SBIR Phase II: Innovative Two-Phase High-Heat-Flux Heat Exchanger

这个小型企业创新研究（SBIR）二期项目旨在展示一种创新的多相流体热交换器，能够彻底改变高热流密度冷却应用的传热。初步实验证实，在相同流速下，亚稳态两相流体的换热系数比单相流体高40%，并且具有耗散热流密度值的潜力。该技术的广泛影响/商业潜力将导致标准化的两相冷板系列，可被电子设备的设计人员用于各种应用。新的两相冷板系列将以与现有风冷设备相似的尺寸和配置出售，但将显着增加热流通量耗散率并降低热阻。该项目还将提供辅助设计信息和交互式设计工具，供电气包装设计师使用。然后，设计师将根据基本的蒸汽压缩设计原则自由地包装热管理系统的其余部分或购买系统。此外，对于标准热组件不能工作的应用，该项目将提供定制解决方案。

This Small Business Innovation Research (SBIR) Phase II project aims to demonstrate an innovative multi-phase-fluid heat exchanger capable of revolutionizing heat transfer for high-heat-flux cooling applications. Initial experiments confirmed that metastable two-phase fluids can produce heat transfer coefficients 40% greater than single-phase fluids at the same flow rate and they have the potential to dissipate heat flux values. The broader impact/commercial potential from the technology will be result in a standardized family of two-phase cold plates that can be used by designers of electronics devices for a wide variety of applications. The new family of two-phase cold plates will be sold in sizes and configurations similar to existing air-cooled devices, but will have significantly increased heat flux dissipation rates and reduced thermal resistances. This project will also provide supporting design information and an Interactive Design Tool for use by the electrical packaging designer. The designer will then be free to package the remainder of the thermal management system based on basic vapor-compression design principals or purchase a system. Additionally, for applications where standard thermal components will not work, this project will provide custom solutions.
