SINOPSIS

As a result of increasing power demands and the decreasing size of computational hardware, the need for an effective cooling technique is more urgent now than ever. Despite this need, there is insufficient research on metal foams operating as liquid cooling heat sinks within electronic systems and documented cases where the results are reported and verified using both experimental and numerical analyses. Operating within the Forchheimer flow regime, the present paper assesses the effect of varying pore densities on the thermal effectiveness of metal foams as liquid cooling heat sinks for electronics. The effectiveness of the system is evaluated based on the pressure drop that occurs across the metal foam and the effective heat transfer rate. These results are then verified both numerically and experimentally. The results revealed that a sample with a linear pore density of 10 PPI is most effective when all the evaluation parameters are taken into consideration.
