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。

Abstract: 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.

Key words: phase change material, tubular, simulation, thermal resistance, battery thermal management, forced convection heat transfer
