I've used Peltier cooling. It works very well. You epoxy the Peltier device to big chunk of aluminum with embed thermistors. The controller servos the Peltier current to keep the thermistors at a setpoint. You can get to better then 0.1C that way. Problems: (1) This will use a "ton" of electric current. (2) You will need a huge heat sink on the side of the Peltier not facing the device to be cooled. So huge that you will likely need for it to be a water based system with a pump Good news is that Melcor sells everything you need, the peltiers, heat exchangers and so on. And they have all the technical data you need and tutorials too. Also the exact same Peltier setup will either heat or cool You will need a lot of very good insulation. Specifically to prevent heat from flowing between the two sides of the peltier. We used vacuum because it is very effective but it is expensive and complex to maintain. You would likely find spray in place foam to work and the stuff is cheap and easy to spary between the hot and cold side heat sinks OK, my point is, yes it will work but it will be far from cheap and easy -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
