love it! you could also add a small fan inside the freezer to speed up cooling for the whole inside region. sinking the magnets a bit deeper into their holes would also increase the efficiency of the system.
The best would be to have a copper bottom linked to the cold element, this would cool the drink much faster cause it would be in contact with a cold surface... he could just bend a copper or aluminium sheet in U shape with enough space inside it for the can and then connect the peltier directly to it. Many ways to improve this design but it remains a good basis.
Obviously, yes, but were you searching for a video on how to build a freezer from parts cheaper than a ready-made one? Nothing in the title or description should have mislead you to conclude that was the point of this video.
Out of every mini fridge tutorial on the youtube,i like yours for you provided the best logic for attaining the lowest temperature. Although a low temperature can also be achieved by using a high quality peltier but dissipating the heat is as much important!
To improve this design I would make it a top opening freezer. This way the cold air would not escape when its opened. And I would also try making a roller for the drink to lay on and slowly roll. I think it would cause the drink to cool faster. Perhaps a small fan would help remove the heat from the can while helping keep the air as cold as the heatsink.
Somehow this isn't seem to be working with me. I'm trying to make an icebox freezer, my cold side doesn't get to freezing temperature. It's abt 15 degrees lesser than ambient temperature. Not even close to freezing. I've tried using different 12706 peltier modules but none have been ice cold they only go uptil condensation point. I'm using 12v 5a power supply. Can someone help?
12v 5a is not enough. Also you have to consider the volume of your cooler and proper insulation. 12706 is a bad module. Use 2 pcs 12703 module with 2 cooler fans. But keep in mind that it needs time to cool down depending on the amount of things you put in.
Please DO NOTE that ambient temperature also affects the cooling. I've tried copper heatsink with 2A blower fan only gave me 13 degrees at the lowest. This was at room temperatures more than 35.
Oh my gosh this is perfectly the kind of tutorial I was looking for! I have a little camping battery pack that can hook up to a turbine or solar panel which I'm going to use in an e bike camping trailer. For most of my food I can ferment for preservation and eliminate the need for a "micro fridge" in the camper trailer but if I had a small volt efficient freezer box like this video's really inspiring me to build-,something the size of a small microwave oven box then I could "refreeze" ice packs basically indefinitely for the lifetime of the battery pack and have year round food (refrigerated fermented foods can last for years) Thank you so much for giving me the fundamentals RC Life I appreciate you!
Back in the 80's I bought one of those from Sears that cooled or heated depending how you plugged it in. It didn't do good either way, and killed a car battery. You could drive down the highway with it on and when I parked somewhere and turned the car off I always had to get someone to jump start the battery. Maybe the newer ones are made better.
maybe a good idea would be to add a thermostat, so the freezer shuts of when its cold enough, and strats back up when its to hot. that will save you a lot of power. and also, does the fan make a lot of noice? nice project man!
i just subscribed , this video just made me want to make my own freezer. .. even if i dont i wonder what i can build if i put my mind to it . this video reminded me what it is like to watch useful things and learn something new every.
If you put a relay into the circuit and use a thermostat to control the switch in the relay, it will turn on and off by itself and you can adjust the set-point to any temperature you want! That's how a lot of refrigerators work.
Possible improvements: 1) Foam is fragile. Only use it as isolation and put the whole thing in a wooden, plastic or metal box. 2) While foam is great for DYI aerogel is better. 3) Put in a internal fan in order to more quickly cool the freezer. 4) Make it slightly bigger.
i did this myself for dads day but i build a lager box and used 3 peltier parts. it works but i had no time to install some regulation elektronics or sensors so it was always on by full power.
I made something a little larger that used solar power that's used on my cabin, based on some design I downloaded years ago. my point is this is much cooler than mine! no pun intended.
That goes both ways. With moving the air, you also decrease the effectiveness of the insulation since you increase the thermal transfer of all surfaces. It's best to take advantage of the natural convection, warm air will always accumulate at the top, be cooled and fall to the bottom.
Really nice video and good work on the freezer. I may try this at some point. Potentially when my children have left the nest... In about 16 years minimum... (ages 4 and another 8 weeks)
your a young genius ! , i like people like you who always try to find new inventions or cool stuff to be build , i use to be like you when i was young you can believe me , don`t stop its nice to see new talented people with cool ideas !! ,,, i will build one for camping !! thanks young man
just to inform you, this is not new, you can find much of this freezer concepts on the web on some technical boards if you do a quick research with google....

