本文以商業計算流體力學軟體FLUENT及數值逆算法配合實驗量測溫度來預測不同形式之plate pin fin heat sink(PPFHS)在不同外界風速下的熱傳特性。基於plate fin heat sink(PFHS)之設計,本文中所用之PPFHS是將一些細圓柱棒置於PFHS之間所製成。本文藉由實驗量取的鰭片底部和表面溫度以及空氣溫度後，利用逆算法預測標準試件的熱傳係數。除此之外，本文也以計算流體力學商業軟體來求得鰭片上之熱傳係數以及溫度和速度分佈。最後，將逆算法和計算流體力學商業軟體所獲得的結果進行比較，結果顯示，本文中所用之逆算法具有較高的準確性。

This article uses the software FLUENT and inverse calculation method with experimental data to forecast the thermal properties of different kind of plate pin fin heat sinks in various wind velocities. Upon to the design of plate fin heat sink, we put some pins into the PFHS to manufactory the PPFHS. In this article, we utilize the temperature which measured in the base and surface of the plate with air temperature to calculate the thermal coefficient of the standard test specimen. Besides these, we also apply the software FLUENT to get the thermal coefficient, the temperature distribution and the velocity distribution in the plate. At last, compared with the results from FLUENT, we found that the inverse calculation method has a quite good performance in estimating the plate’s thermal properties
