The invention relates to an evaporative cooling device including a stand-alone housing that is not connected to any structure. The housing is multi-sided and evaporative pads are placed inside the opening of each of the multi-sides. An electric centrifugal blower is placed inside the housing to draw air through all of the eavaporate pads and to discharge the same in a vertical direction through an opening in a top cover. The top cover has a directional spout placed over the opening to direct the air in multi-adjusted directions. The cooling device is intended to be used on wide open playing or sport fields or in open sided warehouses or work stations. A smaller size is intended to be used in semi-confined areas such as verandas, patios, lanais, porches etc. A flexible air duct can be attached to the spout so as to temporarily deliver cooled air to confined spaces such attics in a house.
An evaporative stand-alone cooling device comprising a housing having a multiple of open vertical sides including wettable evaporative pads placed in each of said (openings of said) open vertical sides, means for delivering water to each top of said evaporative pads to flow downwardly through said pads by gravity, a sump located at the bottom of said housing to collect excess water therein from said evaporative pads, a pump placed in said sump being the said means for delivering water to the top of each of said pads and a float located in said sump to detect a minimum level of water in said sump to stop said pump, said housing further includes 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 pads, said housing further includes a cover at its top having an opening to accommodate said vertically flowing air and a rotatable spout being placed over said opening to direct air in multiple directions, wherein each of said evaporative pads is of a sandwich construction consisting of said evaporative pad being placed innermost in each of said open vertical sides, an air filter being placed next to and outwardly of said evaporative pad and a plastic honeycomb grid being placed most outwardly in said open vertical sides to protect the air filter and said evaporative pad from damage and to enhance the aesthetic appearance of the housing.
