Abstract: A method of extending the lifetime of brazed primary hot inlet wavy fin structures of aircraft heat exchangers includes inserting slots in the fins. The slots increase the mechanical compliance of the fins as well as act as crack arrestors should a thermally induced fracture occur. In an embodiment, the slots are inserted by EDM.

Abstract: A heat exchanger assembly for an inert gas system includes a ram air inlet flange, a ram air outlet flange, and a core coupled to the ram air inlet flange and the ram air outlet flange. The core includes a fin assembly having a plurality of hot layers and ram air layers. The hot layers have an effective hot flow length, the ram air layers have an effective cold flow length, and the fin assembly has a no flow length. A ratio of the effective hot flow length to the effective cold flow length is between 9.23 and 10.32. A ratio of the no flow length to the cold flow length is between 21.86 and 25.23.
