项目摘要

The Small Business Technology Transfer Research (STTR) Phase I project aims at developing a heat exchanger technology utilizing a homogeneous nano-porous surface (NPS) that will significantly increase the efficiency of the boiling process. The NPS technology offers considerable enhancement in boiling heat transfer capabilities for small- to large-size heat generating facilities, power plants, and electronics cooling hardware. The goals of the proposed Phase I research are: 1) to develop an effective NPS for boiler applications, 2) to demonstrate the effectiveness of the NPS technology against other conventional heat exchanger technologies, and 3) to evaluate the long-term performance of the NPS based heat boiler. A prototype multi-tube boiler will be constructed and tested for industrial deployment.The objectives of the proposed project will be achieved by producing a surface that can generate smaller and controllable bubble sizes during boiling processes. Unlike traditional flat surfaces and previously investigated micro-porous surface coatings, the NPS technology can offer improved long-term durability, a simple-to-manufacture and low-cost means of achieving higher performance and more energy efficient heat transfer. Successful implementation of this technology will result in millions of dollars saved nationally and internationally in the energy market.

小企业技术转让研究（STTR）第一阶段项目旨在开发一种利用均匀纳米多孔表面（NPO）的热交换器技术，该技术将显着提高沸腾过程的效率。该技术为小型到大型的发热设施、发电厂和电子冷却硬件提供了相当大的沸腾传热能力增强。拟议的第一阶段研究的目标是：1）开发一种有效的锅炉应用，2）证明与其他传统热交换器技术相比，热交换器技术的有效性，以及3）评估基于热交换器的热锅炉的长期性能。将建造一个多管锅炉原型，并进行测试，以供工业部署。拟议项目的目标将通过制造一个表面来实现，该表面可以在沸腾过程中产生更小和可控的气泡尺寸。与传统的平面和先前研究的微孔表面涂层不同，该技术可以提供更好的长期耐用性，制造简单，成本低，实现更高的性能和更节能的热传递。该技术的成功实施将为国内和国际能源市场节省数百万美元。
