Thank you for the video. I work in a laboratory and have to replace a Peltier that is used in an instrument. I wasn't sure about a couple of things but your video really helped. I saw the message below about paste coverage. Thanks for your help.
Thing is - peltiers are ceramic and contact with paste should be spread all over rather than squeezing like a CPU. Its ceramic not metal so heat is not spread out well on the peltier irself. Your heat transfer potential is only maximised around the point of contact through the paste. Therefore, you have diminished conductivity from the ceramic surface to the metal surface by having the paste only on some of the peltier suface.
Right from corner to corner Never apply paste like that . Any warranty would be invalid based on improper installation.. first clean all surfaces to be in contact with alchohol, it removes all oils. Then apply your paste in the proper manner. That bs he is doing is some bestbuy geek squad thing. HP MasterTech Dell sys expert i no a lil somethin ...

Peltier devices are very power hungry. You will need a lot of power generation and storage for your plan. Think like car battery size storage at minimum.
it doesn't matter if you touch it, its not sensitive, he is for some reason saying its not OK to touch it, if it gets dirty, you can clean it with iso alcohol.

Usually you see a drastic decline in cooling performance when a pelter fails, not the other way around. From what I've seen while studying how pelter based refrigeration units work, they are very simple by design. Basically you have your pelter unit, a power supply, a 12v pc fan, and a switch. The units with "temperature" controls don't really have a means of adjusting the "cooling power" of the pelter as its basically a solid state heat pump with a hardware set efficiency. So on temp control units, its either just a placebo, or it just simply turns off the pelter until the internals warm back to the desired temp. That being said, what I theorize is the issue in your case, is that the ambient temperature in the room is cooler than what the manufacturer designed the fridge to operate in. Because with pelter units, up to a point, will get colder depending on how well the hot side is cooled.
@reluttr2 my thought was the temp sensor in the unit was faulty. Turns out it was so it would run constantly never stopping at the desired temp. Ran a new temp sensor and that did the trick.
@@ravibarot7867 I had a bit of a look, ripple voltages within the Peltier operating range won't hurt it, but will reduce your power efficiency, so adding a decent capacitor would likely improve your cooling slightly.
If I take TEC1-12706 peltier module and I gave to it 12volt,6amp at room temperature 35 degree Celsius then after 1hour what will be the min temperature at cold side and max temperature at hot side.
It will try to maintain about a 60c difference. The hot side will get above 35c by a lot. Bascially the cooler you can keep the hot side, the cooler the cold side will be.
I don't know the exact model, here is a pic of teh dimensions of the ones I have used: ae01.alicdn.com/kf/HTB1eWOIa6DuK1RjSszdq6xGLpXaK.jpg?width=1080&height=1080&hash=2160 The smaller you go, the less efficient the peltier will get. Getting rid of the heat is the most important thing. :-)
I'm not sure what you want to achieve with a PCB. Cooling a circuit board is usually best done with air cooling, Peltier devices add extra heat to disperse.
Do you have a multimeter? It sounds like power supply is being pulled low. I have seen fake power supplies do this. A multimeter will tell you the answer. If you have another power supply you can use it for your fan. Just be careful, if the power supply is overloaded it may self destruct!
@@DrBlackAdder peltier + fans was on the load port of a solar mppt solar charger instead of directly on a battery. Clamped directly to the battery, it works :-) But the solar regulator is not a cheap one and should let 10 amps through. Only the one fan isnt working on the load port lol

All depends on the quality of insulation and the temperature of your environment. I'd expect it to work ok on a 40-50L fridge.
