Plate-type crossflow air-to-air heat-exchanger comprising side-by-side-multiple small-plates

A system for conditioning air streams, comprising:

• at least one fan for forcing air through said system,
• a first heat exchanger having an intake port, an exhaust port, and a plurality of heat conducting walls defining channels for passage of a first air stream from a first air stream intake port to a first air stream exit port and for passage of a second air stream from a second air stream intake port to a second air stream exit port;
• at least one other heat exchanger having an intake port, an exhaust port, and a plurality of heat conducting walls defining channels for passage of a first air stream from a first air stream intake port to a first air stream exit port and for passage of a second air stream from a second air stream intake port to a second air stream exit port;
• said first heat exchanger and said at least one other heat exchanger being secured to a frame;
• two manifold assemblies, each manifold assembly including triangular dividers and triangular ends, each manifold assembly further including at least one manifold exhaust port and/or at least one manifold intake port, said at least one manifold exhaust port and/or said at least one manifold intake port being disposed in the first air stream or in the second air stream or in both the first and second air streams and said triangular dividers and triangular ends are substantially perpendicular to said heat conducting walls of said heat exchangers.
