Square Pin Fin Aluminum Cooling Block

Designed for compact electronics that require efficient passive cooling, this product features a square body with dense vertical fins that help maximize external heat exchange area. It is suitable for routers, gateways, set-top boxes, automotive parts, cameras, and other electronic equipment that depend on stable natural heat dissipation. Manufactured from AL6063-T5 or AL6061-T5, the part uses an extrusion process to achieve consistent fin geometry, strong structural reliability, and steady thermal performance. With a thermal conductivity of 201 W/m.K, it performs well in applications where heat must be transferred quickly from the device core to the surrounding air. Its compact square layout allows the product to function effectively in limited installation space while still delivering strong cooling capability. As an Extruded Aluminum Sink, it offers a clean and production-friendly solution for customers that need precise section control and scalable volume manufacturing. The fin ar…
