Abstract

A method of forming a heat exchanger tube by folding a strip of heat conductive material into a "B" shaped double nosed tube. The strip is progressively plastically deformed to form a pair of corrugations, wherein each of the corrugations includes a series of alternating crests and web segments. An internal nose is defined by an outward extension of the outer most crest followed by an inward curve. The corrugations are then folded inward toward a surface of the strip forming a pair of folded corrugations defining a central wall along the first fold. The folded corrugations are then folded inward toward the same surface of the strip such that the central walls are tightly abutted against each other, and the internal noses are abutted up against a respective portion of the surface along the second fold, thereby forming the double nosed folded tube.
