SECONDARILY APPLIED COLD SIDE FEATURES FOR CAST HEAT EXCHANGER

摘要

A heat exchanger (10) includes a primary plate (22; 64) including a first surface (40), a second surface (42), a leading edge (36), a trailing edge (38) and a plurality of internal passages (30; 76) extending between an inlet (32; 72) and an outlet (34; 74). A secondary plate (24; 66) is attached to at least one of the first surface (40) and second surface (42) of the primary plate (22; 64). The secondary plate (24; 66) includes heat transfer structures. A method is also disclosed.
