an inlet plenum housing defining an inlet plenum configured to receive a fluid;
an outlet plenum housing defining an outlet plenum configured to discharge the fluid from the heat exchanger;
a core configured to heat or cool a first portion of the fluid, the core defining a plurality of fluid passages fluidly coupled to and extending from the inlet plenum to the outlet plenum;
a passive bypass defining a passive bypass flow path fluidly coupled to and extending between the inlet plenum and the outlet plenum, the passive bypass flow path being in parallel with at least a portion of the core such that a second portion of the fluid bypasses at least a portion of the core and flows continuously and unobstructed through the passive bypass flow path to the outlet plenum; and
a baffle partially defining the passive bypass flow path;
wherein the outlet plenum and the inlet plenum are positioned adjacent one another, such that the inlet plenum, the outlet plenum, and the passive bypass share a common wall, and the baffle, the passive bypass, and the inlet plenum each extend from an upstream inlet cross-section of the inlet plenum housing.
