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.
A heat exchanger for exchanging heat between at least a first fluid and a second fluid, the exchanger including at least one first plate means forming an inlet and outlet manifold means for the first fluid, at least one second plate means forming a fluid impingement plate means for the first fluid and a finned heat exchanger plate means for the second fluid, and at least one third plate means for forming an end manifold means, said fluid impingement plate means including a plurality of spaced orifice means for enabling a flow of the first fluid through said fluid impingement plate means, said at least one first, second and third plate means being stacked to form a laminated heat exchanger core, said end manifold means including means for deflecting the flow of the first fluid flowing in a first direction from said impingement plate means back toward an through said fluid impingement plate means in at least a second direction toward said inlet and outlet manifold means and a plurality of spaced recess means for forming channel means for the flow of the second fluid, and wherein said first and second directions are orthogonal to a flow direction of the second fluid through said finned heat exchanger plate means.
