The Flow and Heat Transfer Characteristic of Curved Channel CPU Water-Cooled Heat Sinks

Abstract:

This article conducted numerical simulation and experimental study of curved channel laminar flow and heat transfer characteristics with different Reynolds number and different heat fluxes, it also showed the comparison with straight rectangular channel of a same heat transfer area. The results showed that: cooling effect of curved channel heat sink is better than that of straight rectangular channel heat sink, temperature distribution appears to be more uniform as well; The experimental results showed that the curved channel heat sink can effectively satisfy the needs of the CPU cooling.
