ABSTRACT:
A heat exchanger for exchanging heat between at least a first fluid and a second fluid, with the heat exchanger including an intake and outlet manifold (10, 11, 12, 13) for a first fluid, at least one fluid impingement plate and finned heat exchanger plate (14) for the second fluid, and an end plate manifold, with the plates being stacked so as to form a laminated heat exchanger core. At least one or more spacer plates (15) may be interposed between the respective plates of the heat exchanger core and/or the inlet and outlet manifold (10, 11, 12, 13) and end manifold (18). The first fluid is fed into the inlet and outlet manifold (10, 11, 12, 13) and flows in a first direction through the impingement and finned heat exchanger plates (14) and is redirected by the end manifold (18) toward the inlet and outlet manifold (10, 11, 12, 13). The inlet and outlet manifold (10, 11, 12, 13) and the end manifold (18) are constructed so as to enable a multiple directional change in the flow of the first fluid through the heat exchanger core, with the changes in the flow direction of the first fluid being substantially parallel and orthogonal with respect to the flow of the second fluid through the heat exchanger core.
