Abstract
A heat exchanger includes a first manifold, aa second manifold, at least one heat exchange tube segment extending between and fluidly coupling the first manifold and the second manifold, and a fin having a non-linear configuration. A portion of the fin is affixed to an adjacent surface of the at least one heat exchange tube segment via a braze joint. The braze joint has a length, measured parallel to a length of the at least one heat exchange tube segment, less than or equal to 650 micrometers.
