Abstract:
An evaporative stand-alone cooling device comprising:(a) a housing having at least one open vertical side including a wettable evaporative pad placed in an opening of said open vertical side; (b) means for delivering water to a top of said evaporative pad to flow downwardly through said pad by gravity; (c) a sump located at the bottom of said housing to collect excess water therein from said evaporative pad; (d) a pump placed in said sump being the said means for delivering water to the top of said pad; (e) said housing further including a centrifugal blower being driven by an electric motor, said blower being mounted in said housing so as to create a positive pressure of vertically flowing air while at the same time creating a negative pressure of laterally flowing air through said evaporative pad; (f) said housing further including a cover at its top having an opening to accommodate said vertically flowing air; (g) an oscillating, rotatable spout being placed over said opening to direct air in multiple directions; and (h) further comprising a second electric motor and a linkage between said second electric motor and said oscillating, rotatable spout, said linkage being adapted to rotate said oscillating rotatable spout alternatively clockwise and counterclockwise, wherein said linkage further comprises a rotating block having a first end and a second end and being connected to said second electric motor at said first end, a socket formed in said second end, a ball loosely engaged in said socket, a rod connected to said ball at a first end of said rod, the second end of said rod being connected to a secondary ball loosely engaged in a secondary socket, said secondary socket being attached to a cross member, said cross member being attached to said oscillating, rotatable spout, wherein said linkage is enclosed within said oscillating, rotatable spout.
