View Full Version : rambling idea for homemade Peltier based water chiller

So I was just in Texas for a maintenance class for the new litho toolset i'm working with, and it has a pretty fancy Peltier based water chiller.

As a result I'm thinking i want to make my own. More or less as a crazy project for me to actually use all the general chemical engineering crap i got in school that doesn't get taxed working for Intel.

My basic goal is to create a system for water cooling that i don't need to worry about prepping my board for condensation, but it maintains the lowest possible temps without that extra precaution. So I can have all sorts of fun working out a process control system for a feedback loop between temps and pelt voltages. Tack on the fact that I have a friend who has a home made computer controlled milling machine and I also can play around with making my own heat exchange assembly.

So the final question all boils down to... will this idea just end up being inefficient and unnecessary? I love the idea of the project, but if i'd be better off just putting a pelt straight on the CPU, it'd probably just be easier to do it that way.

I would like to know as well, you could try submerging the board in liquid of some sort and cooling the liquid with the TECs. I would recommend DSI Fluids OptiCool transformer fluid which you can find at www.dsifluids.com but I believe the water "bong" method of evap cooling is best for cooling larger (437 watt) TECs

haha, i'm not wanting to go that crazy. I was thinking more along the lines of temps just above dew point.
