In 1834 a French physicist named Jean Charles Athanase Peltier discovered that passing a current through two dissimilar metals could create either an increase or decrease in temperature at the junction of the two metals.
This phenomenon is known as the Peltier Effect.
Modern Peltier Coolers are semiconductor devices, While they are not as efficient as conventional air conditioning they still have many practical uses.
Peltier coolers are used to cool down hot CPU and GPU chips in high-end computers, to power portable coolers, to cool the water in water dispensers, and even to reduce heat in spacecraft.
Today we will do some experiments with the TEC1-12706, a very common and very inexpensive Peltier cooler module. It’s easy to use, and a lot of fun to play with!
We will see how the device works and learn about the Peltier Effect and the Seebeck Effect, the complementary effect that can convert heat into electricity. We will even make some ice on the workbench!
We’ll also test a popular Peltier Cooling assembly that you can get on eBay and use to build a personal cooler.

Awesome tutor!! 👍👍 you're a proof that everything can be understood with no brain-pain with the right fundamentals explained and building the right words upon them!
Great demonstration. I have the same Micronta multimeter that I bought from Radio Shack when I was a teenager back in the '70s - yours is a lot less beat up then mine after many years of use. We had a water cooler that used a pair of Peltiers to cool the water. It worked quite well and was silent vs. the water coolers that used a compressor.
Hi, I really like your vids, about four yrs plus I purchased; I don't remember how many peltier tiles/ devices.
Just watched your vid and it reminded me, now I'll have to search for them and to try what I wanted to do back then.
Thanks for reminding me.
Hope you and all your viewers and subscribers have a great Christmas.
i have been looking for articles like this about peltier coolers and he explained it so clear... thank you sir.
Just got a pair of these, now I can also make some use of them, and all the heatsinks I have lying around... Thank You, Good Job Sir. Much appreciated.
„Cool“ episode 👍
Peltier Coolers are also used in dedicated astrophotography cameras to cool the camera-chip and reduce noise in the images.
Very good video. I enjoyed watching and learned many things in 20 minutes. I like too, the open and close music. I watched while sipping coffee in my DroneBot Mug.
Oh what fun!
Thanks for another great video.
Hi, honestly, I would want to have a professor like you during my Bachelor studies. I am more than sure, I would have much better marks and understanding of engineering.
and better career
Society is past the need for professors gentleman like this provide better experiences without the unnecessary affluence, because in the end people only care about what you can and can't do.
Very well explained and demonstrated. Thank you!!
Thank You, for sharing your information, I truly enjoyed it all JV.
I have just discovered your channel. I think it's great. I'll rewatch this with my nephew, and do the same at home, see if I can spark the engineering bug in him. Cheers!
Researching the Blaux portable AC brought me here, took me a while to find a website to finally tell me the science behind it and this looked like the best explanation of it and I'm really glad I found my way here; subscribed and am looking forward to learning from this channel!
Very simple yet to the point. Nice one man
Thank you for sharing! Amazing as always!!
loved the vid, I had used two of the same peltier modules for a project 10 or so years ago, seemed real inefficient to cool beer from a keg through the system I made up, fine until you invite a friend or two. Princess auto had them in their surplus section at that time with absolutely no instructions or info. Eventually found out how much smoke it actually holds, I would not recommend 24volts.
Best tutor in youtube on thermoelectric ! 👍
Another excellent idea, thanks. Bill
Thanks
i had looked up like 5 videos of people complaning about how this works and i didnt understant.
Then i saw your video and i
learned alot Thanks :D
You are super awesome man ! Welcome to the workshop !
Muito obrigado. Excelente vídeo.
It is amazing what a person with knowledge can do using the right words and equipment.
Love your video.
I bet getting that bench power was a big day for him!
Great presentation! This is very informative and concise. Cheers!
Excellent explanation and demonstration and to the point. Thank you.
A really good lesson. Explanation is easy to follow.
Thanks for the video I learned something new today.
Thank you for this amazing video
Awesome class, thank you!
Good vid, thank you.
I made a shunt-type opportunity (solar/wind) charge controller for yachts using a set of water-cooled, current regulated peltier devices. Having a large supply of water, the efficiency increase over the typical air-cooled applications was incredible, even accounting for the small pump (which also ran in proportion to the hot side temps). I say 'set of', as these are current devices, not voltage devices. When I would start to exceed the maximum efficient current, then I'd switch another peltier device into circuit to keep the battery within my desired charge parameters.
The delta-T runs around 90*C (hot to cold), it's the Q that they suffer from. Most commercial applications use a forced air heat sink, my experiments showed that they were a much more practical device when water cooled (the colder the hot side, the colder the cold side, if that makes any sense).
Terrific video! I am looking to cool a small outdoor fish tank and this gives me some thoughts on how to go about it. Thanks for the work on it. I learned plenty.
Thank You For Helping Others LEARN!
