  • Evaporator having integrally baffled tubes
    Patent number: 5090477
    Abstract: A tubular manifold for an evaporator includes an integral baffle formed by deforming a wall section of a header tube onto an opposing wall section and crimping the two side walls inwardly at an axial point where the wall section is deformed. The internal baffle forms a U-shaped seal within the tube and is interposed between two side ports of the manifold.
