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.

[ What is claimed is:] [14.]14. An environmental control system, comprising:an air conditioning system; anda weld-free heat exchanger having an outlet connected to an inlet of the air conditioning system;said heat exchanger including a core assembly of substantially rectangular configuration and formed by a plurality of separate fin assemblies stacked upon one another;said heat exchanger further including a plurality of separate support plates, each support plate being positioned between and supporting a pair of adjacent fin assemblies;said heat exchanger further including a plurality of separate, substantially rectangular-shaped enclosure bars, each enclosure bar being secured to an end of each fin assembly, each enclosure bar including a pair of enlarged end portions, each end portion having at least one aperture extending therein;said heat exchanger further including a separate manifold positioned adjacent each side of said core assembly, wherein each pair of manifolds and said core form a plurality of fluid flow passageways through said heat exchanger assembly; andthe manifolds being mechanically fastened to said enclosure bars.
