摘　　要：本文针对某新能源汽车动力电池模组液冷板流道结构,设计了纵/横弓型两种流道结构,运用有限元软件对液冷板进行散热仿真研究。结果表明,横弓型流道较纵弓型流道的拐角减少,流场更加均匀,液冷循环更有效地带走电池模组热量,横弓型电池模组比纵弓型电池模组整体温度下降了2.59℃,散热效果良好。研究结果为液冷板流道设计、动力电池散热研究提供依据。This article focuses on the flow channel structure of the liquid cooling plate of a certain new energy vehicle power battery module,and designs two types of flow channel structures:longitudinal and transverse bow.Finite element software is used to conduct heat dissipation simulation research on the liquid cooling plate.The results showed that the corners of the transverse bow channel were reduced compared to the longitudinal bow channel,the flow field was more uniform,and the liquid cooling cycle was more effective in carrying away the heat of the battery module.The overall temperature of the transverse bow battery module decreased by 2.59℃ compared to the longitudinal bow battery module,and the heat dissipation effect was good.The research results provide a basis for the design of liquid cooled plate flow channels and the study of power battery heat dissipation.
