Abstract: A frame for an evaporative cooler includes a bottom channel including a bottom panel and two bottom-side panels, a top channel including a top panel and two top-side panels, and a pair of side channels disposed between, and engaged with, each of the bottom channel and the top channel. The side channels may include a vertical side panel, a flanged bottom, a flanged top, and a pair of flanged sides, where the flanged bottom is engaged with the bottom panel, the flanged top is engaged with the top panel, and each of the pair of flanged sides is engaged with a bottom-side panel of the bottom channel and a top-side panel of the top channel.

Abstract: A support system for rigid media of an evaporative cooler includes a water distribution pipe, a bottom support including at least one sidewall extending from a bottom surface of the bottom support, and a rigid media block having a bottom end at least partially supported by the bottom surface of the bottom support, the rigid media block including a slot formed across a top surface thereof and having the water distribution pipe running through the slot, the slot having a depth selected such that a gap is formed below the water distribution pipe when the water distribution pipe is disposed within the slot and the bottom end of the rigid media block is engaged with the bottom surface of the bottom support.

Abstract: This invention provides simple, low-cost designs for rooftop support of pipes on low-slope commercial and industrial roofs. The designs use cut pieces of extruded plastic shapes with holes or slots transverse to the extrusion direction. The supports are designed to be lightly adhered to the roof, and to allow pipe movement for expansion and contraction.
