PURPOSE: A geothermal heat exchanger and an installation method thereof are provided to insert the geothermal heat exchanger into a mounting pile without damages because a rolling member of a geothermal heat exchanger body firstly contacts with an inner surface of the mounting pile. CONSTITUTION: A geothermal heat exchanger(50) comprises a geothermal heat exchanger body(51) and more than one rolling member(55). The geothermal heat exchanger body is inserted into a dug bore hole. The rolling member is coupled to a leading end of the geothermal heat exchanger body. The geothermal heat exchanger body contacts with an inner surface of the dug bore hole and rolls through the rolling member while the geothermal heat exchanger body is inserted into the dug bore hole. |
