Extruded Heatsinks
Extruded heat sinks, also known as extruded aluminium heat sinks, are both visually appealing and lightweight, providing exceptional heat dissipation and energy-saving properties. Their production process involves heating aluminium ingots to between 520 and 540℃ before allowing the molten aluminium to flow under high pressure through a heat sink extrusion mould with grooves. This forms the extruded heat sink material, which, after cutting and processing, creates the familiar extruded aluminium heat sinks. Due to the ease of implementation and relatively low equipment costs, aluminium heat sinks have become highly popular. AL6063 is a widely-used material for its excellent thermal conductivity and machinability.
Aluminium extrusion heat sinks are often utilised in high-power systems. Leveraging well-established technology, Setolic can offer dependable natural convection environment solutions. Complex heat sink structures can be created by extruding aluminium through a suitable die, producing intricate fins that increase surface area while decreasing both cost and processing time.
1) Features: By employing aluminium extrusion technology, the desired profile is formed before undergoing machining processes such as cutting, deburring, CNC milling, drilling, tapping, polishing, surface finishing, assembly, and packaging.
2) Advantages:
– More efficient and cost-effective compared to mechanical processing
– Custom shapes and sizes available in a wide variety
– Outstanding thermal performance
3) Capability: Maximum extrusion size: W550 x H150mm.
