1. A core assembly for a plate-and-fin heat exchanger, the core assembly comprising:
a pair of core plates defining a passageway; and
a heat-absorbing member disposed within the passageway defined by the pair of core plates, wherein the heat-absorbing member secures the pair of core plates together and defines a plurality of fins that each include a plurality of bending points, and each bending point is between two points of contact between a core plate and the heat-absorbing member, and wherein each of the plurality of bending points is an edge, and wherein each edge of the plurality of bending points cooperates with one another to define a trapezoidal toothed profile.
