This project aims to use a systematic approach to develop next-generation passive cooling solutions for high power battery chargers, featuring emerging graphite thermal interface materials (TIM), heat pipes, and new efficient naturally-cooled heat sinks. Passive cooling methods are widely preferred, where possible, since they provide low-cost, no-parasitic power, quiet operation, and reliable solutions. **The proposed research project is built on the foundations of a productive collaboration between Dr. Bahrami and Delta-Q Technologies, on an NSERC ENGAGE Grant in the last six months. Delta-Q is a major manufacturer of battery chargers and has shipped over one million chargers for applications in electric vehicles, golf carts, forklifts, and aerial work platforms worldwide. In a battery charger, 10-15% of the input power is consumed for cooling the electronic components of the device. A number of failure mechanisms in electronic devices stem from overheating. The trend in the industry is to reduce the size and increase the power, which doubly impacts the cooling needs in battery chargers. Therefore, cooling has become a limiting factor in the development of higher power-density battery chargers. **The proposed thermal solutions will eliminate parasitic power consumption, thus significantly reduce the industry carbon footprint. The research results will establish design tools that will lead Delta-Q towards the development of next-generation battery charger technologies. In addition, the fundamental knowledge and engineering design tools developed in this research can be employed for a variety of sustainable and green energy applications, including telecom, electronics and power electronics systems, automotive, heat exchanger, heating, ventilating and air-conditioning, and refrigeration sectors. Additionally, the proposed research project will support training of highly qualified personnel in an array of multi-disciplinary areas, such as energy management, green cooling, and design/prototyping.

该项目旨在使用系统化的方法开发用于高功率电池充电器的下一代被动冷却解决方案，采用新兴的石墨热接口材料(TIM)、热管和新的高效自然冷却散热器。在可能的情况下，被动冷却方法是广泛首选的方法，因为它们提供了低成本、无寄生功率、运行安静和可靠的解决方案。*拟议的研究项目是建立在巴赫拉米博士和Delta-Q技术公司在过去六个月中就NSERC Engage Grant进行的富有成效的合作的基础上的。Delta-Q是电池充电器的主要制造商，已在全球发运了100多万个充电器，用于电动汽车、高尔夫球车、叉车和高空作业平台。在电池充电器中，10-15%的输入功率用于冷却设备的电子元件。电子设备中的许多故障机制都源于过热。行业内的趋势是缩小尺寸和增加功率，这对电池充电器的冷却需求产生了双重影响。因此，冷却已成为更高功率密度电池充电器发展的限制因素。**建议的热解决方案将消除寄生功耗，从而显著降低行业碳足迹。研究结果将建立设计工具，引导Delta-Q走向下一代电池充电器技术的发展。此外，本研究开发的基础知识和工程设计工具可用于各种可持续和绿色能源应用，包括电信、电子和电力电子系统、汽车、热交换器、供暖、通风和空调以及制冷部门。此外，拟议的研究项目将支持培训一系列多学科领域的高素质人员，如能源管理、绿色冷却和设计/原型。
