Claim:
1. A shroud for an electrical enclosure comprising: a body having a top end, a bottom surface located opposite the top end, a first end, and a second end located opposite the first end, wherein the bottom surface is configured to abut against an outer surface of a wall of an enclosure, and wherein the first end and the second end are disposed between and adjacent to the top end and the bottom surface, wherein the bottom surface forms a first aperture adjacent to the cavity; a cavity under the top end of the body and disposed toward the first end, wherein the cavity is configured to receive air that flows in a first direction through the first aperture toward the top end, wherein the first direction is substantially perpendicular to the wall of the enclosure; at least one non-linear channel disposed at a side of the cavity between the top end and the outer surface of the wall of the enclosure, wherein each of the at least one non-linear channels comprises a bent passage, a third end, and a fourth end, wherein the third end adjoins the cavity, wherein the air flows through the at least one non-linear channel between the cavity and the fourth end in a plurality of second directions, wherein the plurality of second directions is substantially parallel to the wall of the enclosure, wherein each second direction of the plurality of second directions is parallel to the outer surface of the wall of the enclosure where the body abuts against the outer surface of the wall, wherein each second direction of the plurality of second directions is substantially perpendicular to the first direction; and a curved outlet disposed at the second end of the body and comprising a banana-shaped vent that traverses at least two sides of the body, wherein the at least two sides are disposed between the top end and the bottom surface, and wherein the fourth end of each of the at least one non-linear channels adjoins a portion of the banana-shaped vent of the curved outlet, wherein the air flows in at least one second direction of the plurality of second directions, wherein the curved outlet and the at least one non-linear channel prevent substantially all liquids and solids outside the body from entering the cavity, and wherein the air, once inside the cavity, is redirected in at least one second direction of the plurality of second directions toward the side of the cavity and the third end of the at least one non-linear channel.
