因此本研究以市面上販售之兩種尺寸之燒結式均溫板,尺寸分別為100mmX100mmX3mm與90mmX90mmX3mm,利用水冷系統測試性能,並使用設計的五種冷卻水套進行測試,冷卻水套分別為無凹槽、直徑5mm圓形凹槽、直徑10mm圓形凹槽、30mmX30mm正方形凹槽及60mmX60mm正方形凹槽,測試結果發現,隨著凹槽變大,軸向熱阻降低,當凹槽變大到達某一尺寸時,軸向熱阻會開始增加,且可以在兩種不同尺寸之均溫板都觀察到這個現象,這是因為冷卻面積變小造成總熱阻上升,所以軸向熱阻也增加,而擴散熱阻則是隨凹槽尺寸變大而增加,因此在凹槽大小為直徑10mm圓形凹槽時,為最佳的量測尺寸。摘要(英) 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.關鍵字(中) ★ 均溫板
