摘要： 为将储能电池包使用温度控制在理想范围内，选取多流道蛇形液冷板作为电池包的液冷系统，分析液冷板流道数量对冷却效率的影响。采用流道数量为3、4、5、6、7、8共6种设计方案，发现液冷板流道数量对换热性能的影响不明显，所有液冷板均能使电池包最高温度保持在39 ℃以下，平均温度为34.3 ℃左右，各电芯温差保持在2.1 ℃左右，使电池包处于正常工作的温度范围内，液冷板流动阻力会随着流道数量的增加而降低。综合对比液冷板流动阻力与加工难度选取5流道液冷板做参数优化，确保其冷却性能不受影响的情况下，将流动阻力从1 101 Pa减小到640.6 Pa，降低液冷系统能耗，提高效率。

Abstract: In order to control the service temperature of energy storage battery pack in an ideal range, a multi-channel serpentine liquid cooling plate is selected as the liquid cooling system of battery pack, and the influence of the number of channels of liquid cooling plate on cooling efficiency is analyzed. Six design schemes with the number of flow channels of 3, 4, 5, 6, 7 and 8 were adopted. It was found that the number of flow channels of liquid-cooled plates had no obvious influence on the heat transfer performance. All liquid-cooled plates could keep the maximum temperature of the battery pack below 39 ℃, with the average temperature of 34.3 ℃, and the temperature difference between cells was around 2.1 ℃, so that the battery pack was in the normal working temperature range, and the flow resistance of liquid-cooled plates would decrease with the increase of the number of flow channels. By comprehensively comparing the flow resistance and processing difficulty of liquid cooling plate, the five-channel liquid cooling plate is selected for parameter optimization, and the flow resistance can be reduced from 1 101 Pa to 640.6 Pa without affecting its cooling performance, thus reducing the energy consumption of liquid cooling system and improving efficiency.
