  • Patent number: 7232076
    Abstract: A water spreader arrangement for use in an evaporative air cooler in which the spreader includes an inlet leading to generally vertical projections disposed over several levels. The projections are adapted to divide a single stream of water entering the inlet into many outlet streams, all of which have a predetermined ratio of flow rates. The outlet streams can be fed to an evaporative pad of an evaporative cooler. In a preferred form, the outlet streams have substantially the same flow rate. Preferably, a cooler incorporating this water spreader arrangement would include several spreaders around the upper periphery of the evaporative pads.
    Type: Grant

  • Patent number: 6669119
    Abstract: A water spreader arrangement for use in an evaporative air cooler in which the spreader includes an inlet (28) leading to generally vertical projections (38) disposed over several levels. The projections (34, 37, 38) are adapted to divide a single steam of water entering the inlet (28) into many outlet streams, all of which have a predetermined ratio of flow rates. The outlet streams can be fed to an evaporative pad of an evaporative cooler. In a preferred form, the outlet streams have substantially the same flow rate. Preferably, a cooler incorporating this water spreader arrangement would include several spreaders around the upper periphery of tho evaporative pads.

  • Patent number: 6450485
    Abstract: A water entry system for entry of water to a water distribution system for an evaporative cooler includes a conduit for delivering water to at least one of the uppermost corners of the lid of the evaporative cooler. The corner having the conduit includes a capped water entry point that causes the water to form a substantially uniform curtain of water which is in turn feeds the water into a plurality of channels and thus to evaporative pads of the evaporative cooler.
