Heat sink and method for manufacturing the same |
摘要 |
A heat sink and a method for manufacturing a heat sink are described. A plate-like base is manufactured with a plurality of parallel grooves and a plurality of fins by an impact extrusion process. A high temperature heat treatment is performed to soften the plate-like base. The fins are positioned in corresponding grooves and an equal force is applied to both ends of the plate-like base so that the grooves are deformed and the fins are fixedly positioned. The method is simpler and significantly cheaper than that for conventional heat sinks.
