Claim:
1. A plate fin heat exchanger comprising: a plate fin core having a plurality of plates defining a set of hot air passages extending from a hot air inlet region of the plate fin core to a hot air outlet region of the plate fin core and a set of cool air passages extending from a cool air inlet region of the plate fin core to a cool air outlet region of the plate fin core, wherein the hot air inlet region of the plate fin core is disposed at a first side of the plate fin core, wherein the hot air outlet region of the plate fin core is disposed at a second side of the plate fin core opposite the first side of the plate fin core, wherein the cool air inlet region of the plate fin core is disposed at a third side of the plate fin core that is orthogonal to the first and second sides of the plate fin core, and wherein the cool air outlet region of the plate fin core is disposed at a fourth side of the plate fin core that is opposite the third side and orthogonal to the first and second sides of the plate fin core; and a mounting flange circumscribing the cool air outlet region at the fourth side of the plate fin core the mounting flange defined by first and second parallel legs and third and fourth parallel legs that are perpendicular to the first and second legs, at least a portion of the mounting flange having a plurality of heat transfer structures that extend into a flow path of cooling air exiting the cool air outlet region of the plate fin core, wherein the plurality of heat transfer structures of the mounting flange are comprised on the first leg of the mounting flange which extends along an intersection of the first and fourth sides of the plate fin core.
