Efficient Water Cooling and Proofing Solutions for Any Project - PF"

[tomizzo]

Hello PF,

I'm working on a little project where I would like to chill and regulate the temperature of water. I'm looking for a fairly cheap way to keep approximately 2 liters of water somewhat cold. I've been looking at some thermoelectric coolers and stumbled across https://www.amazon.com/dp/B002UQQ3Q2/?tag=pfamazon01-20 on amazon.

Three questions:

What would be a good way about water proofing these?

It's possible that there are better alternatives to cooling water. Can you think of one?

How much cooling do you need? Inlet and outlet temperature and flow rate of the water and wattage of the load. And how do you plan to cool the TEC?

I'm not sure the point of waterproofing though; it shouldn't be getting wet.
