- 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.
