隨著熱電技術的開發，相關熱電晶片的應用與研究也愈來愈受重視，車輛引擎系統本身具有加熱源與冷卻源，對熱電晶片的溫差發電提供良好的運用環境，而熱電晶片冷、熱端的溫差愈大，愈能獲得理想的發電功率，要增大溫差，就要利用熱傳增益技術使熱電晶片兩端分別與加熱源與冷卻源產生最佳的熱交換率。金屬多孔性介質具有高散熱面積及重量輕之特性，已獲證明為優良的熱交換器，但多孔結構會降低等效熱傳導能力，因此若能設計適當鰭柱當成導熱柱，彌補金屬多孔性介質其熱傳導能力下降的缺點，將成為新穎的高效率熱交換器。本文將以實驗方法觀察充滿銅纖維條堆疊物之鰭片散熱座於矩形通道內之強制對流熱傳特性，採用空氣為冷卻流體，測試段分成：方形鰭柱散熱座具堆疊銅纖維條(Model A)、蛇形通道散熱座具堆疊銅纖維條(Model B)、片狀鰭柱散熱座具堆疊銅纖維條(Model C)與純粹堆疊銅纖維條(Model D)，並建構一熱電轉換平台， 以前述測試塊作為集熱座，實際測試對應之發電效能，相關研究結果將可做為未來設計車輛引擎系統之熱電轉換裝置的集熱座構型的重要參考。

Since that the thermoelectric technique is highly developping now, the relevant applications and studies of the thermoelectric generating modules is more and more emphized. The engine system of the vehicle can provide the heating and cooling sources to the thermoelectric generaters (TEGs) to result temperature difference for generating the electricity. If the temperature difference between the hot and cold sides of the TEGs is large, the electric power will be generated well. Therefore, using the heat transfer enhancing technique to promote the heat-exchange capacities between the TEG’s hot side and heating source as well as the TEG’s cold side and cooling source should enhance the generating performance of the TEG system. Although the porous structure reduces the effective thermal conductivity of the metal porous medium, It has demonstrated that the metal porous medium, with the large heat-exchange area and light weight, is the good heat-transfer material. This study tried to couple the metal porous medium with the finned heat sink to obtain the optimal heat transfer performance. The forced convection heat transfer characteristics of a rectangular channel fully filled with the finned heat sink and packed copper fibers were investigated experimentally. The coolant is air. Four configurations of test sections were employed: the square pin-fin heat sink with packed copper finers (Model A), the serpentine-channel heat sink with packed copper finers (Model B), the plate-fin heat sink with packed copper finers (Model C) and the pure packed-copper-fibers heat sink (Model D). The above-mentioned test sections awere used as the heat absorber of the TEG system. A thermoelectric conversion platform was built to measure the really generating power. The relevant results can be the important base in designing the vehicle’s TEG system.
