摘要： The present invention relates to a geothermal heat exchange system and a method of constructing a geothermal heat exchange system, and more specifically, to a geothermal heat exchange system which is to be installed in a borehole in the ground, the borehole being divided into a ground surface section and a shallow geothermal source section, the shallow geothermal source section of the borehole, which is hardly influenced by the atmospheric or ground surface temperatures, is filled with conventional heat conductive grouting material with high thermal conductivity, and the ground surface section of the borehole is filled with thermal insulation grouting material or thermal insulation cartridges to prevent the heat transferring medium in the geothermal heat exchange system, which has the geothermal heat obtained from the shallow geothermal source, from losing heat in the winter time or obtaining heat in the summer time when it passes through the ground surface section which is much influenced by the atmospheric or ground surface temperatures, thereby a geothermal heat exchange system that can increase the acquisition rate of geothermal energy, and a method of constructing the geothermal heat exchange system.

摘要： An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.

摘要： Apparatus includes a heat extraction system (SWEGS) in combination with some further apparatus for implementing some further functionality, e.g., associated with cooling/heating, remediation, mining, pasteurization and brewing applications. The SWEGS generates geothermal heat from within a drilled well, and includes a heat conductive material injected into an area within a heat nest near a bottom of a drilled well between a heat exchanging element and rock surrounding the heat nest to form a closed-loop solid state heat exchange to heat contents of a piping system flowing into and out of the heat exchanging element at an equilibrium temperature at which the rock surrounding the heat nest and generating the geothermal heat continually recoups the geothermal heat that the rock is conducting to the heat conductive material and above which the geothermal heat generated by the rock surrounding the heat nest dissipates as the heat conductive material conducts heat from the rock surrounding the heat nest to the heat exchanging element. The heat conductive material may be configured to solidify to substantially fill the area within the heat nest to transfer heat from the rock surrounding the heat nest and the heat exchanging element. The piping system may be configured to bring the contents from a surface of the well into the heat nest and carry heated contents to the surface of the well from the heat nest. The closed-loop solid state heat exchange may be configured to extract geothermal heat from the well without exposing the rock surrounding the heat nest to a liquid flow, and provide heated contents to the piping system for further processing. The further apparatus receives the heated content and further processes the heated content in order to implement some further functionality based at least partly on using the heated content.
