What is a Cold Forged Heat Sink?
A Cold Forged Heat Sink is a precision metal cooling component manufactured through room-temperature cold forging. This process shapes metal billets under high pressure into dense fin structures without secondary machining, achieving ultra-thin fins (as low as 0.5mm) and optimized thermal conductivity. Ideal for scenarios demanding lightweight design, corrosion resistance, and high heat dissipation efficiency.
Key Features of Cold Forged Heat Sinks
- Superior Thermal Performance
- High-density fins (1.0-3.0mm spacing) increase surface area by 30-50% vs. extruded heatsinks.
- Refined grain structure from cold forging enhances thermal conductivity by 5-10%.
- Structural Integrity
- Seamless monolithic design with 20% higher vibration resistance compared to die-cast alternatives.
- Surface roughness Ra ≤0.8μm minimizes contact thermal resistance.
- Material Versatility
- Compatible with aluminum alloys (6061/6063) for lightweight applications or copper alloys (C1100) for extreme thermal loads.
- Optional surface treatments: anodizing (500+ hours salt spray resistance), micro-arc oxidation.
