摘要(中) 因應下個世代處理器的散熱需求,本研究建立1 kW級泵推動兩相蒸發冷卻系統,為取代目前水冷系統在高發熱量時需較大流量及泵動力的缺點。建立系統設計不同流道高度2 mm、3 mm之直線微流道蒸發器,流道高度3 mm具有較佳的熱傳性能及較小的壓降,因其熱傳面積以及流道截面積的增加所致。而兩者工作流體流量於350 ml/min、1050 W發熱量時達到最高熱傳係數,可處理1 kW級的散熱。
  泵浦方面比較市售不同的離心泵及隔膜泵不致孔蝕現象產生的入口最低過冷度,離心泵所需最低過冷度較小,可以降低整體系統冷凝器及蒸發器的熱阻。在應用方面,考慮蒸發器及冷凝器之間的熱阻平衡,分別比較不同流體工作溫度40℃、45℃及50℃在1 kW的加熱量下熱阻的分佈,而50℃時蒸發器及冷凝器熱阻分別為0.023℃/W及0.024℃/W,達到熱阻平衡。
摘要(英) Due to the heat dissipate need for next generation processor, this research builds a 1 kW pumped two-phase evaporate cooling system, in replace the shortcoming of huge water flow rate and pumping power in liquid cooling system with high heat flux cooling. For the evaporator, we design rectangular channel with different channel height 2 mm and 3 mm, the result shows 3 mm has better heat transfer performance and lower pressure drop owing to higher heat transfer area and channel cross section. Both kind of evaporator get max heat transfer coefficient in flow rate at 350 ml/min and 1050 W heat dissipate, shows the ability to deal with 1 kW heat.
For the pump, cavitation effect needs to be avoid, so we compare the minimum inlet subcooled of commercial centrifugal and diaphragm pump, result shows centrifugal pump needs lower subcooled temperature, means decrease the thermal resistance of condenser and evaporator.
In application, the thermal resistance balance of evaporator and condenser should be considering, test different fluid working temperature in 40℃、45℃ and 50℃ in dissipating of 1 kW heat, evaporator and condenser thermal resistance meets together in 0.023℃/W and 0.024℃/W with working temperature in 50℃.
