Abstract:
1. A heat-exchanger assembly comprising: first and second manifolds; and a plurality of tubes extending between said first and second manifolds to define a first fluid pass through the heat-exchanger, each of said tubes have a generally wedge-shaped cross-sectional configuration which tapers outwardly in a direction along an axis extending along the width of each said coolant tubes, each said tube defining a plurality of flow passages extending along the length of the tube for carrying fluid through the first pass in parallel-flow relationship, said plurality of passages having substantially identical hydraulic diameters to promote uniform distribution of flow across the width of each tube through the first pass; wherein each of said tubes includes a pair of opposite walls which define expansive, heat-exchanging surfaces of each tube, each of said walls being of substantially uniform thickness.
