Abstract
Coil assemblies for use in heat exchange applications are made using polymeric tubes, some with heat exchange and water redistribution media integral with the coil assembly and others with a water distribution subassembly integral with the coil assembly. One coil assembly includes at least two generally linear passes that are connected by return bends formed by folding an array of polymeric tubes. The passes have an array of at least two layers of polymeric tubes that pass through alignment holes in tube spacers only along the passes to maintain the tubes in substantially the same relative positional relationship to each other in the passes and in the return bends. Methods are explained for forming the coil assemblies and components, including the tube spacers and tube sheets to connect the coil assembly to inlet and outlet manifolds for the processing fluid flowing internally through the tubes.
