What machining done to make qualified aluminum heat sinks?

Aluminum heat sinks are widely used don all kinds of electrical appliances and automobiles. Typical steps to make qualified aluminum heat sinks: precisely extrude the profiles(the extrusion conductivity need to be very good), cut to length, milling the bottom of base of fins to get perfect flatness(so that the bottom of heat sink can touch well with the unit in need of heat dissipating), drilling or milling some holes (for assembling the heat sink with the unit to be dissipated, usually screws are used), anodizing. Aluminum heat sinks are widely used in various electrical appliances and automobiles due to their excellent thermal conductivity and lightweight properties. They play a vital role in dissipating the heat generated by electronic components and ensure efficient and reliable operation of the equipment.
