摘要
随着液冷式预制舱储能推广,亟需冷却液回路设计方法。从工程实用角度出发,针对液冷板,提出了普适于常见3至4排电芯电池包的U形流道结构,分析了流道宽度、高度设计方法;针对液冷管路,提出管路并联式排布和管路变径的方案,阐述了管路流量、节流孔尺寸设计方法。依托1 MW/2 MWh海岛储能工程,分析了工程设计实例。收集并分析了现场运行情况,所设计方案能将电池温度控制至预定区间,电池温差不超过3℃。
With the promotion of liquid-cooled prefabricated cabin energy storage systems,a design method for coolant piping is urgently needed.From a practical perspective,a U-shaped-channel cooling plate suitable for battery packs containing 3~4 battery rows is proposed,and the design methods for channel width and height is analyzed;parallel pipeline arrangement and pipeline diameter gradation are proposed.Pipeline flow and throttle size design method is described.A design example for a 1 MW/2 MWh island energy storage project is analyzed.The on-site operation are analyzed.The design scheme can drive the battery temperature to the anticipated range,and the battery temperature difference does not exceed 3℃.
