Geothermal heat exchanger for extracting geothermal energy from dry rocks by means of heat transfer medium

摘要

The method of extracting geothermal energy from dry hot rocks in a closed geothermal heat exchanger circuit by means of a circulating heat transfer medium comprises the transferring of heat extracted from the heat transfer rocks to the heat transfer medium in the closed circulation circuit with minimizing heat and hydraulic losses as well as minimizing its losses through the geothermal heat exchanger. The duct of a heat exchange production part (3) is formed ascending in the direction from point A to an outlet part (4) of the geothermal exchanger, where the pitch angle is 1 ° to 20 ° from the horizontal direction.
