what would happened if put Peltier into water?
 

I have a custom water cooling system.
I use a very very big water deposit more than 10 liters.
And a very good radiator,but i was wondering about
adding to this big water deposit a Peliter inside.
I mean, imagine a big glass of water with a peltier inside,
what happen?

i don't know too much of pelts, but i'm sure that wouldn't work since there's a hot and a cold side. since both would be in contact with the water....

a water chiller based on pelts is very inefficient if done correctly anyway.

In defense for TEC water coolers:

Commercial aircraft use TEC based water chillers that have 8 smaller TECs running off 36V (series config). I have 2 units in my posession. They work and are not as ineffecient as people make out (of which very few of them have ever done it). Also using a water chiller elminates the need to fill your MB with condensation protection (given reasonable temps) and all that fiddling around with the cold plates, TECs, WB sandwitch.



But, as for sticking a TEC into water...you are leaving yourself open for shorting the PSU.

Well if the peltier wholly submersed in the water didn't short itself out, your water would get hot as the peltier will be emitting as much heat as it's drawing in power from the PSU.

This is a pretty dumb idea if I read it correctly:

You wish to take a TEC and just submerge it in water? Please have a friend there to take pics. Hint: Electricity and water in direct contact aren't a good mix.

If you are asking if you can use peltiers to chill water then the answer is yes but you'll need high W tecs and separate water loops to cool them.

The COP of a TEC is less then 1. Thats very ineffcient. Of course if you get enough power it will work, but that doesn't change the fact that its very ineffcient.

The TEC would act as a heater. Thw water would move in some intersting currents. However the water would eventually heat up and boil since the TEC is still adding energy to the system.
