【摘要】：车用燃料电池系统发电的同时释放大量热量,必须构建适合的热管理系统以确保系统性能和可靠性。在分析车用燃料电池热管理系统工作原理基础上,建立了面向控制的计及电堆、空气冷却器、氢气热交换器、旁路阀、散热片和冷却水循环泵模型的燃料电池热管理系统模型,并通过仿真实验研究了电堆电流、冷却液流速、散热片表面风速、旁路阀开度与燃料电池温度的关系;讨论了它们对空气冷却器、氢气热交换器、电堆及散热器入口与出口温度差的影响。模拟结果可以为燃料电池热管理控制系统设计提供指导和帮助。
[Abstract]:A suitable thermal management system must be constructed to ensure the performance and reliability of the vehicle fuel cell system, which can generate electricity and release a lot of heat at the same time. Based on the analysis of the working principle of the fuel cell heat management system for vehicle, a fuel cell heat management system model is established, which takes into account the models of electric reactor, air cooler, hydrogen heat exchanger, bypass valve, heat sink and cooling water cycle pump. The relationship between stack current, flow rate of coolant, surface wind speed of radiator, opening of bypass valve and fuel cell temperature is studied by simulation, and their effects on air cooler and hydrogen heat exchanger are discussed. Effect of temperature difference between inlet and outlet of stack and radiator. The simulation results can provide guidance and help for the design of fuel cell thermal management and control system.
