The copper heat sink is necessary because people can use it to achieve a higher level of heat conduction. In fact, the thermal conductivity of copper is twice that of aluminum, which makes it an extremely ideal substance in the production of heat sink. There are two types of radiators: active and passive. Active heat sink are those that have some kind of air mover on them. This may be a fan or blower, usually it is connected to the radiator in some way. Air flow provides localized air to help cool the hot spots of the semiconductor.

Copper heat sink are widely used, such as computer heat sink, copper cpu heat sink, BGA heat sink, server heat sink, car heat sink, etc.

Copper heat sink can be made by different kinds of process, this copper heat sink is made by stamping + extrusion + soldering process. 

Pioneer Thermal heat sink can customize heat sink based on your thermal requirement and application. More important, we can design heat sink and run simulation to find the best and cost reasonable solution for your application.
