Abstract
A multi-circuit arrangement for a wound coil heat exchanger and a method for making it are disclosed. The coil circuits are wound from a continuous length of spine fin tubing; locations are determined for breaking into the wound, continuous length of tubing to form adjacent circuits; the tubing is cut; the cut ends are pulled toward the manifold and downwardly so that adjacent ends angle toward each other; and transition tubes are secured to the cut ends, the tubes crossing each other to form an 'X' configuration.
