Heat exchanger having compliant manifolds

A heat exchanger comprising:

• a) a core including a plurality of parallel layered flow passages for accommodating a first fluid flow having a first temperature, and a plurality of layered cross-flow passages in thermal communication with the layered flow passages for accommodating a second fluid flow having a second temperature lower than the first temperature;
• b) an inlet manifold operatively associated with an inlet side of the core and including a fluid inlet to receive the first fluid flow, a manifold wall extending along a longitudinal axis and including a plurality of integrally formed longitudinally spaced apart wall segments that are each separated from one another by a shaped expansion joint, and an interface with the core that includes an array of inflow ports in fluid communication with the layered flow passages of the core;
• and
• c) an outlet manifold operatively associated with an outlet side of the core and including a fluid outlet for egress of the first fluid flow, a manifold wall extending along a longitudinal axis and including a plurality of integrally formed longitudinally spaced apart wall segments that are each separated from one another by a shaped expansion joint, and an interface with the core that includes an array of outflow ports in fluid communication with the layered flow passages of the core,
• wherein:
• the manifold wall of each manifold has a crescent-shaped configuration in a cross-section taken transverse to the longitudinal axis, the crescent-shaped configuration having a first end and a second end;
• and
• the crescent-shaped manifold and core cooperate to surround an open volume, the open volume being open at a pair of axial ends of the open volume.
