<p>Interlaced tubing elements form a conic spiral shaped heat exchange element/ The tubing elements are tilted while being helically wound, forming a substantially overall conic spiral structure having a central longitudinal axis. Tubing elements are tilted with respect to the central longitudinal axis, and may be continuously tilted or variably tilted. A heat exchange element is formed by a continuous tubing element that spirals around a central longitudinal axis, or by several interlaced tubing elements that are spaced adjacent to each other in a conic spiral shape. The tubing elements may have a plurality of fins on at least one of the outer surfaces or first and/or second side wall.</p> |
