本研究主要方向為發展小型側吹式風扇，並架構出快速空氣動力設計與實驗量測系統，而開發重點為設計出高風量小型冷卻風扇。
隨著電腦運算功能日益強大，其內的電子晶片所產生之熱能也隨之升高，研究的小型側吹式風扇其垂直高度不超過10mm，主要應用於筆記型電腦中央處理器散熱。設計程序為導入離心式渦輪壓縮機空氣動力設計為基礎，來完成側吹目的，而為了有效提升風量故試著改變傳統離心式壓縮機葉板與流道幾何外型，來探討其對小型風扇性能之影響，文中並完成多型風扇的實體成型與實驗量測。另外為了提升製造效率及縮短設計時程，文中亦利用美商微軟公司所提供之Excel電子試算表並搭配Visual Basic for Application語言發展一快速設計系統，藉由輸入所需之基本條件，配合簡單的點選方式即可完成包括初步葉片及流道設計，程式並提供與AUTO-CAD、I-DESA CAD/CAM設計軟體連接界面，以方便後續進行的機械設計，待實體風扇完成後，將採用AMCA 210-85標準風扇實驗程序及設備，針對各型風扇性能加以實驗驗證進而改進其設計。
綜合上述結果，開發了三型側吹式冷卻風扇，而設計的風扇最後將與現今市面上其它散熱風扇進行性能上之比較，結果顯示性能巳明顯提升。

The goal of this research is to develop the small blower fan, along with the aerodynamic design and the experimental; moreover to develop a high flow rate small cooling fan.
With the rapid development of computer efficiency, the power that is generated by the electronic chip becomes growth. The purpose of small blower fan whose altitude is below 10mm is to radiate in the CPU of a laptop. In order to blower, the procedure is uses the centrifugal turbine compressor design processes as reference. In addition, trying to change impeller appearance, which is to discuss the effects of a small fan’s function. In this research, we finished three types of blower fans.
Moreover, to increase the efficiency of manufacture and to decrease the time of design, we also use Excel which is provided by Microsoft and Visual Basic for Application, Having a simple typing way to complete this process including impeller and channel design by entering the basic information. This program also provides the interface which are design software including AUTO-CAD and I-DESA CAD/CAM. It is very convenient for people to progress the mechanical design afterwards. After finishing the fan, we will adopt standard procedures and equipment of fan experiment of AMCA 210-85. Furthermore, it can be improved the design of the function of every fan after experiment.
To sum up with, the function of this fan compared with other hot fans that were available in the markets. The result indicated that the function was raising.
