Lateral plate finned heat exchanger

A stacked plate heat exchanger comprising:

• 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 having spaced apart inlet and outlet openings in flow communication with the fluid passage, at least some of the plate pairs having a substantially plate 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;
• wherein the central portions are substantially planar and have a first plurality of obliquely orientated, parallel ribs formed thereon, the ribs of the first and second plates in each plate pair cooperating to form at least a portion of the fluid passages in back-to-back plates of adjacent plate pairs and for each plate pair having a fin plate, the plate pair has elongate, parallel spaced apart first and second edges, the fluid passage being located between the spaced apart first and second edges and extending at an angle that is non-parallel to the first and second edges, and the ribs on at least one of the first and second plates are orientated to be close to parallel to the first and second edges.
