Packaged Helical Heat Exchanger

Abstract

This invention provides an economical helical polymeric heat exchanger that packages tightly for handling and then is quickly assembled to its full length prior to placement in either the ground or water.

1 . A helical liquid-to-ground or liquid-to-water heat exchanger of continuous tubing with at least two flexible straps that securely hold the tubing, establish a maximum helical pitch, and allow compact packaging before installation, with at least two linear compression members that secure to the strips just prior to installation, where the compression members cause the heat exchanger to be installed in its extended position. 
     
     
         2 .  Claim 1  where the compression members secure to clips along the straps. 
     
     
         3 .  Claim 1  where the compression members insert through openings in clips along the straps. 
     
     
         4 .  Claim 2  where the compression members are retained with fasteners to the clips at both ends of the helix.
