Peltier Soda Cooler Machine - DIY Drink Dispenser

Subscribe to my channel for more awesome projects: / rclifeonsimon
By using three powerful 100W peltier (thermoelectric cooler) modules, with giant heat sinks and water blocks, I was able to chill a glass of Coca Cola all the way down to 7°C in matter of 10 seconds. Oh well, I did have to wait 10 minutes for the water blocks to reach -17.5°C before I was able to do it, but I'm still going to count that as a success!

You should install a computer controlled valve on your output. Add a DS18B20 sensor to control the valve on a raspberry pi zero or arduino, maybe a relay depending on valve voltage... Set it up to pump into the cooler, and once the liquid reaches a certain ambient temp - the valve opens to squirt some out. Once the output liquid temp rises because the "fresh from bottle" liquid is flowing through - stop the valve until that cools to a set temperature... You'll always have cool liquid.

[@jimeththemelancollie351]

I'd love to see this done over with some thought given to the flow of heat between the various parts of the cooler. Heat pipes function better with the heat source at the bottom, as they work through the evaporation and condensation of the water inside them, and heat rises. A lot less important but still worth a mention is your fan orientation in other videos. How you have them here is fine, but the orange juice freezer had the fans blowing downwards, essentially working against where the heat "wants" to go.

[@MrChris20912]

Love you're experimental mindset! Thanks for posting this. Hah, especially enjoyed the bottom if the cup view cam at the end! After seeing a few pieltier based cooking projects on KZbin, yours is by far the most minimalist and experimental. There seem to be a handful of people trying interesting cooling alternatives since there's now a cooling/HVAC X-prize compression through 2019-20.

You should add a thermal mass to the heat exchanger block to prevent it from heating by the flow too quickly. Big chunk of copper or iron should be fine. Also, keep in mind that if You leave the liquid inside the block it may be cracked once liquid got frozen.

I think you should try to flip the whole thing upside down so heat will rise up into the cooling system more efficiently and use smaller tubing for the drink. Also a fish tank air pump valve might help dial in the flow rate. Keep on making these videos, they are great work.

[@turbotonic27]

[@geras7556]

Hello, I would like to know what the plates with 2 holes are called (I am not talking about the peltier) is where the water enters and takes it out

[@varma.]

Move the flow control contraption to the exit pipe, that flows into the glass, so that the liquid outflow gets compressed thereby allowing the liquid to stay longer in the cooling chamber.

[@josephcarney5169]

[@davidianmusic4869]

Great work, I’m doing a similar project, this has helped. One suggestion, bleed off some of the air to reallly slow down the flow, and add some sort of mass to the cooler block, that’ll help hold the temperature down when the coke passes through the block.

[@VrishiSpin]

would it still cool down the drink a good amount if i limited the flow more but only had one heatsink and peltier module?

[@gilb6982]

Fun project it is 25 amp at 12 volts so on 220 v it is 1.36 amp and for 10 minutes it use a big < .13 amp > not so expansive for a fun project May be you should turn the unit upside down for better perfo < heatsink block under > because the heat always go up

[@mgut17]

now, where is the more polished version of this?

Slowing down the output even more as well as using copper or metallic piping/tubing could make this thing work really really well. Is worth investigating, I would buy something like that! Good idea

What if you put a potentiometer on the pump? That would slow the flow better i think.

[@PaprikaYT]

You dont do that. Potentiometers are mostly not suited for high currents. You would take a transistor or a mosfet and then controll that with the potentiometer. The mosfet is then controlling the pump

[@jstagzsr]

the way those style cpu coolers work, dont they have to be right side up (or sideways but less effective still) for them to work? aka youre not cooling the hot side as well as you would if you just simply flipped that whole contraption upside down with the waterblock on the bottom and the coolers right side up?

[@JohnyDees]

Why you didnt Put the heatsinks on bouth sides of that Block?

[@ericvauwee4923]

Peltier-Elements or thermoelectric coolers work by "tranporting" the thermal energy ("heat") from one side to the other. To do so, you put current into them, and one side gets hot (the one with the CPU-Cooler) and the other one gets cold (the side with the waterblock). If you put another heatsink on the water block you actually "waste the cold" as there is more thermal mass to cool and the fan even mores more air through it. So to actually improve cooling, you should insulate the cold part, so that the only medium to get cooled is actually the coke passing through.

[@JohnyDees]

Eric Vauwee yeah im not dum of course you put another module in between

[@MrModTwelveFoot]

Right. Heatsink-peltier-waterblock-peltier-heatsink.

[@T5MKINDYOWNER]

I'd think double/triple stacking cooling blocks on top of each other so the soda passes through the block furthest from the peltier then through the block nearest the peltier will help drop the temperature further without adding extra current demand. It will increase the thermal mass the coke has to warm too which can only be positive! Obviously the initial cool down and recovery time will be slower but it will be a cost effective way of improving the efficiency and dropping the final temperature. You could also insulate the cold side to prevent ambient heating though the effects will most likely not be that great, finally flip the system upside down since heat naturally rises which will have a small effect on making the heat sinks more efficient. 'Cool project' though :)

[@bugz000]

was thinking this exact thing, big block of metal on the other side of the waterblocks to add a ton of thermal mass :)

[@nightmareinaction629]

those blocks have lead on them an quite alarming rates of it sent water sample passed through it and came bad with really bad results

[@OZSCQUADS]

did you try clamping the output hose also? that might slow the flow through the cooling block, and thus further cool the coke, right?

[@errolfoster1101]

which would be best limiting flow or slowing pump

[@RickB3n]

From experience I have noticed that heat pipes work better if oriented in the right direction. In this case the heat sinks should be turned upside down

[@internetwantstoknow]

Why not put a glass on top of the coller module and just add coke slowly. It will give better results and keep it cool also

[@VeritaZFFS]

Why not put the bottle into the freezer for 5--10 mins....

[@scrow7752]

​@@Fstop313 Copper? Or something non-toxic that wont react with soda but still conducts heat well. Whatever spreads that frost along the whole length of the tube, it could act like a cold-capacitor of sorts. Even better if the thermoconductive pipe is surrounded by a slightly wider insulating pipe filled with thermal-capacitive fluid/gel.

Instead I got a pre-assembled printer last summer and it's been running flawlessly with zero calibration (beyond the auto-calibration it does before each print) or maintenance. If you're doing it as a hobby, building your own 3D printer can be a great experience, but if you want something that just works, buy one pre-assembled.
