摘要: 集成模块化热管理系统在减少系统体积和降低能耗方面具有显著优势,已成为电动汽车热管理发展的主要方向。传统电动汽车的热管理系统主要采用零部件紧凑布局并辅以短管路连接的方式,热管理系统体积较大,且系统流动阻力大。为此,提出了一种集成模块化的整车热管理系统设计,包括制冷剂模块与冷却液模块结构,并对其热管理的工作原理进行了研究。随后,开展制冷剂与冷却液模块在不同工况下流阻与串热量的仿真分析,结果显示制冷剂模块的最大流阻值为75 kPa,冷却液模块电机回路的最大流阻值为16.6 kPa,电池回路流阻最大值为17.3 kPa,验证了集成模块化热管理系统能有效降低流动阻力。随后,完成了集成模块化热管理系统的样机制造,并搭建了测试平台对其性能进行测试。试验结果表明集成模块化热管理系统在不同工况下的能效比系数均大于2.5,且制冷模式热平衡工况下能效比系数达3.5,验证该系统的低能耗优势和应用潜力。

Abstract: The integrated modular thermal management system significantly reduces system volume and energy consumption, becoming a major development focus in electric vehicle (EV) thermal management technologies. Traditional EV systems use compact layouts with short piping, which do not effectively reduce volume and result in high flow resistance. This paper presents an integrated modular thermal management system incorporating a refrigerant and a coolant module, and examines their thermal management principles. Simulation of flow resistance and heat transfer under various operating conditions show that the maximum flow resistance of the refrigerant module is 75 kPa, while for the coolant module the motor circuit has a maximum resistance of 16.6 kPa, and the battery circuit has a maximum resistance of 17.3 kPa, validating the rationality of the system design. Then, a prototype of the integrated modular thermal management system was built, and a testing platform was established to evaluate its performance. Experimental results indicate that the coefficient of performance of the system is above 2.5 under different operating conditions, reaching 3.5 under thermal equilibrium in cooling mode, validating its energy efficiency and promising application potential.
