U-shaped heat exchange structure for geothermal energy of middle-deep layer hot dry rock

The utility model discloses a medium-deep layer hot dry rock geothermal energy U-shaped heat exchange structure which comprises a first pipeline, a second pipeline is arranged on one side of the first pipeline, the first pipeline is communicated with the second pipeline through a third pipeline, a supporting mechanism is arranged at the upper end of the first pipeline and the upper end of the second pipeline, and two vertical plates are arranged at the bottom end of the supporting mechanism. The two vertical plates are located on one side of the first pipeline and one side of the second pipeline respectively, a plurality of clamping mechanisms are arranged between the first pipeline and the corresponding vertical plate and between the second pipeline and the corresponding vertical plate, the flowing time of pipeline fluid is prolonged through the third pipeline arranged in a snake shape, and therefore more heat can be conveyed at a time, the heat exchange efficiency is improved, and meanwhile the heat exchang
