SEMINAR: Enhanced Convective Heat Transfer at the Micro Scale

Abstract:

In the last two decades, a plethora of novel engineering applications have emerged with stringent cooling requirements. High power density electronic components now dissipate heat fluxes in access of 1 kW/cm2 and require low temperature operating conditions. A range of enhanced heat transfer methods in micro domains have been explored, and, to some extent implemented.

This talk will introduce cooling demand and approaches that have been explored. It will then focus on a particular enhancement techniques, namely micro scale pin fin heat sinks, and discuss research effort to better understand key fundamental heat transfer and fluid flow processes controlling the performance of these system.
