摘要(中) 本研究將針對水對水在凸出凹入型與山型紋板面型式之板式熱交換器的熱傳及壓降性能，進行實驗分析，並提出預測板式熱交換器熱傳及壓降性能之半經驗關係式比較。測試板片型式分別為凸出凹入型與山型紋板片。山型紋板片幾何參數，傾斜角越大，流體越容易轉變成紊流，使得熱傳量與壓降皆增加。
凸出凹入型板片雖然也是使流體在低流速下轉變為紊流，使得熱傳增加。但效果卻沒有山型紋板片佳。壓降方面，凸出凹入型板片之摩擦因子比山型紋小但隨雷諾數變化較大。凸出凹入型板片熱交換器比山型紋板片熱交換器密集，對空間上有限制時，凸出凹入型板片之熱交換器是可以考慮使用的。關鍵字(中) ★ 熱傳
★ 壓降
★ 凸出凹入型板片
★ 山型紋板片
★ 板式熱交換器關鍵字(英) 論文目次 摘要----------------------------------------------------------------------------------- i
