In this study, a liquid immersion cooling system based on the pool boiling mechanism was proposed, and its cooling performance for 4680 battery packs under high-C rate conditions was evaluated. The effects of bubble growth and heat transfer mechanism were analyzed. Based on the obtained findings, the subsequent conclusions were derived:
