目的 为了提高保温箱的保温性能，对冷冻海鲜产品保温箱的结构进行设计和优化。方法 针对冷冻海鲜产品“小批量，多批次”的运输需求，设计一款用于冷冻海鲜产品运输的保温箱，同时利用Ansys Workbench进行瞬态热分析，得出保温箱内的温度场变化情况，并通过分析温度场模拟的结果来改进保温箱的结构。最后通过实验与数值模拟相比较的方式，验证模拟的可靠性。结果 在保温箱边角处增加少量保温材料就能将保温箱的保温性能提高9.9%。结论 通过数值模拟的方式来改进保温箱的结构是可靠的。

To improve the thermal insulation performance of the incubator, design and optimize the incubator structure of frozen seafood products. With respect to the transportation demand of "small batch volume and multi-batches" of frozen seafood products, an incubator for the transportation of frozen seafood products was designed. At the same time, the transient thermal analysis was conducted with Ansys Workbench to get the temperature field change in the incubator; and the incubator structure was improved by analyzing the results of the temperature field simulation. Finally, the simulation reliability was verified by means of comparison on the experimental and numerical simulations. Adding a small amount of thermal insulation materials at the corners of the incubator could enhance 9.9% of the thermal insulation performance of the incubator. The incubator structure improved by means of numerical simulation is reliable.
