ABSTRACT:
A highly efficient, multi-stage evaporative air cooler for either residential or commercial applications comprises an internal air pathway traversing an evaporative pad more than once. The cooler comprises an upright free-standing cabinet having an air inlet and a frontal surface through which cooled air is discharged. A rigid cage disposed internally within the cabinet comprises a rigid front plate and a separator plate which divides the cage into separate compartments. The periphery of the cage is completed by a pad support mesh, comprising a grid-like wire wall extending around and between the front plate edges and about the separator plate. An absorbent evaporative pad surrounding the cage adjoins and is supported by the pad support mesh. An internal annular boundary volume defined between the cage and the interior walls of the cabinet establishes fluid flow communication between the separate cage compartments. A fan and a blower motor assembly are secured to the separator plate within the cage. The air path traverses the evaporative media pad twice. Air sucked through the top of the cabinet enters the first cage compartment and cools the motor therewith. Air is drawn out of this upper cage compartment through the evaporative media and the cage walls into the boundary annulus. Air is drawn through the evaporative pad into the second cage compartment, and it is forced outwardly through the fan.
