Abstract:	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，本研究製造高溫熱管，應用於聚焦式太陽能史特靈引擎發電系統。管材和不鏽鋼網分別由Inconel 600 及 316 不鏽鋼製成，工作流體為金屬鈉，熱管長度、外徑、內徑和管壁厚分別為420 mm、13 mm、9 mm和2 mm，充填率為10% (2.86 g)。高溫熱管以-15°, 0°, 45° and 90°傾斜角度進行啟動與熱性能測試，冷凝端維持在27°C之室溫。輸入功率設定為790 W，蒸發端溫度可達為800°C，實驗結果顯示有穿網垂直擺放之熱管性能較佳，其最低熱組值為0.18 ℃/W。 Heat pipe play an important role in middle – high temperature energy transfer system and storage system. It can be applied to the areas such as solar energy storage system and waste heat recovery. High temperature heat pipes with 420mm in length, 9mm in diameter and 2mm in tube thickness have been developed and tested. The device was made of Inconel 600 equipped with a 316 stainless-steel 100 mesh wick. The working fluid was metal sodium with a filling ratio of 10% (2.86g). Heat pipes start-up and thermal characteristics were investigated at different orientations with slopes of -15°, 0°, 45° and 90° while heat sink temperatures were kept at 27°C air environment. The evaporator temperature of 800°C was achieved when the input power was set at 790W. It has been found that the lowest value of the heat pipes thermal resistance was 0.18 °C/W when the inclination angle was at 90o.
