Abstract
A shroud, including a shield placed on either side of an evaporation pad, increases the length of travel air transit time within the pad. Pressurized water, emitted in jets from a plurality of orifices spaced along a manifold, is directed against a diffuser for dissipation and dissemination to the upper edge of the pad. The pad is wetted intermittently as the result of a timer controlling distribution of the water. An auxiliary reservoir, in combination with relocatable pump, inlet valve and pad frames, provide for alternate downdraft as side draft operation. An elongate, arcuate baffle downstream of the evaporative pad alters the direction of the air stream to flow in a substantially opposite direction.
Claims4
In an evaporative cooler including
- a housing having an upright surface with an opening therein,
- an air pervious, liquid absorbing evaporative pad spanning said opening and having a discharge surface,
- means for supplying liquid to said pad, and
- blower with said housing means for drawing a stream of air through said pad,
- said stream of air exiting said pad in a direction generally normal to said discharge surface and having droplets of said liquid entrained therein,
- improvements therein for settling said droplets from said air stream, said improvements comprising:
- baffle means downstream of said discharge surface for receiving said air stream thereagainst, said baffle means being generally elongate and having a longitudinal edge substantially parallel to the discharge surface of said pad and being generally arcuate in cross-section such that the direction of said air stream is altered to flow in a substantially opposite direction.
