hey doodles.
had this idea boncing around for nearing a year now, figured get some outside input on it.
its a bit of a "why would you do that" sort of thing, which im aware of.
my guess is it will probably only work a smidge, it would be interesting to know how much or how little it works
so basically, a peltier device is a small plate that runs a 12v current through. one side of the plate generates heat the other side generates cold, and you direct that heat or cold to what you want to cool or heat.
to my unsterstanding its less efficient at cooling but still does a good job on small things, like water coolers, car fridges and cooling CPU's.
so here is the basic run down of a potential way to use it as a air cooler (if its even effective)
basically, attach pelteir to a section of fan box with cold sink sticking into fan box to transfer cool temps to passing air. then insulate the other side and run a water plate to pump the heat away from the hot side to a small radiator on the front of the car.
Considerations i thought of when thinking it up (incase it interested anyone to know the thought process)
1. keeping cold side as short as possible so no cold loss in getting the cold to the fan box. hot side can be as long as it wants as more surface area to dissipate heat, and the more water in the lines the more thermal capacity the hot side has.
2. the faster you can cool the hot temps the more effective the cold side will be as it pulls the cool from there so if the hot side is kept cool there is more cold "resource" to use.
3. using a cold sink in the fan box will make for a faster cooling of the cold sink but will have less cold thermal capacity. for more thermal capacity but slower cool down you could use a radiator like the hot side which will have fluid which has a much larger thermal capacity.
thoughts, suggestions, inputs, tell me im crazy?
