It's called the T-Shooter heatsink. It's
new, really new, and based on a completely unique fluid dynamics concept for
utilizing air vortices.
It was designed by Mr. Kusumoto and made by Japanese extruded
aluminum manufacturer Fuji Light Metal. The T-Shooter is an entirely
new heatsink concept that relies on four air vortices created within
a distinctive quad-barrel aluminum extrusion. In place of standard aluminum
cooling fins, the inside of each cylindrical barrel is lined with approximately
40 stubby finlets.... in a way this heatsink has a lot in common with a Dyson
vacuum cleaner, except that the T-Shooter is built with quiet performance
cooling in mind.

The T-Shooter's strange design is based on mathematical models of
fluid dynamics principles. Air is drawn in at the bottom of the heatsink
where a section of each aluminum barrel wall is cut away, closest to the
processor. A fan at the top of the heatsink, connected by a plastic "air handler"
exhausts outward, so as the air travels from the bottom to
the top of the four aluminum barrels it does so in a vortices,
passing over the surface of the internal stubby aluminum finlets many
many times. Essentially the heatsink design creates a situation where
airflow spins around and around, so it passes over the aluminum surface for
a significantly longer period than is the case with standard impingement heatsinks
where a lot of air is constantly moving through the fins of the
cooler.

A heatpipe (or heat column) is built into the central column of the
T-Shooter to help conduct heat from the processor vertically and disperse
it through the aluminum body.
Mr. Kusumoto has four variations on the T-Shooter heatsink in the
works, the four barrelled version currently available (shown here), and a six
and eight barrelled version still in prototype stage. The first four barrelled version of
the T-Shooter heatsink is only available in Japan, but by
the fall of 2009 T-Shooter Version.2 is expected to be
available globally.
