This Small Business Innovation Research (SBIR) Phase II project will develop a compact, light-weight and noiseless cooling system for laptop computers. The product will be an air cooled, micro-channel heat sink with an electro-hydrodynamic (EHD) pump integrated within the channels. Research will focus on the development of a heat sink with a large parallel array of micro-channels to provide optimal thermal resistance. The second major area of development will be the EHD air flow device; a modification to the corona wind technique will be used to provide air flow through the heat sink. Other tasks include power supply development, system integration, manufacturing process development and reliability improvement. As the speed and performance of laptop computers increases, the power density in the microprocessors rises and they dissipate more heat. The proposed project addresses the fact that laptop computer cooling systems will be required to dissipate upwards of 40 Watts while maintaining the microprocessor below 85 degrees C.Commercially, the proposed cooling system is being developed for the growing laptop computing market. More than 235 million personal computers will be sold in 2007; roughly one-third of which or about 80 million will be laptop computers. The proposed product's small size and excellent heat dissipation capabilities will enable laptop computer manufacturers to incorporate faster processors while simultaneously reducing the overall size and weight of their products. Besides cooling applications, electro-hydrodynamic pumping technology can be used as a means of providing precise control of small amounts of liquid. This has application as an insulin delivery mechanism for diabetics and in the so-called laboratory-on-a-chip

这个小型企业创新研究（SBIR）第二阶段项目将为笔记本电脑开发一种紧凑、重量轻、无噪音的冷却系统。该产品将是一个空气冷却的微通道散热器，通道内集成了一个电流体动力（EHD）泵。研究将集中于开发具有大型平行微通道阵列的散热器，以提供最佳热阻。第二个主要的发展领域将是EHD气流装置;对电晕风技术的修改将用于提供通过散热器的气流。其他任务包括电源开发、系统集成、制造工艺开发和可靠性改进。随着笔记本电脑的速度和性能的提高，微处理器的功率密度也在上升，散热量也在增加。拟议的项目解决了这样一个事实，即膝上型计算机冷却系统将需要耗散40瓦以上，同时保持微处理器低于85摄氏度。商业上，拟议的冷却系统正在开发中，用于不断增长的膝上型计算机市场。2007年将售出2.35亿台个人电脑，其中大约三分之一或约8 000万台将是笔记本电脑。该产品体积小，散热能力强，将使笔记本电脑制造商能够采用更快的处理器，同时减少产品的整体尺寸和重量。除了冷却应用外，电流体动力泵送技术还可以用作对少量液体进行精确控制的手段。这可以应用于糖尿病患者的胰岛素输送机制和所谓的芯片实验室
