small refrigeration/evaporation device
(OP)
I need a way to cool water flowing through a 1.5mm ID tygon tube. It needs to be something pocket-sized, and I am having trouble coming up with anything like this. Any suggestions? Thanks.





RE: small refrigeration/evaporation device
To beter give you an answer we need: 1 How much water, 2 how quickly, 3 How big a pocket, and 4 any restriction on what it can have in it (nuclear power devices, batteries, fuels...)

2. needs to cool it at a fast rate, but the deltaT is only 5 degrees F
3. I am hoping to find something 3"x3"x.75"
4. restrictions are that it should be safe to carry on your person. So, nuclear power, acidic, heavy batteries, etc. I cannot use.
Once again, thanks for the help.

peltier cooler?
RE: small refrigeration/evaporation device
means what? nanoseconds? femtoseconds?
TE cooler is one choice. Another would be Freon, CO2, or N2, or Ar.

Thermoelectric coolers - see melcor.com, or better do a google search for that term, or peltier coolers like mac says.
Ice packs are pretty common - look in your local drug store or athletic supply store. Commonest reaction is mixing ammonium nitrate with water. If the water coming out of your tube need not be pure, consider mixing the nitrate directly. Um, caution: buying large amounts of nitrate may get you questioned by authorities.
