Copper Block Heat Sink

The main material of heatsink is copper and aluminum, the aluminum heatsinks are efficient for most applications as aluminum owns a good thermal conductivity character, also it has low cost, lightweight benefits. But in some situations copper heat sink is essential due to the higher level power applications, the aluminum heat sink could not achieve the thermal requirements.

Compared with aluminum, copper is a better thermal conductor, for some high power devices, copper heat sink is necessary although it's more expensive.

As copper can't be extruded like aluminum, the main solid copper block heat sink forms are copper skived fin heat sink, cold forged heat sink, die-casting heat sink, and machined copper block.

How to select a right copper block heat sink?

Heat sink is a component for a completed module to absorb and transfer the heat which created by the electronics and other applications, so choose an appropriate heat sink is mandatory for your device. If the high fin density and thinner fin is required, the skiving fin technology can play a important role to achieve it, skiving fin heat sink is produced from a solid piece of copper block, it has great thermal conductivity and dissipation. If you want to have a good performance heat sink in fluctuated fluid circumstances, cold forged heat sink is an excellent choice. If the cost is the first consideration, die-casting heat sink would meet the request.

There is an alternative type for a solid copper block heat sink, it's very common that we solder the copper base with aluminum zipper fins, for high power applications, we offen embed some heat pipes or vapor chambers to improve the thermal performance. This heat sink is a perfect type as it unites the benefits of two materials, the copper has a better thermal conductivity and the aluminum has better heat dissipation ability, this combination can save the cost and maximum the performance.
