0846318da SilvaThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This research seeks to develop a new class of bio-inspired, single phase liquid cooling systems for application in three-dimensional integrated circuitry. The novel features of the research are twofold: (i) use of coolant flow channel patterns commonly found in natural systems, coupled with (ii) real-time self-adjusting complexity of the bio-inspired coolant flow path. The latter feature is enabled by the use of temperature sensitive shape memory shape alloys to construct micro regulators within the flow channels that adjust to local temperatures and redistribute the coolant. Intellectual Merit: Bio-inspired flow paths, which will have hydraulic diameters on the order of 500 microns, will be etched into a silicon wafer. Various microfabrication steps will be used to ultimately embed nickel-titanium flow regulators into the silicon substrate. These small regulators will open or close in response to local temperatures and dynamically control the flow path of the coolant through the flow channel matrix. Measurements, conducted with a unique experimental apparatus, will be made in order to determine the ability of the temperature sensitive gates to respond to and control local temperatures. The experimental study will be complemented by a numerical investigation including simulation of the coupled dynamic response of the flow regulators to varying temperature and coolant flow distributions.Broader Impacts: The proposed approach may enable new approaches to efficiently cool integrated circuitry to allow operation over a wider range of conditions while minimizing coolant pumping power requirements. Outreach activities will include underrepresented students from K-12, K-14, K-16 and K-20 levels on project related tasks. The Adopt a Mentee Program (AMP) developed by the PI facilitates partnering students at a given educational level with students at advanced levels who become their mentors. The AMP will be administered by the PI with support provided by the Equal Opportunity in Engineering program of School of Engineering at The University of Texas at Austin. Recruitment of students for AMP will be through a new seminar-based program, You Can Too, where underrepresented students can meet and interact with undergraduate and graduate student role models who had to overcome major obstacles to pursue their engineering education. A new course entitled Bio-Inspired Transport Phenomena Systems will also be developed. Finally, the PI will participate in the ASME Central Texas Chapter and the UT Explore Weekend as a speaker, volunteer and mentor.

0846318 da Silva该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该研究旨在开发一种新型的生物启发，单相液体冷却系统，用于三维集成电路。该研究的新特点有两个方面：（i）使用自然系统中常见的冷却剂流动通道模式，以及（ii）实时自调节生物启发冷却剂流动路径的复杂性。后一个特点是通过使用温度敏感的形状记忆合金在流动通道内构建微调节器来调节局部温度并重新分配冷却剂。智力优点：生物启发的流动路径，将有水力直径约500微米，将蚀刻到硅晶片。各种微加工步骤将被用来最终嵌入镍钛流量调节器到硅基板。这些小型调节器将响应于局部温度而打开或关闭，并动态地控制冷却剂通过流动通道矩阵的流动路径。将使用独特的实验装置进行测量，以确定温度敏感门响应和控制局部温度的能力。实验研究将补充的数值调查，包括模拟的耦合动态响应的流量调节器，以不同的温度和冷却剂流量distribution.Broader的影响：所提出的方法可以使新的方法来有效地冷却集成电路，允许在更广泛的条件下运行，同时最大限度地减少冷却剂泵送功率的要求。外联活动将包括来自K-12，K-14，K-16和K-20级别的代表性不足的学生，他们将参与项目相关任务。PI制定的“接纳一名辅导员方案”促进了某一教育水平的学生与成为其辅导员的高级学生结成伙伴关系。AMP将由PI管理，并由德克萨斯大学奥斯汀分校工程学院工程平等机会计划提供支持。AMP的学生招聘将通过一个新的基于校园的计划，你也可以，在那里代表性不足的学生可以满足和互动与本科生和研究生的榜样谁必须克服重大障碍，以追求他们的工程教育。还将开发一门题为“生物启发的运输现象系统”的新课程。最后，PI将作为演讲者，志愿者和导师参加ASME德克萨斯州中部分会和UT探索周末。
