What is an Extruded Heat Sink?
An extruded heat sink is a thermally conductive component formed by forcing aluminum/copper through a high-pressure die to create dense fins and baseplates. It maximizes surface area and airflow efficiency to passively or actively cool electronics (e.g., CPUs, IGBTs, LEDs). Compared to cast or machined alternatives, extrusion offers lower costs, faster lead times, and flexible structural designs.
