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!

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.

I'm here because I saw some guy cool his Steam Deck using this. Looked up what the effect is. Cool stuff!

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.

„Cool“ episode 👍 Peltier Coolers are also used in dedicated astrophotography cameras to cool the camera-chip and reduce noise in the images.

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.

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.

Very simple yet to the point. Nice one man

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.

Thank You For Helping Others LEARN!

You are super awesome man ! Welcome to the workshop !

Excellent explanation and demonstration and to the point. Thank you.

Best tutor in youtube on thermoelectric ! 👍

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 well explained and demonstrated. Thank you!!

A really good lesson. Explanation is easy to follow.

It is amazing what a person with knowledge can do using the right words and equipment. Love your video.

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!

Thank you for sharing! Amazing as always!!

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).

Another excellent idea, thanks. Bill

Great presentation! This is very informative and concise. Cheers!

Thank You, for sharing your information, I truly enjoyed it all JV.

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

Awesome class, thank you!

I just wanted to say thank you your effort is noticed and I thank you for feeding my curiosity

Excellent explanation sir!

Thank you that was extremely helpful

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.

Very good video. I've been aware of the effect but not the module for experimenting with it.

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.

Thank you for this amazing video

Thanks again, nice video

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

Thanks for the video I learned something new today.

My dehumidifier brought me here, it runs on a Peltier device and that interested me. Works really well too.

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.

I LEARNT A LOT !! THANKS FOR THE VIDEO !

Perhaps a solar-powered combination beer cooler and soup warmer for the next camping trip?

great presentation sir, you cleared all my doubt, god bless u

excellent! Thanks a lot.

Great video! Subscribed.

Muito obrigado. Excelente vídeo.

Awesome again.

Thanks professor!

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.

I am thinking about building an evaporative cooler, which also uses a thermoelectric plate to support evaporative cooling. Thanks for your help!

Your workshop is very tidy good sir..

Very helpful video. I like it

excellent

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.

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

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.

Very interesting

🎉🎉👍very very informative

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.

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?

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

now I know where I could find it thanks

Hi, thanks for the video. Can you please tell me what was the temperature value, at which 1.5V was obtained?

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.

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..

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

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.

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.

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.

Do you think using a peltier or two to heat / cool a small climate controlled chamber 2ft^3 would be sufficient?

Great video! Thanks! Do you have a website where I can buy these?

If we have the same hot plate (50 degrees), the same heat sink, but different thermoelectric modules (e.g. TEC1-12702, TEC1-12706, or TEC1-12710), which one produces more power? Can you please elaborate this as I'm new to this area :)

I am trying to bring the temperature of a 10 inch squared box surrounded by a 5 inches of styrofoam down to 20- with a single pelter thru a small hole cut out of the back of this box. What wattage pelter do I need and can it be air cooled or would water work better? thanks

could it be used to cool a computer case? modern cpu are now at 105 watts form the 65 i was just wondering if it could be used to cool a mid tower case of like 1.5 feet? the condensation is a concern?

Hi you talked about generating power from heat saying that this is inafishant. What it the best way to get power from heat?

Thank you. Why using fan temp stays 17 deg C? I have one with heatsink and fan on both sides with min temp 13deg c only??

Still wondering about stacking these devices? How cold can they go?

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.

Is it possible to turn on and off 1 side of the peltier module? Like can I keep the cool side on but turn off the hot side?

exellent

How can I select to get those peltier from junk please ? 👍👍👍 Thanks very much for your information s.

Peltier module work on 12 v Pulsating dc supply? It will affect it's life and performance?

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.

One simple question about the Peltier . Can I put it directly to a 12v battery or should I need to drop the Amperage to a certain level ? Thanks in advance for the answer

DQ (dumb question) can you use different size identical conductors size 8 size 14 cu wire?

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.
