A method for making a manifold for a tube and fin type heat exchanger wherein the manifold is a one piece aluminum extrusion. The manifold includes a U-shaped channel having a base member and a pair of vertical walls, a plurality of fluid conducting passageways in the base member, and a pair of hollow longitudinal fluid conduits. The conduits are then crimped at predetermined locations to form fluid baffles and the manifold is then sealed. The baffles include slits which allow a bonding agent to secure the baffle within the fluid conduit.

[ What is claimed is:] [1.] A method of making a manifold for a heat exchanger, comprising the steps of:extruding a piece of plastically deformable material into a longitudinal U-shaped channel having a generally planar base member and a pair of vertically depending walls projecting generally perpendicularly to the plane of said base member;forming a plurality of fluid conducting passageways in said base member;rolling said vertical walls toward the longitudinal center of said base member until the free ends of said walls contact said base member so as to form a pair of hollow longitudinal fluid conduits; andforming a baffle in at least one of the longitudinal fluid conduits by plastically deforming a top wall of at least one of said fluid conduits until said top wall abuts a bottom wall of said fluid conduit and bonding said top wall to said bottom wall thereat, said step including providing a slit in said top wall and causing a bonding material to flow therethrough.
