中文摘要 本計畫以實驗方式探討壓電風扇冷卻平 板型散熱片之熱傳特性，實驗中探討壓電風 扇擺放之位置及散熱片幾何尺寸等參數對於 散熱效益之影響。實驗結果顯示壓電風扇葉 片位於散熱片正中央時可獲得最佳之熱傳效 益，多數情況下壓電風扇位於散熱片前端較 位於後端能獲得較好的熱傳效益。無鰭片時 熱傳效益最差，增加鰭片數目可增加熱傳效 益，在壓電風扇葉片位於散熱片前端時效果 最為明顯。
英文摘要 In this project, an experimental method is used to investigate the thermal characteristics of plate-fin heat sinks cooled by the piezoelectric fan. The effects of the position of the piezoelectric fan and the heat sink dimensions are discussed. The experimental results show that the thermal performance is the best with the blade tip of the piezoelectric fan in the center of the heat sink. In most circumstances, the thermal performance is better with the blade tip of the piezoelectric fan in front of the heat sink than in back of the heat sink. The thermal performance is the worst for the heat sink without any fin. The thermal performance enhances as the fin number of the heat sink increases. Additionally, the improvement is more obvious with the blade tip of the piezoelectric fan in front of the heat sink.
