ABSTRACT:
An automotive radiator reduces coolant pressure drop with a novel flow turning structure integrally molded into the inlet header tank, opposite the inlet pipe. A pair of compound curved surfaces, sloping toward opposite directions from a crest edge, split and divide the flow leaving the inlet pipe and send it proportionately toward opposite ends of the tank, smoothing out the flow transition and reducing the attendant pressure loss. The curved surfaces also have a component of curvature toward the flow tubes, as well as being sloped toward opposite ends of the tank.
