This report investigates the thermal performance of three liquid cooling designs for a six-cell battery pack using computational fluid dynamics (CFD). The first two designs, vertical flow design (VFD) and horizontal flow design (HFD), are influenced by existing. . This numerical study examines the impact of flow configuration for an improved minichannel cold plate with a fragmented design. With simple modifications to the existing design, the improved design offers better heat augmentation capability along with reduced pressure drop. The size of the lithium-ion battery is 148 mm × 26 mm × 97 mm, the positive pole size is 20 mm × 20 mm × 3 mm, and the negative pole size is.
