DIY cooler box (mini fridge) Peltier - Part 2/3 

Hats off, you're the only true specialist that truly and effectively made use of peltier modules to cool. I am looking to build an air conditioner with peltier modules and i hope your design will be of immense help

This is the real peltier fridge u r really the best in technology ,idea,innovation ,precision and simply the best 👍👍👍👍👍

I love his humour, Cold as my fiance's heart And this Is my fat cat Lol

That Carlsberg Lime Soda looks amazing. I might just have to build a fridge to keep mine cool. 🌨🍻

Very nice project. Very clean assembly! Well Done! Think I'll try one myself:)

Well made fridge. Like the attention to detail in the build.

I really love your video's, and your humor.

Glad to see you are bringing the Pilsner to 8 degress. Ideal drinking temp

Excellent idea about the cold air running out of the open door on side mounted fridge doors. Just think of the wasted energy in our homes with the way our refrigerators and freezers are designed. The old style deep freezers had this right. Very nice build.

Thanks for showing stacking Peltier modules to get a lower temperature.

You do some very nice work.

I really did think you're going to make a part three for a second. Lol great video series. I'll have to try to make a mini fridge now.

great video,,very impormative as always

Good job, Sorin!

Genial!!! I didn't know that DIY can be so fun!!!

Thank you for this awesome video

Perfect timing! I'm about to eat my dinner.

Yes part 2 is awesome conplete detail

Very very useful video,, lot of thanks to your hard work...

Great work man 👍🏻

Impresionante trabajo compañero....Toda una obra de arte la verdad....El único inconveniente, es el gran consumo de corriente que tienen estas células peltier....Un gran abrazo....

LoL Cold as my fiancee heart. OMG to funny and... he showed us his cat too. Awesome build sir. Thinking of making something like that to go camping but a bit bigger.

Big like, congratulations!

bravo sorine... esti fenomenal

Amazing as usual

Very good project Sorin. I order only one peltier element before see your videos but will order second one. And my cooling box I will make all with copper sheets instead of aluminium 😉 Cheers!

this video is a masterpiece, thanks for share!

Switching only one of the Peltiers with the thermostat , and keeping the other one on permanently is a very clever engineering idea. Provided that your desired temperature range requires at least half of the cooling power. Your set temperature can not be too close to ambient. Mostly that will not be a problem. You are so right that a lot of video's about peltier cooling are ridiculously optimistic.

8:12 warm your paste with a hair drier before final tightening. This changes it's phase to a liquid and allows better tightening for better result. Also, you applied a lot more than needed - this reduces net thermal conductvity. About half as much next time for that size. Thick paste=bad

Very useful project I like this😄

Foarte frumos! Felicitari

nice work, keep it up

The one that has waited for

Creative video, thanks :)

So pretty. Thanks..

3:40 Tabla Aluminiu :)). Fain proiectul. Felicitari!

You are a genius frate !

Very awesome projejct. I wish i can also build one

you can use a 6v peltier with 12A in sandwich formation and this will help you get -15 temp inside and with normal heat outside .... means you dont need bigger cooling

I love ur accent & presentation.... It's as cool as ur mini fridge....😀😀😀

Cold as my fiancee heart , sick burned

May be the drinks are colder because the temperature can transfer efficiently or better to some solid objects than air. Which in this case, the bottom of the can is touching a solid part of the fridge.

Felicitari, mult succes. O alta idee , daca vrei sa o realizezi, ar fi sa folosesti 1-2 Peltier, ca sa faci o racire auxuliara pentru PC, adica pentru racirea procesorului de calculator. Dar pe racirea cu lichid si modulele Peltier, sa raceasca radiatorul exterior. Spor.

hahahahha you're so funny man! Thanks a lot for your video, very professional job!

Outstanding!

Just had a question. Wouldn't a small cpu fan placed inside the fridge help in creating cold air?

that was cool

U deserve more subscribers

Very good 👍

You are a genius

Next Episode: DIY lapel mic.

good work !how do we determine the time it takes to cool one liter of water from 25c to 4c ? b/c i am trying to design small fridge like you. please help me

OMG you awesome ive been here since 10k subs or before i hope you start uploading more videos please your almost 50K!!

