You can also circulate chilled water (a correctly dosed antifreeze allows you to have a cooling liquid that remains liquid even at -20 ° C) by having the production of cold (by pelletier modules ...) away from the place you're looking to cool down.
In short, the idea being to evacuate calories, whether the liquid is upstream, downstream, or in the middle of the circuit providing this function does not change much.

So Forhorse, if I summarize I need a peltier for the production of cold and another peltier to cool the ice water and the antifreeze which will cool the hot face of the first peltier?
But how do you check that the heat produced by the two peltiers does not take over the production of cold?
If someone is very familiar with energy efficiency calculations on peltier effects (real specialist) please contact me Thaddee.caron@gmail.com, advice and calculations will of course be remunerated!
THAD wrote:So it's impossible in fact? are peltier modules for cold production therefore useless because the efficiency is ridiculous? There are no peltier modules optimized only for cold?

If you are really familiar with peltier effect modules or if you know qualified people, you can send me an email to join the adventure.
And I also wonder about water-cooling, according to you for a power device similar to a small fridge. A water-cooling device instead of peltier modules would it not be more advantageous in terms of place-power ratio as I recall I am very very limited in space,
To give you an idea my object is similar in size to a macbook and should provide similar cooling power to a small fridge
