毛細泵吸環路(CPL)是一個高效率的雙相移熱工具，移熱的方式主要是利用工作液體的相變化將熱能由蒸發部移至冷凝部，此裝置為自然且單向循環並不需要而外的動力裝置。
本篇論文主要是研究CPL環路系統在太陽能熱水器的應用，實驗結果顯示此CPL環路最佳填充量為70%，系統的熱轉換效率為77%。在系統傾斜實驗方式分成α-angle及β-angle；在α-angle下，當α-angle的角度愈大，系的啟動時間會愈快。效率方面，在固定加熱功率為210W下，會隨α-angle角度愈大則效率愈差。在不同加熱功率下，加熱功率為150w時，系統效率最佳角度為α30o；加熱功率為210w時，系統效率最佳角度為α0o；加熱功率為270w時，系統效率最佳角度為α30o。由不同α-angle及不同加熱總功率下，在α0o時，加熱功率為210w有最好的效率。而在β-angle下，系統效率並沒有明顯的變化趨勢，約在60%上下附近。另外，本實驗共製作四種不同蒸發部結構，分別為Wick-7pin、Wick-12pin、Wick-16pin及Wick-20pin。實驗結果發現使用Wick-12pin時系統的效率比其他三者來的佳，而啟動時間也來的最好。

A capillary pumped loop (CPL) is a high-efficiency two-phase heat transfer device in which the phase change of a working fluid is used to transport heat from evaporator to condenser through natural circulation without any external driving forces.
This study presents the possibility of the CPL apply on the solar thermal storage system. Experimental results show that the best storage efficiency is 77% in filling ratio 70%. In system tilt angle method can divided into α-angle and β-angle. In the α-angle, when the α-angle is greater the system start-up time will faster. In the efficiency, the fixed heating power 210W, with α-angle is greater of the efficiency is greater worse. the fixed heating power 150W, optimal system efficiency is α30o.the fixed heating power 210W, optimal system efficiency is α0o.the fixed heating power 270W, optimal system efficiency is α30o. By the different α-angle and different heating power, the heating power is 210w has the best efficiency in α0o. In the β-angle, system efficiency has not obvious trend, about 60%. In addition, the experiment produced different evaporation wick structure, have Wick-7pin, Wick-12pin, Wick-16pin and Wick-20pin. It was found that the efficiency of the system of Wick-12pin better than the other three structure, as well as the best start-up time.
