摘要：

随着风电、光电等清洁能源行业的快速发展，集装箱储能电站的建设需求巨大。传统的集装箱储能电站热管理系统通常由空调器提供冷量，全年运行能耗较高。本工作提出了一种利用蒸发冷却和天空辐射辅助供冷的热管自然冷却模块，介绍了模块结构和工作原理。基于典型城市的全年气象参数对模块的适用时长、全年供冷量及能效比进行了计算，分析了模块的节能效益。结果表明，蒸发冷却和天空辐射辅助供冷可有效延长热管自然冷却模块的适用时长，如果该模块分别应用于北京、西安、上海，则采用蒸发冷却+天空辐射辅助供冷后模块的适用时长分别增加22.95%、28.56%、13.06%。给出了热管自然冷却模块在我国主要城市的适用时长，可用于分析热管自然冷却技术在各地区的适用性。蒸发冷却和天空辐射辅助供冷均可提升模块的供冷能力，且前者的改善效果更加明显。蒸发冷却+天空辐射辅助供冷的热管自然冷却模块应用于北京、西安、上海时性能系数(COP)均值分别为24.2、22.3、19.7，远高于1级能效单元式空调机的全年能效比AEER。

Abstract:

With rapid development in wind power, photovoltaic, and other clean energy industries, demand for container energy-storage power stations is growing. Conventional thermal management systems for container energy storage power stations typically rely on air conditioning units for cooling, resulting in significant annual energy consumption. We propose a heat-pipe natural cooling module assisted by evaporative and sky-radiation cooling. Furthermore, we describe the module structure and working principle. We calculate the applicable time, annual cooling capacity, and energy efficiency ratio of the module based on the annual meteorological parameters of typical cities and analyze the energy-saving benefits of the module. The results indicate that evaporative and sky-radiation cooling can effectively extend the applicable time of the heat-pipe natural cooling module. If the module is applied to Beijing, Xi'an, and Shanghai, the applicable time of the module can be increased by 22.95%, 28.56%, and 13.06%, respectively, on applying evaporative and sky-radiation cooling. The applicable times of the heat-pipe natural cooling module in typical cities were given and can be used to analyze the applicability the cooling technology in different regions of China. Both evaporative and sky-radiation cooling can enhance the cooling capacity of the module, and the improvement by the former is more obvious. When the heat-pipe natural cooling module assisted by evaporative and sky-radiation cooling was applied in Beijing, Xi'an, and Shanghai, the average coefficient of performance was 24.2, 22.3, and 19.7 respectively, which are much higher than the annual energy efficiency ratio of a unit air conditioner with first-level energy efficiency.
