Abstract Surface heat transfer coefficient is one of the crucial parameters for determining the system thermal resistance of insulating packaging. However, the surface heat transfer coefficient which couples with the temperature field in insulating packaging is difficult to experimentally measure and independently calculate. In this study an iterative method based on a semi-infinite phase change model was proposed to solve the coupling parameters of surface heat transfer coefficient and temperature field. Then, the semi-infinite phase change model curves were compared with classic Neumann model and Mehling model. Furthermore, the affecting parameters of surface heat transfer coefficient were discussed through this semi-infinite phase change model, and a concise prediction model of surface heat transfer coefficient was also developed for engineering application. Finally, this concise prediction model was verified by “Ice Melting Method”. The results indicate that the proposed semi-infinite phase change model and iterative method can simultaneously calculate the coupling parameters of surface heat transfer coefficient and the temperature field in insulating packaging, and show a consistent with the classic Neumann model and Mehling model. The key parameters of surface heat transfer coefficient include the thickness and thermal conductivity coefficient of insulating wall, and the excess temperature also significantly influences the surface heat transfer coefficient. Furthermore, the system thermal resistance calculated by the novel concise prediction model has a good agreement with the experimental data of “Ice Melting Method” presented by Burgess.

相变材料绝缘包装表面传热系数预测模型

摘要 表面传热系数是决定绝缘包装系统热阻的关键参数之一。然而，绝缘包装中与温度场耦合的表面传热系数很难通过实验测量和独立计算。本研究提出了一种基于半无限相变模型的迭代方法来求解表面传热系数和温度场的耦合参数。然后，将半无限相变模型曲线与经典的Neumann模型和Mehling模型进行了比较。此外，通过该半无限相变模型讨论了表面传热系数的影响参数，并为工程应用开发了简明的表面传热系数预测模型。最后，通过“融冰法”验证了这个简洁的预测模型。结果表明，所提出的半无限相变模型和迭代方法可以同时计算绝缘包装表面传热系数和温度场的耦合参数，与经典的Neumann模型和Mehling模型一致。表面传热系数的关键参数包括保温壁的厚度和导热系数，超温对表面传热系数也有显着影响。此外，
