| 中文摘要: |
| 动力电池的温度呈非均匀分布，常规等强度冷却的空冷或者PCM热管理技术难以满足动力电池温度均匀性的要求。为了对动力电池进行更好地热管理，课题组基于分形理论与电池温度分布设计了由水泵驱动的3种高效液冷流道，并采用共轭传热模型进行了数值模拟分析。数值模拟研究结果表明：树型流道在获得较好的流动均匀性的同时具有较低的流阻，在相同泵功耗下能够实现较低的压降损失和良好的均温性能。 |

| The temperature distribution of the power battery is non uniform. The conventional air cooling or PCM thermal management technology with equal strength cooling cannot meet the requirements of the temperature uniformity of the power battery. In order to improve the thermal management of power battery, three kinds of efficient liquid cooling channels driven by water pump were designed based on fractal theory and temperature distribution of battery, and the conjugate heat transfer model was used for numerical simulation analysis. The results of numerical simulation show that the tree channel has better flow uniformity and lower flow resistance. At the same pump consumption, it can achieve lower pressure drop loss and better temperature uniformity. |
