Multi Arc Recess High Density Serrated Fin Extruded Heat Sink for Converter Devices

This multi arc recess high density serrated fin extruded heat sink is integrally extruded from high thermal conductivity 6063 aluminum alloy, providing a dedicated passive cooling solution for all types of converter devices including frequency converters, solar converters, and power drive converters.

• Multi arc recess design at the base provides perfect fitting space for cylindrical power transistors and heating modules
• Enables tight contact between heat sources and radiator to significantly reduce thermal resistance
• High-density serrated fins break stagnant air boundary layer and enlarge effective heat dissipation area
• Accelerates natural air convection to rapidly evacuate accumulated heat during high-load operation
• Prevents overheating, performance attenuation, and automatic shutdown in converter equipment

We offer complete CNC secondary precision machining services according to customer drawings, including:

• Customized drilling, tapping, and counterboring
• Precision positioning holes to match internal assembly structure of converter housings

Multiple surface treatment options available:

• Natural brushed silver
• Clear anodizing
• Black hard anodizing

These treatments effectively improve oxidation resistance, wear resistance, and corrosion resistance to extend the service life of the heat sink.
