基于相变材料（PCM）的储能系统具有高储能密度的优势，但其固有的低热导率导致传热性能不佳，需进行强化。为此，引入热管作为热桥，利用其蒸发段从热源吸热和冷凝段向PCM放热实现热量的高效间接传递，以强化系统的换热。设计了一种新型的热管－翅片－折流板复合结构，采用焓－多孔介质模型进行三维数值模拟，系统研究了热管布置方案、翅片构型（环形/纵向/螺旋）和折流板间距对系统储热性能及经济性的影响。模拟结果表明：通过优化热管布局可有效提升系统的蓄热效率与经济效益；与纵向翅片管和环形翅片管相比螺旋翅片管熔化速率最快且η值最高；当折流板间距为140 mm时复合结构系统传热性能最佳，且能兼顾蓄热效率和经济性。

Phase Change Material (PCM)-based thermal energy storage systems offer the advantage of high energy storage density; however, their inherently low thermal conductivity results in poor heat transfer performance, necessitating enhancement strategies. To ad-dress this, heat pipes are integrated as thermal bridges, leveraging their evaporation section to absorb heat from the source and their condensation section to release heat to the PCM, thereby enabling highly efficient indirect heat transfer and augmenting the sys-tem's thermal exchange. This research designs a novel composite structure integrating heat pipes, fins, and baffles, employing a three-dimensional numerical model based on the enthalpy-porosity method to investigate the effects of heat pipe configuration, fin type (annular, longitudinal, spiral), and baffle spacing on the system's thermal storage performance and economic benefits. Simula-tion results demonstrate that an optimized heat pipe layout can effectively enhance both thermal storage efficiency and economic viability; among the fin types evaluated, the spiral finned tube achieves the fastest melting rate and the highest comprehensive evaluation index (η); furthermore, a baffle spacing of 140 mm optimizes the heat transfer performance of the composite system, achieving an effective balance between thermal storage efficiency and cost-effectiveness.
