To investigate the impact of structural optimizations on the heat dissipation of lithium batteries.
Established a thermal model and computational fluid dynamics control equations.
Designed a thermal management system with a bionic leaf vein flow channel.
Examined effects of flow passage configurations, flow channel angles, widths, flow rates, and inlet-outlet positions on cooling.
Battery cooling effect worsened with increased inlet-outlet angles and flow channel widths.
Fluid flow rate significantly lowered maximum battery temperature, achieving optimal efficiency.
At 45° leaf vein angle, a maximum temperature of 306.58 K and a temperature difference of 6.38 K were noted.
