Heat Transfer of Oscillating Fluid through Finned Heat Sink with Top Bypass Clearance

Name of activity：

Keywords：Oscillating flow,finned heat sink,heat transfer,bypass clearance

Abstract：This work experimentally investigated the effect of the oscillating flow on the heat transfer enhancement of the finned heat sink with top bypass clearance.the cooling system of the finned heat sink usually employs the steady flow with fixed flow rate to complete the objective of forced convection.This work designed and manufactured a device to oscillate air flow.The experimental results indicate that it would obtain 10~34% heat-transfer increment for the oscillating-flow cases with sufficiently small bypass clearance.It demonstrates that the oscillating flow does promote the cooling performance of finned heat sink.
