[Amps] Getting rid of blower noise - an alternate cooling scheme using the phase transition of liquid carbon dioxide

[Peter Chadwick]

If you order your liquid CO2 cylinder with a dip tube, you gte liquid CO2 without having to have the cylinder upside down.
As said, you need to watch the CO2 concentration. We used dip tube CO2 cylinders at work for cooling ICs in small thermal chambers, and started finding that on occasion, we could start getting very dopy because the concentration got too high. Working practices got changed immediately!
