This study seeks to address the need for effective heat management of high-capacity batteries, particularly in electric vehicles, by manufacturing a new type of Radial Type Vapor Chamber Heat Sink. The heat sink design involves adding a condensation part vertically to the edge of the flat Vapor Chamber, using stainless steel with a U-shaped cross-section and an internal capacity of 140 ml. The study also aims to investigate the internal flow phenomena of the heat sink and evaluate its performance. To improve heat emission performance, copper fins and hollow fins were attached to the heat sink, and various sensitive factors were manipulated in experiments to determine the optimal performance of the new Radial Type Vapor Chamber Heat Sink. The results of the study are expected to provide insights into the design of effective thermal management systems for high-capacity batteries, particularly in electric vehicles, and contribute to the development of more efficient and sustainable energy solutions. Overall, this study has significant implications for the advancement of battery technology and its applications in various industries.
