This SBIR Phase I research project will demonstrate the feasibility of designing a solid state fan with performance characteristics that are superior to the conventional, rotating blade fans or centrifugal blowers that are typically used in conjunction with heat sinks. The goal is to develop an ion-drag type fan that is lower in cost, noiseless, an order of magnitude smaller in size and weight, more energy efficient and more reliable as compared to the standard axial fan or centrifugal blowers. A unique ion generation mechanism called self seeding electrodes will be evaluated. This will be done by modeling the mechanism and verifying the model with experiments. The fluid flow, heat transfer and dust tolerance capabilities of the new mechanism will also be evaluated.The waste heat load produced by personal computers and consumer electronics continues to increase with a simultaneous decrease in overall product dimensions. This trend is straining the capabilities of conventional, air cooled heat sinking products. The impact of this new heat transfer technology will be in the area of mobile computing. The solid-state fan will enable laptop computers to further shrink in size while maintaining their performance. It will enable ultra-slim and even ultra-mobile computers (palm sized computers) to run full featured versions of operating systems and other PC software and perform at a similar level to their larger counterparts.

该SBIR第一阶段研究项目将证明设计一种性能特性上级传统旋转叶片风扇或通常与散热器结合使用的离心式鼓风机的固态风扇的可行性。目标是开发一种离子拖曳型风扇，与标准轴流式风扇或离心式鼓风机相比，该离子拖曳型风扇成本更低、无噪音、尺寸和重量小一个数量级、更节能且更可靠。一个独特的离子产生机制称为自播种电极将进行评估。这将通过建立机理模型并通过实验验证模型来完成。此外，还将对新装置的流体流动、传热和防尘能力进行评估。个人电脑和消费电子产品产生的废热负荷持续增加，同时产品整体尺寸也在缩小。这一趋势使传统的风冷散热产品的能力变得紧张。这种新的传热技术的影响将在移动的计算领域。固态风扇将使笔记本电脑在保持性能的同时进一步缩小尺寸。它将使超薄，甚至超移动计算机（掌上电脑）运行操作系统和其他PC软件的全功能版本，并在类似的水平上执行其较大的同行。
