-60C Peltier Cooler

Uses 2 stacked Peltier modules the top run at 7V and the bottom run at 12V. The bottom is communicating with a radiator cooled water block using thermal paste. Two such stacked arrays are side by side on the cooling block for a total of 4 modules. The array easily gets to -60 degrees C.

I've been looking for information on the use of peltier cells and the best way of cooling for 4 days. Without a doubt your proposal is the best I have found, thanks for sharing. A pity that I can only give you a like, I would give you thousands

[ambush]

Water cooler better and both peltier you give it 3.3v 10a?










Tech?

[simrandeepbahal]

Nice video. Are the two peltiers connected in parallel?

[dragonbot]

Wow! Where did you get that water radiator cooler? Can you post a link? Thanks!

[FuSD]

That is not the correct way to use an infrared thermometer

[fireandforge]

Have you thought about using peltier cells in a sand battery?

[jessicavoruda]

Could you explain why you're using 2 different voltages? Or is it just a matter of available voltage leads/sources from your computer power supply. The temperatures are impressive! I understand you can push power further with pulse width modulation. Trying to learn more about that separately. I'm interested in building a small freezer. Attempting to get temperatures -30F if possible using multiple Peltier elements and proper cooling. Do you think it's possible within the easily achievable limits of the elements?

I know there are different types of peltier modules. So I ask are you using peltiers that are specifically made for those [12v; 7v] voltages or are your just using all 12v's and running the top piece at 7v?

[krisg]

Can you explain why use 12v and 7v ? Both 12v isnt OK?

[detonart]

Very interesting setup! I'm intending to mount a similar one, but inside a vehicle, so I will have only the battery 12v to apply on the system. What if I connect the bottom peltiers in parallel and the upper ones in series? Should I get a result near of yours?

[alq]

Where did you get the high quality units?

[katiekumcgil]

heya awesome would love to see some meter readings of volts and currents, be interested to see the side by side stacks wired in series to this should lower the current conciderably

[angusmcgil]

im pretty sure that the single fan radiator would have very quickl;y become over whelmed and heat would start flowing backward, to sustain it over time id think that 2 x 3 fan radiators would be required

[sciguy]

Impressive. I figure that, if you completely closed the cold side and made heat management more efficient, you could make dry ice with this. Dry ice is around -78 C, not too far off. Good video

Ok I'm back.... I've been trying to replicate this but cool a 40x80 heat sink as well I've got a pc radiator 3fan and...think I can barely get it to freezing...bottom 12v top at 7...hmmm think I should add a third cascade and slap it in middle at 9.5volts?

[mohimadvani]

very impressive. this would be the only video which is done keeping in mind the limitations of the peltier. I have seen so many videos about the peltier, none of them understand what they are trying to do. excellent job.👍👍👍👍👍👍👍👍👍👍👍👍👍👍❤

[erlinghagendesign]

which temperature has the liquid inside the tubes and inside the bucket? Are you using water or anti freeze liquid? Which proper way would you suggest to control the liquid temperature so that you can set it to a ~constant temperature, for instance with a PID controller?

[chatorasinn]

please demonstrate full project, which number peltier you used ?

[andreavela]

yes you can really make an air conditioner with the peltier cell? Because 60 degrees below zero is not bad

[amikosik]

What is the purpose of having 2 Peltier modules stack on top of each other?
