description | The safety design of battery thermal management system is an important guarantee to keep the best working temperature range and uniform temperature distribution of battery module. Based on the geometrical structure characteristics of spider web, a battery thermal management system with bionic flow channel structure is designed and applied to cylindrical lithium battery module.The computational fluid dynamics model of the battery module is established, and the influence of different flow channel structure parameters and inlet velocity on the thermal performance of the thermal management system is investigated. The results show that the height of the flow channel structure is the most important factor affecting the thermal performance of the battery thermal management system. At an inlet rate of 0.4 g/s and at a discharge rate of 2C, the optimum structural parameters are calculated to maintain the maximum battery temperature, maximum temperature difference and pressure drop at 302.972 K, 3.858 K and 22.75 Pa, respectively.The spider web-like structure of the thermal management system can effectively reduce the power consumption of the electronic water pump, which is beneficial to the long range of electric vehicles, and its pressure drop is reduced by more than 60% compared to the honeycomb-like structure for the same flow channel structure parameters. |