Good stuff

Very neat

Ma bucur sa vad un proiect, bine documentat, din partea unui conational. As face totusi doua mici modificari. As muta distantierul de aluminiu pe partea fierbinte, unde am nevoie de inertie termica. Pe partea rece acest distantier se comporta ca o rezistenta in calea caldurii, intarziind si limitand racirea. Trebuie probat, nu sunt sigur ca am dreptate. Si a doua sugestie este ca as pune ventilatoarele in serie si fara diode. In felul acesta as reduce consumul lor si mai ales uzura si zgomotul. Bineinteles ca RPM ar descreste, fiind alimentate cu 6V fiecare, dar nu cred ca aerul fortat cu ventilatoarele la maxim ar face prea mare diferenta. Am sa imi fac si eu un racitor de acest gen, chiar asa cu 2 celule. Am in cap sa folosesc un management al temperaturii radiatoarelor la exterior si sa le dau drumul alternat, la celule, cand diferenta intre ele ar fi de 10 gr C cel mai cald se opreste si cel rece porneste. Ventilatoarele le tin pornite continuu. Initial sa mearga amandoua celulele, pana se raceste in interior, apoi cand una cand alta. Celulele sunt mai eficiente cand sunt bine racite pe partea fierbinte.

If you are planning to do more of these..... 9volts seems to be the best maximum voltage for good efficient. Using more like 12volts starts to create extra heat. You should try out stacking them, like 9v+5v+3v. I am currently using 3x12706 modules, running them at 5v+5v+3.6v and was able to reach -31celsius measured from top of Peltier. Those 3 units use total of 27watts. I did my first test today and seems like the box might be too big (25L), i still have not build a proper door for it, but in 1h30mins it cooled down 9celsius from 21c --> 12c. It is also very important to measure your temperature outside the box wall, to see if the insulating is working good enough. For example my 25L box starts to leak cool air after it hits 12c. 0.4celsius is getting thru the insulation which does not sound much, but when there is a lot of surface it adds up. But all in all, i have watched a lot of these videos and i must admit yours is the best one so far.. Good job.

Very impressed with your work! Can this be made or redesign the working principle for car air conditioner as a separate air conditioner unit .. . !? Please make a project... Like cool air for passengers and utilise hot air for defogger for the windshield.

Good job. La interior panourile de aluminiu le-as fi unit cu acel cornier pe spate, cu suruburi cu cap înecat pentru spatiu sa nu fie incomod cand pui ceva la rece, sa te agati in suruburi. Acuma tu au facut cu racire pasiva la interior, eu as fi facut cu racire fortata, un radiator cu ventilator, sa circule aerul la interior si atunci ai o racire mai rapida(parerea mea). Se foloseste si la frigiderele din casa astfel de racire. Frigiderul meu din casa are ventilator in interior si plimba aerul incontinuu cat timp este usa inchisa si se opreste cand deschizi usa. Pe acest principiu este si lada mea frigo. Raceste repede ca plimba aerul la interior. Inconvenientul ca face putin condens si ai nevoie de o scurgere sau din cand in cand sa sterg/scurgi apa. In rest nimic de comentat. Explicatii la greu si asta imi place. La cat mai multe proiecte. Numai bine!

Very cool project, I might make a shittier version of this as a campervan project 😄

Thanks for this video it was very instructive . what kind of solar panel can keep this fridge going

The fan on the hot side must be turned upside down to blow hot air out. Inside you need to install a small fan so that there is air circulation. 12v small ice more hot. 10v maximum ice, minimum hot

Great work. Thank you for sharing. Did you have ice buildup on cold panels after a few days?

With a progressive tap set like in the video, if tapping aluminum you can simply put the thing in a hand drill and run it through.

