Abstract

An emissions cleaning module electronics support unit includes a base member which defines at least one seating location for an electronics module; and a roof member includes a first end joined to the base member and a second end, distal the base member, coupled to a brace or one or more conduits of the emissions cleaning module. The roof member may be shaped to extend up and over the base member so as to create an open-mouthed cavity. The base member may include one or more apertures creating tortuous thermal paths between the attachment member and electronics module seating location.

First claim

The invention claimed is:

1. An emissions cleaning module comprising:
a first support;
a second support;
a brace extending between the first support and the second support; and
one or more fluid-treatment modules located in one or more conduits extending between the first support and the second support, and an electronics support unit comprising:
a base member which defines at least one seating location for an electronics module; and
a roof member;
wherein, the roof member comprises a first end adjacent the base member and a second end, distal the base member, which is coupled to the brace and/or the one or more conduits;
the roof member being shaped to extend up and over the base member such that a cavity is defined between the base member and the roof member and configured for receiving an electronics module to be seated at the at least one seating location, wherein the brace includes a cut-out in which the electronics support unit is at least partially located.

2. An emissions cleaning module as claimed in claim 1 wherein the roof member is a heat shield for shielding an electronics module seated at the at least one seating location from heat emanating from the one or more fluid-treatment modules.

3. An emissions cleaning module as claimed in claim 1 wherein an air flow gap is provided between the roof member and the one or more fluid-treatment modules.

4. An emissions cleaning module as claimed in claim 1 wherein the electronics support unit depends from the brace and/or the one or more conduits.

5. An emissions cleaning module as claimed in claim 1 wherein the brace is elongate and has an L-shaped cross-section defining first and second flanges joined along a common edge, and arranged at an angle to each other, the cut-out being formed in the first and second flanges so as to be intersected by the common edge.

6. An emissions cleaning module as claimed in claim 1 wherein the base member and the roof member are integrally formed.

7. An emissions cleaning module as claimed in claim 1 wherein the base member comprises a front edge, a rear edge and side edges joining the front edge and the rear edge; wherein the roof member extends upwardly from the rear edge of the base member; wherein the cavity is accessible from the front edge or the side edges of the base member.

8. An emissions cleaning module as claimed in claim 1 wherein the second end of the roof member comprises one or more attachment points for coupling the roof member to the brace and/or the one or more conduits.

9. An emissions cleaning module as claimed in claim 1 wherein the base member comprises a substantially flat plate.

10. An emissions cleaning module as claimed in claim 1 wherein the base member comprises one or more upstanding tabs to define the at least one seating location for an electronics module.

11. An emissions cleaning module as claimed in claim 1 wherein the base member comprises one or more apertures.

12. An emissions cleaning module as claimed in claim 11 wherein a remainder of the base member defines one or more thermal paths between the roof member and the at least one seating location for an electronics module.

13. An emissions cleaning module as claimed in claim 1 further comprising an electronics module coupled to the base member at the at least one seating location.

14. An electronics support unit comprising:
a base member which defines at least one seating location for an electronics module; and
a roof member;
wherein, the roof member comprises a first end adjacent the base member and a free-standing second end distal the base member;
the roof member being shaped to extend up and over the base member such that a cavity is defined between the base member and the roof member and configured for receiving an electronics module to be seated at the at least one seating location, wherein the second end of the roof member includes one or more attachment points for coupling the roof member to a brace of the type including a cut-out in which the electronics support unit can be at least partially located.

15. An electronics support unit as claimed in claim 14 wherein the base member and the roof member are integrally formed.

16. An electronics support unit as claimed in claim 15 wherein the base member and the roof member are formed from a folded sheet.

17. An electronics support unit as claimed in claim 14 wherein the base member comprises a front edge, a rear edge and side edges joining the front edge and the rear edge; wherein the roof member extends upwardly from the rear edge of the base member; wherein the open-mouthed cavity is accessible from the front edge or the side edges of the base member.

18. An electronics support unit comprising:
a base member which defines at least one seating location for an electronics module; and
an attachment member;
wherein, the attachment member comprises a first end adjacent the base member and a second end distal the base member;
wherein the base member comprises one or more apertures creating one or more tortuous thermal paths between the attachment member and the at least one seating location for an electronics module, wherein the second end of the attachment member includes one or more attachment point for coupling the attachment member to a brace of the type including a cut-out in which the electronics support unit can be at least partially located.
