Abstract
A cast plate heat exchanger includes an inner surface of a passage with a first group of augmentation features with a first density across the inner surface. An outer surface includes a second inlet end and a second group of augmentation features arranged with a second density across the outer surface. The first density and second density of augmentation features are located in a targeted manner to reduce thermal stresses.
