The aluminum fin heat sink with black anodizing (or coating) is made of high-quality aluminum alloy and is precisely machined. The densely arranged fins on its surface greatly expand the heat dissipation area. With the black anodizing layer or nano coating, it not only gives the product a cool appearance, but also significantly improves the corrosion resistance and wear resistance. Without complicated installation, it can efficiently remove the heat of electronic components through natural convection or with fans. It is an ideal choice for heat dissipation of computer hardware and industrial equipment.