When you powered the cooler with a battery, did you use any sort of current limiter or power regulation beyond the PWM? This might be a mistake, I'm not sure. Certainly it would be without the PWM. With no power management at all then these things will burn up when hooked to a battery which can supply giant amounts of current (especially lead acid and lithium). They will chill for a minute or so before both sides begin to get hot. They are fine running on those little AC power supplies because they are self-limiting in the amount of power they can deliver. A battery is not self-limited (at least the internal resistance is so low that the battery will get hot enough to explode before that resistance becomes a significant factor). I learned his the hard way when I replaced an alkaline battery power pack with a lead-acid battery. I felt pretty dumb when I realized what I had done. The coolers survived the ordeal, amazingly.
I have watched a lot of these kind of videos. Why people don't use 2x stacked peltier modules? I have done testing my self, and when stacking 2xTEC1-12706 you can get to same -11c only using +5v/2.4A. That means i could use just a normal USB charger to power it, which makes it much more easier to move it around. Also i could use those 20,000mA chargebanks to power it for long time, like when you are in a beach..
Go for custom Heat sinks. Will cost you little higher but beneficial in the long run. Also use large and high rpm fans. Sound can be bit annoying but you can place it somewhere you don't sit usually.
Summer time is coming here in the Philippines. Can you please make one - like an electric fan that exhaust cooler air using this kind of technique in cooling
I could be wrong but I think the efficiency also depends on the cold side flow of energy, because the device works through the concept of diference of temperature on both sides. The cold side has a temp limit because we are talking about semiconductors.
He probably messed up the shot the first time. I am sure he measured first, then polished up the shots after. There is more to a youtube video than turning on a camera.
very nice, I just got a 6 pack cooler/fridge, that thing had the cheapest aluminum heatsink to dissipate the heat, but it didn't expose the cool side, it works but I'm talking days, not hours, and not minutes (in fairness your design has room for 1 drink vs 6) but I'm definitely modifying your design, not theirs if I do my own! I would suggest a simple blower fan pointed at the cold sink, and a low profile heatsink from a U1 server, just need to make sure a fan can mount on the top
Looks like you could take that and apply it as a lid to an existing cooler. That way you have a rigid base and, with a little creative printing, make an insulated top that cools down the contents without needing ice.
6Amp peltier with a CPU fan and CPU heat sink will never get down to -10C. i test it with ice for hot side (Freeze the hot side in a water container in freezer) the temp of cold side was -12C. you just use a fan and heat sink and get to -10C ? its not possible
Amir, using an ARCTIC Alpine 11 Plus CPU Cooler (www.amazon.com/gp/product/B00606OHQQ/ref=od_aui_detailpages00?ie=UTF8&psc=1) I was able to get -12.3C from an 12706 module (driven at 11.6V, darwing 4A). Pushing supply voltage to 13.6V/4.7A only decreased temp to -12.4C, so I knew I reached an inflection point. Hot side never exceeded 36.8C. Temps were measured with thermocouples (using IR gun is not accurate due to wide optical window and dependence on surface reflectivity). Best temps were achieved by switching to a heatpipe-based CPU cooler (cheapest I could find was DEEPCOOL GAMMAXX 400 from NewEgg). Using 13.6V/4.7A I got -21.6C (hot side 30.8C). Remember, both heatsinks have to have their fans running at full speed to achieve decent results. For all these tests, ambient temp was 25.5C. Secret was using proper thermal compound and lots of clamping pressure (heat transfer is proportional to clamping pressure, TEC manufacturers recommend 25-80 PSI), and lapping heatsink interface to reduce surface roughness and achieve proper flatness.
You legend. Very few people leave out all the rubbish information and provide a great short tutorial ,like you have done . Love it. Thanks. Gonna give this one a shot. You've explained it so nicely that I feel confident , . You could teach primary school kids. That's about my level of intelligence I rekon. Cheers cobber
these peltiers are a fantastic thing for cooling in a small space where you cant use a compressor style design, but remember they are the most inefficient way known to man...so if you have power to waste in order to cool, fine, but if your in a camper van without the engine running etc, your battery's dead in no time, and you will need someone to jump you van off, ask how we know...50-60w of dc drain for about 25w-30w of cooling is average, but as said, in a small space, brilliant
lez briddon They're not "the most inefficient" otherwise they wouldn't be so common. Still, I don't know any other method of using electricity to cool something (below room temperature) that isn't Peltier or Adiabatic.
GoogleMinus your comparison is illogical. while incandescent bulbs were around 5% efficient there low cost outweighed the disadvantages and the lower cost of electricity 25 years ago made it less of an issue. add on to that the modern CFL was not reliable there was no alternative to incandescent. peltiers are cheap to buy as a component for less than 10$ but to compete as a real refrigerator you would need around 6 and a huge power supply against a ready built refrigerator of less than 100$ and about 60w of current draw. peltiers generally suck unless you have no space.
lez briddon His comparison is fine, since there's no substitute for Peltier modules right now (unless someone miniaturized the Adiabatic mechanism of fridges)
ifOnly, there is another technology called magnetocaloric cooling. These devices do have moving parts, but they do not have compressors for high pressure gas refrigerants. They have a small pump for circulating a heat exchange fluid (salt water, I think). A motor is also used to spin a special metal alloy in a magnetic field. The claim is that this technology is 35% more efficient than gas compressor based refrigeration. I do not believe this claim at face value; however, even if it were slightly less efficient this technology offers a lot of advantages to be interesting. I don't know if the technology is also priced competitive to traditional refrigerators. It looks like it shouldn't cost any more. The metal alloy used is blended from cheap base metals, so hopefully this technology will be inexpensive.
first off thank you, but i noticed you added a heat sink on the cold side too. i own a minifridge that i believe works on the same modules as the one you build but it never had a heat sink on the cold side. I'm going to add one as the fridge always has under performed in my opinion. and i believe if the cold side had a heat sink it would perform great. without a heat sink the cold side would always just freeze over while the rest of the fridge was only slightly cooler. thank you again and if i notice a improvement i will leave a response.
the video is called "how to make a mini freezer" but basically you only show us how to cut things. we know how to cut things to specific shapes, what ISN'T clear is the wiring. without that information, this is not a video on how to build this device. i've purchased the pwm controller but i, as well as many others in the comments here can't tell how you're connecting the wires. your only commented response was "you'll figure it out" isn't it best not to connect things randomly? please just explain where the wires go. it's only 4 connectors, would it really be that hard to leave a comment or to put in the description where the wires connect to? did you run the peltier wires down the same tube as the heat sink fan and attach them together?

