摘要:	熱管在中高溫能量傳遞與儲存系統扮演著非常關鍵的角色，應用領域包括太陽能集熱系統與廢熱回收等，但目前國內並無相關設計與製造技術，因此本研究將開發高溫熱管的製造技術。應用於聚焦式太陽能史特靈引擎發電系統，熱管容器與金屬網毛細結構為不鏽鋼材質，工作流體為金屬鈉，熱管的長度與直徑為420mm與32mm。實驗以800W加熱功率與4組不同工作流體充填量進行熱性能測試，以操作時間與溫度對於熱阻之影響進行分析，結果顯示當工作流體充填量為38.13g(20%)時，高溫熱管具有最低之熱阻具較佳之性能。 Heat pipes have been considered as promising means for effective heat transfer in energy transport and storage systems in a medium-high temperature range, such as concentrated solar thermal energy systems and waste heat recovery. But up to now there is no relevant design and manufacturing technology, This preliminary study manufacturing a high-temperature heat pipe for their application to concentrating solar power (CSP) systems with stirling engine. Experiments were conducted to investigate the thermal performance of the heat pipe for input power 800 W. The container and mesh wick were made of stainless and the working fluid was sodium. The length and diameter of the heat pipe was 420 mm and 32mm, respectively. Experimental results show that a liquid fill charge of 38.13 g (20%) exhibited the least thermal resistance among four different fill charge ratios. The results were analyzed in terms of thermal resistance against time and operating temperature.
