Design of Porous-Microchannel Heat Sinks with Different Porous Configurations

Tu-Chieh Hung, Yu-Xian Huang, and Wei-Mon Yan
Abstract—The models of the porous-microchannel heat sinks (porous-MCHSs) with different porous configurations are established in this work. Thermal performances of the porous-MCHSs are investigated with the Reynolds number ranging from 45 to 1350. The results indicate that, compared with the results of non-porous MCHS, the thermal performances can be enhanced by using the porous configurations and increase with an increase in the Reynolds number, except for the case with a lower Reynolds number. Both the sandwich and the trapezoidal distribution designs have the best heat transfer efficacy, cooling performance and convective performance. In particular, the thermal performance for rectangular, outlet enlargement, thin rectangular, or block distribution design is not necessarily better than that without porous medium under lower pumping power. Finally, the sandwich distribution design is the best design of the porous-MCHSs by considering the thermal performance along with the pressure drop.

Index Terms—Porous-microchannel, heat sink (porous-MCHS).
