摘　　要：应用有限元法,对冷板侧置及在不同冷板冻结温度和储藏食品温度下的车厢内温度场进行了三维模拟计算研究,得出了车厢内温度场分布和变化的规律及影响因素。结果表明:无论运输冻货还是果蔬都是车门附近的截面上紧靠车门的1点附近温升过高,其余各点温升均能保证运输货物的温度要求,应在车门附近的顶部增加两块顶置式冷板。Using the finite element method, the temperature field of car under the different freezing and food storing temperature, different the location of cold plate is calculated by means of three-dimensional sim- ulation. The contributory factor and rule of distributing and variation for inner temperature field was obtained. Results show that the temperature of in representative section close to the door of CPRC was increasing while transporting frozen goods or fruit, the temperature of any other part still guarantees the requirement for the food by adding two cold plates into the top of place close to car door.
