中文摘要:
      目的 研究保温材料厚度、保温材料导热系数、对流系数、温差对一种典型潜热性控温包装保温效果的影响。 方法 对该种典型控温包装系统进行计算机建模,将建好的模型导入 Ansys 中,通过分别改变模型中的保温材料厚度、保温材料导热系数、对流系数、温差等参数,以模拟物最先达到临界温度所经历的时间作为保温有效时间,并研究其影响。 结果 厚度对保温时间影响明显, 成正比例关系,在较低的对流系数,较低的温差以及较小的导热系数下它们的变化对保温时间影响明显。 结论 此种典型控温包装系统在蓄冷剂量一定时,保温容器厚度对其影响明显,温差、对流系数、导热系数在很小的范围内对其影响明显。
英文摘要:
      Objective To study the effects of the thickness and thermal conductivity of insulation material, the convection coefficient and the temperature on the holding time of a typical latent-heat insulation package. Methods A model was built for the typical latent-heat insulation package system by computer, and was then imported into Ansys. The thickness and thermal conductivity of the insulation material, the convection coefficient and the temperature were changed in the model, and the time required by the mimic to first reach the critical temperature was set as the holding effective time. The effects were studied. Results The holding time was obviously influenced by the thickness, and there was a positive correlation. At lower values, the changes of the convection coefficient, the thermal conductivity and the temperature had obvious impacts on the holding time. Conclusion At a certain amount of coolant, the typical packaging system was significantly influenced by the thickness of the insulated container, and the convection coefficient, thermal conductivity and temperature exerted obvious effects in a small range.
