| 设计了一种具有蓄冷功能的冷藏车箱体模型。为了评估此箱体的保温功能，首先对其传热效果进行了三维数值模拟, 然后以上海青为例对其进行了实验验证。结果表明，此冷藏箱体可以有效地减缓冷藏运输过程中上海青的温度回升速率，说明在冷藏车的箱体中添加复合相变材料可以有效提高其保冷效果。 |

| Abstract: |
| A new type of refrigerator cabinet with composite phase change materials was designed in this paper. In order to assess the refrigerator heat preservation function. First of all, the three dimensional unsteady phase change heat transfer process with variable heat source was simulated and calculated by ANSYS software. Then the simulation results were verified experimentally with cold storage and transportation of Shanghaiqing（Brassicachinensis L.）, the Chinese vegetable. The results showed that the temperature rise of Shanghaiqing inside the cabinet was delayed when the composite phase change materials was applied. So that adding composite phase change materials can effectively improve the effect of the cold in refrigerated vehicle. |
