Tree-shaped Fluid Flow and Heat Transfer

為了解決Cooling fin的問題，作者Miguel, Antonio F./ Rocha, Luiz A. O. 這樣論述：

This book provides the first comprehensive state-of-the-art research on tree (dendritic) fluid flow and heat transfer. It covers theory, numerical simulations and applications. It can serve as extra reading for graduate-level courses in engineering and biotechnology. Tree flow networks, also known a

s dendritic flow networks, are ubiquitous in nature and engineering applications. Tree-shaped design is prevalent when the tendency of the flow (fluid, energy, matter and information) is to move more easily between a volume (or area) and a point, and vice versa. From the geophysical trees to animals

and plants, we can observe numerous systems that exhibit tree architectures: river basins and deltas, lungs, circulatory systems, kidneys, vascularized tissues, roots, stems, and leaves, among others. Tree design is also prevalent in man-made flow systems, both in macro- and microfluidic devices. A

vast array of tree-shaped design is available and still emerging in chemical engineering, electronics cooling, bioengineering, chemical and bioreactors, lab-on-a-chip systems, and smart materials with volumetric functionalities, such as self-healing and self-cooling. This book also addresses the ba

sic design patterns and solutions for cooling bodies where there is heat generation. Several shapes of fin as well as assemblies of fins are addressed. An up-to-date review of cavities, i.e., inverted or negative fins, for facilitating the flow of heat is also presented. Heat trees using high therma

l conductivity material can be used in the cooling of heat-generating bodies, and can also be applied to the cooling of electronics.

超疏水性在結露狀況下對氣冷式熱交換器性能的影響

為了解決Cooling fin的問題，作者莫尼實 這樣論述：

濕空氣冷凝是熱管理系統中常見的過程，在冷凍空調循環中尤為重要，冷凝現象發生於當熱交換器，特別是蒸發器，在低於空氣露點的溫度下操作時。此現象將會導致鰭片側的冷凝液滴(膜)滯留(retention)與橋接(bridging),進而造成風機壓降與能耗的增加。本研究旨在開發一種超疏水熱交換器，通過其疏水特性，最大限度地減少冷凝水的滯留和橋接。本研究提出一種新型的超疏水性鰭片換熱器設計構想，採用傾斜鰭片排列以達到最小壓降和最大節能效果。本研究從熱傳與壓降性能的觀點切入，將新型超疏水性傾斜鰭片換熱器與其他換熱器作比較分析，分別為：超疏水水平鰭片換熱器、親水性傾斜鰭片換熱器、與親水性水平鰭片換熱器。此外，

本研究藉由改變不同的操作條件，如：進氣溫度、相對濕度和鰭片間距，對這四種換熱器進行性能測試。親水和超疏水換熱器中分別以膜狀冷凝和滴狀冷凝模式為主。由於其表面的高潤濕性，親水換熱器會有較大的液滴脫落直徑。相比之下，超疏水換熱器中發生的 Cassie-Baxter 液滴模式，促使了較小的液滴脫落直徑。本研究建立了一個力平衡模型來分析液滴脫落直徑，模型參數包括了表面張力、慣性力與重力對液滴的影響。本研究基於韋伯數(We)與邦德數(Bo)與液滴脫落直徑，引入了一個新的無因次參數( )，該無因次參數 可預測表面的凝結水脫落能力，在給定的鰭片間距下， 越小代表凝結水脫落能力越好。研究結果表明，滴狀冷凝的

超疏水換熱器在濕空氣下的冷凝熱傳性能相較膜狀冷凝的親水性換熱器並未有顯著的提升，此結果可歸因於非凝結性氣體效應。然而，在壓降方面，超疏水性換熱器與親水性換熱器相比，可帶來高達70%的壓降降低，大幅提升節能效果。壓降的降低歸因於聚結誘發的液滴跳躍現象，使得冷凝水連續脫落。