Thank you that was extremely helpful
Thanks again, nice video
I LEARNT A LOT !! THANKS FOR THE VIDEO !
Very good video. I've been aware of the effect but not the module for experimenting with it.
I just wanted to say thank you your effort is noticed and I thank you for feeding my curiosity
great presentation sir, you cleared all my doubt, god bless u
Excellent explanation sir!
I intend to do better placing comments. but this is my first comment on a post....If I could give you an A + I think you give the best tutorials. Others do not give enough details that leaves a person searching for more info. Keep up the good work. Thanks a lot.
Great video! Subscribed.
thank you
Awesome again.
Thanks professor!
excellent! Thanks a lot.
awesome video!!
The voltage generation in a peltier device relies on temperature differential between the two sides. Keep the cool side cool, and heat the other side, and you get more voltage. I've never measured the current capabilities, but I don't think it's very much. Although, as stated earlier, they are used to run a fan on a stove.
excellent
Very helpful video. I like it
No one seems to be mentioning this, but this tech was used in space also for a long time. RTG (Radioisotope Thermoelectric Generators) were used on probes, satellites, and rovers. Basically uses the heat from a radioactive source to make power.
great videos.
Thanks 🙏
amazing
During the video (I tried to be quiet) I checked out the prices of Peltier devices and they are CHEAP - cost effective. So thanks for the info, I can think of all sorts of uses - both hot and cold plus electricity in and out. Nice video.
Thank you for sharing...
but inefficient. power is not free.
Cheap is relative. Cheapest I've found for the exact same device is 3,27€ (about 3,50$ at time of typing) but this does not include the ones I've found from chinese (long delivery time) suppliers. My experience with them is that the published specifications just aren't accurate. At +-4$/piece geneeating about 2-3 watts of power with 80-100°C of temperature differential AND decent heat sinking, I'm not convinced this has any practical or economical advantage for general home or even industrial power generation. As he clearly mentioned, it's probably only interesting in very specific applications.
Amazing devices
I am thinking about building an evaporative cooler, which also uses a thermoelectric plate to support evaporative cooling. Thanks for your help!
Excellent video.
Thank you!
🎉🎉👍very very informative
Very interesting
I have 2 Ecofan AirMax fans that are Peltier effect powered that sit on top of my wood burner. They have a small motor that drives an 8 in fan blade that circulates warm air from the wood burner. Works good. Backup in case power goes out in the winter. Made in Canada.
Your workshop is very tidy good sir..
Loved the video so much, thanks for the midnight science lesson :D
I'm here because I saw some guy cool his Steam Deck using this. Looked up what the effect is. Cool stuff!
Perhaps a solar-powered combination beer cooler and soup warmer for the next camping trip?
My Lincoln MKZ ventilated seats use 2 Peltier devices per seat it was a happy surprise as I always had heated seats never cooled. And let me tell you it gets over 100 degrees F with the fan cycling on and off blowing hot air at my backside
Neat.
I would like to see a pop can cooler/oven.
I can see it now. A can of your favourite beverage getting cold and just below the cooler a mini oven heater up you lunch. Great little gadget for a office workers
My dehumidifier brought me here, it runs on a Peltier device and that interested me. Works really well too.
G R E A T...just GREAT!!!
Very very cool! (sorry)... I am gonna play with this as a cooler or heater for the boat.. dang what fun!.. carry on and thanks for this one Bill.. new things to play with... outstanding! be safe..
LOL, somebody had to be the first to say it! Thanks Tink!
@@Dronebotworkshop So true.. and it always seems to be me.. thanks again Bill.. that video lite (is that the right word?) a fire in my imagination..
Thank you. I enjoyed the video. I am searching for a good MSc project on thermal engineering, maybe I will try a refrigerator using peltier device
Cool for a while and hot for the rest of the time.
thats what heat sinks are for dude
exellent
Peltier devices are widely used to generate electricity in stove fans.
Stove fans actually use seebeck generators so TEG's not TEC's
@@YorkyPudinz What is the difference? Do they have a different nomenclature?
a temp reading of the hot side exhaust on that kit would have been very important so that people would understand how bad efficiency is. Also the amps since i didnt hear the watts of that TEC...
now I know where I could find it thanks
Amazing! This peltier effect principle may well be the future of refrigeration and airconditiong. Look at LED's, they were formerly used as indicators or sensors only but now most lighting use this technology at cheaper cost of energy.
Peltier effect can someday produce cooling effect cheaper than a compressor can do. If only liquid nitrogen or CO2 is easy to come by.
actually its been around for many many years but due to TERRIBLE efficiency they are being replaced...
imagine that to cool a room you would need well over a kilowatt of peltiers and a gigantic power supply. The peltier in the vid is probably a 92watt@ 12v =7.6 amps
@@ihater3tards you need at least 3,5kw COOLING capacity for an average 30m2 room.
