Abstract

Apparatus are provided for a shield and flange support for a duct. The shield and flange support includes a first side and a second side coupled to the first side to extend toward the duct. The first side and the second side cooperate to define a cavity, and the cavity includes at least one of a first insulating fluid and a first insulating solid.

First claim

What is claimed is:

1. A duct system, comprising:
a duct having a plenum including a first end and a second end, with a plurality of sides between the first end and the second end, the first end including a flange that extends outwardly away from the first end and the plenum extends along a longitudinal axis;
a shield and flange support for the duct including a body having a first side, a second side, a third side, a fourth side and defining a cavity;
the first side is coupled to the flange about the first end;
the second side is coupled to the first side to extend toward the plurality of sides of the plenum, the second side interconnects the first side and the third side;
the third side is coupled to the plurality of sides of the plenum about the first end and is coupled to the second side;
the fourth side interconnects the third side and the first side, and the fourth side is substantially transverse to the longitudinal axis; and
the first side, the second side, the third side and the fourth side cooperate to enclose the cavity, the cavity including at least one of a first insulating fluid and a first insulating solid and the fourth side is spaced apart from the flange and the plurality of sides of the plenum to define a gap between the body and the plenum for receipt of at least one of a second insulating fluid and a second insulating solid.

2. The duct system of claim 1 , wherein the body is discrete from the flange.

3. The duct system of claim 2 , wherein the body includes a plurality of sections that are coupled together to extend about a perimeter of the first end of the plenum.

4. The duct system of claim 1 , wherein the cavity is filled with a honeycomb material.

5. The duct system of claim 1 , wherein the shield and flange support comprises a first body portion and a second body portion, with the first body portion including the first side and the second body portion including the second side.

6. The duct system of claim 5 , wherein the first body portion is removably coupled to the second body portion.

7. The duct system of claim 1 , wherein the duct is an inlet duct.

8. The duct system of claim 1 , wherein the second side includes an overhang portion, and the overhang portion extends beyond an end of the flange.

9. The duct system of claim 1 , wherein at least one of the first side, the second side, the third side and the fourth side include a coating.

10. A duct system, comprising:
a duct having a plenum including a first end and a second end, with a plurality of sides between the first end and the second end, the first end including a flange that extends outwardly away from the first end about a perimeter of the first end and the plenum extends along a longitudinal axis;
a shield and flange support for the duct including a body having a plurality of sides that cooperate to enclose a cavity, with a first one of the plurality of sides coupled to the flange, the first one of the plurality of sides is substantially perpendicular to the longitudinal axis, a second one of the plurality of sides coupled to the plurality of sides of the plenum about the perimeter, the second one of the plurality of sides is substantially parallel to the longitudinal axis, a third one of the plurality of sides of the body is spaced apart from the flange and the plurality of sides of the plenum to define a gap between the body and the plenum, the third one of the plurality of sides interconnects the first one of the plurality of sides and the second one of the plurality of sides and extends along an axis transverse to the longitudinal axis, a fourth one of the plurality of sides interconnects the first one of the plurality of sides and the second one of the plurality of sides, the fourth one of the plurality of sides substantially opposite the third one of the plurality of sides, and the body is coupled to the flange and the duct such that the body extends along a second longitudinal axis substantially transverse to the longitudinal axis of the plenum.

11. The duct system of claim 10 , wherein the body includes a plurality of sections, which are coupled together to define an area of overlap and to extend about the perimeter of the first end of the plenum.

12. The duct system of claim 10 , wherein at least one of the plurality of sides includes a coating.

13. The duct system of claim 10 , wherein at least one of a first insulating fluid and a first insulating solid are received in the cavity.

14. The duct system of claim 13 , wherein the gap receives at least one of a second insulating fluid and a second insulating solid.

15. The duct system of claim 10 , wherein one of the first one of the plurality of sides and the second one of the plurality of sides is removably coupled to the body.

16. A duct system, comprising:
a duct having a plenum including a first end and a second end, with a plurality of sides between the first end and the second end, the first end including a flange that extends outwardly away from the first end about a perimeter of the first end; and
a shield and flange support for the duct, the shield and flange support including:
a body that includes a first side, a second side, a third side and a fourth side, the first side coupled to the flange about the perimeter of the first end;
the second side coupled to the first side, and the second side interconnects the first side and the third side;
the third side coupled to the second side and to the plurality of sides of the plenum about the perimeter of the plenum; and
the fourth side interconnects the first side and the third side, the first side, the second side, the third side and the fourth side cooperating to enclose a cavity defined within the body, with at least one of a first insulating fluid and a first insulating solid received in the cavity, and the fourth side is spaced apart from the flange and the plurality of sides of the plenum to define a gap about the perimeter of the first end between the body and the plenum for receipt of at least one of a second insulating fluid and a second insulating solid.

17. The duct system of claim 16 , wherein the first side, the second side, the third side and the fourth side form a section, and the shield and flange support includes a plurality of sections that are coupled together to extend about the perimeter of the first end of the plenum.

18. The duct system of claim 16 , wherein at least one of the first side, the second side, the third side and the fourth side includes a coating.
