First Claim
Patent Images
1. A tubular heat exchanger comprising:
- a plurality of bare and finned tubes disposed with their longitudinal axes substantially parallel, said tubes combined to form a tube bundle;
said bare tubes having no fins, and said finned tubes having longitudinally aligned fins extending from their external surfaces for dissipating the heat of hot fluid transmitted through said tubes;
each of said finned tubes positioned between or adjacent to a bare tube, arranged such that said finned tubes provide longitudinal support for said bare tubes, thereby eliminating the need for supporting means within the tube bundle.

Abstract
Disclosed is a heat exchanger tube bundle design that eliminates the need for tube supports or baffles within a heat exchanger tube bundle. The inventive configuration uses a combination of bare tubes and longitudinally finned tubes positioned such that the longitudinal fins act as spacing and supporting means within the tube bundle. The longitudinal fins provide spacing and support substantially along the entire length of the tubes within the bundle and eliminate the need for internal spacing or supporting means. Taking advantage of this inventive design, one can economically construct a tube bundle requiring only external rings to secure the tube bundle.
