Abstract
The heat transfer model of coupled thermal conduction and groundwater seepage of multi-pipe heat exchanger was built. The influence of groundwater seepage on the different location borehole within the multi-pipe exchanger, groundwater seepage direction angle and arrangement of borehole on the multi-pipe exchanger were analyzed. The simulation results show that groundwater seepage weakened the mutual thermal effects on perpendicular flow direction, but enhanced the mutual thermal effects along the flow direction. No matter how the arrangement of the multi-pipe heat exchanger is, there is an optimal flow direction angle. The best thermal effect would be shown, if the multi-pipe exchanger layout along the optimal flow direction angle.
