摘　　要：分析了顺排和叉排方式排列的盘管式蓄冰槽的传热过程,提出了相应的简化假设,并在此基础上建立了九管管束模型。通过对不同管径下不同排列方式的蓄冰槽内的传热特性的ANSYS模拟研究,得出管径对传热的蓄冰槽影响相对较小,盘管管顺排既可以简化布置方式,且顺排的传热特性更优于叉排,同时又满足温度场均匀的要求,因此采用顺排的布置方式比叉排更有利。This paper analyzed the heat transfer process in the inside melting of ice storage tank which in along-arranged and cross-arranged.We proposed the corresponding simplified assumptions,and on this basis,established a nine bundle model.ANSYS simulation study was also studied on ice storage tank which in the different arrangement with the different pipe diameters.It obtained that diameter effect on heat transfer of ice-storage tank is relatively small,tubes in-line arrangement,which not only simplified layouts and enhanced the heat transfer characteristics,but also met the requirements of uniform temperature pattern,was better than staggered style to the performance of ice storage tank.
