Abstract
The invention relates to an evaporative cooling device including a stand-alone housing that is not connected to any structure. The housing has at least one vertical side with an opening and an evaporative pad is placed inside the opening. An electric centrifugal blower is placed inside the housing to draw air through the evaporative pad 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. The spout may be adapted to oscillate back and forth to deliver air evenly across a room.
