Heat exchanger sealed tank and header assembly with gasket displacement prevention

摘要

A radiator tank of the type that has a perimeter foot clinched into a U shaped header plate channel to compress an elastomer seal is improved with a means to help assure that portions of the gasket that are displaced from beneath the foot at installation either do not create leak paths, or create leak paths that are static and easier to detect. Integrally molded discrete ribs above the bottom of the perimeter foot extend out and over the inner surface of the header plate, in a location where they can engage and pinch displaced portions of the gasket down against the header plate. Leaks are thereby either prevented, or, at least, the displaced and pinched down section of the gasket is held fast and prevented from moving in and out of the crevice between the tank foot and the channel under the influence of negative to positive pressure variations in the coolant. This makes leak detection easier, because the leak is static and consistent.
