Goliath dealt with condensation by simply cooling the air inside the case to the same temperature as the liquid running through the loop; therefore, negating dew-point and condensation.
The OP here expressed that he wanted to have the components inside a case where the air is vacuumed out...
The issues I see with this method:
- Creating an absolute/perfect vacuum is impossible; at least for normal folk like ourselves. Best we can hope for is a partial vacuum.
- Going with a partial vacuum still leaves air particles inside the enclosure and therefore a chance for condensation.
I'm not trying to shut the OP's idea down... I'm actually very interested in seeing something like this happen as it would be the perfect way for subzero benching; I just don't see it as a very viable alternative... I think cooling the air in the enclosure (like in Goliath), or replacing the air with an inert/dry gas is a much easier way of achieving the same result (no condensation).
I just got to page 14 on that thread and found out he did vacuum out the air, but he also re-pressurized the chamber with Nitrogen.Edited by xXSebaSXx - 8/27/11 at 6:11pm
