Abstract: A cooler housing capable of encasing, protecting, and supporting cooler components, particularly components necessary for use as a portable evaporative cooler. Though the housing described herein may be used in cooling devices ranging from simple conventional fans to complex heat exchanger devices, the preferred embodiment of this invention is preferably used in conjunction with a portable evaporative cooler employing this housing and further comprising a motor that drives a pump connected to a sump tank.

Abstract: A portable evaporative cooling unit (10) is disclosed. A housing (12) has a front opening (46) and a rear opening (20). Air-permeable water absorption media (22) are disposed across the rear opening (20) of the housing (12). An electric motor driven fan (42) having fan blades (44) is disposed in the front opening (46) of the housing (12) for drawing air through the water absorption media (22). A supply conduit (94) connects a water pump (52) to an elongated horizontal spray bar (64) disposed above the water absorption media (22). The spray bar (64) extends substantially the width of the water absorption media (22) and has a plurality of spaced holes (72) in its upper surface for distributing water. A foam sleeve (68) is disposed around the entire length of the spray bar (64). The foam sleeve (68) absorbs water expelled from the plurality of holes (72) and distributes the water onto the water absorption media (22).
