本研究以實驗方法探討具發泡銅材填充之鰭柱散熱座於迎面空氣流下之熱傳特性，將發泡銅材填充於方型鰭柱散熱座之軸向鰭柱間隙內，方型鰭柱散熱座之尺寸固定為：長120 mm × 寬60 mm × 高32 mm (含均熱板厚度5 mm)，發泡銅材之孔隙率為0.97。實驗之變動參數包括：鰭柱之邊長(s=5、6.3 mm)、鰭柱之軸向與橫向間隙(gL=6.33-18.0 mm、gT=7.13-22.5 mm)、發泡銅材之孔密度(20、50 PPI)、以及雷諾數(Re=3208-50069)。實驗結果指出在相同雷諾數下，A1C1 模組 (s=6.3 mm、gL =6.33 mm、gT =7.12 mm、PPI=50) 與A1C2 模組 (s=6.3 mm、gL =6.33 mm、gT =7.12 mm、PPI=20) 具有最佳的散熱能力；此外，在相同鼓風功率下，A1 ( s= 6.3 mm、gL = 6.33 mm、gT = 7.12 mm ) 與A1C2 模組具有較佳的散熱能力，其中在中低鼓風功率下，A1 模組的熱傳表現較佳，當無因次鼓風功率大於107 時，A1C2 模組的熱傳表現逐漸優於A1 模組，顯示具發泡銅材之鰭柱散熱座在高鼓風功率下的高效散熱潛力。

This study experimentally investigated the fluid flow and heat transfer characteristics of the pin-fin heat sink partially filled with copper foams under the oncoming air flow. The copper foams would be filled into the longitudinal interval spaces of the pin-fin heat sink. The dimensions of the pin-fin heat sink including a 5 mm-thickness spreader were fixed: 120 mm in length, 60 mm in width and 32 mm in height. The porosity of copper foams was 0.97. Relevant variables were the side length of the pin fin (s=5 and 6.3 mm), the space between pin fins (gL=6.33-18.0 mm and gT=7.13-22.5 mm), the pore density of the copper foams (PPI=20 and 50) and the Reynolds number (Re=3208-50069). The experimental results indicated that, at the same Re, the Model A1C1 (s=6.3 mm, gL= 6.33 mm, gT =7.12 mm and =50) and Model A1C2 (s=6.3 mm, gL=6.33 mm, gT=7.12 mm and PPI=20) had the maximum average Nusselt number (Nu). Besides, at the same pumping power, the Models A1 (s=6.3 mm, gL=6.33 mm and gT=7.12 mm) and A1C1 had the better heat transfer performances. For the low and medium pumping powers, the Model A1 had better performances. However, the heat transfer performances of the Model A1C2 would be better than that of the Model A1 when the dimensionless pumping power exceeded 107 . It demonstrated that the pin-fin heat sink filled with copper foams had the high heat-transfer potential for the system operated at the high pumping power.
