Abstract:
1. An evaporative stand-alone cooling device comprising: (a) a housing having a multiple of open vertical sides including wettable evaporative pads placed in each of said openings of said open vertical sides; (b) means for delivering water to each top of said evaporative pads to flow downwardly through said pads by gravity; (c) a sump located at the bottom of said housing to collect excess water therein from said evaporative pads; (d) a pump placed in said sump being the said means for delivering water to the top of each of the pads and a float is located in said sump to detect a minimum level of water in said sump to stop said pump; (e) said housing further including a centrifugal blower driven by a first 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 pads; (g) means for driving an oscillating and rotatable spout being placed over said opening to direct air in multiple directions; wherein said spout has a circular bottom ring and said top cover has a circular recess receiving said ring including means for clamping said spout in any adjustable rotational position.
