Watching your videos helps refresh my memory, helping me see light through the fog of time. So much of the schooling i did over a generation ago has gone to waste. Thank you for the refresh.
You did a very nice job, 23 minutes to 15 is impressive, especially for a peltier. I just got a 20L compressor driven cooler, and it actually uses less electricity than a peltier individual bottle cooler.
If you place allready cooled bottles and add a microcontroler to control the fans and peltiermodules, you can drastically reduce noise while you ensure to not get frozen grape juce. I made a fermatation box with peltierelement, microcontroler, MOSFET and temerature sensor. I programmed my first PID-controler for this, and it works quite good. A proper controlstrategy is more energy efficient, and keeps the fan speed nearly constant, which is less anoying than switching on and off all the time.
For a brief time in the late 90's, at my local grocery store appeared a freestanding wine chiller. It was the size and shape of a barrel, and it had an ice cold vortex of water circulating in it continuously. The idea was you'd pick out your bottle, place it in the cooler, and do some shopping, and within a few minutes the bottle was ice cold.
al foil tape on the hotside of the mdf panels would reduce the thermal trasnfer between the air gap because shiny al has very low emissivity which is the dominate mechanism for thermal losses from the cold side. I bought some 12v dc compressor fridges and covered the outside of them with AL foil tape which improved their efficiency by around 30% because they flick the thermal emission of the warm room away, you can even feel the difference. i have a poor quality video on my channel on how to reduce the power usage of a 12v fridge down to ~100wh/day which is like 20x better than a regular fridge.
Nice job man! but i'm curious: what do you do with the condensate inside? that ice, after you turn it off, will melt and end up on the inside of the device...or maybe on the table :)?
The box is insulated with laminated panels, vinyl and extruded polystyrene. There is very little condensation, it will remain inside and will evaporate pretty fast, because there is a big hole on the top. Ice is forming only when testing it without a bottle. because if a bottle is touching the cold radiator, it will absorb the cold temperature and the radiator will not make ice anymore.
Impressive video, Sorin - DIY Electrical Nerd. Looking forward to seeing more content from you. I hit the thumbs up symbol on your upload. Continue the fantastic work. Your DIY bottle cooler project is both creative and resourceful! How do you think the insulation thickness affects the overall efficiency of the cooling system in practical use?
Thanks! The insulation depends on the type of project, for a bottle cooler 2.5 - 5mm insulation is enough, because it's not a closed enclosure. But for a mini fridge or a freezer it needs at least 10mm of insulation. Before finishing this bottle cooler I made some tests with no insulation between the cold radiator and a thin MDF panel and it made condensation on the outside of the panel, so it definitely needs some insulation.
Salut, bravo pentru treaba depusa, insa vin cu 2 intrebari: Mai ai acel seat 1m? Daca da, vei mai posta videoclipuri legate de motorul de 1.6 16v pe canalul tau de mecanica?
Because the bottle sits on the cold radiator. That's why I designed the box at an angle. There is no need for a fan, the temperature transfer is much better from the aluminum radiator directly to the bottle.
Excellent project, something like that I had haganas to see, about the fans, I guess you can reduce the size to make it a quieter. I think the Laptop ones can work..... Regards
I think a 12706 module would have been better for this if you want to cool the drinks more quickly, they are less efficient but will pump through more thermal energy away from the bottle. Though 150w for just a wine chiller would be quite extra.
"If some of you actually bought a real wine chiller, tell me how fast works in the comments"... Nope! No one who watches a video with the title 'DIY Wine chiller / Bottle cooler' would ever buy a commercially sold wine cooler. Don't hold your breath!
I have never deleted comments. You are right, these Peltier modules should be powered with a constant current of maximum 3A each and maximum 6A in total, because they are connected in parallel (6.13A including the fans). So what's the wrong part?
@@Sorin_DIY Well my comment was deleted somehow. I referenced to my comment on the peltier test you made some while ago. The wrong part is that the voltage on your power supply staid the same and the current changed. That is a clear indicator you running them on constant voltage instead of constant current. They are less efficient this way and therefore consume more energy. I looked in the datasheet and would say around 30% more... That's why I suggested to repeat your test with CC instead of CV. Wasn't intented to be harsh, but have to say I was a bit shocked my first comment was deleted (by whomever).
Constant current means you can limit the current to a maximum value, not to force a load to draw a fixed current. for example if you have a variable power supply and you set the voltage to 10v and a constant current of 1A and you connect a 100ohm resistor as a load, it will draw 0.1A. no matter if you set the constant current to 0.2A or 10A, the load will still draw 0.1A. Ohm's law is I=U/R, so 10V/100ohm= 0.1A. It's the same for peltier modules, this module draws about 2.8A at 12V. you can use a normal power supply, or a constant current power supply set to 3A, the load will still draw 2.8A. but if you increase the voltage, then you need to limit the current to 3A, otherwise you will damage the module, because it will draw more current. You can watch my Peltier test 2 video, where I used a CC power supply.
@@Sorin_DIY I respectfully disagree. A true constant current (CC) power supply maintains a fixed current by dynamically adjusting the voltage to ensure the set current is delivered to the load. If the voltage isn't adjusted to achieve the target current, then it's not operating in CC mode. Some power supplies allow setting both maximum voltage and maximum current, and they will prioritize one limit based on the load-this is more of a dual-mode operation, not pure CC. As for Peltier modules like the TEC12706, their 𝑄𝑚𝑎𝑥 is specified at 16.4V (not 12V) because they are designed to operate with specific current values, and their performance is optimized when the current is carefully regulated.

Ive never been so excited in my life.... That is until Sorin said 'oh yeah, much better now." 😅

IIt's a good design, but I think it's worth adding a temperature control solution.
All that's left is which wine to choose. 🙂
Multa sanatate Sorin!
And now let’s drink some “grape juce” ❤ very good video as usual !
May I suggest you do a DIY jet fan blower

Very nice! One addition I would do is to make the insides waterproof, like put a plastic lining.
Good stuff, thanks!

I want this bottle cooler!
Lovee u from Pakistan! ❤

Why don't you add a tiny fan in the cold chamber to circulate the cold air so you can achieve faster cooling than using the convection method?
Because the bottle sits on the cold radiator. That's why I designed the box at an angle. There is no need for a fan, the temperature transfer is much better from the aluminum radiator directly to the bottle.

nice if put the bottle cold, will stay long period
'Soda' chiller 😂
lets cool this bottle of uh uhm water😂

Even if my comments get deleted, you still using them wrong. Might scratch your ego but still they are designed to be used with CC

Hey bro making a phone cooler use peltier module and also lightweight design
What did you say to your date?
I'm glad she's with me... and we are having a romantic dinner, next to this wonderful DIY wine chiller :)
❤❤🩹
First
wow, you must be so proud
