摘要:

有效的热管理对于燃料电池汽车(fuel cell vehicles,FCV)的高效运行至关重要。燃料电池汽车热管理多采用各子系统独立管理方式,然而这种独立的方式并不能很好地利用自身余热从而提高热管理效率和续航里程。对此,本文开发了一种利用燃料电池余热的整车集成式热管理(vehicle integrated thermal management,VITM)系统,采用热交换器进行一体化的VITM,实现燃料电池的余热回收和各部件高效的热管理,通过六通阀的集成设计实现各回路解耦的灵活管理。并在AMESim仿真平台上开展热管理的仿真研究。结果表明:本文开发的VITM系统能保持燃料电池汽车各部件稳定维持在规定的工作温度范围内;在-10 ℃的环境温度下,利用燃料电池余热作为热源的热泵空调给动力电池加热,与直接加热模式相比,加热时间缩短55%;给乘员舱加热的时间缩短85%,且能耗比(coefficient of performance,COP)值为4,能耗降低75%。

Abstract:

Effective thermal management is crucial for the efficient operation of fuel cell vehicles (FCVs). Fuel cell vehicle thermal management often adopts independent management methods for each subsystem, but this independent method cannot effectively utilize its own waste heat to improve thermal management efficiency and range. In this regard, a vehicle integrated thermal management (VITM) system that utilizes fuel cell waste heat is developed in this paper. The VITM uses a heat exchanger to achieve waste heat recovery of fuel cells and efficient thermal management of various components. The flexible management of each circuit decoupling is achieved through the integrated design of six-way valves. And simulation research on thermal management is conducted on the AMESim simulation platform. The results show that the VITM system developed in this paper can maintain the stability of various components of fuel cell vehicles within the specified operating temperature range. At an ambient temperature of -10 ℃, compared with direct heating mode, a heat pump air conditioner using fuel cell waste heat as a heat source to heat the power battery, the heating time is reduced by 55%.The heating time for the passenger compartment is reduced by 85%, and the energy consumption ratio (COP) value is 4, resulting in a 75% reduction in energy consumption.
