Abstract

<p>  A novel built-in CPU liquid cooling system that dispenses with a cooling fan is proposed for a high-end laptop PCs. This system consists of a liquid cooling jacket adhered to a CPU, a heat radiation flat plate on the back cover of a monitor, and magnetically driven micro-pumps. First, the size of the plate and the flow rate of coolant were determined on the basis of a thermal resistance method. Next, a micro-pump that uses a flapping elastic plate was designed and fabricated to be less than 8 mm in height, which included a drive coil. Last, to increase the load flow rate to the target value, multiple pumps were serially connected. As a result of a heating test, the liquid cooling system equipped with the two micro-pumps in series, successfully dissipated heat up to 50 W.</p>
