"Small Cooling Fan" fins (fin part): We have broken down this part, it is regarded as connected (endothermic) thermal conductivity and thermal convection and thermal radiation (heat) the most important pipeline, because the heat of the three basic condition is that the content of the formula "area, area, area", the reader may have considered Part2 and Part3 a glance, this heat sink technology and process mainly right here, and secondly, "Small Cooling Fan" anodized surface is also a very important process it is not only beautiful design, but also involves the amount of radiant heat exchange capacity, so the fin design will directly determine the product's life and death. of course, a variety of machining products have their own design considerations (some with endothermic based; some with heat-based), but if the difference between the degree far, it is a pity to see a lot of anecdotal bear witness "Small Cooling Fan" radiator, think, aluminum if known, they will certainly secretly tears it!
