Surface dryers producing uniform exit velocity profiles, and associated systems and methods
Surface dryers having uniform exit velocity profiles, and associated systems and methods are disclosed. Surface dryers in accordance with certain embodiments include a housing, a gas driver positioned in the housing, an inlet aperture formed in the housing and positioned upstream of the gas driver, and a nozzle carried by the housing and positioned downstream of the gas driver. The nozzle can have an indentation forming a convergent portion positioned to accelerate the flow of air and a divergent portion positioned to decelerate the flow of air.
1. A stackable air mover for producing uniform air velocity profiles, comprising:
a housing at least partially enclosing an interior chamber, wherein the housing includes an upper housing portion, a first sidewall portion, a second sidewall portion, and a lower housing portion, and wherein the upper housing portion includes a flat portion and an inclined portion, and wherein the flat portion is generally parallel to the lower housing portion, and wherein the first sidewall portion is asymmetric relative to the second sidewall portion;
an inlet having an inlet aperture formed in the flat portion;
an outlet having an outlet aperture, wherein the outlet aperture is enclosed by the inclined portion, the first and second sidewall portions, and the lower housing portion, and wherein the first and second sidewall portions have unequal heights at the outlet aperture; and
an impeller positioned within the interior chamber to drive a flow of air, wherein the flow of air flows through the inlet aperture in a first direction, and wherein the flow of air flows through the outlet aperture along a second direction different than the first direction.
2. The stackable air mover of claim 1 , wherein the first direction is generally perpendicular to the second direction.
3. The stackable air mover of claim 1 , further comprising a support device having an engaging surface positioned to contact a target surface.
4. The stackable air mover of claim 1 , further comprising a support device positioned to locate the inlet at a predetermined height relative to a target surface.
5. The stackable air mover of claim 1 , wherein the inlet aperture has a concave contoured shape.
6. The stackable air mover of claim 1 , wherein the outlet aperture has a pinched region, with the upper and lower housing portions converging toward each other in a direction from the first sidewall portion toward the second sidewall portion.
7. The stackable air mover of claim 1 , wherein the stable air mover is stackable in the first direction.
