摘　　要：为研究布置真空绝热板对冷藏集装箱内温度分布的影响,以20ft机械式冷藏集装箱为研究对象,建立箱内空气对流与换热的物理和数学模型。采用标准k-ε紊流模型,对稳态下的真空绝热板冷藏集装箱和聚氨酯冷藏集装箱内温度场分布情况进行模拟仿真。模拟结果表明:采用真空绝热板作为保温材料,冷藏集装箱箱内温度场分布状况明显优于聚氨酯冷藏集装箱,而且平均温度能够降低0.8K。最后,对20ft实体聚氨酯冷藏集装箱进行实验,仿真与实验结果能够较好吻合,验证了模型的准确性。In order to study the effect of the vacuum insulation panel （VIP） on the uniformity of tempera- ture distribution inside reefer container, a physical and mathematical model of the air flow and heat transfer inside a 20-feet reefer container is established. The standard k-ε turbulent model is adopted to simulate the uniformity of temperature distribution inside reefer container equipped with VIP or polyure- thane under the steady state. The result shows that the uniformity of temperature distribution inside reefer container equipped with VIP is better than that with the polyurethane. Meanwhile, the average temperature is reduced by 0.8 K, and the simulation result has significance to improve the quality of refrigerated transport. At last, an experiment on a 20-feet polyurethane reefer container is conducted, and the experimental result is well agreeable with the simulation, thus verifying the accuracy of the mathematical mode.
