Copper Cutting Heat Sink

After using the aluminum extruded heat sink for such a long time, no matter how we change our processing technology, it is difficult to meet the increasing heat generation of the CPU. Some manufacturers have to spend money on the cost and seek copper instead of aluminum. Due to the heat conduction of copper The coefficient is much larger than that of aluminum, and the doubled increase in thermal conductivity is of great benefit to our heat dissipation. However, because the hardness of copper is much greater than that of aluminum, it is a severe test for the manufacturing process during the processing. Therefore, the traditional extrusion molding process can no longer be applied to copper, and has to be processed in this way of cutting.

Aluminum and copper stack heat sink

One thing worthy of our attention is that cost and profit are always the ultimate goals pursued by manufacturers. Therefore, major manufacturers have begun to come up with more optimized solutions, using copper and aluminum sheets to be made by folding and pressing. The heat sinks of various shapes that we want are then connected with the appropriate heat sink bottom plates by welding, which not only meets our heat dissipation requirements, but also speeds up our production progress and makes mass production more easy.
