Abstract

A heat exchanger manifold for use in heat exchanger used mainly in automobiles is provided. The manifold comprises of two components a header and tank. The header consists of several half cylinders that have ferrule openings and communication port stamped on them. The communication ports are in form of channels that coincide with the ferrule opening. The ferrule openings allow the heat exchanger tubes to slide into the manifold and without any interference. The second component of the manifold comprises a tank. Like the header the tank also consists of several half cylinders, which combined with the header forms several full cylinder. The tank also includes an integral seal along the mating end of the manifold. The manifold also contains a unique inlet/outlet port that allows for ease of assembly of the final heat exchanger.

Dependent claims

A two piece heat exchanger manifold for a vehicle comprising:

a header wherein said header is formed of a first set of half cylinders;
an upwardly extending wall joining said first set of half cylinders;
an outwardly extending header wall surrounding said first set of half cylinders;
a tank coupled on top of said header wherein said tank is formed of a second set of half cylinders;
an outwardly extending tank wall surrounding said second set of half cylinders;
said header further comprising a third set of half cylinders extending from said outwardly extending header wall, wherein said third set of half cylinders are perpendicular to and intercepts said first set of half cylinders;
said third set of half cylinders having a single ferrule opening, wherein said ferrule opening substantially extends between opposing said outwardly extending header walls along a substantial length of said third set of half cylinders and said ferrule opening is perpendicular to said first set of half cylinders;
wherein said outwardly extending header wall and said outwardly extending tank wall mate to form a mating edge for said header and said tank;
and
wherein said second set of half cylinders is configured to mate with said first set of half cylinders upon coupling of said tank on top of said header to form a set of complete cylinders.
