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.
