COAXIAL GEOTHERMAL PROBE AND METHOD OF ITS UNDERGROUND INSTALLATION Russian patent published in 2017 - IPC F24J3/08 

FIELD: physics.

SUBSTANCE: invention relates to a coaxial geothermal probe and the method for underground installation, and a method for the geothermal probe operation as well. Coaxial geothermal probe includes a central core barrel (11), capable to expand the tubular casing, which limits the annular gap (15), going from the core barrel to the outside, and the core barrel (11) and the annular gap (15) are performed so, that ensure the flow of fluid heat conductor medium along them. The tubular casing is formed by a tubular shell (14), designed to expand under the action of high internal pressure, which covers the core barrel (11) in a packed folds state and after entrance into the well (1) under the geothermal probe, takes a stable final form under the action of the supplied over pressured fluid medium, and in the embedded state of the probe (10) is directly adjacent to the walls (2) of the well (1) under the geothermal probe.

EFFECT: invention is directed to the increase of the heat energy selection from the surrounding soil.
