Unsteady air flow cooling of electronic devices
M.Sc. thesis of David Altura This research shows that we can improve the fan-heat-sink cooling system performance in two aspects:
Increasing convective heat transfer and,
Maximizing the coefficient of performance (COP) by applying an unsteady but controlled fan operation.
The presentation gives some highlights of this research: PDF Final year project of Maya Beckerman Cooling of PC using unsteady convective heat transfer We have transparent PC case with installed air flow ventilation, see the images: The project is experimental:
Make the air cooling system working with an external controller that enables to turn on/off any combination of the air flow ventilators
Make flow visualization with smoke or aerosols
Measure the flow in the case
Analyse and propose for an optimal configuration of air fans.
