dc.description.abstract | 本研究旨在探討兩相式熱虹吸管在蒸發端以及冷凝端進行表面潤濕性的改
變後,所造成之熱效率以及熱阻值上的變化,而其中用來改面兩相式熱虹吸管表 面潤濕性的方法為在表面塗佈一層奈米顆粒來調整並變化不同的潤濕程度。 研究結果顯示,當蒸發端因改質而使得潤濕性愈高,其熱傳效果愈好,而冷 凝端的熱傳效果則會隨著潤濕性提高而降低。但同時本實驗也發現了當表面改質 成超疏水時,對熱傳性能所造成的一些不良影響。 在本研究中之成果顯示最好的熱傳效能發生在將蒸發端改質為超親水(10°), 並將冷凝端改質為一般疏水(120°)時,相較於純銅未改質之兩相式熱虹吸管,平 均可以增加18.2 %的熱效率,並減少一倍的熱阻值。 | zh_TW |
dc.description.abstract | This study investigated the thermal efficiency and thermal resistance of
two-phase closed thermosyphons exhibiting surfaces with various wettabilities in the condenser and evaporator sections. Nano silica particles were coated to vary the wettability of the surfaces. The experimental results revealed that, in the surface of the evaporator section, thermal efficiency increased with an increasingly wettable surface; however, in the condenser section, thermal efficiency decreased with an increasingly wettable surface. But at the same time, there was some bad effect when the surface was modified to superhydrophobic. The highest thermal performance of the two-phase closed thermosyphon was achieved when the evaporator section was superhydrophilic(<10°) and the condenser section was hydrophobic(120°). It will be possible to increase the average thermal performance by 18.2% and decrease the thermal resistance by two times compared with the pure copper two-phase closed thermosyphons. | en |
