Heat transfer study of 3 dimensional printed air-cooled heat sinks
The study explores the heat transfer capabilities of novel heat
sinks fabricated by Selective Laser Melting (SLM), an additive
manufacturing technique, subjected to an air jet impingement.
Four different heat sinks were fabricated from AlSi10Mg
powder and they consists of a cylindrical design, and three
axially perforated designs, viz., hollow, tapered and nozzle. The
results show that the Nusselt numbers of the cylindrical heat
sink are up to 6.8% higher on average as compared to other
heat sinks. However, the heat transfer for each unit cell for the
cylindrical heat sink was worse than the other heat sinks, with
the tapered heat sink being the best, performing an average of
84.6% better than the cylindrical heat sink. This is due to the
increased surface area caused by perforations and the
minimizing of air separation within the fins. The cylindrical
heat sink was also compared with conventional fabricated heat
sinks. It was found that the 3D printed cylindrical heat sink
performs at a higher Nusselt number than the others at lower
Reynolds number because of lower thermal resistances, but
performs worse than the others at higher values due to the
enhanced fluid mixing in the porous heat sinks.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers
