碩士 === 國立中央大學 === 機械工程研究所 === 94 === 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.
