    Abstract: 市面上各家廠商對於均溫板性能之量測皆有不同的測試方法,導致各廠商測量出之實驗數據並沒有比較的相關依據,造成各家廠商難以正確比較其產品性能之優缺、效能之好壞,使市面上均溫板好壞參差不齊,如果能制定標準實驗方法,也就能解決這個問題。

    ;For each company have different vapor chamber performance testing method. So they can not compare the vapor chamber performance that made by different company. That was why the market is flooded with cheap-jack vapor chamber. If we can establish the standard vapor chamber testing method. Then we can solve this problem.

     Accordingly, this research uses two kind of different size vapor chamber(100mmX100mmX3mm and 90mmX90mmX3mm) to do the experimental. And this study uses the water cooling system to test the vapor chamber performance. We design the five cold plates that have different hole size.(no hole, diameter 5mm hole, diameter 10mm hole, 30mmX30mm square hole, 60mmX60mm square hole) then we use these cold plates to test the vapor chamber. In the result show that larger hole size will increase the axial thermal resistance and spreading thermal resistance. When the hole size reach to certain size, the axial thermal resistance will decrease. Because of the larger hole will decrease the heat transfer area. Let the total thermal resistance increase. So the axial thermal resistance will increases. In this research. The diameter 10mm hole is best one to measure the vapor chamber performance.
