Asymmetric application of cooling features for a cast plate heat exchanger

Abstract

A cast plate heat exchanger includes a first surface including a first surface inlet end and a first group of augmentation features defining a first average density of augmentation features across the first surface. A second surface is in heat transfer communication with the first surface. The second surface includes a second surfaces inlet end and a second group of augmentation features defining a second average density of augmentation features across the second surface. A total augmentation feature density ratio is defined from the first average density of augmentation features to the second average density of augmentation features. A first region is shared by both the first surface and the second surface and covers at least a portion of the first surface inlet end. The first region includes a first region augmentation feature density ratio that is less than the total augmentation feature density ratio.
