1. A heat exchanger configured for a power generation system, the heat exchanger comprising:

  • a. at least one plate assembly including a first end, a second end opposed to the first end along an axial direction, and at least one serpentine segment that extends between the first end and the second end, the at least one serpentine segment including a plurality of slot portions aligned along a lateral direction that is perpendicular to the axial direction and configured to permit thermal expansion and contraction of the at least one serpentine segment along the axial direction,wherein each plate assembly includes a plurality of plates stacked with respect to each other, the at least one plate assembly defining a first flow configuration and a second flow configuration that is separate from the first flow configuration, the first and second flow configurations extending from the first end to the second end along the at least one serpentine segment so as to direct first and second fluids, respectively, through the at least one plate assembly; and

    b. a casing assembly that applies a tension force to the at least one plate assembly along the axial direction, such that, when the at least one plate assembly is exposed to at least predetermined temperature, each plate expands at least partially along the axial direction so as to reduce the tension force applied to the plate assembly.
