What are the advantages of copper cold forging heat sinks?

Copper cold forged heat sinks have the following significant advantages:

1. High thermal conductivity: The thermal conductivity of copper is about 390-401 W/(m · K), which is about 1.7 times that of aluminum. It can quickly transfer heat from the heat source to the heat dissipation surface, effectively reducing equipment temperature.

2. Precision molding: Cold forging technology can achieve high-precision molding, which can produce ultra-thin, dense fins or complex structured heat sinks, increase heat dissipation area, improve heat dissipation efficiency, and better fit the surface of the heat source.

3. Material performance improvement: The cold forging process makes the copper grain structure denser, which not only improves the strength and hardness of the material, but also further optimizes its thermal conductivity, ensuring stable heat dissipation during long-term use.

4. Strong corrosion resistance: Copper itself has good corrosion resistance, and the cold forged heat sink is not easy to rust or oxidize in various environments, with a long service life and reduced maintenance costs.

5. Environmentally friendly and recyclable: Copper is a recyclable material that meets environmental requirements. The cold forging process is relatively energy-saving and environmentally friendly.

Copper cold forged heat sinks are widely used in fields such as consumer electronics, new energy vehicles, and communication equipment that require high heat dissipation due to their excellent performance.
