Abstract

A heat exchanger is provided including a first manifold, a second manifold, and a plurality of heat exchange tube segments fluidly coupling the first and second manifold. The heat exchange tube segments include a bend defining a first slab and a second arranged at an angle to one another. Each of the heat exchange tube segments includes at least a first heat exchange tube and a second heat exchange tube at least partially connected by a web extending there between. The first heat exchange tube and the second heat exchange tube are asymmetrical such that a cross-sectional flow area of the first heat exchange tube is different than that of the second heat exchange tube. A fluid flows sequentially through the first heat exchange tubes of the first slab and the second slab, and then through the second heat exchange tubes of the second slab and first slab.
