摘　　要：随着电动汽车动力电池能量密度和快充倍率的提高,为了满足散热的要求,电池的液冷系统应用越来越广泛。作为液冷系统中的核心部件,液冷板的重要性日益凸显。文章利用了铝合金挤压型材中的空腔可以作为冷却液流道这一特点,设计了一种单元液冷板,单元液冷板之间通过搅拌摩擦焊进行拼接组成整体液冷板,整体液冷板进液管路和出液管路采用尼龙波纹管.通过对三种不同的管路布设方式进行系统压差和流量的对比分析,得出三级进液方式的压降和流量一致性较好的结论。With the improvement of energy density and fast charge rate of electric vehicle power battery,in order to meet the requirements of heat dissipation,the liquid cooling system of battery is more and more widely used.As the core component of liquid cooling system,the importance of liquid cooling plate is increasingly prominent.In this paper,a kind of liquid cooling plateunit is designed using that the cavity of aluminum alloy extrusion profile can be used as the coolant flow channel.The liquid cooling plate units are spliced by friction stir welding to form a whole liquid cooling plate,the inlet and outlet pipes of the whole liquid cooling plate consist of nylon bellows.Through the comparative analysis of the pressure drop and flow of three different methods for the pipeline layout,it is concluded that the pressure drop and flow consistency of the three-stage feeding mode is preferable.
