GEOTHERMAL DEVICE Russian patent published in 2014 - IPC F24J3/08 

FIELD: power industry.

SUBSTANCE: geothermal device includes a heat exchanger connected to a heat pump, a subsurface heat exchanger installed in a geothermal well, pipelines attaching the heat exchangers so that a closed system is formed, which is filled with a working medium in the form of liquid; with that, the subsurface heat exchanger includes downtake and rising pipes interconnected with each other in the lower zone. Free space of the geothermal well is filled with a filler with high draining ability; the subsurface heat exchanger contains at least six rising pipes located from the downtake pipe at the distance that is not shorter than their diameter; with that, the pipes of the subsurface heat exchanger are interconnected with each other by means of a head piece. The downtake pipe has the possibility of the uniform supply to its outer surface of draining liquid and the filler of the geothermal well with the possibility of its moistening. The geothermal well filler moistening system includes a storage chamber located below the head piece.

EFFECT: improving the thermal capacity of a subsurface heat exchanger and enlarging its scope of application.
