AB - Buried pipe leakage can lead to poor heat transfer performance and even system failure. Leakage analysis of buried tube greatly affects the operation condition diagnosis for the heat exchange in buried tube. In this study, the simulation software was applied in analyzing heat transfer process and efficiency of the buried pipes under different leakage conditions. Moreover, changes in outlet temperature, water pressure and flow rate were simulated at different positions and diverse sizes of the leakage port. According to our results, the size of leakage port greatly affected the parameter variation of the outlet port when the system started and stopped, thus affecting the cooling effect. In addition, position of the leakage port also had obvious influence on the physical state of the outlet water.
