1. A heat exchanger comprising:
- a plate portion including a plurality of internal passages extending between an inlet and an outlet, wherein the plate portion is a one piece cast part including a plurality of cast fins extending from an outer surface; and
a plurality of crossover passages for providing fluid communication between adjacent ones of the plurality of internal passages between the inlet and the outlet, wherein the plurality of crossover passages are distributed in a non-uniform manner with a greater number of crossover passages provided closer to the inlet than to the outlet such that more crossover passages are disposed within a first length from the inlet that is no more than 15% of a total length between the inlet and the outlet than are disposed after the first length.

12. A cast heat exchanger plate comprising:
-
a one piece cast plate portion including a plurality of cooling fins extending from an outer surface; at least one internal wall defining at least two internal passages extending between an inlet and an outlet within the cast plate portion; and a plurality of crossover passages extending through the internal wall providing fluid communication between the at least two internal passages, wherein the plurality of crossover passages are distributed in a non-uniform manner with a greater number of crossover passages provided closer to the inlet than to the outlet such that more crossover passages are within a first length from the inlet that is no more than 15% of a total length between the inlet and the outlet than are disposed after the first length. - View Dependent Claims (13)

14. A core assembly for a heat exchanger comprising:
-
at least one core plate defining internal features of a heat exchanger plate portion, the core plate including passage defining features disposed between gaps defining at least one internal wall between at least two internal passages; and a plurality of crossover features between the passage defining features for defining a plurality of crossover passages through the internal wall providing fluid communication between the at least two internal passages, wherein the plurality of crossover passages comprises a plurality of crossover features arranged between ends of the passage defining features and more of the plurality of crossover features are distributed in a non-uniform manner with a greater number of crossover passages provided closer to the inlet than to the outlet such that more crossover passages are provided within a first length from a first open end that is no more than 15% of a total length between open ends. - View Dependent Claims (15, 16, 17, 18, 19)
