Increasing Air Cooling Efficiency Through Advanced Fan Modeling

The continuous rise in power dissipation levels combined with a reduced cabinet footprint is the norm in the electronics industry - a trend that is likely to continue. While advanced cooling systems such as spray cooling, jet impingement, and liquid cooling may provide solutions for the removal of high local heat fluxes, forced air cooling remains to be the most practical and the most widely used thermal management solution in practice today, largely because it is reliable and well understood. However, larger cooling demands require higher airflow rates which in turn may require novel fan designs and/or a better understanding of fan-system interaction. Increased airflow rates also come with a noise penalty. By taking a detailed look at the fan design, fan-system interaction, and fan acoustics emissions, forced air cooling can live up to its highest potential.
