氢燃料电池自驱动散热系统设计及性能探究
Design and Investigation of the Performance of a Self-driven Cooling System for Hydrogen Fuel Cells
摘要
Abstract
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.关键词
