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.

An evaporative cooling device including a combination of insulative surfaces and evaporative surfaces that may hold and cool contents with walls that are made of semipermeable materials. The evaporative surfaces store and facilitate the evaporation of a liquid to cool the interior of the evaporative cooling device while the insulative surfaces limit heat transfer in or out of the evaporative cooling device from air, sunlight or the ground. The evaporative cooling device is further capable of holding a variety of products at a temperature below ambient environmental temperature, assuming less than 100% humidity. Moreover, the evaporative cooling device may be designed to be lightweight and collapsible for easy transport and storage.

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.

A portable cooling unit for cooling and insulating a vessel. The unit has a thermally insulating envelope that includes a breathable reflective layer, a breathable waterproof layer and an opening for accessing the vessel. A cooling envelope that is arranged to cool and house the thermally insulating envelope and the vessel. The cooling envelope has two water-permeable layers and an opening for accessing the vessel. The unit further has a housing envelope that is arranged to house the vessel, the cooling envelope and the thermally insulating envelope. The housing envelope includes an opening for accessing the vessel and a breathable water-permeable layer that allows moisture to cross the envelope. The two water-permeable layers of the cooling layer are arranged to bound an enclosure containing an absorbent and moisture-wicking material that is arranged to cool the vessel via evaporation of water.

A cooling garment cooling device includes: a water delivery hose with a cooling water supply portion and cooling water branch portion; a pump supplying cooling water from the cooling water supply portion toward the cooling water branch portion; and plural branched water hoses having a first end-side water supply portion and second end-side water supply portion coupled to the cooling water branch portion. A portion of the branched water hoses between the first end-side water supply portion and second end-side water supply portion serves as a water outlet portion. Each branched water hose diameter is smaller than the water delivery hose diameter. The outer peripheral portion of the water outlet portion of each branched water hose orthogonal to the longitudinal direction of the branched water hose has plural water passage holes with opening areas smaller than those of the first end-side water supply portion and second end-side water supply portion.