add a fan inside, ad you'll get you drink cold way faster and maybe if you will control temperature of cold radiator around 1°C your radiator won't freeze and loose conductivity. Also a nice idea to put power adapter next to outter radiator so there will be a smooth look and electronics will be with some air flow.
Since I'm not an electro guy... It'll be nice if u can answer my 2 questions... 1. How to put fan onto heatsink either blow in the wings or to suck from them? 2. How the heavy heatsinks are being held sticked with just thermal paste??
If you make movements on the bottum like turning around, or maybe shaking it. Shall it have influence on the time to cool it. Is it possible you remake this coolbox you have made, whit the bottum moving. And what if you put two peltiers more on each side. Will it become more or quick colder than? Thanks mate love your videos, it helped me a lot.
Great video. Here is a suggestion you may find useful. Next time maybe use a thicker top. You can set the cold side sink deeper in the foam to allow for a thicker top as I think that might allow for colder temps or possible quicker temps. Another thing to try is a different foam board, I forget what it's called but it is typically Blue or Pink and is very dense. You may want to consider using it for the Top since it's so dense and sturdy. Anything thing you could try is maybe carving a V Shaped tongue and groove around the door and box. Granted it's a bit of work but it would keep things aligned and really keep the cold from escaping. Granted your way was fine and these are just possible alternate ways; they may work or they may fail. Cheers...
I tried a few Peltier projects but did not turn out well, PSU issues. Your controller is awesome, could you post a link for it or be more specific about it? It might be a simple controller but I don't work on electronics so it might as well be Rocket Science; just not my area of expertise. I want to get into the Arduino and what not but electronics escapes me; never picked it up as a kid and now that I am over 55 years old not going to pick it up any time soon... LOL... I believe the phrase about teaching an Old Dog a New Trick applies... LOL... Cheers...

love it! you could also add a small fan inside the freezer to speed up cooling for the whole inside region. sinking the magnets a bit deeper into their holes would also increase the efficiency of the system.
Xfiles98 not really, the bigger the temperature difference between the cold and warm, the faster the temp in the drink will change.
The best would be to have a copper bottom linked to the cold element, this would cool the drink much faster cause it would be in contact with a cold surface... he could just bend a copper or aluminium sheet in U shape with enough space inside it for the can and then connect the peltier directly to it.
Many ways to improve this design but it remains a good basis.
Kadum the best would be 3D-printed diamond that molds perfectly to the side of the can. A little on the pricey side tho...
Isn't it cheaper to buy one ready made than buy all the components separately?
Obviously, yes, but were you searching for a video on how to build a freezer from parts cheaper than a ready-made one? Nothing in the title or description should have mislead you to conclude that was the point of this video.

