提出了一种基于相变浆料和微型通道冷却板的锂离子软包电池模块热管理方法。建立了三维热模型，采用正交矩阵试验法对微通道冷却板的结构进行优化设计，以平衡冷却性能和能耗。模拟结果表明，当质量流量小于3 × 10−4kg s−1时，由20%正十八烷微胶囊和80%水组成的PCS的冷却性能优于纯水、乙二醇溶液和矿物油。对于不同浓度的PCS，如果质量流量超过临界值，其冷却性能比纯水差。当电池最高温度的冷却目标高于309 K时，适当微胶囊浓度的PCS冷却方式与水冷方式相比，能耗优势明显。最后，得到了预测PCS物性参数和流动特性对换热和冷却性能影响的无因次经验公式。仿真结果对基于PCS的电池热管理系统的设计具有指导意义。
In this paper, the thermal management based on phase change slurry (PCS) and mini channel cooling plate for the lithium-ion pouch battery module was proposed. The three-dimensional thermal model was established and the optimum structure of the cooling plate with mini channel was designed with the orthogonal matrix experimental method to balance the cooling performance and energy consumption. The simulation results showed that the cooling performance of PCS consisting of 20% n-octadecane microcapsules and 80% water was better than that of pure water, glycol solution and mineral oil, when the mass flow rate was less than 3 × 10−4kg s−1. For different concentrations of PCS, if the mass flow rate exceeded the critical value, its cooling performance was worse than that of pure water. When the cooling target for battery maximum temperature was higher than 309 K, the PCS cooling with appropriate microcapsule concentration had the edge over in energy consumption compared with water cooling. At last, the dimensionless empirical formula was obtained to predict the effect of the PCS's physical parameters and flow characteristics on the heat transfer and cooling performance. The simulation results will be useful for the design of PCS based battery thermal management systems.
