The traditional methods to make
the heat sinks are Extrusion, Forging, and Die- Casting, and the maximum fins
can be manufactured with a density approximately 20 to 40 fins their thickness
or diameter. The material must mix with other metal to form heat sink with the
thick and low-density fins that can't meet the thermal solution for the CPU. Some
other method mix copper with other material to form the outer frame and brazed
or weld the fins into the heat sink, which created the interface layer about 2
to 3 degree of the heat increase between the bottom heat sink and the fins, and
also its very difficult to control the quality of the mass production heat sinks
because some poor contract or disassociate of brazed or weld fins which is not
a reliable products.
Nevertheless, Dynatron's MicroFins® Technology coolers
can eliminate all the weakness problems.
MicroFins advantage points are:
Cross Section - the cross sectional shape of the fin is skives with thin slice
with 0.35 mm and 1.0mm pitch in the 60 x 60 heat sink that is better heat dissipation.
Density - high density up to 60 fins for AMD K7 and Intel FC-PGA CPUs.
Distribution - formed ideal distribution, the fins arrayed uniformly on the base
without the interfaces, which decrease at lease 2 to 3 degree of heat source.
-applied the high quality of aluminum, and the copper to build the heat sinks
for Cooler series.
Unique High Quality - cut though the whole pieces of
aluminum or copper evenly to form up to 60 high thin fins, and all heat sinks
are unique high quality in our production line. In conclusion, taking performance
factor into account, Dynatron's CPU coolers had high-density fins 2 to 3 times
than other coolers, and reliability quality products, we highly recommend high
density fins of heat sink with high pressure drop cooling fan for your GHz CPU.
model, DC1206BM-O and DC1206BM-L in our product list, are example of a new MicroFin
CPU cooler, and it's one of the fineness in the world for the thermal management
products. The high quality of DC1206BM-O and DC1206BM-L is the best CPU coolers
to insure and protect your computer's CPU.
The process starts with a single
piece of material, typically made of either copper or aluminum. A cutting tool
contacts one surface of material and under controlled motion raises a fin, which
is form with controlled thickness, height, and center to center spacing. Fins
are uniform, consistent, and accurately spaced next one.
For Copper material:
Fin height can be 70 mm and up depends on the pitch and thickness
can be as small as 1 mm
For Aluminum material:
Fin height can ba also
70 mm and up depends on the pitch and thickness
Fin pitch can be as small
as 1.3 mm
