dc.description.abstract | 本研究係針對壓電磁力多重連動風扇系統整體運作情況以及於電子元件之散熱應用進行完整的分析評估。本研究當中之壓電磁力連動風扇系統係由一片壓電磁力風扇與四片磁力風扇,再運用壓電效應,磁力效應以及共振效應之結合後,壓電磁力多重連動風扇系統僅使用一片壓電片便可達成五片風扇同時產生連動效果,此連動效果進而推動氣流產生強制對流並增強散熱效果。
本研究首先進行壓電磁力連動風扇系統整體運作模式的分析,包含影響整體系統運作之磁力效應分析以及共振效應分析,在確認相關磁力效應及共振效應對壓電磁力連動風扇系統之影響後,進一步進行相關散熱效能測試平台的建立以及評估散熱能力之方法,最後針對壓電磁力連動風扇系統應用於電子元件之散熱應用進行實驗量測,並實際將壓電磁力連動風扇系統使用於桌上型電腦中進行實際應用之可行性評估。 本研究中壓電磁力連動風扇系統於桌上型電腦中進行測試所得之散熱能力相當具實際應用價值。壓電磁力連動風扇系統再輸入電壓為70V,運作頻率為30HZ,整體模組消耗功率為0.1W的情況下,於30W-90W的熱源進行散熱測試。而實際測試結果相當出色,壓電磁力連動風扇系統能夠冷卻30W-90W的晶片模擬熱源,在環境溫度為35度的情況下,保持熱源溫度在80度以下。 | zh_TW |
dc.description.abstract | This study focus on multiple piezoelectric-magnetic fan system for electronic cooling application . The multiple piezoelectric-magnetic fan system composed of one piezoelectric-magnetic blade and four magnetic blades. By applying the piezoelectric effect, magnetic effect and resonance effect, multiple piezoelectric-magnetic fan system m reaches force convection by quick vibration of all five blades.
This study first analyses the whole multiple piezoelectric-magnetic fan system, including the application of magnetic effect and resonance effect. After the system analysis, the testing and experimental platform is developed to assess the cooling performance of multiple piezoelectric-magnetic fan system. Finally, the multiple piezoelectric-magnetic fan system is actually applied in electronic element cooling to replace the traditional rotary fan. The cooling test in Desktop computer shows that multiple piezoelectric-magnetic fan system is feasible for actual application. Under the operation condition of ambient temperature 35°C, input voltage 70v, input frequency 33Hz and power consumption of 0.1w, the experimental result is excellent. The multiple piezoelectric-magnetic fan cooling system can control the 30W-90W TDP CPU temperature under 80°C | en |
