電子裝備需使用風扇-鱗片散熱座模組進行冷卻，本實驗研究主要是對於市面上販賣各種形狀的中央處理器(CPU)散熱座(具/不具風扇)來測試是否能夠將 CPU所形成的高溫降低至理想狀態，為了能夠擷取溫度數據的變化，因此使用了高精度數據紀錄平台再配合電腦中的軟體紀錄每暫態溫度的變化並採用風速計量測馬達風扇驅動之冷流風速，最後把這些數據加以計算出紐塞爾數(Nu)及雷諾數(Re)。在實驗過程當中經由電源供應器進行等熱通量加熱，其不同的加熱量將形成不同的葛拉秀夫數(Gr)，最後比較出Re 與 Gr 交互作用下對 Nu 之影響。

Electronic equipment required the use of fans - Scales heat sink the module for cooling, This experimental study is about the market selling various shapes central processor (CPU) heat sink (with / without a fan) to lower the high temperature test whether the CPU can be formed to the desired state, To be able to capture temperature data change, on this to use high-precision data records platform coupled with computer software for each the transient records to temperature changes and the use of an anemometer to measure wind speed data generated . Finally, these data calculated Niu Seer number(Nu) and Reynolds number(Re). In the experiment by power supply conducted operation of constant heat flux, its a different heating quantity will form a different Grashof number(Gr).Finally, to explore the Reynolds number(Re) and Grashof number(Gr) at interaction to Niu Seer number(Nu) affect.
