US Patent 11255615 Heat exchanger flexible manifold

A heat exchanger is provided. The heat exchanger includes a core that receives a plurality of mediums. The heat exchanger includes a manifold. The manifold includes a first end that receives a first medium of the plurality of mediums. The manifold includes a second end that intersects the core at a manifold/core interface. The manifold includes a plurality of individual layers that provide gradual transitions for the first medium from the first end to the second end to reduce or eliminate discontinuities at the manifold/core interface that cause stress to the heat exchanger.
