Abstract

A heat exchanger module adapted for being mounted directly to the outer surface of the housing of an automobile system component, such as a transmission or engine housing, is provided. The heat exchanger module has a heat exchanger fixedly attached to an adapter module. The adapter module contains one of more fluid transfer channels and includes a portion that extends outwardly beyond the footprint of the heat exchanger. The adapter module is comprised of a first embossed plate that is sealed with a second plate, which may also be embossed. The embossments provide fluid transfer channels and also perform as structural ribs to enhance the rigidity of the adapter module.

First claim

What is claimed is:

1. A heat exchanger module for mounting directly to the outer surface of a housing of an automobile system component, the heat exchanger module comprising:
a heat exchanger comprising a plurality of stacked heat exchange plates defining alternating first and second fluid flow passages through said heat exchanger, the heat exchanger having a footprint corresponding to an area defined by the stack of heat exchange plates;
a pair of first fluid manifolds extending through the heat exchanger and coupled to one another by the first fluid flow passages, the pair of first fluid manifolds comprising an inlet manifold and an outlet manifold for the flow of a first fluid through said heat exchanger;
a pair of second fluid manifolds extending through the heat exchanger and coupled to one another by the second fluid flow passages, the pair of second fluid manifolds comprising an inlet manifold and an outlet manifold for the flow of a second fluid through said heat exchanger;
an adapter module having a first surface and an opposite second surface, wherein the first surface of the adapter module is attached to an end of the heat exchanger within the footprint of the heat exchanger, and wherein the second surface is adapted for direct face-to-face contact with an interface surface on the outer surface of the automobile system component housing, and wherein the adapter module has a length and a width and includes a portion that extends outwardly beyond the footprint of the heat exchanger;
the adapter module comprising:
a second fluid inlet port on the second surface of the adapter module and outside the footprint of the heat exchanger, the second fluid inlet port being adapted for receiving the second fluid from an outlet port of the automobile system component housing;
a second fluid outlet port on the second surface of the adapter module and outside the footprint of the heat exchanger, the second fluid outlet port being adapted for discharging the second fluid to an inlet port of the automobile system component housing;

a first fluid transfer channel formed in the adapter module for allowing fluid communication between a first one of the second fluid manifolds and the second fluid inlet port or the second fluid outlet port;
wherein the adapter module further comprises:
a first adapter plate having a first surface and an opposed second surface, the first surface of the first adapter plate defining the first surface of the adapter module, and through which the adapter module is attached to the end of the heat exchanger; and
a second adapter plate having a first surface and a second surface, the first surface of the second adapter plate fixedly attached to the second surface of the first adapter plate, and the second surface of the second adapter plate defining said second surface of said adapter module;
wherein the first fluid transfer channel is formed between the first and second adapter plates;
wherein the first fluid transfer channel comprises a first trough portion which projects from the second surface of the second adapter plate;
wherein the first trough portion is elongate, and extends along at least a portion of the length of the adapter module and/or along at least a portion of the width of the adapter module; and
wherein the first trough portion has a first end and a second end, the first trough portion extending continuously between the first and second ends thereof, the first end being within the footprint of the heat exchanger and aligned with a first fluid port formed on the first adapter plate, the first fluid port being aligned with said one of the second fluid manifolds, and wherein the second end of the first trough portion is outside the footprint of the heat exchanger and aligned with said second fluid inlet or outlet port.

2. The heat exchanger module of claim 1 , wherein the first trough portion comprises an embossed rib and is integral with the second adapter plate.

3. The heat exchanger module of claim 1 , wherein the plurality of stacked heat exchange plates comprises a plurality of core plates, a top plate, and a bottom plate, wherein the bottom plate has a bottom surface which defines the end of the heat exchanger to which the first surface of the adapter module is attached.

4. The heat exchanger of claim 3 , wherein the core plates are identical to one another, and wherein the bottom plate has at least the same shape and thickness as the core plates.

5. The heat exchanger of claim 3 , wherein the bottom plate and each of the core plates has four conduit openings, and wherein the bottom plate and the core plates are identical to each other.

6. The heat exchanger of claim 1 , further comprising a second fluid transfer channel formed in the adapter module for allowing fluid communication between a second one of the second fluid manifolds and the other one of the second fluid inlet port and the second fluid outlet port;
wherein the second fluid transfer channel is formed between the first and second adapter plates;

wherein the second fluid transfer channel comprises a second trough portion which projects from the second surface of the second adapter plate;
wherein the second trough portion comprising the second fluid transfer channel is elongate, and extends along at least a portion of the length of the adapter module and/or at least a portion of the width of the adapter module; and
wherein the second trough portion comprises a second embossed rib and has a first end and a second end, the second trough portion extending continuously between the first and second ends thereof, the first end being within the footprint of the heat exchanger and aligned with a second fluid port formed on the first adapter plate, the second fluid port being aligned with another of the second fluid manifolds, and the second end being outside the footprint of the heat exchanger and aligned with said second fluid inlet or outlet port.

7. The heat exchanger module of claim 6 , further comprising:
a third trough portion formed in the second adapter plate, the third trough portion having a first end and a second end, the third trough portion extending continuously between the first and second ends thereof, the first end being within the footprint of the heat exchanger and aligned with a first fluid inlet port formed on the first adapter plate, and the second end being outside the footprint of the heat exchanger and aligned with the first fluid inlet manifold of the heat exchanger, wherein the third trough portion projects from the second surface of the second adapter plate, wherein the third trough portion extends along at least a portion of the length of the adapter module and/or at least a portion of the width of the adapter module, and wherein the third trough portion comprises a third embossed rib;
a fourth trough portion formed in the second adapter plate, the fourth trough portion having a first end and a second end, the fourth trough portion extending continuously between the first and second ends thereof, the first end being within the footprint of the heat exchanger and aligned with a first fluid outlet port formed on the first adapter plate, and the second end being outside the footprint of the heat exchanger and aligned with the first fluid outlet manifold of the heat exchanger, wherein the fourth trough portion projects from the second surface of the second adapter plate, wherein the fourth trough portion extends along at least a portion of the length of the adapter module and/or at least a portion of the width of the adapter module, and wherein the fourth trough portion comprises a fourth embossed rib.

8. The heat exchanger module of claim 6 , wherein the first adapter plate further comprises:
third and fourth flu
