Covering type energy pile buried pipe heat exchanger structure
The invention discloses a covering type energy pile buried pipe heat exchanger structure which comprises a concrete pile body and a pipeline system, and the pipeline system comprises a water inlet pipe arranged in the concrete pile body and a plurality of outer circular pipes fixed to the periphery of the concrete pile body in an embedded mode. A plurality of inner connecting pipes are communicated between the bottom of the water inlet pipe and the outer circular pipe at the lowermost end of the concrete pile body, a spiral heat exchange pipe is communicated between every two adjacent outer circular pipes, the spiral heat exchange pipes are embedded in the periphery of the concrete pile body, and the spiral directions of all the spiral heat exchange pipes are the same; the outer circular pipe arranged at the uppermost end is also communicated with a water outlet pipe; according to the structure, the heat exchange performance and heat exchange efficiency of the energy pile can be improved, and the pile body stress, the pile side friction force, the pile top settlement and the ultimate bearing capacity of the pile are improved by reducing the temperature change of the surface of the concrete pile body; and the spiral heat exchange pipe is arranged outside the concrete pile body, so that the flowing distance of cold (hot) water in the pipe is increased, and the heat exchange performance and the heat exchange efficiency of the energy pile are improved.
本发明公开了一种笼罩式能量桩埋管换热器结构，包括混凝土桩体和管路系统，管路系统包括布设在混凝土桩体内的进水管和若干嵌套固定在混凝土桩体外围的外圆管；进水管的底部与混凝土桩体最下端的外圆管之间连通若干内接管，相邻两个外圆管之间连通螺旋换热管，螺旋换热管嵌套在混凝土桩体外围并且所有螺旋换热管的旋向均相同；设在最上端的外圆管上还连通有出水管；本结构能够提高能量桩的换热性能，换热效率，通过降低混凝土桩体表面的温度变化，改善桩身应力、桩侧摩擦力、桩顶沉降以及桩的极限承载力；并且在混凝土桩体外设置螺旋换热管，提高冷(热)水在管内的流动距离，提高能量桩的换热性能和换热效率。
