Abstract

A housing for an aftertreatment system is disclosed. The housing includes a wall that defines an interior cavity. The interior cavity is configured to enclose at least one aftertreatment component. Moreover, the wall has at least one corrugated panel having alternating grooves and ridges.

First claim

What is claimed is:

1. A housing for an aftertreatment system, the housing comprising:
a plurality of single-layer, rectangular, exterior walls defining a generally rectangular interior cavity configured to enclose at least one aftertreatment component, at least one of the exterior walls comprising at least one corrugated panel having alternating grooves and ridges; and
a frame formed by a plurality of beams, the frame supporting the plurality of exterior walls,
wherein each alternating ridge of the at least one corrugated panel includes a raised wall, the raised wall including one or more extension portions that extend in opposite directions from each other, each said extension portion overlapping and contacting a corresponding one of the plurality of beams,
wherein at least one of the extension portions overlaps and contacts at least two sides of one of the beams of the plurality of beams of the frame,
wherein said at least one extension portion includes a bent edge that wraps around and engages said one of the beams, and
wherein the raised wall extends from one side of the exterior wall to the other side of the exterior wall opposite the one side.

2. The housing of claim 1 , wherein the at least one corrugated panel is integrally formed with the at least one of the exterior walls.

3. The housing of claim 1 , wherein the at least one corrugated panel runs along one of a length or a breadth of the at least one of the exterior walls.

4. The housing of claim 1 , wherein each alternating groove of the at least one corrugated panel is U-shaped including a base wall and a pair of side walls, and wherein for each alternating ridge of the at least one corrugated panel the raised wall is spaced apart from the base wall.

5. The housing of claim 4 , wherein the base wall is parallel to the raised wall and the pair of side walls is at right angles to each of the base wall and the raised wall.

6. The housing of claim 1 , wherein each beam of the plurality of beams includes a square shaped cross-section.

7. The housing of claim 1 , wherein one of the exterior walls forms a ceiling of the housing and another of the exterior walls forms a floor of the housing, wherein said one exterior wall forming the ceiling includes a first input/output port and said another exterior wall forming the floor includes a second input/output port.

8. The housing of claim 1 , wherein the first input/output port is offset from the second input/output port in a top plan view of the housing.

9. An aftertreatment system for an engine, comprising:
at least one aftertreatment component; and
a housing configured to house the at least one aftertreatment component, the housing having:
a plurality of walls defining an interior cavity configured to enclose the at least one aftertreatment component, a subset of the plurality of walls each having at least one corrugated panel, and
a frame formed by a plurality of beams, the frame supporting the plurality of walls,
wherein the at least one corrugated panel includes alternating grooves and ridges, and
wherein each alternating ridge of the at least one corrugated panel includes a raised wall, the raised wall including one or more extension portions, each said extension portion overlapping and contacting a corresponding one of the plurality of beams, and
wherein at least one of the one or more extension portions includes a first bent edge that wraps around and engages a first beam of the plurality of beams of the frame and a second bent edge opposite the first bent edge that wraps around and engages a second beam of the plurality of beams of the frame.

10. The aftertreatment system of claim 9 , wherein the at least one corrugated panel of each wall of the subset of walls is integrally formed with the wall.

11. The aftertreatment system of claim 9 , wherein the at least one corrugated panel of each wall of the subset of walls runs along one of a length or a breadth of the wall.

12. The aftertreatment system of claim 9 , wherein each alternating groove of the at least one corrugated panel is U-shaped including a base wall and a pair of side walls, and wherein for each alternating ridge of the at least one corrugated panel the raised wall is spaced apart from the base wall.

13. The aftertreatment system of claim 12 , wherein the base wall is parallel to the raised wall and the pair of side walls is at right angles to each of the base wall and the raised wall.

14. An engine system comprising:
an aftertreatment system configured to receive exhaust gas from an engine, the aftertreatment system including:
at least one aftertreatment component; and
a housing configured to house the at least one aftertreatment component, the housing having:
a plurality of single-layer walls defining an interior cavity configured to enclose the at least one aftertreatment component, at least one of the walls having at least one corrugated panel, and
a frame formed by a plurality of beams, the frame supporting the plurality of walls,
wherein the at least one corrugated panel includes alternating grooves and ridges,
wherein each alternating ridge of the at least one corrugated panel includes a raised wall, the raised wall including extension portions that extend in opposite directions from each other, each said extension portion overlapping and contacting a corresponding one of the plurality of beams, and

wherein at least one of the extension portions includes a bent edge that wraps around and engages one of the beams of the plurality of beams of the frame.

15. The engine system of claim 14 , wherein each alternating groove of the at least one corrugated panel is U-shaped including a base wall and a pair of side walls, the pair of side walls being at right angles to the base wall, and wherein for each alternating ridge of the at least one corrugated panel the raised wall is parallel to the base wall.