Next video peltier ac 👌👌👌

Great job! I've built something like that but the issue with peltiers is that as soon as they switch off (temperature reached) they introduce heat from the outside heat sinks causing the temperature inside the box to increse quickly. Have you got the same issue? Or am I missing something?🤔

Not exactly how I to drilling and tapping. However your system works fine. The way you explained how you did the drilling , tapping. Safety was nicely done. I would like to suggest this to be made ( once all if any changes are made ) available in a kit form for sale .

That easy to make

Awesome!!!

Amazing video So i have a question in my country the temperature in summer is about 40 t0 45 degrees outside in room its about 30 to 37 degree So i will need the more powerful modules? Will peltier 12715 model work in that high temperature? But it have high power consumption Can u please tell me which one.i use to get that low temperature? Water cooling on hot side? Thank you

Any recommendation for what module to use, swapping out a condenser on mini fridge to thermoelectric? Need the minifride to hold Temps between 65 and 72 degrees F. Thank you good sir, love your videos!

Best ideas

Very informative...i am currently doing this...but i have a question...can i use 4 peltier modules instead of 2? And can i use a 12volt laptop charger as a power supply

Really cool video, well explained, and I like the well-thought design. Just found you channel and subscribed 👍 A question for you - what would it take to create a freezer? My particular use case is making ice cubes.

At 7:50, you showed your curcuit diagram. I saw that one of the peltier modules are always connected to power (the right one) and the other is only on when the relay is on. Is there a reason for that? And which one in the hardware should be the one that is always on?

Will you please make a video explaining how to use computer power supply in this and how to make that car power cable.....I really want to make it!

Would love to see a 12V airconditioner using same principle.

Génial. ^^

Loved this. Your jokes are too funny! Is there a video on how you've made your soldering rod or did you buy that?

nice job i pretty much did the same thing though mine could only reach 5c due to the fact that i got ripped off with a bad quality peltier.

Good idea to only hook up one TEC to the thermostat.

Oh man, I've done EXACTLY the same thing, only on a budget. One peltier, 5mm MDF and 5mm Insulation foam pads, and as you can imagine it's not so effective. There is also one small inside radiator. Two 0.5 -beer- soda cans can fit in there. I also plan using it in the car and have made the same extension cable. Btw, are those lights in your car stock? Bc I also happened to place RGB LEDs in my car xD

Have you considered using tower coolers instead of those old AMD ones? They are vastly superior in the amount of heat they can dissipate.

Love you r Experiment

Hey Sorin, can you create a portable Airconditioner from this same peltier module as well please? That would be awesome!

Thank you for this awesome video, can you make a video on how to build and air-conditioner I am quite sure that there are fake videos aswell on youtube

do you have a blue prints for this??? and a list of all materials

you should add another heatsink with a small fan inside the fridge

My room mate heard your joke about the ice cold fiance, while he was in the fridge. We both laughed, especially funny the casual way you say it while she is opening the fridge door for us. Do you make any projects using Peltier modules to capture heat/cold to use for electrical uses? I have a wood stove and the power goes out in my small villiage often. I could use it to charge my phone... I am trying to avoid fake vids Hard to tell the difference sometimes. This channnel has substance Thank you Sorin DIYEN

You don't need to spread thermal paste, it will spread out itself as you put the heatsink on.

Salut sorin,tu de unde cumperi componentele?(gen module,sau cooler sau dastea)

use coconut oil as lubricant for aluminum tapping

how many peltier should I use for a 50x45x25cm box (inside measure)? I can put 20/30/40mm thick insulation on all sides if needed. I would like to go about 8°C from 28°C ambient temperature, at least should achieve 16°C

Well, that´s mostly quite easy. I just keep stucking at 13:34, can´t manage to reproduce that time handling.

Can you make a version with watercooling for hot side?

why not put some thermal mass like a layer of thin concrete inside the space?; this may limit temps fluctuation when peltier's are off

please do a desktop mini freezer that can store frozen goods like ice cream. i want to have one for my room and in dining area. thanks

The difference btw two measure is because of liquids transfers the heat more than air also propagate their heat to air

can be fan runing inside for 0 degree below or its dangerous to short?

Salut, de la ce "hardware store" ai cumparat tabla de aluminiu?
