Abstract: On the basis of model of buried heat exchanger with internal heat ｓｏｕｒｃｅ, ICEM is used to model the grid, and then the model is simulated by ANSYS. Based on the simulation results of ambient temperature field of single U type heat exchanger, the influences of heat transfer performance of heat exchanger and soil recovery characteristics of single heat exchanger U type which were vertical buried under different heat ex-change and soil.
