The invention provides an efficient geothermal heat utilization
system and method based on
solid heat conduction. The
system comprises a
heat transfer well, an underground heat collection section, a ground heat exchange device and a
solid heat transfer rod, wherein the
heat transfer well is arranged in a stratum layer, the upper end of the heat transfer well extends upwards to the ground, the lower end of the heat transfer well extends downwards into a geothermal storage layer, the underground heat collection section is formed in the portion, located in the geothermal storage layer, of the heat transfer well so as to collect
geothermal energy in the geothermal storage layer; and the ground heat exchange device is arranged on the ground, the
solid heat transfer rod is arranged in the heat transfer well, one end of the solid heat transfer rod is connected with the ground heat exchange device, the other end of the solid heat transfer rod extends downwards to the underground heat collection section, and
heat energy in the
geothermal energy storage layer collected by the underground heat collection section is conducted into the ground heat exchange device. According to the efficient geothermal heat utilization
system based on solid heat conduction and a utilization method thereof,
solid medium is used for realizing geothermal transmission, and the core components including a solid heat transfer rod system and a related heat collection and
insulation system have the advantages of being efficient, environment-friendly, wide in application range and the like.
