Triple Arc Cavity Serrated Dense Fin Extruded Aluminum Heat Sink For Inverter Cooling

This triple arc cavity serrated dense fin extruded aluminum heat sink is integrally extruded from high thermal conductivity 6063 aluminum alloy, professionally developed for thermal dissipation in industrial inverters, solar inverters, and frequency converters.

• Three Integrated Arc Cavities: Perfectly fit cylindrical power tubes and power modules for optimal thermal contact
• Close Contact Design: Eliminates need for extra fixtures and significantly reduces thermal resistance
• Dense Serrated Fins: Break static air boundary layer and expand effective heat dissipation area
• Enhanced Air Convection: Accelerates natural airflow for rapid heat discharge from long-running power devices
• Overheating Prevention: Protects against shutdown by maintaining optimal operating temperatures

After extrusion forming, we provide comprehensive CNC precision processing services including:

• Customized drilling and tapping
• Precision milling operations
• Positioning holes per your installation drawings

• Natural brushed silver finish
• Transparent anodizing
• Black hard anodizing

These surface treatments enhance anti-oxidation, anti-scratch, and anti-corrosion capabilities to extend service life.

We accept full customization to match different power-grade inverters, including:

• Overall length adjustments
• Cavity size modifications
• Fin height variations
• Fin spacing optimization
