Thermoelectric Peltier dehumidifier

[darrellwood13]

Theoretically: If an old-guy were building a sailboat with the intention of sailing the world for the next several years and building a PC that would survive extreme heat/cold, high humidity, as well as salt air environments, do you think it would it be possible to build a Thermoelectric Peltier dehumidifier in a low heat (>300W) semi-sealed PC?

Extreme Heat and Cold to you and I is pretty much nothing to a machine. As long as you're not way, way below freezing the PC will boot. Cold boot failure is very rare and only happens when people use liquid nitrogen to cool their CPUs for events.


Extreme heat is the same thing, the hottest place on the planet, the Lut Desert, hit 70c this year. This is still a solid 20degC than most computers are happy to run at. They will run at higher temps but complain about it.

Salt, well - there really isn't much on a PC to corrode. PCB is immune, gold is immune, aluminum oxidizes but not like that, copper would be a problem so be sure to get nickle plated solutions.

What is the real purpose of the Peltier? I'd be worried having such an advanced cooling system could cause system failure when the system itself works fine, know what i mean? If your Peltier system craps out - your computer is effectively dead. And i do believe the peltier would be the least robust part of the system.

I think that would be possible ,the Peltier cold side would need to be mounted to a metal plate for the moisture to condense on, then this condensate would need to be drained to the outside of the case.
Personally I would build the PC into a fully airtight case then water cool everything with the radiator mounted outside the case.

I still feel like having a PC that requires power is bad enough - having a cooling system that also needs attention is just adding problems before the solution.

Just get a marine PC case. They make them.
