sinks can be the last defense before
designing in a liquid cooled solution. Powersink can duplicate
all of its standard aluminum heat sinks in copper as required.
- Custom Ex Powersink works
with a broad variety of custom extruded heat sinks for natural
convection applications where lower aspect ratios are acceptable.
Typically these heat sinks are manufactured from 6063-T5 aluminum.
