Manifold for controlling airflow within an explosion-proof enclosure
First Claim
1. A manifold within an explosion-proof enclosure, the manifold comprising:
- a housing having a first end and a second end, wherein the second end abuts against an inner surface of an outer wall of the explosion-proof enclosure;
an inlet duct coupled to an air moving device and disposed within the first end of the housing, wherein the inlet duct is configured to receive exhaust air from the air moving device;
an outlet duct comprising a first perimeter and at least one channel, wherein the outlet duct is disposed within the second end of the housing, wherein the outlet duct is configured to send the exhaust air outside the explosion-proof enclosure, wherein the first perimeter of the outlet duct is coupled to a first portion of the inner surface of the outer wall of the explosion-proof enclosure, wherein the first portion of the inner surface comprises at least one aperture that traverses the outer wall;
a body comprising a cavity and disposed within the housing between the first end and the second end of the housing, wherein the body couples the inlet duct to the at least one channel, and wherein the exhaust air flows from the inlet duct through the cavity to the outlet duct; and
a bracket that abuts against and overlaps an outer surface of the outlet duct adjacent to the first perimeter of the outlet duct to secure the outlet duct to the explosion-proof enclosure, wherein the bracket is coupled to a second portion of the inner surface of the outer wall of the explosion-proof enclosure, wherein the second portion encompasses the first portion,wherein the explosion-proof enclosure, when the bracket abuts against and overlaps the outer surface of the outlet duct, and when the bracket abuts against and is coupled to the inner surface of the outer wall of the explosion-proof enclosure, meets applicable industry standards for the explosion-proof enclosure.

Abstract
A manifold within an explosion-proof enclosure is described herein. The manifold can include an inlet duct coupled to an air moving device, where the inlet duct can receive exhaust air from the air moving device. The manifold can further include an outlet duct that includes a perimeter and at least one channel, where the outlet duct can send the exhaust air outside the explosion-proof enclosure, where the perimeter of the outlet duct is coupled to a first portion of an inner surface of an outer wall of the explosion-proof enclosure, and where the first portion of the inner surface includes at least one aperture that traverses the outer wall. The manifold can also include a body that includes a cavity, where the body couples the inlet duct to the at least one channel, and where the exhaust air flows from the inlet duct through the cavity to the outlet duct.

16. A method for controlling flow of exhaust air through an explosion-proof enclosure using a manifold, the method comprising:
-
receiving, using an inlet duct disposed in a first end of a housing of the manifold, the exhaust air, wherein the manifold is located inside the explosion-proof enclosure, wherein the exhaust air is generated by an air moving device; channeling, through a body disposed in a portion of the housing of the manifold adjacent to the first end and using a positive pressure created by a seal formed between a second end of the housing of the manifold and a portion of an inner surface of an outer wall of the explosion-proof enclosure, the exhaust air toward the outer wall of the explosion-proof enclosure; and sending, through an outlet duct disposed in the second end of the housing of the manifold, the exhaust air through at least one aperture in the outer wall of the explosion-proof enclosure, wherein the at least one aperture in the outer wall of the explosion-proof enclosure is located within the portion of the inner surface of the outer wall, wherein a second end of the housing of the manifold abuts against the inner surface of the outer wall of the explosion-proof enclosure, wherein the first perimeter of the outlet duct is encompassed by a bracket of the manifold, wherein the bracket abuts against and overlaps an outer surface of the outlet duct adjacent to the first perimeter of the outlet duct to secure the outlet duct to the explosion-proof enclosure, wherein the bracket is coupled to the inner surface of the outer wall of the explosion-proof enclosure, wherein the explosion-proof enclosure, when the bracket of the manifold abuts against and overlaps the outer surface of the outlet duct, and when the bracket is coupled to the inner surface of the outer wall of the explosion-proof enclosure, meets applicable industry standards for an explosion-proof enclosure. - View Dependent Claims (17, 18, 19)
