中文摘要 | 本研究針對類鑽碳薄膜應用於電子產品散熱相關研究之設計與測試。係利用電漿輔助化學氣相沈積鍍膜製程於顯示卡上之散熱鰭片鍍上類鑽碳薄膜,並針對其熱傳性能效益分析。本研究以鋁質散熱鰭片在封裝前鍍上0.9μm~3.7μm等不同厚度的類鑽碳薄膜,並以實驗方式分析比較不同鍍膜厚度的類鑽碳鰭片在不同加熱功率與空冷條件下之散熱效果。類鑽碳具有高傳熱的性質有助於顯示卡晶片上的熱源可以快速傳導到散熱鰭片上,而達到迅速散熱的功能,並於短時間可有效的將熱源分散,以維持顯示卡效能並提升其使用壽命。實驗之類鑽碳薄膜厚度分別為0.9μm、1.6μm、2.3μm、3μm、3.7μm與未鍍膜之鳍片做一比較分析。實驗結果顯示,3.7μm鍍膜厚度具有最佳熱散效果,比未鍍膜之散熱鰭片之表面溫度低5℃左右,且熱阻值下降約26%。 |
英文摘要 | In this study indicated the widespread application of Diamond-Like Carbon (DLC) membrane as an outstanding protective coating in cooling electronic devices, from design and testing perspectives. The Plasma Enhanced Chemical Vapor Deposition (PECVD) will be used to coat DLC film on the cooling fins of the graphics card, and aimed at thermal performance effective analysis. The aluminum heat sinks will be plated with various thicknesses (0.9μm~3.7μm) range of DLC membrane before sealing and experimental approach analyze its cooling effect at different heating power and air-cooled conditions. Having the nature of high heat conduction, DLC could significantly raising the heat transfer from GPU and video memory chips to the cooling fins than expected, providing unbeatable cooling effect which further sustain the efficiency & performance of graphic cards and extent service life of the graphic cards in general. Diamond-Like Carbon (DLC) membrane, from thickness, is categorized from 0.9μm, 1.6μm, 2.3μm, 3μm to 3.7μm respectively. Each specified measurements are taken into cross-analysis in comparing with those DLC membrane which is not plated on aluminum. The experimental results show that the coating thickness of 3.7μm has the best heat performance, and the temperature is reduced by 5℃ on the cooling radiator with aluminum-plated DLC membrane when comparing with non-plated DLC membrane. Furthermore, the value of thermal resistance also reduces about 26% on aluminum-plated DLC membrane. |
