Water drainage assemblies for aftertreatment systems
A water drainage assembly for an aftertreatment system includes: a tube having an inlet structured to be coupled to an outlet conduit of an aftertreatment system; a drain port extending through the tube; a first baffle disposed in the tube, a first baffle first end attached to an inner surface of the tube at a first location, wherein at least a portion of the first baffle is inclined downwards with respect to gravity; and a second baffle disposed in the tube below the first baffle, a second baffle first end being coupled to the inner surface of the tube at a second location that is opposite to and below the first location, wherein at least a portion of the second baffle is inclined upwards with respect to gravity.
1. A water drainage assembly for an aftertreatment system, comprising:
a tube having an inlet structured to be coupled to an outlet conduit of an aftertreatment system;
a drain port extending through the tube;
a first baffle disposed in the tube, the first baffle having a first baffle first end attached to an inner surface of the tube at a first location, wherein at least a portion of the first baffle is inclined downwards with respect to gravity;
a second baffle disposed in the tube directly below the first baffle, the second baffle having a second baffle second end being coupled to the inner surface of the tube at a second location that is opposite to and below the first location, wherein at least a portion of the second baffle is inclined upwards with respect to gravity,
wherein the first baffle is structured to guide water entering the tube towards the second baffle, and the second baffle is structured to guide the water towards the drain port.
2. The water drainage assembly of claim 1 , wherein:
the first baffle comprises a first portion coupled to the tube, and a second portion extending from the first portion, wherein an angle of the second portion of the first baffle with respect to a direction perpendicular to an axis of the tube is greater than an angle of the first portion of the first baffle with respect to a direction perpendicular to the axis of the tube.
3. The water drainage assembly of claim 2 , wherein:
the second baffle comprises a first portion coupled to the tube, and a second portion extending from the first portion, wherein an angle of the second portion of the second baffle with respect to a direction perpendicular to the axis of the tube is greater than an angle of the first portion of the second baffle with respect to a direction perpendicular to the axis of the tube.
4. The water drainage assembly of claim 1 , further comprising a first gap between the first baffle and the inner surface of the tube at a third location that is opposite to the first baffle.
5. The water drainage assembly of claim 4 , further comprising a second gap between the second baffle and the inner surface of the tube at a fourth location that is opposite to the second baffle.
6. A water drainage assembly for an aftertreatment system, comprising:
a tube having an inlet structured to be coupled to an outlet conduit of an aftertreatment system;
a drain port extending through the tube;
a first baffle disposed in the tube, the first baffle having a first baffle first end attached to an inner surface of the tube at a first location, wherein at least a portion of the first baffle is inclined downwards with respect to gravity;
a second baffle disposed in the tube below the first baffle, the second baffle having a second baffle second end being coupled to the inner surface of the tube at a second location that is opposite to and below the first location, wherein at least a portion of the second baffle is inclined upwards with respect to gravity; and
a first gap between the first baffle and the inner surface of the tube at a third location that is opposite to the first baffle,
wherein the first baffle is structured to guide water entering the tube towards the second baffle, and the second baffle is structured to guide the water towards the drain port.
7. The water drainage assembly of claim 6 , further comprising a second gap between the second baffle and the inner surface of the tube at a fourth location that is opposite to the second baffle.
