Abstract
A manifold assembly for use with heat exchangers comprises an extruded unitary tank having a substantially U-shaped cross-section and a unitary stamped header plate which can either be substantially planar or have a substantially U-shaped cross-section. The longitudinal bottom edges of the tank are crimped around the longitudinal side edges of the header plate, and the mating surfaces are brazed substantially along their entire lengths. The inner wall of the tank can include opposed longitudinal ribs having opposed slots therein for receiving baffles for adjusting the flow path within the assembled manifold. The tank, header plate, and baffles are formed of aluminum and aluminum alloy materials suitable for furnace brazing, at least one of the mating surfaces being fabricated with a lower temperature clad brazing material, so that when the tank, header plate, baffles and heat exchanger tubes are assembled, fixtured, and brazed in a high temperature brazing furnace, the clad material provides the brazed material to braze the tubes to the header plate, the header plate to the tank, the baffles to the tank and the header late.
