    Abstract: 本研究主要是設計並製造出可視化之平板式熱管,搭配去離子水做為工作流體,採用燒結厚度
    0.4mm 、0.7mm與1.0mm 的燒結銅粉做為熱管之毛細結構。平板式熱管在輸入功率20W 、40W及60W之
    結厚度0 .4mm之毛細結構在輸入功率為60W 時,有較佳的蒸發熱阻0.119℃/W。 透過可視化觀察,發現
    This study aims to design and fabricate a visualization flat plat heat pipe, with O.4mm, 0.7mm and
    I.0mm thick sintered copper wick structure. Three different sintering thicknesses of wicks with a series of
    filling ratio of deionized water were tested at heat input of 20W, 40W and 60W. Through a high-speed
    camera, the experiment was conducted to observe the boiling phenomenon of the evaporator in heat pipe.
    Evaporation resistance was evaluated from the measured temperature to analyze the parameters impact on
    The experimental results showed that the flat plate heat pipe at the different heat input, with the
    different thicknesses of wicks and filling ratio, which would affect thermal performance of the module, such
    as temperature of heat source and evaporation resistance. At input power of 60W, the O.4mm thick wick
    structure with 5% filling ratio has the lowest resistance of O.119°C /W. Through visual observation, the liquid
    surface would descend when the heat flux increased, and the evaporation resistance could reach a minimum
    by increasing heat flux before drying out. We also found that the main reason for affecting the heat transfer
    mechanism is the height of working fluid inside the heat pipe. When the liquid surface is above the top of
    wicks, the mainly boiling mechanism is pool boiling with higher evaporation resistance, and a thin film
    boiling occurred with a lower resistance, when the surface is below the top of wicks.
