| 摘要 | .A design of inserting a concentric tube with negligible thickness to divide a circular conduit into two subchannels for double-pass flow and recyclic operations, resulting in substantially improved the heat transfer, has been designed and investigated. The results are represented graphically and compared with those in a single-pass device (without an inserting concentric tube and recycle). Heat transfer improvement IS considerably obtainable by employing such a double-pass recyclic device, instead of using the single-pass one. The effect of concentric tube location on the heat transfer efficiency enhancement as well as on the power consumption increment, has been also discussed. 圓形管內加裝一絕熱且可忽略厚度的隔板，使其形成雙套管二行程之熱量傳送的操作設計。結果顯示此種熱交換器對熱傳效率改善有相當助益，而其結果將與單行程圓管裝置（圓管內無絕熱隔板的裝置）之熱傳效率作一番比較。本研究之目的是設計增強熱傳效果的二行程熱交換器，以改善單行程熱交換器之熱傳效率，同時亦探討絕緣隔板位置對提高熱傳效果及功率消耗之影響。 |
