Heat Transfer of Oscillating-Move Pin-Fin Heat Sinks with Circular Impinging Jets

Name of activity：

Keywords：Oscillation move,pin-fin heat sink,heat transfer,impinging jet

Abstract：This work experimentally investigated the effect of the oscillation move on the heat transfer enhancement of the pin-fin heat sinks with circular impinging jets.The forced convective cooling system usually applies the steady flow to pass through a stationary object.This work mounted the pin-fin heat sinks onto an oscillating platform with the impinging air jets.The experimental results indicate that strokes of the platform moving up and down as well as left and right are too long to enhance the overall heat transfer of the pin-fin heat sinks.
