does any one have any ideas on how these could be used??

AKA peltier cooler. They're a ***** to power (especially in a car) and a ***** to cool.
i dont understand how it works

I'm not sure of the internals, but one side gets really hot and the other gets really cold.
it said on the page they where intended for 12v use. what would you need to power them??
Um...is this a trick question? 12 volts...Originally Posted by odleon
I would not recommend you use peltiers in carputer applications. First of all, it requires energy to move energy. The power draw on these things are killer: the peltier I've used in overclocking a desktop is a 6A draw at 12V. Secondly, all they do is maintain a temperature differential. So, in order to keep the cool side cool, you have to keep the hot side cooled (liquid cooling, etc). Fans attempt to bring temperatures down to ambient temps, peltiers actually pull heat out to create below-ambient temps. Since I don't see the need to create sub-zero temps in a car environment, I advice against peltiers.

from the site you linked egeekial,
Methods that have been used to cool overclocked components include: forced convection (a fan blowing onto a surface); liquid cooling (liquid carries waste heat to a radiator, similar to how automobile engines are cooled); liquid nitrogen (perhaps the most dangerous method); dry ice; phase change cooling (as used in refrigerators); and submersion (placing the entire computer in an inert fluid). Liquid nitrogen is a temporary cooling measure in most cases, since a sufficient supply of power to maintain the LN2 coolant at liquid state is uneconomical. Because of this, liquid nitrogen (or dry ice, for that matter) is used as an extreme measure to set a record in a one-off experiment rather than to cool a system for a normal period of use. One reason is the cost of these extreme cooling methods, or usually because the hardware exposed to such cooling is ironically destroyed in the process. Of the aforementioned methods, air cooling, liquid cooling, and phase cooling are the most popular, due to their efficiency, availability, and affordability.
interesting idea for cooling in the car, I recall seeing several exhibits of computers submerged in liquid.....if someone did this in the car, that would be very cool

was refering to his comment. if thay are a ***** to power, how do you do it??
