Aluminum extruded heat sink is a heat dissipation product obtained by cutting, slotting, drilling and tapping, CNC and other processing on the basis of aluminum profile. Aluminum extruded heat sinks generally use AL6063 material, which has good thermal conductivity (160~180W/㎡·K) and relatively low cost. It can be used as a chassis, not only as a chassis structure but also as a heat dissipation component, or as a motherboard chip. Heat dissipation, stable performance, high-cost performance, suitable for mass production.
