| 摘 要： | 总结了以往地热换热器孔外的理论传热模型，并将其归为两大类：有限长热源模型和无限长热源模型。在简要对其进行介绍和总结之后，进一步比较了他们之间的差别和联系。指出无限长模型不能适用于地热换热器长时间的传热分析，只能用来分析短时间内非稳态的传热分析。而有限长的传热模型由于考虑了地面作为传热边界对地下传热过程的影响，能够用来分析长时间的传热分析。

| Abstract: | This paper summarizes the heat transfer models for the outside of ground heat exchanger and these models are classified as two kinds, the infinite model and finite model. After briefly introducing the two kinds of model, the difference and relation are pointed. This paper indicates that the infinite model can not simulate the long period heat transfer process outside the borehole correctly. It can only be used for the unstead thermal analysis of short period, Because of considering the influence of ground surface, the finite model can be used for analyzing the long period heat transfer process. |
