The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is that it enables significantly enhanced cooling performance for consumer and embedded electronics of mobile devices in the worldwide race for more efficient products. Compared with the current state of the art, this project’s micro Closed-Loop Pulsating Heat Pipes (CLPHPs) will provide over 40% higher cooling capacity, increase battery life by more than 30%, and reduce electricity consumption by over 25%. It will be made of a recyclable material (aluminum) or ceramic with a new environmentally friendly working fluid inside. The primary source of revenue will be via product sales of CLPHP-based heat sinks to laptop OEMs and other OEMs, integrators, and end users. We anticipate entering the market in 2026/2027 for mainstream and gaming “thin and light” laptops and electronics with discrete GPUs and CPUs/processors requiring advanced cooling. CLPHPs provide a direct replacement for existing vapor chamber, heat pipe, and heatsink solutions for these devices. The main deliverable is to develop an industry-leading heat spreader- that operates passively, creating its coolant flow from its self-pulsating mechanism, critical for thin mobile electronics for which fans or other auxiliary powered non-passive solutions are avoided. This SBIR Phase II project proposes to address the urgent cooling challenges presented by next-generation 5G/6G mobile devices and other advanced electronics (Artificial Intelligence, Internet of Things) for which a solution has yet to be found. The objectives are to build on the fundamental and practical knowledge developed in the Phase I project to geometrically enhance the micro-channels to increase the internal surface area, the evaporation and condensation processes, and the flow rate to achieve even greater heat-spreading capability. This will be accomplished through fabricating and testing two novel CLPHP designs (generations 2 and 3) under various heating conditions and orientations representative of mobile device applications. The goal is to enter the market with this disruptive cooling technology that will enhance the performance of millions of mobile devices, save battery/grid energy, and unlock the barriers created by today’s lack of advanced cooling solutions. The novel CLPHP is an important “enabler” of numerous new devices yet to be conceived and for improvement of existing advanced technologies, nearly all of which are electronically “throttled” by the limiting performance of current cooling technologies. This project is well-positioned to provide the US/worldwide market with the needed cooling solutions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力是，它可以在全球竞赛中为消费者和移动设备的嵌入式电子设备提供显着提高冷却性能，以获得更高效的产品。与当前的最新状态相比，该项目的微环脉动热管（CLPHP）将提供高40％以上的冷却能力，将电池寿命提高30％以上，并将电力消耗降低25％以上。它将由可回收材料（铝）或陶瓷制成，内部有一种新的环保工作液。收入的主要来源将是通过基于CLPHP的散热器的产品销售向笔记本电脑OEM和其他OEM，集成商和最终用户的销售。我们预计将在2026/2027进入市场，以使用离散的GPU和CPU/CPU/处理器进行高级冷却的主流和游戏“薄和轻”笔记本电脑和电子产品。 CLPHP可直接替换这些设备的现有蒸气室，热管解决方案。主要的交付是开发一个行业领先的热量散布器，该热量被动地运行，从其自动化机制产生冷却液流量，这对于避免风扇或其他辅助驱动的非辅助溶液的薄移动电子设备至关重要。这项SBIR II期项目提案旨在解决下一代5G/6G移动设备和其他高级电子设备（人工智能，物联网）提出的紧急冷却挑战，尚未找到解决方案。这些目标是建立在第一阶段项目中开发的基本和实践知识的基础上，以几何增强微通道，以增加内部表面积，经济和凝结过程以及流量，以达到更大的热量功能。这将通过在代表移动设备应用的各种加热条件和方向下制造和测试两种新型CLPHP设计（几代和第3代）来实现。目的是通过这种破坏性的冷却技术进入市场，该技术将增强数百万移动设备的性能，节省电池/电网能源，并解锁当今缺乏高级冷却解决方案所产生的障碍。新颖的CLPHP是尚未构想的许多新设备的重要“推动器”，并且用于改进现有的先进技术，几乎所有这些都通过当前冷却技术的限制性能在电子上“限制”。该项目的位置良好，可以为美国/全球市场提供所需的冷却解决方案。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被视为通过评估而被视为珍贵的支持。
