"How to build an Evaporative Cooler for your Pick-up Truck".
Send for your instructions on how to build an evaporative cooler using off the shelf products. Use the air flow from driving down the road as the force passing over wet pads causing the cooling effect of evaporation. With the right mixture of water and air flow, evaporation takes place and the exchange of heat for cool air happens. Using standard 4" PVC pipe and fittings, 1/2" PVC pipe and fittings, standard polyvinal evap pads, a 12 volt DC pump, 12 volt DC battery and a 12 volt DC solar panel you can build an effective independent evaporative cooler for your pick-up truck. Air-conditioners take a lot of energy to work and it also cost a lot of money to fix them. If you are like me the cost to fix or replace the air-conditioner in my truck cost more then the truck is worth. That is why I have come up with a poor man's vehicle evap. Using a standard 12 volt DC boat pump requires more energy (5 amps) and water pressure then is needed, but it is the least expensive, most practical and rugged off the shelf pump available today. That is why I have a separate 12 volt DC power supply to the pump and fan. Pow Wow Sales will have other 12 volt DC pumps available online by the summer of 2014.
