Abstract:	本研究設計多層組合均溫板，熱源中心上方為實心銅柱，利用銅柱較大的截面積，具較低的熱阻，能有比較高的熱傳量，有望降低鰭片上部溫度差，提高整體散熱效能。將鰭片與均溫板組合成一模組，依不同散熱需求推疊模組，達到彈性且靈活解決不同散熱目的。從熱傳實驗結果得知，在相同風速下，模組化的鰭片均溫板較非模組化鰭片均溫板具有較大的熱阻，大約5%~12%的增加，雖然熱阻略有增高，但此增加量還在可接受的範圍，因為模組化均溫板鰭片可以更快速對應不同的散熱需求。 ;In this study, a multi-layer composite vapor chamber is designed, with a copper column above the center of the heat source. Taking advantage of the large cross-sectional area of the copper column, it has low thermal resistance and relatively high heat transfer. It is expected to reduce the temperature difference on the upper part of the fins and improve overall cooling performance. The fins and the vapor chamber are combined into a module, and the modules are stacked according to different heat dissipation requirements to achieve flexibility to solve different heat dissipation purposes. According to the results of heat transfer experiments, at the same wind speed, the modularized finned vapor chamber has a larger thermal resistance than the non-modularized finned vapor chamber, which increases by about 5% to 12%. The resistance is slightly increased, which is still acceptable, because the modular vapor chamber fins can respond to different heat dissipation requirements more quickly.
