摘　　要：对20英尺冷藏集装箱在不同堆码状态下的换热特性进行了模拟与分析。研究结果表明:冷藏集装箱的稳态壁面热流量随着送风速度的增加而升高,稳态回风温度随着送风速度的增加而降低。采用流固耦合算法对冷藏集装箱在货物装载时的工作过程进行了研究,可以看出冷藏集装箱内部货物温度的变化呈现递减的指数函数形式。增大送风速度或者分散装载,有利于提高货物的冷藏品质。The heat transfer characteristic of 20 feet size refrigerated container for different kinds of stacking are studied.The simulation results show that the heat transfer rate of wall increases with the promotion of wind speed,and the temperature of return air decreases with the promotion of wind speed.The numerical simulation for loaded state is performed by using fluid-solid interaction algorithm.The temperature variation of cargo is in good agreement with decreasing exponential function form.So it is feasible that increasing the wind speed or using the multipiece stacking can improve the quality of cargo.
