This paper describes fundamental heat transfer performance of porous metal sheet under natural convection condition. In recent years, passive cooling techniques are required even in high heat generating electrical device because of miniaturizing of equipment and not enough space for cooling. Porous material sometime acts as thermal insulator due to its high dense air contents. However, if the material is metal and has high porosity, it is possible to behave as a heat sink. In this study, several types of porous metal was prepared and fundamental cooling performance as a heat sink was evaluated.
