High air temperatures can be brutal in a car without air conditioning. Dealing with a hot car does not have to be such a problem though. With dry ice, a fan and a little know how, you can rig a cost effective solution that will cool the car down to where you can drive it in some semblance of comfort. Then you will be better able to concentrate on driving. Because air blowing over the dry ice will provide some of the comfort that normal air conditioning provides.
Here’s the things you’ll need:
rectangular ice bin
12-volt clip-on fan with cigarette lighter plug
pair of thick leather gloves
First, set the rectangular ice bin flat on the floorboard of the passenger’s side front seat.
Now place the dry ice into the rectangular ice bin. Use the thick leather gloves to do this in order to keep your hands safe from the freezing that dry ice can cause.
Next, clip the 12-volt clip-on fan onto the side of the rectangular ice bin.
For step four, plug the 12-volt fan’s cigarette lighter plug into the cigarette lighter of the car.
Finally, turn on the fan in order to blow air over the dry ice. After about 15 minutes the temperature inside the car will begin to cool down.
Please pay attention to this warning. Keep a small crack in both the driver’s side and passenger’s side windows in order to vent the carbon dioxide gas out of the car that the dry ice will give off. Failure to do this can cause you to suffocate from breathing in too much carbon dioxide.
