Water cooled micro-hole cellular structure as a heat dissipation media: An experimental and numerical study

Abstract

Thermal performance of micro-hole cellular structure using water as a cool?ing fluid was investigated through CFD and then numerical results were validated with the experimental results. The minimum base temperature for the micro-hole cellular structure was found to be 29.7?C and 32.3?C numerically and experimentally, respectively, with volumetric flow rate of 0.000034 m3/s (2 Lpm) at a heating power of 345 W. Numerical values of the base temperature are in close agreement with experimental results with an error of 8.75%. Previously, the base temperatures of heat sinks using alumina nanofluid with 1% of volumetric concentration and water with volumetric flow rate of 0.000017 m3/s (1 Lpm) have been reported to be 43.9?C and 40.5?C, respectively.
