针对储能电池液冷板散热不均导致的电芯温度过高问题,采用计算流体力学 (computational fluid dynamics,CFD)方法,对液冷板流道结构、流道内翅片布置方式和液冷策略进行优化研究,从而提升液冷板的散热性能,改善电芯内部热温度分布均匀性。将液冷板流道由初始的单进单出结构,通过增加进出口数量和改变进出口位置,变成双进双出的双流道结构;在流道内增加扰流翅片,以提升液冷性能;采用正交模拟方法,研究圆形翅片在流道内布置的横向距离(

,该组合下电芯最高温度、平均温度比未布置翅片时分别降低0.33,0.40 ℃;采用变流量液冷策略使电芯在放电第二阶段、第三阶段的流道压降分别降低34.79%、13.19%。
To address the issue of excessive temperature in battery cells caused by uneven heat dissipation of liquid cooling plates, computational fluid dynamics (CFD) methods are employed to optimize the structure of the liquid cooling plate’s flow channels, the arrangement of the find within the channels, and the liquid cooling strategies to enhance the heat dissipation performance of the liquid cooling plate and improve temperature uniformity of the battery cells. The flow channel of the liquid cooling plate is transformed from an initial single inlet and outlet structure to a dual inlet and outlet dual-channel structure by increasing the number of inlets and outlets and changing their positions. Turbulence fins are added within the channels to enhance cooling performance. Using orthogonal simulation methods, the lateral distance (
a
), longitudinal distance (
b
), and height (
h
) of circular fins in the channel are studied for their impact on the maximum and average temperature of the battery cells, thereby determining the optimal arrangement of the fins. To achieve the same cooling effect as a constant flow liquid cooling strategy while reducing the energy consumption of the liquid cooling plate, a variable flow liquid cooling strategy implemented to achieve pressure drop in the channels. Results indicate that compared with the initial structure, the dual inlet liquid cooling plate reduces the maximum temperature of the liquid cooling plate by 0.72 ℃; the height of the fins has the greatest impact on the heat dissipation of the liquid cooling plate; the optimal parameter combination for orthogonal arrangement is

, under which the maximum and average temperatures of the batter
y cells decrease by 0.33 ℃ and 0.40 ℃, respectively, compared to when no fins are arranged; the variable flow liquid cooling strategy leads to pressure drops in the channels during the second and third discharge phases, reduced by 34.79% and 13.19%, respectively.
