evaporation (swamp) cooler

thingiverse

This system utilizes evaporation to cool the air effectively, requiring four feet, two saddles, one right shelf, and one left shelf for the fan to function properly. Four tees are necessary to hold the water tray in place, along with an overflow drain to prevent water from spilling over. I employed 1" PVC pipe, 34mm OD, and a two-inch pipe, 60mm OD, to construct the spreader bar. Two pipe caps are required for the spreader bar, a tray for the water can be sourced from a garden center, and an aquarium pump is also necessary. To ensure efficient water flow, drill 3mm holes at the bottom of the spreader bar for the water to drip through, and install the overflow about halfway up on the bar. A piece of old garden hose should be connected from the pump into the bar for optimal performance. Using a blower or blowing air through the material, such as curtain shear cloth, is not necessary due to its limited porosity, but it would still work effectively if the right material were used. This system consumes approximately 2 liters of water per day and cools efficiently. When selecting pipe, ensure it fits through the holes before printing too far to avoid wasting time and resources.
