Copper Cold Forging Cylindrical Heat Sink

As copper could not be extruded, and also extrusion technology has some limits on fin density and ratio aspect, if we want to build a copper pin fin heat sink, cold forging technology can help us to achieve it. Cold forging is a process which can form the copper heat sinks by using a compressed force under low temperature, Usually we will use a model die to force the copper material into fins, the fins shape can be various, from round pin fins to sqaure pin fins. 

The Benefits of  cold forging process 

1, This process can highly improve the mechanical strength of heat sink structure;

2, As the high pressure can remove the air bubbles and impurities in the material, so the cold forging process can improve the surface treatment;

3, Cold forging is a high precise process, it's better to control the tolerance;

4, It can make the material more efficiently;

5, It can improve the production ratio and save the manufacturing cost.

The benefits of  copper cold forging cylindrical heat sink

1, Copper is a better thermal conductor, so this type of heat sink has better thermal performance;

2, The cylindrical structure can improve the heat dissipation ability when the ambient air is more stable;

3, The round pin fin construction makes more surface area which means much better heat dissipation efficiency;

4, The fins come from the base, there is no joints between each other, so the heat can conduct from the base to the fins more rapidly.
