| 目的 考虑到寒冷地区的低温气候以及多数温敏产品在2～8 ℃的保温要求，研究环保型蜂窝纸箱的保温性能及影响因素，以提供合理的防冻包装方案。方法 首先，对防冻保温箱进行有限元建模，实验测试蜂窝纸板等不同材料的表面辐射率和导热系数，分析蜂窝纸板厚度、孔径等因素对其导热系数的影响规律。最后，通过仿真和试验对比的方法，分析厚度以及内附材料对蜂窝纸箱保温性能的影响。结果 蜂窝纸板表面辐射率为0.81，导热系数随蜂窝纸板厚度和孔径的增加而略有降低，通过仿真和试验的对比，蜂窝纸板内附气泡膜相较于没有内附材料的防冻时长提升了9%，而内附反射箔的防冻时长仅提升了1%。结论 蜂窝纸箱在冷链物流领域可以替代传统泡沫材料，为冷链物流的可持续发展提供替代包装方案。 |

| Considering the low-temperature climate in cold regions and the insulation requirements of most temperature-sensitive products at 2-8 ℃, the work aims to study the insulation performance and influencing factors of environmentally friendly honeycomb cartons to provide a reasonable anti-freeze packaging solution. Firstly, the finite element modeling of the antifreeze insulation box, the experimental testing of the surface emissivity and thermal conductivity of different materials such as honeycomb cardboard, and the analysis of the influence law of the thickness of honeycomb cardboard, pore size and other factors on its thermal conductivity were conducted. Finally, the effect of thickness and the inner attached materials on the thermal insulation performance of honeycomb cartons was analyzed by simulation and experimental comparison. The surface emissivity of honeycomb cardboard was 0.81, and the thermal conductivity decreased slightly with the increase of thickness and aperture of honeycomb cardboard. Through the comparison of simulation and experiment, that of the honeycomb cardboard with bubble films inside was improved by 9% compared with those without inside material, while that of the honeycomb cardboard with reflective foils inside was improved by only 1%. Honeycomb cartons can replace traditional foam materials in cold chain logistics, providing an alternative packaging solution for the sustainable development of cold chain logistics. |
