基于储能用280 Ah风冷电池包流道结构和导流板的协同优化
A study on the synergistic optimization of flow channel structures and guide plates in a 280 Ah air-cooled battery pack for energy storage
摘要
Abstract
The traditional air-cooled thermal management system for battery packs is known for its simple design and low cost.However,it struggles with poor cooling uniformity and local overheating,particularly in high-power-density applications.To address this,two air duct structures and a novel air-cooled guide plate were designed using principles of fluid dynamics and heat transfer.Through simulations in Fluent,combined with Bernardi's heat generation theory and the Realizable k-ε turbulence model,the thermal performance of double"Z"and"U"-shaped ducts was analyzed.The double"Z"duct was selected to further investigate the effects of guide plate configuration,hole size,and inlet air velocity on the temperature and flow fields.Resultsshow that guide plates optimize flow distribution and improve internal temperature uniformity.Smaller holes in the guide plate significantly lower the maximum temperature,while higher inlet air velocities enhance overall cooling and minimize temperature variation.This study demonstrates that the proposed micro-perforated air-cooled unit effectively dissipates heat during high-rate operations,improving the lifespan and safety of energy storage battery packs.关键词
