Playing with Thermodynamics: Peltier Element Cooling

DIY Electronic Semiconductor Refrigerator Radiator Cooling Equipment on –

TEC1-12706 Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 12V 60W

The Peltier Cooling Unit was kindly provided by Banggood at no cost to me – there were no cash incentives for me to make this video. The small logo “Paid Product Placement” during the first 10 seconds of the video (bottom left of screen) is a mechanism provided by YouTube. However it’s not possible to differentiate between goods supplied free of charge and payments made by a supplier.

Cool Video Literally Julian. LOL. Keep up the great work. Nick.

Chad Hurley says:

This video reminds me of an idea that I had a few years ago… When you get a beer or soda can from the fridge., it always warms up to room temp before you can drink it. Bummer. So having taken apart my “piece of s**t” micro soft tower I learned about peltier chips. So with my infantile grey matter I thouht, why not cool my beer with a peltier element? So I didn’t know any electrical engineers. So I wrote to “Bob Lazar,” alien engineering scientist extraordinaire and he wrote back very quickly, thanks Bob, that my idea had the non-resolvable problem of heat dissipation. So I just said, well he’s the general and I’m the grunt, so he must be right. Now looking at this unit shown in this video, science and engineering is a step closer to my dream of infinitely cold beer.
Can a “peltier” be made into a barrel shape, instead of flat, so that a can could slip inside? I know that the heat is still a problem, but the surface area would be much greater than the little CPU squares, so the cooling side wouldn’t have to be freezing and thus the heat side could be relatively cooler. Maybe cool enough that in use could be grabbed by the, now happy, beer drinker.
So the cat is out of the bag now, so I won’t become Trump rich with my can cooler idea, so anybody with ideas are always welcome. COMMENT !

Those heat pipe type heat sinks work best with the mating face pointing downward as the medium inside the heat pipes vapourises then condenses on the pipe walls, but then requires gravity to return the condensed liquid to the bottom again. Enjoyed the vid though, I have a project that looks very similar to that 😉

Gadget Addict says:

Interesting. I expected it to consume more power to be honest. The sock puppets remind me of techmoan 😀

robviolin1 says:

That unit with the fans and heat sink could be modified to heat and cool a house. You would not need refrigerant air compressor any more.

+Julian Ilett Please be careful saying that a blunt knife is safer. Rarely is a blunt knife safer, since it requires more force to use it, and therefore things become dangerous more suddenly. Always use a sharp knife, and brace yourself to limit movement. An easy way is to hold your forearms tight against your chest and only use the limited motion of your wrist to force a cut.

Mark Shihadeh says:

Beryllium is actually deadly, may want to reconsider the lip test my man 🙂

MrBrymstond says:

I wonder what size area this would cool because we had a power grid issue that killed our power for 3 weeks and everyone had to cook as much food or throw it out, we had a community cookout… =-)

lez briddon says:

great video as always. i made the exact same thing for a coke’n’ sandwich cooler from a scrap heatsink and a ebay peltier 10 years ago, but buying saves time, so well done banggood, bit expensive but its heavy to ship.

MrSaul2fl says:

You are a lot of fun to watch, I have learned from you a lot. Thank you. PS I saw you pointed your phone to translate oriental language on an shipped envelope. Could you give me the name of the App? Thank you

Gary Templemain says:

2.5 magnifying glasses. Getting old Julian, but don’t give up on your You Tube videos. We need you

The Tyttuutface says:

Also, now that I think about it, you could run the peltier at low power to use it as a dehumidifier. Maybe down to just a few degrees C, or ~40 F. That way, you wouldn’t have to cycle the element, which reduces thermal stress.

William Squires says:

And this, my friends, is how you do moisture farming on Tatooine (for those Star Wars fanboys out there :)!)

Henry Sohbatian says:

Can you do a video showing how to use body heat on that TEG, run through a boost converter to light a led or maybe charge a cell phone??

Gary Templemain says:

Beryllium is quite toxic. First signs of poisoning is your hair goes all grey and need 2.50 magnification glasses,,,,,, just joking.

ravish kumar Shrivastava says:

on hot side the heat is transferred from copper tube to the heat sink, my question is pump is not required to flow liquid

Kevin Miedema says:

oh its *just* beryllium and telluride

French Toad says:

You got one cool fan, and two huge fans quite hot. Lucky you !

ali industries says:

is that a hyper 212 evo clone lol

Bartosz Pucilowski says:

I love your channel, I was looking for an answered online if I can control the temperature of the element by controlling IN – V/I and you covered it in the first 20sek of the video 🙂 Thank you very much!

Electronics and More says:

from there website i gathered that depending on polarity is if heat or cold

marlon glodo says:

Hi sir what kind power supply you used? Thank you

JC Channel says:

I’m using a solar powered peltier dehumidifier in my chill tent.

sounduser says:

I thought c was cooler. teg is a thermoelectric generator.

slyplaymike1 says:

best way to test a beer is to stick it to your mouth

John Coops says:

Using IR temperature gun like that, you need to be firing it at a BLACK object so that you have the correct emissivity ratio. Anodised aluminium is only about 0.77 – see – so any temperatures measured by the IR gun are based on 0.95, unless you have emissivity adjustment.

Anvilshock says:

23:05 “Blunt knife is fairly safe” – Quite the opposite. Excessive force needed to get anything cut at all will risk hurting, and hurting badly.

Shambles1980TRealOne says:

you should always connect ground 1st.. its just a simple thing to do so the live has some where to go when you connect it.

asif ahmad says:

can i connect two peltier TEC1-12706 on both side of a water block and run water through it and get chilled water, actually i wanted to bring the temp of my 15 gallon tank below to 6degree celcius.
I have tried with one peltier but the water coming out was not as chilled.

Todd Harrison says:

I love the puppet interjections. HA! 🙂

wayne hart says:

hi is that water drinkable.

Julian Fernandez Barcellona says:

im guessing you watch techmoan right?

Martin Counsell says:

I always TEC= Cooler TEG= generator ie for power generation as the elements have a different temperature rating so will run hotter before anything melts.

MortenBN1988 says:

“Now, the reason for shoving this in your mouth, is because of course your lips are more sensitive than your fingers, so you’re gonna get more of an effect” – All guys can relate. 😀

SinSki says:

Is there a video of how to make/where to buy that bench power supply at 8:58?

Josh Harold says:

Do not stick it in your mouth!

MrBrymstond says:

They have a 15A @12V I wonder if this has enough to cool a good size refrigerator or maybe 2 of these on each side of the freezer area… Years ago I had a idea to cool this processor enough so it wouldn’t throttle and overheat and maybe use a 1A with a dimmer switch to bring the current up or down, but I was worried about water, but the heat coming of this processor should dissipate the moisture.

tradecycles says:

Hi Julie, Can I connect Peltier with my 75Amp solar battery? Would it be completely safe? Please Help.

duncho says:

Nice glasses, are they from TESCO?

Uno says:

Can we run a peltier less than 12 Volts, maybe with a PC supply?
And can we use 2 Peltiers at a time?

Hermann Schaefer says:

Build a cloud chamber!
