兩平行板管道內加裝一絕熱且可忽略厚度的薄片，使其形成為上下兩通道之雙流式熱量傳送的操作設計，結果顯示此種設計對熱傳效果有相當大的改善，而其結果將與單流式裝置〈兩板間無絕熱薄片〉的作一番比較。本文即研究設計此種可增加熱傳效果的雙流式交換器，以改善單流式熱交換器之效率，同時亦探討絕緣薄片的放置位置對熱傳效率之提高及功率消耗之影響。
A design of inserting in parallel an insulation sheet with negligible thickness to divide an open duct into two channels for double-flow operations, resulting in substantial improvement in heat transfer, has been designed and investigated. The results are represented graphically and compared with those in a single-flow device (without an inserted insulation sheet). Considerable improvement in heat transfer is obtainable by employing such a double-flow device, in-stead of using the single-flow one. The effect of insulation-sheet location on the enhancement of heat transfer efficiency as well as on the increment of power consumption, has also been discussed.
