Abstract
The performance of Li-ion batteries is highly dependent on the conditions and temperature distribution inside the battery units. Most of the batteries suffer from high heat dissipation and temperature which influence the battery unit life and efficiency. Therefore, a thermal cooling system is important to regulate the battery unit temperature and reduce the high heat dissipation effect. This study aims to examine the thermal cooling efficiency of a single Li-ion battery unit with a modified heat sink. The study was performed in a laminar flow regime with Reynolds numbers ranging from 20 to 120. The operating fluid is air and the heat sink is aluminum. The Li-ion battery units' heat sink was adjusted with elliptic holes as perforation located inside the walls of each fin. The elliptic holes are spaced evenly along with the fins with constant size and gap between them. The thermal performance in the battery unit is calculated using the MSMD function which is solved using the Ansys 18.1 software. The results indicate that the maximum battery unit temperature measured in the case is 343.1 K without a cooling system. The battery unit temperature decreased by 13% when only air cooling was applied. The use of a heat sink with elliptic perforation plays an important role in lowering the battery unit temperature. The temperature decreased by 21% compared to the case of without cooling.
