Cold Forged Heat Sink

What is a Cold Forged Heat Sink?

A cold forged heat sink is produced through a cold forging process that shapes metal under high pressure at room temperature, eliminating the need for heating. It is known for excellent thermal conductivity and high structural integrity, especially when using materials like aluminum or copper. Utilizing the cold forging technique, manufacturers can minimize material waste in producing complex fin structures.

Commonly Used Materials for Forged Heat Sinks

Cold forged heat sinks are typically made from copper or aluminum due to their superior thermal properties.

Advantages of Forging Heat Sinks

• Low Thermal Resistance

Cold forging produces a one-piece structure with no thermal interface between the base and the fins, resulting in significantly lower thermal resistance. Therefore, cold forged heat sinks offer efficient heat transfer from the heat source to the surrounding environment.

• Dense Fin Structures

The cold forging process creates high-density, thin fins that maximize the surface area available for heat dissipation. With the increased surface area, forged heat sinks deliver enhanced cooling performance, especially in compact or high-power applications.

• High Precision & Customizability

With excellent dimensional accuracy and repeatability, cold forging is ideal for high-volume production. Additionally, the process supports various custom designs, allowing for optimization of fin geometry, base thickness, and overall shape to meet specific thermal and mechanical requirements.
