摘要

本研究擬利用兩相熱傳原理，製造一燒結式均熱板，分析不同粉末燒結參數探討對均熱板性能的影響。首先使用不同粉末於不同參數下進行燒結，並探討毛細結構性能之參數（收縮率、孔隙率和滲透度）之關係，藉由研究結果選擇製作均熱板內部毛細結構，並對均熱板性能（熱響應與熱阻）進行分析量測。
文中探討毛細結構發現對滲透度的影響因子中，粉末的形態遠大於燒結溫度與時間的影響，於均熱板的熱阻探討中，得到圓形粉末毛細結構的適用功率遠大於樹枝狀粉末，但於熱響應表現方面，樹枝狀毛細結構優於圓形粉末。本研究使用理論方面分析說明相互的關係。

Based on the principle of two-phase heat transfer, sintered vapor chambers were made with different powders and parameters. Besides, the performance of the vapor chambers was also discussed in this research. At first, different powder was sintered with variable parameters; factors of wick, including shrinkage, porosity, and permeability were discussed. According to the result of studying, the wick in vapor chambers was fabricated and analyzed the vapor chamber performance, involving in thermal response and heat resistance.
Factors affecting permeability in wicks, shapes of powders are more influential than that of temperature and time; in the discussion of heat resistance, the power of the round-shape powder is higher than that of arborzation shape powders. In the aspect of thermal response performance, the arborzation wick is better than round-shape powder. In this study, the inter-relationship will be explained by theory.
