本研究以可視化實驗觀察迴路式熱虹吸之冷凝器的現象與冷凝熱阻的量測，分為普通親水玻璃與疏水玻璃，比較兩者的冷凝現象與熱阻。另外也觀察蒸發器之現象與量測熱阻。觀察發現親水玻璃的冷凝現象為複雜凝結模式，在前段為滴式凝結；中段為過渡區；後段為膜式凝結，冷凝水會因表面張力作用，聚集成厚液膜區而流下，亦即液膜沿周長分布不均勻。而疏水玻璃之冷凝現象較單一，冷凝整段皆為滴式凝結。冷凝熱阻在考慮玻璃壁面熱阻後，可推估液膜熱阻大致在O(1) K-cm2/W。蒸發器方面，採用薄膜蒸發。其內水位高度一定，並在高熱量下，並未發現有沸騰蒸發。而蒸發熱阻在35.6 - 92.5 W時，約為0.28 - 0.14 K-cm2/W。
