Filed:

Feb 23, 2007

Appl. No.:

11/710191

Inventors:

David E. Samuelson - Wheatfield NY, US
Donald Robert Pautler - Lockport NY, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F28F 9/00
F28D 7/06

US Classification:

165 68, 165176

Abstract:

An core unit for a heat exchanger being bent about an axis perpendicular to the core unit's headers. Tubes establish fluid communication between the core unit's headers, and a bend relief spacer is disposed between first and second groups of tubes. During the bending process, the bend relief spacer facilitates the bend and ultimately maintains the performance of the core unit.

International Classification:

B23P 15/26
F28F 9/02

US Classification:

29890043, 29890052, 165174

Abstract:

A heat exchanger assembly includes an outlet header extending along an outlet axis to define an outlet cavity and an inlet header defining an inlet cavity. A plurality of refrigerant tubes extends from the inlet header through the outlet header and into the outlet cavity. A collector conduit having a generally semi-circular conduit cross-section defining an arced surface and a chord surface interconnected with rounded ends is disposed in the outlet header and includes a conduit body portion and at least one conduit end portion interconnected by a conduit transition portion with the conduit body portion being offset from the conduit end portion. The conduit body portion is engaged to an interior surface of the outlet header to space the conduit body portion from the refrigerant tubes and the conduit end portion is coaxial with the outlet header axis to provide a central outlet for the refrigerant vapor.

International Classification:

F28F 9/02
F28F 9/04

US Classification:

165174, 165178

Abstract:

A heat exchanger assembly that includes an outlet header/manifold defining an outlet cavity, an outlet tube in fluidic communication with the outlet cavity, and a heat exchanger core. The outlet tube and the outlet cavity cooperate to reduce a temperature value range across the heat exchanger core by equalizing refrigerant distribution between the refrigerant tubes within the heat exchanger core. The length of the heat exchanger headers/manifolds may be increased for a predetermined packaging width because the outlet tube and inlet conduit may exit the headers/manifolds perpendicularly rather than axially, allowing the heat exchanger core width to be increased. The increased heat exchanger core width allows additional refrigerant tubes to be included in the heat exchanger core, providing decreased air pressure difference for air flowing through the heat exchanger assembly and increased heat capacity of the heat exchanger assembly.

Abstract:

A communication plate extends along and is sandwiched between cylindrical communication manifolds of a first heat exchanger assembly and a second heat exchanger assembly. The communication plate includes a saddling surface arcuate in one direction and a saddling surface arcuate in the opposite direction for engaging in saddle-like fashion the cylindrical shape of the manifolds. The communication plate defines a plurality of communication plate orifices disposed along the communication plate and aligned co-axial with a plurality of communication orifices disposed along the manifolds to seal the communication orifices of the manifolds and establish distributed and sealed fluid communication between the heat exchanger assemblies.

Abstract:

A method for fabricating a heat exchanger assembly () includes pressing a pair of headers () into refrigerant tubes (). A notch () is cut axially into header ends (). An inner radial abutment () is formed in each of the refrigerant conduits (), which are then each inserted through an open end cap (). An outer radial abutment () is formed in each of the refrigerant conduits () so that the open end caps () are retained in position between the radial abutments (). The radial abutments () can comprise a bead, a radially inwardly extending shoulder, an outwardly extending shoulder, or an expansion beneath the open end caps (). A tool presses each subassembly into the corresponding headers () until the tool reaches the corresponding notch bottom ().

International Classification:

B21D 53/02

US Classification:

2989003

Abstract:

An improved bending apparatus for bending a radiused corner at a window in a brazed heat exchanger core where no tubes and fins are located. A cylindrical mandrel and sliding pressure die are designed to completely surround the manifold in the areas of the window and provide a continuous, rolling contact area or profile support around the manifold as the bending moment is applied.
