为了解冷板式液体冷却技术和浸没式液体冷却技术的性能差异，以市场上常见配置的储能用电池模组为对象，分别建立冷板式冷却和浸没式冷却的数值模型，通过仿真分析方法评估这2种技术在不同放电倍率条件(0.5C、1C、2C)下的性能差异。结果表明：在相同放电倍率条件下，采用浸没式冷却的电池模组的最高温度和最大温差总是优于采用冷板式冷却的电池模组，且最大温差的降低幅度会随着放电倍率的提升而更加明显；采用冷板式冷却的电池模组温度场分布存在明显分层现象，模组内部单体电池上存在极大温度梯度，而采用浸没式冷却的电池模组温度场分布均匀，内部单体电池上不存在明显的温度梯度；采用冷板式冷却的电池模组压降远大于采用浸没式冷却的电池模组。
Abstract：In order to understand the performance differences between the cold plate liquid cooling technology and the immersion liquid cooling technology, taking commonly configured energy storage battery module on the market as the subject, numerical models for both cold plate cooling and immersion cooling are established respectively. Through simulation analysis method, the performance differences between the two technologies are evaluated under different discharge rates(0.5C, 1C, 2C). The results show that under the same discharge rate, the maximum temperature and the maximum temperature difference of the battery module using immersion cooling are always superior to the battery module using cold plate cooling, and the reduction in the maximum temperature difference becomes more pronounced with increasing discharge rates. The temperature distribution in the battery module using cold plate cooling behaves a significant stratification, with extreme temperature gradients across individual batteries within the module, while the temperature distribution in the battery module using immersion cooling is uniform, with no significant temperature gradients across individual batteries. The pressure drop in the battery module using cold plate cooling is much greater than that in the battery module using immersion cooling.
