High-Density 55x55 Extruded Aluminum Heat Sink

Maximized Surface Area in a Compact Industrial Profile The High-Density 55x55 Extruded Aluminum Heat Sink is engineered for applications where thermal load outpaces available space. With a robust 55mm × 55mm cross-section and tightly spaced straight fins, this Al Extruded Type profile delivers up to 40% more surface area than standard 40mm-class extrusions—making it ideal for forced-air environments in power electronics, telecom rectifiers, and AI inference accelerators. Precision Extrusion for Consistent Thermal Performance Manufactured from high-conductivity 6063-T5 aluminum via advanced continuous extrusion, this extruded heat sink maintains uniform fin geometry and minimal dimensional tolerance across its entire length. The monolithic structure eliminates thermal interface resistance found in bonded or stacked alternatives, ensuring efficient heat spreading from base to tip. Its anodized surface provides electrical insulation and enhances emissivity for improved natural convection…
