Abstract: Heat exchanger assemblies, and in particular, heat exchanger assemblies for automotive vehicle applications are disclosed. The heat exchangers have manifolds with retention tabs for brackets, caps and other components, such as attachment elements.

Abstract: A gasket and method for detecting the status of an installed gasket is disclosed, wherein the gasket comprises a series of protruding projections which vary from a visually detectable, defined direction when installed improperly. This invention has particular utility in manufacturing operations where improper gasket installation is difficult to detect during assembly, particularly in the automotive heat exchanger industry.

Abstract: This invention is to an improved method for reducing crevice corrosion in assembly joints of aluminum fluid handling devices, the improvement comprising, providing a series of spaced ribs at the assembly joint configured to intermittently resist engagement of components along an elongated assembly crevice sufficient to segment the crevice into a plurality of minor assembly crevices dimensioned to permit substantial mixing of fluid within the minor crevices with fluid being handled by the device. The invention has particular utility in automotive heat exchangers wherein crevices at joints where polymeric tanks are assembled to aluminum metal headers are susceptible to crevice corrsion.
