HAHAHA LOL Interesting concept

[nkcd]

So here I am, trying to open my Countertop Water Cooler to see what kind of pump and stuff that they have so I can use it to implement into my chilled water project and guess what do I find?

TEC. Yes, they use TEC to cool the damn water bottle. So here I am, disassemble it, it has everything I needed for a TEC setup.

A TEC Plate
A transformer - Toroidal Transformer, P/N: BU2100C1212, 100VA rating?
A circuit to power the TEC :santa:
2 pin out for Fan :)
2 Pin ou for LED :cool:
2 pin out for Temperature sensor??? (not sure since they have two wires running down to the bottom of the reservoir.?

And they cool the damn thing by big old HS and FAN. :bang head

Anyhow, I got couple questions for TEC guys out there.

How can I determine what wattage they use for the TEC: 80, 176, 226?? and what kind of transformer they use and how many amps the ciruit pack is producing? The spec on the cooler says that it's good for 46-59F for the cold water?

Also, the cooler stopped working a while ago - I wonder what might cause it? inadequate cooling for the hot side causing the TEC plate to burn out???

If I'm able to find out how good the transformer and the circuit is good for, All I need is prolly a new TEC plate and a WC setup :shrug: and not have to think about chilled-liquid cooling

Unless it chills water down in a couple of seconds, there's a very very good chance that that tec isnt more than 40-50 watts, being that it's only cooled by a HSF.

You'd be better off just going with a 226 watt pelt or a 320 watt pelt like ls7's setup on the front page.

I think so too, it did take a while to chill the water, so I'm thinking this is <100w TEC, and the transformer is likely to produce <14 amp for the 12V line. Oh well.

The reason I got overly excited is because I originally didn't want to go TEC since it's more expensive than a conventional AC chilled-liquid setup. Guess I'll have to go back to my original plan then, chilled liquid.
