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.

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.

[@Sedokun]

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.

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.

[@dbugman68]

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.

[@sdc9727]

You should grab another bottle, and some more hose, and circulate the coke through the blocks. This should transfer the heat out of the system, and eventually make the coke ice cold. Add a spout to deliver the coke out of the circulatory system. ;)

[@chirinosronaldj]

The idea of choking the fluid was good, even though you should put it at the outlet of fluid instead of at the inlet, that's the reason why thermostats exist and they go in that point of the system. Good job kid.

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

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

I developed a similar controller to control the temperature of ICs between -70 and 180C. i also tried using large heatsinks like yours using heat pipes; I discovered that using this system I could only get down to about -20C on my second stage plate. I'm pretty sure that's because the liquid in the heat pipes has to evaporate; meaning the hot plate gets to a higher temperature, thus the cool plate is at a higher temperature, If you want it to work faster using a standard aluminium heatsink with a couple fans should do the trick.

[@olivierdamiron7279]

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.

[@hanspetervonderfecht7722]

Nice i got an idea to create my own air conditioner thanks to your beatiful brain . Maybe you can make a little labyrinth in the watercooler.

[@TheExplosiveGuy]

Probably a little late, but you've got the whole assembly upside down. Those heat pipes on the heatsink have a liquid inside that needs to be in contact with the heatsink itself, it boils and rises up the tubes to condense on the walls of the upper tube, transferring it's heat to the copper and dripping back down to be boiled off again. The more heat you can pull off those TEC cells, the more cooling power you'll get out of them. And try modulating the voltage of the pump motor to fine tune the flow of liquid, a trickle would be ideal. Also, adding a peice of aluminum bar stock to the water block bonded with thermal paste will increase the amount of liquid you can flow through it before it warms up, and insulate the outside of that as well to decrease losses. Awesome project, I like the idea of cooling on demand versus cooling the entire volume at once. Kinda like an Insta-Hot, but the opposite.

[@kornshadow097]

Two things wrong with this efficiency wise.. One is heat rises so the cold side is being heated up.. Second thing is the way heat pipes work requires the block to be on the bottom otherwise there is no liquid to phase change and it is basically working like a heat sink but not a heat pipe heatsink... Try it again once you know what you're doing. Cool air pump idea though. But I've built much more complex cells for my a/c unit I made. Also power wise if use a 12706, nothing higher as efficiency drops with higher power units.

[@deckmonkey1459]

Heat doesn't rise it travels to cold, that's basic knowledge. If you don't know that, how can you tell him what he's doing wrong? It seems pretty clear you are confused by you talking about phase change. It's a heat sink. The block gets cold, the Coke goes through it. Nothing else.
