SYSTEM AND METHOD OF EXTRACTING HEAT FOR EXTREME MEDIA Russian patent published in 2025 - IPC F24T10/17 F24T50/00 

FIELD: geothermal power engineering.

SUBSTANCE: tool (100) for extracting heat from a deposit includes shoe (130) made from a material which can withstand temperatures above 500 °C, outer pipe (120) attached to shoe (130), inner pipe (110) located inside outer pipe (120) and forming annular space (112) with outer pipe (120). Inner pipe (110) has through hole (114) and flexible connection (140) configured to connect outer pipe (120) to shoe (130) so that outer pipe (120) can be extended and contracted without fluid leakage (154) inside annular space (112). Inner pipe (110) and outer pipe (120) are configured to form continuous circuit (156) for fluid medium (154) between the upper part of annular space (112) and the upper part of through hole (114) while providing the possibility of direct contact of fluid medium (154) with shoe (130). Heat removal system (900) for heat removal from the deposit includes said heat removal tool (100).

EFFECT: obtaining heat from high-temperature heat sources.
