与储能集装箱相比，储能户外柜集成度高、灵活性高、初始投资低，在分布式发电系统、微电网及电力辅助服务市场等领域发挥着重要作用。为解决顶部电池模组（PACK）在运行过程中的高温问题，本文从户外柜的换热特性展开研究，分析了不同制冷剂流量、散热方式、太阳辐射对顶部PACK温度分布的影响。研究结果表明：在加装风扇的方案下，温差（2.22℃）较液冷板方案仅高0.11℃，但综合成本降低了10%；太阳辐射与制冷剂流量对电池温度影响显著，其中太阳辐射可使电池最高温度升高约1.03℃。综合考虑冷却效果、成本及安装维护便利性等因素，确定加装风扇为优化方案。研究结果可为储能户外柜提供科学、实用的热管理解决方案，有助于推动储能技术的高效发展。
Abstract：Compared with energy storage containers, outdoor energy storage cabinets exhibit higher integration, flexibility, and lower initial investment costs, playing a critical role in distributed power systems, microgrids, and power auxiliary service markets. To addresshigh-temperature challenges in top-mounted battery packs(PACK) during operation, this study investigates heat exchange characteristics of outdoor cabinets, analyzing the impact of different refrigerant flow rate, cooling methods, and solar radiation on top PACK temperature distribution. Results indicate that while the temperature difference(2.22 ℃) under fan-equipped configurations is only 0.11 ℃ higher than the liquid cooling plate solution, comprehensive costs are reduced by 10%. Solar radiation and refrigerant flow rate significantly influence battery temperature, with solar radiation potentially increasing maximum temperatures by approximately 1.03 ℃. By comprehensively considering factors such as cooling efficiency, cost, and installation/maintenance convenience, the optimized fan installation solution was determined. The research results provide a scientific and practical thermal management solution for outdoor energy storage cabinets, promoting the efficient development of energy storage technology.
