Effect of Pore Diameter Distribution on Heat Transfer Capacity of Lotus-type Porous Copper Heat Sink for Air Cooling

摘要

Lotus-type porous metal with many straight pores is attractive as a heat sink because larger rnheat transfer capacity is obtained due to the small diameter of the pores. The heat transfer capacity of rnthe lotus-type porous copper heat sink was calculated using the model with the pores of uniform rndiameters. However, actual lotus-type porous metals have a distribution of pore diameter. In the rnpresent work, we investigated the lotus-type porous copper fin model by considering size distribution rnof the lotus-type porous copper fin. Prediction of the heat transfer characteristics for the lotus-type rnporous copper heat sink shows a good agreement with the experimental data.