Could you combine this idea with your instant drink chiller to cool down the water instead of using ice?
My exact thoughts, because you wont get ice easily on a beach.
Very nice . I would add an internal fan as well + you should use thermal greas . both will make it much more efficient . thanks for sharing .
Back in the 80's I bought one of those from Sears that cooled or heated depending how you plugged it in. It didn't do good either way, and killed a car battery. You could drive down the highway with it on and when I parked somewhere and turned the car off I always had to get someone to jump start the battery.
Maybe the newer ones are made better.
Wow I was surprised when I saw the black heat sink freeze up. That looks very effective.
maybe a good idea would be to add a thermostat, so the freezer shuts of when its cold enough, and strats back up when its to hot. that will save you a lot of power. and also, does the fan make a lot of noice? nice project man!

That much aerogel would cost a few thousand dollars so I don't think anyone would be willing to pay that much.

Simple yet wonderful, the door should also be coated with silicon to prevent leaking
Apply aluminum foil on inside surface it will prevent leakage more
Amazingly useful. Can't wait to make this.
since air is a very bad conductor of temperature, you should use a second internal fan inside the box !
That goes both ways. With moving the air, you also decrease the effectiveness of the insulation since you increase the thermal transfer of all surfaces. It's best to take advantage of the natural convection, warm air will always accumulate at the top, be cooled and fall to the bottom.

Im sorry to say but. You should Not seal the electrical in a box as you did. There is parts that need cooling as well

wow i didn't know ice could faze thru Aluminium and plastic O.o it must of been able to tape into the speed force.
Not the aluminum but it actually can move through the plastic given enough time
Definitely learned something new with this. Thank you!!
Why did the drink moved in your freezer? Look at 5:50 and 5:54. It moved to the right?

