Design of Electrical Transmission Lines: Line and System Modeling

為了解決Contain的問題，作者Yenumula, Prasad/ Proteau, Gerry 這樣論述：

Line design is a very specialized field involving spatial constraints, high performance conductors, lightning protection, cable vibrations, digital terrain surveying, Fiber optic communication wires along with some exciting software developments over the past two decades. In the West, billions of

dollars are being invested on building new lines and the so-called "Smart Grid." This book will cover electrical and mechanical characteristics associated with high-voltage transmission lines, selection of conductors, line layout, thermal ratings, plan and profile drawing among other things. Struct

ures are only one component of a transmission line; as such, this book will form a companion volume to the book on structures and foundations. The book is aimed at students, practicing engineers, technicians and linemen, researchers and academics. It will contain beneficial information to those invo

lved in the management and maintenance of high voltage transmission lines and associated component systems. For those in academia, it will be an adequate textbook for (under)graduate courses centering on the topic. Asset managers at utilities and state-level electrical corporations should find the b

ook a useful reference work during system and line maintenance operations.

開孔地板對小型資料中心氣流均勻性的影響與能源消耗之實驗研究

為了解決Contain的問題，作者徐伯豪 這樣論述：

本文透過在小型資料中心中採用高架地板供風的設計，使用不同開孔率的開孔地板來實驗研究半封閉冷通道和全封閉情況下，機櫃進風量的均勻性對機房整體冷卻性能的影響。另外，特別研究了冷空氣的分配與使用性，針對冷空氣的洩漏問題進行實驗及分析。研究結果顯示在半封閉冷通道的情況下，使用阻力較大（開孔率較小）的開孔地板可以使氣流分佈更為均勻，但是會導致通道壓力增加而加劇冷空氣洩漏，使得氣流無法完全使用而造成能源的浪費。若採用散熱表現較佳的封閉式冷通道，使用開孔率較大的多開孔地板，調整開孔率由32 %提升至50 %，反而增加了氣流的均勻性，使得機櫃出口的最高溫由58.6 ℃下降至51.3 ℃，溫度的均勻性則提升了

12 %；同時，高架地板下方通道的壓力也大幅下降，通道壓力由21 Pa下降至7 Pa，這將減緩氣流在冷通道的洩漏問題，使得機櫃入口供風量的使用率由91 %提升至96 %。當機房存在著穩定且均勻的氣流之後，便嘗試改變系統供風量，以探討其能源表現的影響。實驗結果顯示降低30 %的系統供風量，空調系統的總消耗功率將節省約8.9 %，使得PUE（能源使用效率）由1.41下降至1.37。降低系統的供風量會使得冷通道內的壓力梯度有所變化，在半封閉冷通道的設計下容易產生熱回流的現象，使得通道末端的機櫃存在SHI為5～15 %的散熱表現。另外，嘗試調整空調系統的冰水溫度以探討對冰水主機能源消耗的影響。結果顯示

提升冰水溫度2 ℃，由15 ℃提升至17 ℃，可以節省約4.9 %的空調系統總消耗功，PUE（能源使用效率）則由1.41下降至1.38。調整冰水溫度將影響機房的系統供風溫度，這將改變機櫃整體入出口的平均溫度，容易在可預期的區域之中出現局部高溫熱點。

g techniques that are not covered in the textbook.

1U高熱通量伺服器氣冷散熱設計

為了解決Contain的問題，作者李昀瑾 這樣論述：

本研究針對1U (高度44.5 mm) 網路伺服器氣冷式散熱模組進行分析，總高度為29 mm單一晶片發熱量430 W，具極高熱流密度365 kW/m^2，系統內部風流量範圍為5至32 CFM。於有限的空間下藉由多款散熱模組設計，降低熱阻值以提升熱傳效能。研究針對具有熱管及均溫板之散熱模組進行鰭片設計，包括Ｖ型結構、cut-fin設計、熱管排列以及傾角溝槽，並分析各散熱器壓降與熱阻值，在相同風扇功率下與平板式散熱器比較熱阻值。模擬結果得出Ｖ型結構將大幅增加鰭片壓降，相同風扇功率下無法降低散熱器熱阻值，cut-fin設計、熱管排列以及傾角溝槽設計，具有提升熱傳效能並降低壓降的優勢，相同風扇功率下

相較於具有熱管及均溫板之平板式散熱模組有較低的熱阻值。考量機械加工性，最終將具有熱管及均溫板與特殊幾何鰭片所組之cut-fin引流模組進行打樣，置入開放式風洞系統進行性能測試。實驗結果得出cut-fin模組於風扇功率低時，熱阻值較具有熱管及均溫板之平板式模組低9.6%，隨著風扇功率提高熱阻值可降低15.1%，實驗測試與模擬所得熱阻值差異落在11.3%，鰭片壓降差異為9.3%。本研究所提cut-fin模組可有效提升散熱性能並降低風扇功率，研究成果可做為未來高功率網通伺服器散熱模組之參考。
