    Abstract: 本論文對蒸汽腔體均溫板(Vapor Chamber Heat Spreader, VCHS)提出廣泛性的研究工作。研製多種規格的均溫板,探討工作流體充填率與其熱傳性能的變化。並透過實驗數據分析均溫板在電子冷卻應用的影響。
    研究改變五個不同的均溫板傾斜角(0°, 45°, 90°, 135°, 180°),結果顯示在不同的傾斜角度重力對均溫板熱傳性能的影響不大,僅在90°垂直擺放時有些微差距,顯示均溫板有很好的抗重力效果。
    This dissertation presents a comprehensive research work on the vapor chamber heat spreader (VCHS). Base on the experimental data this study try to regarding parametric effects of VCHS to the electronic cooling applications. A series of prototype vapor chamber heat spreaders with different working fluid filling ratios have been fabricated and tested their thermal performances.
    To investigate the influence of the gravity on the VCHS performance, some tests were conducted under 0, 45, 90, 135, and 180 degree, five different tilt angles. It was shown that they have almost the same performance, and with little difference for the case of vertical install. The results also showed that the spreading resistance has the same trend with total thermal resistance which is a combination of the one-dimension, spreading, and condensing resistance. The spreading resistance is the dominating factor in determining the overall thermal resistance of a vapor chamber. VCHS can enhance the system performance both in air and water cooling tests.
    In this research, several VCHS with heat sink design and simulation works have been done for potential industrial applications. VCHS shows great performance under multiple heat sources condition and replaces traditional cooling modules in Blade Server, Communication System and multiple LED chips effectively.
