Computational Analysis of Heat Dissipation Strategies in Li-Ion Battery System Using Aluminium 7075 and Aluminium 6061

Abstract

This study examines the thermal behaviour of batteries by doing a computational fluid dynamics (CFD) analysis on them using ANSYS. The analysis focuses on various heat sink configurations, including situations without heat sinks as well as those with aluminium alloys 7075 and 6061 of varying thicknesses. The purpose of this study is to determine how effective various setups are in preventing thermal runaway and maintaining temperature rises that are acceptable within predetermined parameters. The findings demonstrate that thicker heat sinks are more effective in improving heat dissipation and the overall performance of battery cooling systems. The comparisons made between the various materials and thicknesses provide insights into the most effective design for heat management systems. In the end, this research contributes to enhanced battery safety, performance, and longevity. Additionally, it serves as a vital reference for engineers and researchers working to advance energy storage technology across a variety of applications.
