Abstract
A duct (100) comprises the molded combination of: an inlet flange (110) surrounding an inlet (102), the inlet having a height and a width; and body (112) extending from the inlet to an outlet (104) and having a body interior that laterally outwardly diverges and upwardly shifts from the inlet toward the outlet.
Claims13
A transport refrigeration system comprising:
- a refrigeration system (30) including:
- a fan (42) for driving air along a flowpath from an inlet (62) to an outlet (64);
- and
- a heat exchanger (38) along the flowpath for cooling the air;
- and
- a duct (100) comprising a twin-sheet thermoformed combination of:
- an inlet flange (110) surrounding an inlet (102), the duct mounted so that the duct inlet (102) receives air from the refrigeration system outlet, the duct inlet having a height and a width;
- and
- body (112) extending from the duct inlet to an outlet (104) and having a body interior that laterally outwardly diverges and upwardly shifts from the duct inlet toward the duct outlet wherein:
- the duct comprises a proximal trunk (130) and a plurality of distal branches (132A-132D);
- a plurality of walls (134A-134C) divide the distal branches, each wall comprising at least one portion protruding upward from a bottom of the body and at least one portion protruding downward from a top of the body and meeting;
- and
- one or more of the walls includes an interrupted portion (186) wherein the interrupted portion of the one or more of the walls protrudes upward from the bottom of the duct to a non-recessed location on the top of the duct.

- and
- a plurality of walls (134A-134C), wherein the plurality of walls divide the plurality of distal branches, each wall comprising at least one first portion protruding upward from a bottom sheet of the body and at least two second portions protruding downward from a top sheet of the body, said at least one first portion and said at least two second portions meeting between said top and bottom sheets;
- and wherein one or more of the walls includes an interrupted portion (186), the interrupted portion formed by deformation of the bottom sheet so that the bottom and top sheets fuse at a location locally coplanar with the top sheet, and said interrupted portion being located between the at least two second portions of a respective wall of said one or more of the walls.
