This Small Business Innovation Research (SBIR) Phase I project will develop a compact, energy-efficient 1U server cooling solution that uses rotating heat sinks, or kinetic heat sinks (KHSs), to provide localized processor cooling while also generating the airflow required to cool peripheral server components. The cooling technology would eliminate all 40 mm case fans currently used in 1U servers and replace the high-impedance processor heat sinks with flow-generating KHSs. The proposed KHS solution has the following advantages over existing technologies: (1) lower flow impedance, since each KHS generates pressure instead of flow impedance; (2) lower power consumption, due to the larger flow-generating blades of KHSs compared to those found in 40 mm axial case fans, combined with the lower server flow impedance; and (3) smaller footprint, since the air mover and heat sink are combined into a single component. Phase I studies will involve component- and server-level computational fluid dynamics (CFD) simulations and experimental validation of both the current state-of-the-art cooling solution and the proposed KHS cooling solution. The goal is to demonstrate 50% reduction in footprint and power consumption compared to the state-of-the-art cooling solution. The broader impact/commercial potential of this project stems from the rising power density and overall power consumption in data centers. With the explosive growth of the ?cloud? there has been exponential growth in data centers, whose electricity consumption is the fastest growing electricity-consuming sector in the U.S. The miniaturization of components has resulted in more heat being generated per unit volume, while smaller product form factors provide less space for coolers to dissipate that heat. Kinetic cooling is an early-stage technology that has the potential to significantly reduce cooling power requirements while using a smaller footprint. There are no commercial KHS cooling solutions in the market presently; consequently, the proposed KHS solution would be the first system designed and sold in this category. The initial target markets for the proposed server cooling system will be brand and whitebox server vendors and system integrators. According to analyst reports, 7.6M server systems were brought online in 2010 and this figure is growing at a CAGR of 4.7%. The total market opportunity is approximately $400-$500M with the potential for providing a return on investment under 30 months.

这项小型企业创新研究（SBIR）I阶段项目将开发一种紧凑，节能的1U服务器冷却解决方案，该解决方案使用旋转散热器或动力学散热器（KHSS），以提供局部处理器冷却，同时还会生成冷却外围服务器部件所需的气流。冷却技术将消除目前1U服务器中使用的所有40毫米箱风扇，并用产生流动的KHS替换高阻力处理器散热器。提出的KHS解决方案比现有技术具有以下优点：（1）较低的流阻抗，因为每个KHS都会产生压力而不是流动阻抗； （2）由于KHSS的流量产生较大，与40毫米轴向箱风扇中的流量产生叶片相比，功耗较低，加上较低的服务器流动阻抗； （3）较小的占地面积，因为将空气流量和散热器组合成单个组件。第一阶段的研究将涉及组件和服务器级计算流体动力学（CFD）模拟以及对当前最新冷却解决方案和提议的KHS冷却解决方案的实验验证。与最先进的冷却解决方案相比，目标是证明足迹和功耗的50％。该项目的更广泛的影响/商业潜力源于数据中心的功率密度和整体功耗。随着？云的爆炸性增长？数据中心的指数增长，其电力消耗是美国增长最快的电力耗电领域，其小型成分的小型化导致每单位体积产生更多的热量，而较小的产品形式为冷却器提供了较小的空间来使冷却器耗散热量。动力学冷却是一种早期技术，有可能在使用较小的足迹的同时显着降低冷却能力需求。目前市场上没有商业KHS冷却解决方案；因此，拟议的KHS解决方案将是该类别中设计和出售的第一个系统。建议的服务器冷却系统的初始目标市场将是品牌和白框服务器供应商和系统集成商。 根据分析师的报告，2010年在网上启动了760万服务器系统，该数字的复合年增长率为4.7％。 总市场机会约为400亿美元，有可能在30个月内提供投资回报率。