An A/C uses about 1kw for that.
Peltier would use 35kw for the same cooling capacity.
So dont even think about an air conditioning using anything peltier related.
Do you do research before leaving comments? I have some exotic sand to sell you. It's special.
@@op8995 Most people don't research before leaving a RUclips comment no lol, If you don't have anything nice to say and all that.
This was pretty cool. I have a project I want to put outside for long term and living in Arizona, US this could be useful. However what is the current draw on the device?
Hi, thanks for the video.
Can you please tell me what was the temperature value, at which 1.5V was obtained?
Just a question, just like you used a heater on one side and showed us how electricity is generated, I'm sure it works with cooling that way as well, right? Wonderful Video and Explanation! Thanks.
Hot/Cold Most of the Peltier modules I've used are as follows. Leads Facing you. Positive lead (Red Wire) on right = Cold side Up. Just a little FYI
Awesome video. I have a question that hopefully you may be able to answer. I have a couple of cooling units that came out of a laboratory pipetting machine. The Peltier devices are labeled as “TZ6B1203-10” and “TZ581505-02”. For the life of me, I cannot find any information on them. Any thoughts? Thank you.
I don't know how much of a factor it is here, but you really don't want to run these at full voltage. They will tolerate 12 volts, but they have terrible efficiency at higher currents (and they also hate PWM, or even just being turned on and off too frequently), so controlling them is not entirely trivial.
A really cool episode....
You sly devil
This could have great applications when it comes to personal body temperature control
My thought exactly. The last time I worked with these was early 90s. My recollection was they were ceramic and quite expensive then. The video could have gone much farther -efficiency, what's better....
Educationally this is a great device to put in students hands for the concept of entropy.
It would be really terrible at that.
You would need a huge battery and an even larger heat sink
Maybe in space suits? But as mentioned, what about heat sinking?
Great video! Thanks! Do you have a website where I can buy these?
can i call down my workshop, in Australia it gets up to well over 48C in the summer, it will be 38 tomorrow.
Whoa...
I'd never heard of the "Peltier Effect". . .
I googled it from my cheap camping cooler manual, and ended up here.
Thought the cooler was a gimmick, as last summer it didn't seem to get very cold.
So this summer I found/read the manual. . . . .
This would work well on Macbooks, to transfer heat away when they go into "meltdown" mode.
Nice looking workshop
It would be nice to use this to make a still for distilled water. Evaporate the water on one side and condense it on the other.
It would not be necessary to generate steam, just evaporate the water in a closed system.
I suspect it would not be very efficient, taking a long time to produce any output.
it means can be use for room airconditioning or a heater
thanks for the video!
can you do and experiment and see what the maximum current and voltage you can get with temperature high temperature differential. like the thermal electric power generators on RUclips.
Until a few days ago, I didn't know about thermoelectric cooling. I just couldn't believe cooling can be achieved from current flow. I though it always caused heat.
You mentioned you could series modules for heat capture but there are better ways of heat capture. In your opinion, what’s the most efficient heat capture method? Say to charge a battery bank from a small camp fire as an example.
Astrophotography cameras all have Peltiers to cool the ccd chip to around 50 Celsius below ambient.
That sounds like an excelllent use for them. Things have come a long way since I had my 6-inch reflector (Edmund Scientific) in the early 70's!
Great demo! I've played with them years ago and have a small Coleman cooler using the chip. The inefficiency is what keeps them out of mainstream applications. More energy is converted to heat than to cooling. I think they have a limit of Delta-T. I think around 35º? So, say for one of those portable coolers you plug into a cig lighter, if the ambient temperature is like 90, the contents won't cool much below 55-60ºF.
Pu-238, with added "alchemy" of nuclear plasma physics
Can a peltier device be powered on for 100 consecutive hours?
I used to have to soft solder a pyramid of these to a copper part . It was one of the most tedious things I have ever done.
Still wondering about stacking these devices? How cold can they go?
Small note: they aren't really very popular at all in pcs. Heat pipe based air coolers are most popular and even water cooling is far more popular. Cool tech though.
Yup: they were, for a brief time, in the 90s.
When PC parts didn't heat that much like they do nowadays.
TEC = Thermo-Electric-Cooler = Material-Combination chosen for Cooling. Therefore it has a low max. Temp. of the Materials.
TEG = Thermo-Electric-Generator = Material-Combination chosen for Generating Electricity. Therefore it has a high max. Temp. of the Materials.
Most important is a high (sustained) Delta-Temperature of the Surfaces on the TEC/TEG.
The most practical application I've seen is those heat-powered fans on wood stoves. Seems like you should be able to rig something up that you could use in camp to charge all your batteries and/or light the place up at night, if you wanted. I think a camp-stove manufacture has integrated TEG cells into charging electronic devices. About the size of a coffee pot. Has computer fans as blowers that re-charge themselves, too.
