摘 要： 建立了有地下水渗流时地源热泵地埋管管群热渗耦合传热模型，通过数值模拟方法研究了地下水渗流对管群内不同位置钻孔换热的影响，渗流方向角和钻孔布置形式对管群换热的影响等方面的内容。研究结果表明，地下水的渗流削弱了管群在垂直于渗流方向上的热影响，增强了沿渗流方向的热影响。地埋管管群无论顺排还是叉排布置，都存在一个最优渗流方向角，此时管群换热效果最好，而且渗流方向角的影响随渗流速度的增大而增强。如果沿最优渗流方向角布置管群，选择顺排还是叉排布置形式对整个管群的换热影响并不大。 关键词： 地源热泵、地下水渗流、管群、渗流方向角、布置形式 Heat Transfer Analysis Of Groundwater Seepage For The Multi-Pipe Heat Exchanger Of Ground Source Heat Pump Abstract: The heat transfer model of coupled thermal conduction and groundwater seepage of multi-pipe heat exchanger was built. The influence of groundwater seepage to the different location borehole within the multi-pipe exchanger, groundwater seepage direction angle and arrangement of borehole to the multi-pipe exchanger were studied in this paper. The simulation results show that groundwater seepage weakened the mutual thermal effects on perpendicular flow direction, but increased the mutual thermal effects along the flow direction. No matter how the arrangement of the multi-pipe heat exchanger, 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. The little difference would be shown between the aligned arrangement and crossing arrangement form of boreholes, if the multi-pipe exchanger layout along the optimal flow direction angle.
