1. A heat exchanger comprising:
a heat exchanger core;
a pressure housing at least partially defining a core chamber; and
a flex beam extending between and connecting the heat exchanger core and the pressure housing such that the heat exchanger core is suspended away from the pressure housing within the core chamber by the flex beam, the flex beam including a core end connected to the heat exchanger core and a housing end spaced along the flex beam from the core end and connected to the pressure housing;
wherein a radially inner edge of the flex beam is convex at a first point disposed between the housing end and the core end and a radially outer edge of the flex beam is concave at the first point; and
wherein the radially inner edge of the flex beam is concave at a second point disposed between the housing end and the core end and the radially outer edge of the flex beam is convex at the second point.
