Abstract:
A counter-flow recuperator formed from annular arrays of recuperator core segments. The recuperator core segments (38) are formed from two opposing sheets (40, 42) of fin fold material coined to form a primary surface zone (74) disposed between two flattened manifold zones (70, 72). Each primary surface zone has undulating corrugations (79) including a uniform, full height central portion (84) and a transition zone (86) disposed between the central portion and one of the manifold zones. A construction of recuperator core segments is provided which insures proper assembly of the components of the recuperator core segment, and of a plurality of recuperator core segments.
