BOREHOLE THERMAL SOURCE Russian patent published in 2008 - IPC F24D3/08 F24J3/08 

FIELD: mining.

SUBSTANCE: invention relates to power engineering, in particular, to devices intended for generating heat produced other than by fuel combustion. The borehole thermal heat source contains a thermal water-supplying well linked to a water source, a drain zone and a thermal water consumer. The thermal water-supplying well is drilled so that its bottom crosses the driftway and serves as a water conduit. A surface reservoir, with a thermal water-supplying well being drilled thereon, an underground water-bearing zone/zones or a surface reservoir with underground zone/zones can be used as a water source. The intersection of the thermal water-supplying well with the driftway located below serves as a drain zone. Additionally, the source contains a swirling thermal water-supplying heat-generator connected with the well and installed under the dynamic level thereof. Water pressure is sufficient to produce the thermal energy; water consumer is wired up, by means of the thermal water pipeline, to the outlet of the swirling heat-generator in the drain zone of the thermal water-supplying well. The swirling heat-generator is disposed in the driftway, connected to the well in the area of its intersection with the driftway and has a pumping plant with binding. Thermal water pipeline is made as an additional well drilled from the driftway prior to its intersection with the daylight surface, in the zone of the thermal water consumer threreto the pipeline of the thermal water consumer is attached. Mouth of the additional well is connected to the pumping plant binding.

EFFECT: simplified thermal source and thermal consumer traffic channel; higher hydro-energy potential in high-water period; operational security and invulnerability.
