A stacked plate heat exchanger including a plurality of stacked plate pairs,
each
plate pair including first and second plates having elongate central portions surrounded
by sealably joined edge portions with an elongate fluid passage defined between
the central portions. Each plate pair has spaced apart inlet and outlet openings
in flow communication with the fluid passage, at least some of the plate pairs
having a substantially planar air-side fin plate extending peripherally outward
from the joined edge portions, the fin plates of the stacked plate pairs being
spaced apart and substantially parallel to each other. The fluid passage may be
arranged at an angle relative to air flow direction.
