摘要:
在特种车辆复杂工况下的运行过程中，电池过热问题是制约其性能与安全性的关键因素之一。基于动静脉毛细血管具有营养物质输送能力的启发，设计了一种新型血管仿生流道结构，利用计算流体力学数值计算方法对电池模组进行瞬态模拟，并借助试验平台对仿真模型进行初步验证，实现不同结构方案的对比分析，深入探究液冷板散热效果及压力损失与结构参数、冷却介质、放电倍率和环境温度之间的关联特性，并基于正交试验实现液冷板结构优化设计。结果表明：新型流道相较于平行流道结构，其散热性能得到有效提升，压力损失降低40.7%；冷却介质的物性参数直接影响着其散热性能和压力损失，质量流量入口流速增加可提升冷板散热效果，在流速30 L/min后随着持续增加改善效果受限；在38 ℃至70 ℃工作环境温度下，电池模组最高温度在45 ℃上下，表面温差小于2 ℃，均处于合理范围内。本研究有助于推动不同环境下特种车辆电池热管理技术的应用，为提高电池包温度均匀性和冷却速率、降低能耗的研究提供数据支撑。
Abstract:
The issue of battery overheating is one of the key factors limiting the performance and safety of special vehicles operating under complex conditions. To address this, inspired by the nutrient delivery capabilities of arterial and venous capillaries, this paper designs a novel vascular biomimetic flow channel structure. Using computational fluid dynamics (CFD) numerical simulation methods, transient simulations of the battery module are conducted, and a preliminary validation of the simulation model is performed using an experimental platform. This allows for a comparative analysis of different structural schemes and an in-depth exploration of the relationship between the heat dissipation effect of the liquid-cooled plate, pressure loss, structural parameters, cooling media, discharge rates, and environmental temperatures. And based on orthogonal experimental design, an optimized design of the liquid-cooled plate structure was achieved. The results indicate that the novel channel structure significantly enhances cooling performance compared to parallel channel structures, achieving a 40.7% reduction in pressure loss. The physical properties of the cooling medium directly affect its cooling performance and pressure loss, and increasing the inlet flow rate of the mass flow improves the cooling effect of the cold plate, though the improvement becomes limited after a flow rate of 30 L/min. Under working environment temperatures ranging from 38℃ to 70℃, the maximum temperature of the battery module remains around 45℃, with a surface temperature difference of less than 2℃, all within a reasonable range. This study contributes to advancing the application of battery thermal management technology in special vehicles under various environmental conditions, providing data support for research aimed at improving battery pack temperature uniformity and cooling rates while reducing energy consumption.
