渗流对地下换热器传热影响的研究

In this paper, using finite element software to build a U-pipe heat transferring model, to simulate the long-running case of the winter and summer heat transfer, and analysis groundwater seepage and groundwater infiltration flow rate on heat transfer. Reached the following conclusions: The existence of groundwater seepage can change the temperature field distribution clearly, and is conducive to the heat distribution. The greater of flow velocity, the faster of heat dissipation, so the heat around the pipe can loss timely, and can reduce the cumulative effect of heat effectively.
