摘　　要：本文建立了新型平板热管相变蓄热装置的模型,利用数值模拟软件Fluent 6.2.16对以石蜡作为相变材料的融化过程进行了详实的研究,得到了相变材料的温度场和液相体积分数随时间的变化情况,分析了相变界面的变化规律。同时对不同翅片尺寸、不同传热温差下的传热情况进行了对比,得到了其对传热过程的影响规律。In this paper,the software of Fluent 6.2.16 was used to establish the model of phase change thermal storage equipment with novel flat heat pipe,and the melt process was simulated taking paraffin wax as the phase change material.Based on the simulation,the variation trends of temperature field,liquid volume fraction and interface of phase change were discussed.Furthermore,the heat transfer process was compared under different size of fins and different temperature differences,hence the influence rules of these parameters on heat transfer process were achieved.
