Making a water-cooled Peltier Dehumidifier DIY

- Welcome to my channel, today I made a water cooled dehumidifier. Traditional small dehumidifiers available in stores are inefficient, why? Because the peltier module generates a lot of heat that must be dissipated. Small heatsinks don't do the best for this. That's why I designed a water-cooled dehumidifier. I printed the water block on a 3D printer, it is powered by a small aquarium pump. Its advantage is high efficiency compared to traditional devices and noiselessness. No fan needs to run to cool the heatsink, just a slight hum of the pump.

Do i need to power off the peltier for dropping water from heatsink after It's gets cold or the water will drop
Automatically.?
epic timelapse , good job
Thanks
Nice. Did you share the files anywhere so I can try to make one?
What kind of water output did you get?
Why isnt there humidity measuring for every diy dehumidifier? They always show temperature measuring which is not the purpose of the diy.
the best!!!
The block is cool and you printed it? I take it you have no issues with moisture in your fillment no? Ive been wanting to make one for my rolls.
It is more efficient to use copper on the cold side
Have it water cool it own water
A dehumidifier is most efficient when you heat up the air before it reaches the cool radiator. - it makes the air absorb extra moisture from air outside the system.
The problem with peltiers is they don't have enough space between each phase to allow efficient absorption. So water cooling the hot side, could be a good method to move the hot radiator, closer to an intake of the system and further away from the cold radiator. (And defrosts the device during time it's interval off cycle. Since peltiers produce more heat than they move.)
One thing I've been exploring is whether there is a benefit of forced air flow. If hot were on bottom and cold on top. The heat would rise super quick to fill in the lack of energy. And it should suck ambient air into the system as it rises. Along with pushing the rechilled air above, back out.
(Not easy / efficient to move heat downwards with just air. You pretty much need to put the heat energy into a liquid.)
3D printed plastic parts are usually not watertight. TO achiev watertightness you would probably need to paint the part
Water coolind looks an overkill for this application. Moreover - your water bucket will need to be cooled as well. So it is rather heat condencer than heat dispenser. Simple fan would be much better I think
Ideally, the cold side should be just above freezing for maximum condensation while avoiding frosting. It must be cooler than the dew point for dehumidification to occur. A fan that passes its cold air to cool its hot side would help accomplish the goal. That's a 3D design idea!
Have you tried this to make a dehumidified dry box to print from. I’m currently working on a dry box to print CF-PA from.
