ABSTRACT:
A manifold and a method of making a manifold for a tube and fin type heat exchanger are disclosed wherein the manifold is a one piece aluminum extrusion. The method includes the steps of extruding the material into a U-shaped channel having a base member and a pair of vertical walls, forming a plurality of fluid conducting passageways in the base member, and rolling the vertical walls toward the longitudinal center of the base member until the free ends of the walls contact the base member to form a pair of hollow longitudinal fluid conduits. The conduit are then crimped at predetermined locations to form fluid baffles and the manifold is then sealed.
