The graphic processing unit is the active component that is an important heat source in electronic devices. The GPU cooling system's thermal dissipation performance with de-ionized water and nanofluid as coolants are presented. In the experiment, the GPU cooling system was embedded with the personal computer's GPU board, which in the overclock operating condition. The Ag nanofluid with 0.015% by volume concentration and de-ionized water is used as coolants flowing in the cooling system, considering the effects of coolant types and heat sink configurations on the thermal resistance. It found that the nanoparticles suspending in the base fluid significantly impact the nanofluid's physical properties and flow features, which results in higher removal capacity and, consequently, lower thermal resistance. The heat sink with a lower flow channel gives lower thermal resistance than those from higher ones. The results from this work have been used to develop a knowledge base that can be used to a design-related thermal cooling system for GPU or other components of electronic devices.

图形处理单元是有源组件，是电子设备中重要的热源。展示了GPU冷却系统的散热性能，其中使用去离子水和纳米流体作为冷却剂。在实验中，GPU冷却系统嵌入了个人计算机的GPU板，该板在超频操作条件下运行。考虑到冷却剂类型和散热片配置对热阻的影响，使用体积浓度为0.015％的Ag纳米流体和去离子水作为冷却剂在冷却系统中的流动。研究发现，悬浮在基础流体中的纳米颗粒会显着影响纳米流体的物理性质和流动特性，从而导致更高的去除能力，从而导致更低的热阻。具有较低流动通道的散热器比具有较高流动通道的散热器具有较低的热阻。这项工作的结果已用于开发知识库，该知识库可用于GPU或电子设备其他组件的与设计相关的散热系统。
