Design and Investigation of the Performance of a Self-driven Cooling System for Hydrogen Fuel Cells
氢燃料电池的发展对实现清洁能源转型、减少碳排放和提高能源利用效率具有至关重要的作用,是推动可持续发展的关键技术之一.氢燃料电池在设计温度范围内工作可以达到其最佳运行性能,而高效的热管理系统则是控制电池运行温度在设计温度范围内的关键.因此,在传统氢燃料电池结构的基础上,在其内部添加强化换热的微通道结构,并结合环路热管可以驱动流体工质在其内部循环的原理,设计一种高效的自适应热管理系统,通过实验验证该系统散热的可行性并初步实现了自适应散热.实验结果显示,系统内产生了可以随热源功率增加而升高的流体工质循环流量,电池中的微通道换热结构具有0.02 K/W的低换热热阻,实现了最高约100 W的散热功率和30 W/cm2的散热热流密度.该系统同时结合了环路热管和微通道的高效换热特点,并实现自驱动和自适应特性,为氢燃料电池的节能、可靠且有效散热提供了新的思路.
The development of hydrogen fuel cells plays a crucial role in achieving the transition to clean energy,reducing carbon emissions,and improving energy efficiency.It is one of the key technologies driving sustainable development.Hydrogen fuel cells operate at their optimal performance within a specific temperature range,and an efficient thermal management system is essential to maintain the battery's operating temperature within this range.Therefore,a high-efficiency adaptive thermal management system based on the traditional hydrogen fuel cell structure is proposed in this paper.The system integrates a microchannel structure to enhance heat transfer within the cell and combines the principles of a loop heat pipe,which can drive the working fluid to circulate within.The experiments demonstrate the feasibility of the proposed system for heat dissipation and preliminarily realize adaptive heat dissipation.The experimental results show that the system generates a circulation flow of the working fluid that increases with the power of the heat source.The microchannel heat transfer structure in the cell exhibits a low thermal resistance of 0.02 K/W,achieving a maximum heat dissipation power of approximately 100 W and a heat flux density of 30 W/cm2.The system combines the high-efficiency heat transfer characteristics of the loop heat pipe and microchannel,realizing self-driving and adaptive features,providing a new approach for energy-saving,reliable,and effective heat dissipation in hydrogen fuel cells.
