摘要: A method of installing a tubular heat exchanger into soil includes providing the tubular heat exchanger and screwing the tubular heat exchanger into the soil with an installation apparatus. The installation apparatus may be removed from the soil without removing the tubular heat exchanger from the soil.

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.
