Simulating a Liquid Cooling Plate for EV Batteries

Effective cooling methods are crucial for proper thermal management of electric vehicle (EV) battery packs. Excessive or non-uniform temperatures can accelerate battery degradation, reduce efficiency, and pose serious safety risks. In this video, we modeled four different liquid cooling plate geometries (convex, u-shaped, airfoil, and honeycomb), comparing the thermal and hydraulic performance of each to determine the most efficient design. A glycol-water mixture is pumped through the cooling plate, which is mounted beneath a lithium-ion battery pack generating a constant heat flux. We conducted the simulations with CONVERGE’s Under-Relaxation Steady (URS) solver, which provides fast and reliable results for steady-state simulations. CONVERGE’s autonomous meshing and turbulence modeling helped resolve the flow inside the complex internal channels, and conjugate heat transfer modeling captured the heat exchange between the coolant and the solid plate. We analyzed the pressure drop, maximum temperature, and temperature distribution for each design. Our results show that the convex structure provides the best balance of effective cooling and low flow resistance. Convergent Science's CONVERGE is an innovative computational fluid dynamics (CFD) software that eliminates the grid generation bottleneck from the simulation process through autonomous meshing.