Nice work I’m going to do this! 😊
these peltiers are a fantastic thing for cooling in a small space where you cant use a compressor style design, but remember they are the most inefficient way known to man...so if you have power to waste in order to cool, fine, but if your in a camper van without the engine running etc, your battery's dead in no time, and you will need someone to jump you van off, ask how we know...50-60w of dc drain for about 25w-30w of cooling is average, but as said, in a small space, brilliant
lez briddon They're not "the most inefficient" otherwise they wouldn't be so common. Still, I don't know any other method of using electricity to cool something (below room temperature) that isn't Peltier or Adiabatic.
Just because something is common doesn't mean it's efficient (incandescent bulbs). Maybe it is more common because it is convenient and long lasting?
GoogleMinus your comparison is illogical. while incandescent bulbs were around 5% efficient there low cost outweighed the disadvantages and the lower cost of electricity 25 years ago made it less of an issue. add on to that the modern CFL was not reliable there was no alternative to incandescent.
peltiers are cheap to buy as a component for less than 10$ but to compete as a real refrigerator you would need around 6 and a huge power supply against a ready built refrigerator of less than 100$ and about 60w of current draw. peltiers generally suck unless you have no space.
lez briddon His comparison is fine, since there's no substitute for Peltier modules right now (unless someone miniaturized the Adiabatic mechanism of fridges)
ifOnly, there is another technology called magnetocaloric cooling. These devices do have moving parts, but they do not have compressors for high pressure gas refrigerants. They have a small pump for circulating a heat exchange fluid (salt water, I think). A motor is also used to spin a special metal alloy in a magnetic field. The claim is that this technology is 35% more efficient than gas compressor based refrigeration. I do not believe this claim at face value; however, even if it were slightly less efficient this technology offers a lot of advantages to be interesting. I don't know if the technology is also priced competitive to traditional refrigerators. It looks like it shouldn't cost any more. The metal alloy used is blended from cheap base metals, so hopefully this technology will be inexpensive.
first off thank you, but i noticed you added a heat sink on the cold side too. i own a minifridge that i believe works on the same modules as the one you build but it never had a heat sink on the cold side. I'm going to add one as the fridge always has under performed in my opinion. and i believe if the cold side had a heat sink it would perform great. without a heat sink the cold side would always just freeze over while the rest of the fridge was only slightly cooler. thank you again and if i notice a improvement i will leave a response.
A RUclips names greatscott did this already like 2 years ago.
Very nice!
How about an internal blower fan circulating the cold air around the can?
Bet u could drop drink temps much quicker.
the video is called "how to make a mini freezer" but basically you only show us how to cut things. we know how to cut things to specific shapes, what ISN'T clear is the wiring. without that information, this is not a video on how to build this device.
i've purchased the pwm controller but i, as well as many others in the comments here can't tell how you're connecting the wires. your only commented response was "you'll figure it out"
isn't it best not to connect things randomly? please just explain where the wires go. it's only 4 connectors, would it really be that hard to leave a comment or to put in the description where the wires connect to?
did you run the peltier wires down the same tube as the heat sink fan and attach them together?
Maybe add a tiny fan to the cold side to circulate air on the heatsink more effectively and it would be absolutely great.
In video you shown that, Supply to Fan is via PWM controller but my question is that for peltier module how you give supply??
She’s a beautiful lady 💍 ❤️
Nice build! However, I bought mine assembled. Sure I might have paid more, but with my thumbs in the middle of my hands, what can I do?
HOLA SOY TU FAN ERES MUY INGENIOSO BIEN HECHO SIGO TUS VIDEOS ADEMAS DE DIVERTIDOS Y NO ABURRIDOS. TE FELICITO, SOY INGENIERO EN ELECTRONICA. VIVO EN GUADALAJARA JALISCO MEXICO. SALUDOS Y GRACIAS.
Nice!
put a fan on the little heatsink too helps cool faster
add a fan inside, ad you'll get you drink cold way faster and maybe if you will control temperature of cold radiator around 1°C your radiator won't freeze and loose conductivity. Also a nice idea to put power adapter next to outter radiator so there will be a smooth look and electronics will be with some air flow.
Very cool idea
Awesome!
U r d boss...with so precision... !!!
Nice, new PC project!
nice video. how about you put a fan on the inside too for the air to rotate
perfect for insulin transporrtation
Since I'm not an electro guy... It'll be nice if u can answer my 2 questions...
1. How to put fan onto heatsink either blow in the wings or to suck from them?
2. How the heavy heatsinks are being held sticked with just thermal paste??
Hello, good work, health for your labor
Excellent video
very nice..thumbs up👍👍👍
If someone was going to try and make a frozen slushy machine using these items, how would I extend the freezing end into liduid and would it work?
first im impressed with the video production then the narrator is good
Tal ves no entiendas español,pero los inventos que haces son geniales,te felicito!!!
cool, would like to see you make one that uses refrigerant rather than a peltier cooler.
Big thumbs up, dude! 👍👍👍
genio !!!! saludos desde BUENOS AIRES ARGENTINA !!!
If you make movements on the bottum like turning around, or maybe shaking it. Shall it have influence on the time to cool it. Is it possible you remake this coolbox you have made, whit the bottum moving.
And what if you put two peltiers more on each side. Will it become more or quick colder than? Thanks mate love your videos, it helped me a lot.
Nice, a small fan on the cold side would be useful
Great video.
Here is a suggestion you may find useful. Next time maybe use a thicker top. You can set the cold side sink deeper in the foam to allow for a thicker top as I think that might allow for colder temps or possible quicker temps.
Another thing to try is a different foam board, I forget what it's called but it is typically Blue or Pink and is very dense. You may want to consider using it for the Top since it's so dense and sturdy.
Anything thing you could try is maybe carving a V Shaped tongue and groove around the door and box. Granted it's a bit of work but it would keep things aligned and really keep the cold from escaping.
Granted your way was fine and these are just possible alternate ways; they may work or they may fail. Cheers...
Thanks for your detailed comment, we are all here to learn :D
I tried a few Peltier projects but did not turn out well, PSU issues. Your controller is awesome, could you post a link for it or be more specific about it?
It might be a simple controller but I don't work on electronics so it might as well be Rocket Science; just not my area of expertise. I want to get into the Arduino and what not but electronics escapes me; never picked it up as a kid and now that I am over 55 years old not going to pick it up any time soon... LOL... I believe the phrase about teaching an Old Dog a New Trick applies... LOL... Cheers...
Could you post a separate video where you undo do the wooden box and show us the interior wiring
very nice project.thanks pro
WOW dude, you make some awesome stuff and videos. Some of your videos you are just putting stuff together but many of the others you do a great job at explaining the components and what one needs to do to put it together. Keep up the Awesome work. You are a absolute joy to watch.love your videos.
It's great to see young women involved in tech
