Abstract
A weld-free heat exchanger assembly core includes a plurality of stacked fin-plate assemblies. A separate enclosure bar is positioned at the end of each fin-plate assembly. A plurality of apertures are pre-drilled in the enclosure bars before assembly of the core. Once the core is assembled, it is brazed to form a unitary structure. Apertures formed in the inlet and outlet manifolds are aligned with apertures formed in the enclosure bars and fasteners are inserted into the aligned apertures. The fasteners serve to draw each manifold into tight engagement with a plurality of separate enclosure bars.
