Abstract
A heat exchanger tube includes a tube body forming a hollow passageway and having a U-shaped tube section defining a return bend, a pair of straight tube sections and a pair of transition sections. Respective ones of the straight tube sections are connected to the return section with respective ones of the transition sections disposed therebetween. The straight tube sections extend generally parallel to one another. Each straight tube section has a straight tube cross-sectional width and the return bend has a return bend cross-sectional width that is smaller than the straight tube cross-sectional width. Multiple heat exchanger tubes can be connected together to form a serpentine heat exchanger tube. Multiple serpentine heat exchanger tubes or multiple heat exchanger tubes can be assembled together to form a heat exchanger apparatus.
