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。將類鑽碳薄膜鍍在顯示 卡上的散熱鰭片,然後對其散熱的影響做為研究方向,鋁製散熱鰭片在封裝前分別鍍上不同厚度 的類鑽碳薄膜,分析不同厚度的類鑽碳散熱效果。類鑽碳高傳熱的性質有助於顯示卡晶片的熱源 可以快速傳導到散熱鰭片上,而達到快速散熱的功能。有效的將熱源在短時間散掉,維持顯示卡 效能及使用壽命能有效提升。 類鑽碳薄膜厚度分別為0.9μm、1.6μm、2.3μm、3μm、3.7μm 與未鍍類鑽碳薄膜來相互作比較 與分析。經由實驗測試,鍍類鑽碳薄膜比未鍍類鑽碳薄膜的散熱鰭片溫度低5℃左右,熱阻值下降 約26%。 |
英文摘要 | The purpose of this research is to demonstrate the widespread application of Diamond-Like Carbon (DLC) membrane as an outstanding protective coating in cooling electronic devices, from design and testing perspectives. By applying DLC membrane on the surface of video cards cooling fins, the study has further to realize the cooling effects of DLC. The aim of this experimental work is to plate the aluminum heat sinks with various thickness range of DLC membrane (before sealing) to analyze its cooling effect at different stage. Having the nature of high heat conduction, DLC could significantly raising the heat transfer from GPU (Graphics Processing Unit) 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 result of this experiment shows that 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. |
