The invention relates to a geothermal heat conduction system comprising a double-walled thermotube system from metal or other material, which is resistant to heat and corrosion. Heat-conducting blades are inserted between the inner diameter of the outer thermotube and the outer diameter of the inner thermotube and connect the two tubes to each other. A tubular system for filling the tubes with water and evacuating the same is embedded in the interspace. At the bottom, a regulating flap is mounted. An actuating arm is fastened to control the regulating flap. The ends of the thermotube segments have connecting grooves and fastening clamps. They are clad with insulating material to minimize heat loss. The inner tube of the double-walled thermotube contains a guide for the heat transfer tube. After the first thermotube segment having a regulating flap the other segments are introduced one after the other into the borehole down to the desired depth and are interconnected. The heat transfer tube which is produced of a metal that is resistant to heat, pressure and corrosion is then introduced together with the heat-conducting fluid "heatboron". |
