Enhanced Battery Thermal Management Using Multi-Channel Heat Sinks with Curved Cross-Sectional Profiles
Year: 2026
Type: conference-paper
Abstract: In the development of electric vehicles, ensuring safe and reliable thermal control of lithium-ion battery packs remains a critical challenge. Thermal stress during operation is further exacerbated by compact pack configurations, fast-charging requirements, and the continuous increase in energy density. The present work introduces a novel Battery Thermal Management System (BTMS) designed to mitigate the intensified thermal stress associated with these constraints. A multi-microchannel heat sink featuring a curved cross-section is proposed and numerically investigated. A comparative analysis is performed to assess the thermal management of battery packs and compare cooling performance of rectangular and curved cross-section. A parametric study has been conducted to optimize the thermal management system. Integrating curved microchannel heat sinks into the thermal management system leads to a significant reduction of maximum battery temperature and temperature non-uniformity.
