Abstract:
1. A heat exchanger assembly comprising: a first manifold extending along an axis; a second manifold extending along an axis in spaced and parallel relationship with said first manifold; each of said manifolds including a pair of manifold ends spaced from each other; each of said manifolds having a tubular wall extending between said manifold ends to define a flow path; said tubular wall of each of said manifolds defining a plurality of tube apertures being spaced from each other; a plurality of flow tubes extending between said tube apertures of said manifolds and in fluid communication with said flow paths for communicating a heat exchange fluid between said manifolds; a plurality of air fins disposed between said flow tubes for increasing the surface area of said flow tubes; said tubular wall of said first manifold defining a plurality of spaced and opposing indentations; an insert disposed in and dividing said flow path of said first manifold and presenting a directing surface; and a pair of side flanges integrally connected to said insert and extending from said directing surface of said insert and along said tubular wall of said first manifold and engaging said indentations for orienting and securing said insert against rotation in said flow path of said first manifold.
