摘　　要：针对相变材料在储能系统中传热效率偏低的问题,提出一种基于场协同理论的相变储能结构优化方法。在非稳态传热条件下,以石蜡为测试工质,分别对5种不同翅片角度及2种翅片形状在储能系统内的传热效率影响进行分析。不同翅片角度分析结果表明,在相同时间内、不同角度下石蜡熔化与凝固速率各不相同,翅片在45°~60°区间时,熔化与凝固速率相对较高。基于场协同数(Fc)的协同程度及数值模拟,分析发现翅片协同角度为56°时协同性最好,翅片对应的协同角为最佳场协同角,石蜡熔化与凝固速率最快。在此基础上对不同翅片形状进行研究分析,结合仿真对2种不同翅片形状进行优化。结果表明,在设定时间内,优化后的翅片储能单元内熔化速率提升4.5%,凝固速率提升8%,所提方法的有效性得到了验证。In other to improve the heat transfer efficiency of phase change energy storage systems,a structural optimization method was proposed based on field synergy.The relationship between five fin angles and two fin shapes inside the energy storage system were analyzed to reveal paraffin heat transfer efficiency,under the changing non-steady-state heat transfer.It was found that the melting and solidification rates of paraffin will vary with different fin angles in the same time.The melting and solidification rate of the fin is relatively high in the range of 45°-60°.Based on the synergy of field cooperation number(Fc)and numerical simulation,it is found that the finned coordination angle is 56°,the finned coordination angle is the best field coordination angle,and the paraffin melting and solidification rate is the fastest.On this basis,different fin shapes are studied and analyzed,and two different fin shapes are optimized by simulation.The results showed that the paraffin in the optimized energy storage system melting rate and solidification rate has been increased by 4.5%and 8%,compared to before optimization in the designated time.The effectiveness of the proposed method has been validated.
