摘　　要：为研究和改善载货后船舶集装箱内温度分布的不均匀性,以20 ft冷藏集装箱为研究对象,对现有T型槽道送风方式进行改进和优化,提出了一种新型局部送风方式;利用ICEM-CFD软件建立模型并进行仿真计算,揭示冷藏集装箱内温度分布特性,与原始模型进行对比分析,结果表明:在箱门附近引入局部送风系统可有效改善箱内温度分布,有效控制箱内温差1~2K,减小局部高温区域面积。局部送风系统还可以延迟装载货物时箱内温度上升速率,有效降低箱内能量损失。文章对进一步开展船舶冷藏集装箱内温度控制和节能优化具有借鉴意义。To study the temperature distribution inside marine reefer containers after loading and improve the uniformity of the inside temperature, a 20’ reefer container is selected as the research object, and the T-groove air supply mode is im-proved and optimized. A new type of local air supply is proposed. The model was established by ICEM-CFD software, and the simulation of temperature distribution inside the reefer container was taken. Compared with the original model, the re-sults show that, the local air supply system in the vicinity of the door can effectively improve the temperature distribution in the box,and the temperature difference inside the box is only 1 ？2K. High temperature area inside the box also narrowed. Local air supply system can also delay the temperature rise rate while loading goods, and the energy loss in the box was ef-fectively reduced. The work is a good reference for further development of temperature distribution and energy saving in reefer containers.
