本實驗主要研究使用在液體冷卻系統中的熱交換器，在小體積之下，製作出熱交換器內部的微流道，在本研究中將已知之技術應用到微熱交換器，其中一開始設計方式為傳統矩形流道設計，而後考慮工業界廣泛使用之板式熱交換器，將板式熱交換器的山型紋導入微熱交換器的設計中，此外將使用於氣冷之Offset Strip Fin、Louver Fin，參考鰭片設計將其應用到液冷之微熱交換器上。微熱交換器之壓降與熱傳性能經由實驗測試皆已了解並討論。 在相同的泵動力下，中心對液體熱阻由低至高依序為：山型紋、Offset Strip Fin、Louver Fin、矩形流道，山型紋在高熱通量(100W)時，仍可以維持中心點溫度在70oC以下，但是在相同流量的情形下，山型紋壓降為最高，在熱傳能力與壓降限制下可以根據需求選擇型式。 The main research of this thesis is the heat exchanger which use in the liquid cooling system. We manufacture micro-channel in the heat exchanger. In this thesis, we apply known technology to micro heat exchanger. At fast, we design traditional rectangle channel. And then, we consider chevron-type plate heat exchanger which use in industry. Using chevron-type into micro channel heat exchanger. Besides, we also consider Offset Strip Fin and Louver Fin of air cooling system, and apply fin type into micro heat exchanger. Pressure drop and heat transfer coefficient of micro heat exchanger will experiment and discuss in this thesis. Under the same pumping power, the thermal resistance between central and liquid from low to high is：chevron, Offset Strip Fin, Louver Fin, rectangle. Under limitation of heat transfer or pressure drop , we may choose the type of micro heat exchanger.
