摘　　要：设计了一种新型的管状复合相变材料(tubular Composite PCM,t-CPCM)结构,用以替代传统的块状复合相变材料(block-shaped Composite PCM,b-CPCM)结构,将其耦合强制对流换热后应用于电池热管理。仿真结果表明,相比于b-CPCM电池仿真模型,t-CPCM电池仿真模型不仅流道分布更加均匀,而且对流换热面积更大,理论计算得出的对流换热热阻仅为0.8 K·W^(−1),是b-CPCM电池仿真模型的1/20。实验结果表明,t-CPCM电池模组优异的散热性能可以有效地控制电池温度,t-CPCM电池模组的最高温度仅为46.9℃,温差为0.8℃;而b-CPCM电池模组的最高温度高达51℃,温差均为5℃。所设计的管状复合相变材料在电池热管理方面具有良好的应用价值。A new type of tubular composite phase change material(t-CPCM)structure is designed to replace the traditional block-shaped composite phase change material(b-CPCM)structure,coupled with forced convection heat transfer and applied to battery thermal management.The simulation results show that,compared with the b-CPCM model,the t-CPCM model not only has a more uniform flow channel distribution,but also a larger convective heat transfer area.The theoretically calculated convective heat transfer thermal resistance is 0.8 K·W^(−1),which is 20 times less than b-CPCM model.The experimental results show that the excellent heat dissipation performance of the t-CPCM battery module can effectively control the battery temperature.For example,the maximum temperature of the t-CPCM battery module is 46.9℃,and the temperature difference is only 0.8℃;as for the b-CPCM battery module,the highest temperature is as high as 51℃,and the temperature difference is 5℃.The designed t-CPCM has important application value in battery thermal management.
