目前一般工廠既有之廢熱回收技術包含:(1)汽電共生技術(2)蒸氣製造回收技術(3)預熱回收技術,其中未回收之廢熱,大多屬於受限於空間之500℃以下之中低溫廢熱。而熱電晶片(thermoelectric generator, TEG)發電純粹依靠材料本身之材料性質,因此具有無傳動部件、無噪音、無污染、維護成本低廉、可24小時全天候操作等優點,故將其應用於工廠之中低溫廢熱回收,冀以提升整體回收之比例。另外由於煙道內壁為平整之裸管,對流效應不佳,為有效提升熱電晶片之發電功率,故以鰭片作為熱傳增強裝置。本文之主要目的即針對鰭片嵌入式熱電模組進行性能測試與鰭片幾何尺寸之參數分析。
本研究首先建立熱電模組與煙道之三維數值模型,分別計算模組發電功率與煙道內之壓降,探討鰭片幾何尺寸(鰭片高度、基座寬度與基座厚度)在不同熱側操作條件下對熱電模組熱傳與發電之關係,以及在煙道內不同流速條件下對壓降與實際輸出功率(發電功率-泵功)之關係。而為驗證數值模擬之準確性,亦架設煙道系統對熱電模組進行實驗,量測在不同熱側工作流體溫度與流速下熱電模組之性能曲線,藉以比對模擬結果,其最大誤差約15%。

Thermoelectric generators present potential applications in the conversion of low level thermal energy into electrical power. As miniature generating devices, the TEG has the advantages of compact structure, high reliability, no vibration and direct electric energy conversion.
When the thermoelectric generators are used to recover waste heat from a larger chimney plate, the TEG hot side temperature and thus the electric power output can be increased through built-in fin heat sink into the chimney tunnel to increase the convective heat transfer area. On a whole, the main purpose of this article is to analyze the effects of the geometrical parameters on both the electric power output and the chimney pressure drop characteristics. The geometrical parameters include the fin height (Lf), the fin base width (W) and the fin base thickness (H), respectively. In addition, the effects of different operating conditions include waste gas effective heat transfer coefficients ( heff = 5–40 W/m2-K ), temperature differences between the waste gas and the cooling water for TEG modules ( DT = 200–400 K ) and inlet velocities for the chimney waste gas are also discussed in detail.
