摘要
基于某燃料电池乘用车的热管理系统模型,计算了该乘用车在匀速、加速、爬坡和不同环境温度下的整车热管理系统的工作特性。可以看出:燃料电池工作温度低、热负荷大,热管理系统无法在全工况满足燃料电池系统散热的需求。在现有的热管理技术条件下,可通过提高燃料电池的工作温度、增加迎风空气流量等方法来增加整车热管理系统的散热量。
Based on the thermal management system model for a fuel cell car,the working characteristics of its thermal management system in different working conditions（constant speed cruising,accelerating and slope climbing） and different ambient temperatures are calculated.It can be seen from the results that due to the low operating temperature and heavy thermal load of fuel cell,the thermal management system cannot meet the heat dissipation requirements of fuel cell system in all operating conditions.Under existing thermal management technical condition,the heat dissipated in vehicle thermal management system can be increased by raising the operating temperature of fuel cell and head-on air flow.
