Abstract

Disclosed is a geothermal heat exchanger (1) has a pressurized water injection pipe (11), to which pressurized process water is supplied by a high-pressure water supply pump (17). The heat exchanger also has a water extraction pipe (12) which, with respect to the process water that descends to a geothermal region (10) through the pressurized water injection pipe (11), raises hot water produced by heat supplied from the geothermal region (10), in a state wherein the hot water does not include steam, with the hot water extracted from the hot water extraction pipe (12) being sent to a steam generator (21) and extracted as steam only within the steam generator (21). The pressurized water injection pipe (11) is arranged at the outer circumferential side of the hot water extraction pipe (12), and is constructed such that the hot water is transferred to the hot water extraction pipe (12) through inlet holes (15) provided in the lower portion of the pressurized water injection pipe (11).
