Benefits of technology

[0007] An aspect of the present invention is to provide a manifold for a heat exchanger. The manifold has an elongate tubular body with a central cavity formed therethrough. The tubular body has an elongate retainer formed at least partially upon the body. An attachment member has an end received by the retainer, and an insert is retained between the tubular body and the attachment member. The insert is formed from a material having a melting temperature that is less than that of the tubular body and the attachment member.
[0008] Another aspect of the present invention is to provide a method for manufacturing a manifold for a heat exc

Problems solved by technology

Clad sheets are relatively costly to fabricate requiring a billet of the clad layer placed upon a billet of the structural layer with multiple cold forming operations to result in the final clad sheet.

Embodiment Construction

[0020] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and / or as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0021] Referring now to FIG. 1, a simple vapor-compression cycle is illustrated and referenced generally by numeral 20. The cycle 20 includes a compressor 22, such as a pump, which pumps fluid through the cycle 20 in the direction of the arrows illustrated in the figure. The compressor 22 pumps the fluid to a first heat exchanger, illustrated by c...

Abstract

Manifolds and manifold connections for heat exchangers are disclosed. One embodiment includes an elongate tubular body with a central cavity. The body has an elongate retainer formed therealong. An attachment member is received by the retainer and an insert is retained between the tubular body and the attachment. The insert is formed from a material having a melting temperature less than that of the tubular body and the attachment member. The manifold may be heated to a temperature greater than the melting temperature of the insert material and subsequently cooled so that the insert joins the attachment member to the body.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to heat exchangers, more particularly to manifolds and manifold connections of heat exchangers. [0003] 2. Background Art [0004] Heat exchangers generally are units wherein a first fluid is conveyed in close proximity to a second fluid of a different temperature, such that heat is exchanged from one fluid to another. Heat exchangers generally include condensers, evaporators, radiators, oil coolers and heater cores, which employ manifolds that are utilized for conveying a fluid therein. The manifolds are typically formed from a material that is both conductive and structurally adequate to retain the fluid therein for an exchange of heat to or from a fluid external of the manifold. [0005] An aspect of the prior art is to form manifolds from clad sheets of aluminum that include a first layer of American National Standards Institute (ANSI) designation such as 3003, and a second layer with an ANSI de...
