Introduction: 12 Volt DC Cooler
These portable 12 volt DC coolers are really cool and works good. You can uses theses in a small room, a tent when camping or even in your car. I use a 12 volt battery to power the DC fans. I used four small fans that I wired together. I cut a square out for the fans and cut a circle out for the cold air to come out. You fill the cooler with bottles of ice water and the fan blows on the ice water cooling the air to come out the top vent.
Step 1: Tools and Supplies
banana plug connectors
Step 2: Cutting
I first made a prototype out of a styrofoam cooler. I simply traced the the out venting on the top of the cooler, then used a jig saw to cut out the hole the right size. Then i did the same thing with the DC fan. I traced it on the front of the cooler then used a drill to cut out a small circle so I could fit the jig saw in to cut.
Step 3: Building
Building the portable DC powered air cooler is pretty straight foward. Once you have your holes cut i simply put the top venting in the hole. Mines fit in really nice i did not glue or screw it down because I have it so that i can take off the top vent and put it in the cooler for transporting. I put the fan in the front facing inward to the cooler blowing on the ice bottles. I had to solder all the wires from the fans together then I added a switch also. Then I connected the positvie and negative wires to banana plugs for easy use.
We have a be nice policy.
