Research on Liquid Cooling Pipeline Flow Mechanism based on Optimization of Battery Module Heat Dissipation Efficiency

Abstract

Optimizing heat dissipation efficiency is a core challenge in the thermal management systems of new energy batteries and a key issue for ensuring the safety and stable performance of these batteries. With the increasing adoption of high-power fast-charging technology, current cooling solutions struggle to effectively handle the transient high thermal loads of battery packs, leading to intensified risks of local overheating and thermal runaway. Therefore, this study achieves efficient heat dissipation by integrating a design layout with threaded pipe structures. This paper introduces a power battery compartment cooling device based on composite synergistic cooling technology. The device realizes precise temperature control of the battery compartment through the combined effect of phase change material buffering, enhanced heat transfer via threaded liquid cooling pipes, and dynamic adjustment with variable-frequency energy-saving fans. This study not only improves battery cooling efficiency but also extends battery lifespan, reduces the risk of thermal runaway, and provides theoretical support for optimizing thermal management systems in new energy batteries.
