Abstract
A heat exchanger is formed by a pair of tank units with a core therebetween. The core comprises a plurality of tube passes extending between and in fluid communication with the tank units, and air centers connected between the tube passes in conductive heat transfer with air and the flow passes. The tank units are formed by separate tanks and headers. The tanks and headers include a flat, coplanar perimeter flange extending thereabout. The flanges include locking members therethrough to secure the header to the tank. The locking members may comprise longitudinal projections formed through the tank flange projecting through the header flanges, or alternatively aligned apertures in the flanges with plug inserted therethrough.
