Study on porous and solid fins and heat sinks heat transfer: A review

Heat transfer is one of the most important phenomena in nature. According to the principle of heat transfer, the best way to increase the exchange of heat from a surface,is expanding the cross section. Using porous media for increasing the cross section can be a new approach for better heat transfer. Since heat transfer by natural method has less capacity to transfer heat, using porous media in this case is more important. Due to the widespread usage of heatsinks and fins in Industry and Laboratory, designing high efficient optimized system Has been become interesting for researchers and scientist. In this study review of previous researchs in solid and porous fins and heat sinks has been conducted.
