Abstract
The present invention relates to the field of automotive heat exchangers, and, in particular, to ribbed heat exchanger tanks. This invention uses ribs that are oriented perpendicular to the local wall bending axes, and, therefore, not necessarily perpendicular to or parallel with the plane of the header to improve resistance to thereby reduce wall deflection and reduce stress concentration in or near the ribs.
Claims16
A heat exchanger for use in automotive applications, particular those uses in higher pressure internal environments, comprising a heat exchanger body part and a heat exchanger tank part comprising at least one non-uniform wall section, wherein the non-uniform wall section of the heat exchanger tank part is reinforced by the presence of at least one rib or ribs in a particular pattern.
A method of making a heat exchanger with a heat exchanger tank having angled ribs wherein synthetic resin or plastic or plastic-like materials have fibers or contour lines and is injected or otherwise formed make a heat exchanger tank so that the synthetic resin or plastic or plastic like material flows such that the fibers are aligned to follow the flow along the line of the ribs.
