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的方法来开发下一代无源冷却解决方案，用于高电池充电器，其中包括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。被动冷却方法在可能的情况下是广泛优选的，因为它们提供了低成本，无寄生力，安静的操作和可靠的解决方案。 **拟议的研究项目建立在过去六个月中Bahrami博士和Delta-Q Technologies博士和Delta-Q Technologies之间的富有成效合作的基础上。 Delta-Q是电池充电器的主要制造商，已发货超过100万个充电器，用于全球电动汽车，高尔夫球车，叉车和航空工作平台的应用。在电池充电器中，输入功率的10-15％用于冷却设备的电子组件。电子设备中的许多故障机制源于过热。该行业的趋势是降低尺寸并增加功率，从而双重影响电池充电器的冷却需求。因此，冷却已成为更高功率密度电池充电器开发的限制因素。 **拟议的热溶液将消除寄生动力消耗，从而大大减少行业碳足迹。研究结果将建立设计工具，将导致Delta-Q前往下一代电池充电器技术的开发。此外，本研究开发的基本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，通风和空调以及冷藏领域。此外，拟议的研究项目将支持在一系列多学科领域（例如能源管理，绿色冷却和设计/原型制作）中对高素质人员的培训。
