Benefits of technology
"The present invention provides heat exchanger assemblies that can function under high temperature and pressure conditions, while still using cost-effective materials. The assemblies use a tank with a rigid neck that is reinforced with fiber reinforced plastic resin or other materials like cast metal or formed sheet metal. The neck can have one or more ribs or grooves to improve strength and resistance to deformation. The hose-neck connection uses a hose design that does not require a specific hose design to avoid crushing, and the dimensions of the neck remain unaffected when the hose and neck are assembled. The invention also provides improved neck rigidity without adding significantly to the overall packaging volume or cost of the tank and molding tool."
Problems solved by technology
Other, more elaborate connection schemes that do not rely on clamping pressure, such as quick-connects, will avoid the neck deformation problem, but are significantly more expensive than traditional clamped connections.

Embodiment Construction
[0029]In various aspects of the present invention, a heat exchanger assembly comprising: a core comprising a tube or tubes; a manifold, a hose having flexible attachment area for attachment to a manifold neck; a manifold neck of greater relative stiffness when compared to the hose, which serves as a fluid inlet or outlet on the manifold; and at least two ribs on the part of the manifold neck that extends into the environment exterior to the manifold is disclosed. In various aspects, at least one of the at least two ribs on the manifold neck is a circumferential or essentially circumferential rib; and wherein the hose, neck and ribs form a hose-neck connection comprising sealing surfaces which form a hose to neck seal that is essentially leak tight to the exterior of the heat exchanger.
[0030]Aspects of the present invention include heat exchangers assembly comprising a hose bead on the manifold neck, such that the sealing surfaces maintain an essentially leak tight seal while helping...

A heat exchanger assembly comprising a heat exchanger with tank having a neck, and, in various embodiments, an assembly further comprising a hose to form a hose-neck connection is provided.A heat exchanger assembly comprising a hose-neck connection, having the advantage of providing for a connection resistant to temperature and pressure conditions of heat exchangers is provided.By providing for particular rib patterns on the neck, an optimized rib pattern can be found based on the environmental conditions and use of the heat exchanger assembly.
Description
FIELD OF THE INVENTION[0001]The present invention relates to automotive heat exchangers, in particular, those with tank and hoses connected to the tank by an inlet or outlet.BACKGROUND OF THE INVENTION[0002]Automotive heat exchangers typically use hoses, and, particularly, flexible hoses that can be attached to a heat exchanger tank. The flexible hoses are often attached by sliding the end of the hose over the neck of the tank.[0003]A problem with such a hose connection has been the need for a stop or limiter, to limit the distance the hose can slide over the neck. A raised portion of the neck outer surface has been used to act as a “hose-stop” as one solution to this problem. A circumferential raised portion at the open end of the neck has also been used, which acts as a “hose-bead”. The hose-bead acts to seal and retain the hose-neck connection.[0004]A third possible solution to hose placement problems has been the use of a clamping device, and, in particular, a hose-clamping devi...
