Abstract
A manifold for a heat exchanger comprising a tank, a plurality of tubes arranged to receive fluid therein, a plurality of fins for interspacing the tubes, the fins extending along the length of the tubes to thereby define a core section, wherein the header section is formed with multi-point brazing interfaces for securing said header and said core section during a brazing process. One embodiment provides at least one doubled wall area in close proximity to the tube slot areas to form a structure of increased strength, permitting the material to be reduced in relative thickness. The manifold may be formed from flat sheet stock by extended side walls of the header portion joined by a separate cap to close a top portion of the manifold assembly for the purpose of collecting fluid to and from the tubes and said at least one inlet and outlet. For a plastic manifold, the header section is formed with an inner wall defining an extended tube slot area of a header well to receive the plastic tank foot portion thereby increasing the strength of the structure.
