FINNED METAL FOAM HEAT SINKS FOR ELECTRONICS COOLING

摘要

Our experiments on novel firmed metal foam heat sinks reveal superior thermal performance in both forced and natural convection compared to longitudinal filmed heat sinks. We expect this advantage to be further enhanced when the finned metal foam heat sink configurations are optimized. Analytical expressions for Nusselt numbers have also been developed in both forced and natural convection [Bhattacharya and Mahajan (2000) (1,2)].
