"Micro Cooling Fan" forging heat sink is a very high pressure tap (punch) manner metallic material into the mold manipulation fin forming process problems that may be encountered on the material in the mold will hinder, that the height uneven, hot forging easier to manufacture forging and cold dense and strong fins. Advantages include high strength forging way, less surface roughness and material uniformity and the like. Forging manner fins with high aspect ratio. "Micro Cooling Fan" cutting (Skiving) fin. This is a new way to process the fins, the fins with special tooling, precision sheet such that the arcuate cut out from the metal block, since the fin and the metallic block are the same material, so there is no disadvantage then folded fin or fins. Due to the promotion process technology, is also possible to produce high density fins. Currently used is still at an experimental stage 6063 cutting aluminum, copper. Since the "Micro Cooling Fan" depth of cut can be relatively low, the thickness of the thin fin may be possible to design a high performance heat sink lighter.
