| Abstract: | Based on the research on the thermal storage of the underground concrete heat storage pile, and with the help of the single U-shaped heat exchanger, we establish the physical and mathematical models to make analysis of the temperature field around the underground concrete heat storage pipes heat exchanger. Then, through the simulation, we study the variation of heat storage pile body temperature with the pipe radi- us, buried pipe flow and other parameters, and sums up the trends of the concrete temperature field around the heat storage pile, which provide a reference for the future experimental research. |

| Keywords: | the ground floor of the vertical U-pipe underground concrete heat storage pile simulation analysis |
