Abstract

The heat transfer system includes a plurality of wound tube coils fixed within the holes of at least three plates disposed in a radiating axial manner from the axis of the system. The tube coils are wound helically or spirally and are fixed at three points about the holes through which they pass.

Claims

1. A method of making a heat transfer system having a plurality of wound tube coils fixed in a plurality of plates having fully encompassed apertures in the plane of the plates comprising the steps of mounting the radiating plates in a secured radiating manner with the plates disposed in spaced circumferential relation, bending a straight tube to impart a curvature therein, coiling the curved tube about itself to form a tube coil, and inserting the tube coil perpendicularly into the plates into and through the apertures of the apertured plates.

2. A method as set forth in claim 1 wherein the curved tube is coiled into a helical configuration and the helical tube coil is inserted into the apertured plates in a helical manner.

3. A method as set forth in claim 1 wherein said steps of coiling and inserting are performed simultaneously.
