Pipe for geothermal heating and cooling systems

Abstract

A conduit for use in a geothermal heating and cooling system which includes an elongated tubular member having first and second ends, the member having an outer surface. A longitudinally extending divider wall is disposed within the tubular member. The divider wall divides the interior of the tubular member into first and second fluid flow passageways extending longitudinally within the tubular member. The apparatus further includes a cup shaped member disposed on the second end of the elongated tubular member. The cup shaped member directs all fluid flow in the first fluid flow passageway from the first end to the second end into the second end of the second fluid flow passageway. Other forms of the invention have first and second elongated tubular members that have first and second ends and each of the tubular members has an outer surface. Each of the elongated tubular members may have a transverse cross-section having (1) an arcuate wall having a radius R and (2) a generally planar wall joined to the arcuate wall. A cup shaped member is disposed on the second end of the elongated tubular member. The cup shaped member directs all fluid flow in the first fluid flow passageway from the second end thereof into the second end of the second fluid flow passageway.
