The utility model discloses a buried pipe heat exchange system, including a buried pipe heat exchanger and a heat insulation board. The buried pipe heat exchanger includes an inlet branch pipe and an outlet pipe. The heat insulation board is located between the imported branch pipe and the outlet pipe; the heat insulation board is provided with several pipe cards from upper to lower, and the pipe card is used. The two ends of the pipe clip are respectively clamped by the import branch pipe and the outlet branch pipe. There is a heat insulation board between the inlet pipe and the outlet pipe to increase the heat resistance, avoid the heat short circuit and achieve high efficiency insulation. The pipe card is fixed on the insulation board, and the two integration can avoid the problem of loosening and shifting of the pipe card caused by the pipe resistance at the time of the pipe card, so as to better clamp the heat exchanger of the buried pipe.

技术介绍
地理管换热器是实现载热流体与土壤进行热量交换的关键传热器件,其中以单U型、双U型地埋管换热器应用最为广泛,然而受到钻孔孔径(约为110~150mm)的制约,使得地埋管换热器进出口支管间距非常有限,导致两管由于相互接触进行直接热量交换,或者通过埋管间回填料导热间接进行热量交换,产生″热短路″现象;对于双U型地埋管换热器来说,两进口管或出口管距离靠近也会影响载热流体与土壤换热。上述现象会导致地埋管换热能力小于设计值,据相关研究表明,热短路现象会使土壤源热泵运行效率低10%-20%。为了削弱热短路的影响,工程上采取的主流措施为用弹簧或管卡将两支管分开,但此方法不能解决两支管间由于回填料导热造成的热量损失;另外,施工过程中下管阻力往往直接作用于管卡上导致其松动移位,预期功能丧失。专利CN1982810A提出在回水管有热短路的管段外加套管,埋管与套管间抽真空,但这也妨碍了回水管与回填料间的有益换热;专利CN203629136U针对双U型地埋管换热器提出用钢条捆绑定位方式使两进口支管相互远 ...
