The AeroCool
VM-102 Fanless VGA Cooler is a
pretty impressive site when you
look at it through the clamshell
packaging that it ships in, with
it wing shapes fins and two
large and long heatpipes running
through the fins you can begin
to image just how well it will
actual cool a video card.
The second
part of the kit that is equally
impressive is the 6" long, 3"
wide, 1/2" thick back plate that
will mount on the front of the
video card. |

The fins themselves measure
approximately 7" from tip to tip
and range in width
from the narrowest point up to
3/4". In total there are
30 individual fins which measure
approximately 1mm thick and are
spaced 2mm apart. The
length of each of the heatpipes
if straightened out would be
about 9.5". |

A heat pipe is a closed-loop,
cooling device wherein heat is
transferred from the
"evaporator"-end to the
"condenser"-end of a sealed tube
using the latent heat of
vaporization as the principal
means of energy transfer.
A heat-pipe consists of three
principal elements: 1) a sealed
tube (typically copper), 2) a
heat-transfer medium (such as
water, ammonia, or methanol)
enclosed under partial vacuum
within the tube, and 3) an
internal 'wick' structure.
Capillary action within the
wick transports the liquid
medium to the evaporator end of
the tube, whereupon the liquid
is vaporized by the addition of
heat, and is transported by
vapor pressure to the condenser
end, thus closing the loop. |
