电子冷却由于其高热流密度的特点，仍然是一个具有挑战性的课题，需要进一步的探索和研究。微通道是满足这一要求的几种高热通量散热设计之一。纳米流体表现出显着增强的热导率以及强的温度和尺寸依赖性的热物理性质，并且可以通过在传统的液体工作流体中添加直径小于100 nm的固体颗粒来实现。纳米流体有望在微通道热沉中用作冷却剂，以获得强化传热的双重效益，以满足电子器件日益增长的冷却需求。以奈米流体为冷却剂的微通道热沉是否能对电子元件提供良好的冷却？本工作的目的是：（1）通过检查Al 2 O3/H2O纳米流体对改善微通道热沉的整体性能的有效性，提供用于MCHS的合适纳米流体的标准;（2）回答Al 2 O3/H2O纳米流体是否/何时适用于MCHS。
Electronic cooling remains a challenging subject that needs further exploration and research due to its increasing high heat flux. The microchannel is one of several high-heat-flux heat removal designs to meet this requirement. Nanofluids exhibit dramatically enhanced thermal conductivity as well as strong temperature- and size-dependent thermophysical properties, and can be achieved by adding solid particles with diameters below 100 nm in the traditional liquid working fluid. Nanofluids are expected to be utilized in microchannel heat sinks as coolants to gain double profits in heat transfer enhancement to meet the increasing cooling requirements of electronic devices. Does the microchannel heat sink (MCHS) using nanofluid as coolant always provide good cooling to the electronic devices? The answer is No. The aims of the present work are: (1) to provide the criteria for suitable nanofluids for MCHS by checking the effectiveness of Al2O3/H2O nanofluid on improving the overall performance of microchannel heat sink; (2) to answer if/when Al2O3/H2O nanofluid is suitable for MCHS.
