本研究之主要目的為藉由開發抗鏽蝕的高轉速馬達，使其直接浸泡入水中工作來解決厚度10mm以下微型幫浦面臨的散熱以及水封等問題。藉由高轉速提高輸出壓力以及直接浸入無軸封摩擦等方法減少摩擦，目前此微型水冷幫浦已達到高過8.8%的超高效率，且在0.2瓦的低功耗下即可啟動正常運作。此外，本研究測試並開發混合螺桿之離心葉片，發現在較低轉速下這種葉片可以比純離心式葉片帶來更大的揚程。藉由開發高效率超薄型水冷幫浦實現超薄型筆記電腦用水冷散熱器，並以實際供給的市場需求為導向開發出成品，便是本研究主要貢獻。

The main goal of this research is solve the cooling and the aqua sealing problems of micro pumps that thinner than 10mm by finish a anti-corrosion high speed motor. By higher the speed of the motor and direct sank in method, this micro pump has reach a high efficiency level over than 8.8% and can work well under a low power consumption of 0.2W. Besides, this research tests and discovers a kind of hybrid screw blade than give a larger head than pure centrifugal one under low speed. To be brief, the main contribution of this research is to design a high efficiency micro pump system for laptop water cooling solution and make it a real product goes into the market.
