Which is the best Peltier module for your project? [test 1]

Hello, my friends!
I received a lot of questions about Peltier modules, especially about the TEC1-12706 type, which is actually the least efficient.
But which is the best one? In this episode I will test a few Peltier modules to find out.
A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.

That was fascinating, many thx for sharing and I’m pleased to see your assistant is still working hard keeping those tricky capacitors off the table 😀👍

[@slavalavi7865]

Not at all😊

[@luifalcon]

Best video about TEC!! Saved me A LOT OF math and guess work!! Thank you sir!!!

[@demoking1422]

Nice video great information without exploding music and wild graphics Thanks !

[@ZenInnovations]

What you're seeing is the effect of joule heating. Basically you were able to manage the hot side of smaller peltiers better because heatsinks were larger in proportion. 06 is not rubbish. It has to be planned & executed properly.

[@RCToys09]

Thank you - it would have been nice to see how warm the large heat sync was getting. Liquid cooling would have significantly improved this test.

[@rudygunawan1530]

@@RCToys09 I guess there's a reason why the manufacturer make different types with different price or costing. I bet it not only related with size but also with quality. Using liquid cooling required more electricity as input. So if using same input give different output then we can conclude which is more efficient.

[@paradiselost9946]

thats it, there was just so much not even considered here, mostly heatsinks... cold side temp means nothing without hot side too. lol, heat blocks dont appreciate frozen water. go all bulgy :) i had to see what it would do with no pump.

[@LiamSirBean]

do you know what the best peltier model is

[@LilyNormand]

Thanks for taking the time to explain to us the difference. I am pretty sure that the 4-5-6 didn't perform as well as the 3, only because it didn't reach the appropriate amp. to perform 100%. On the other hand, to get -20C with only 38 Watts of energy is fantastic! Exactly what I am looking for. Thanks

[@FHDesert]

How do you get it to reach the appropriate amperage? My Peltier chips always run at around 3 amps - far lower than their rated amperage. I have been wondering about this.

[@pauls5745]

yes. each module operates in a different sweet spot. more extensive testing needed

[@kevinthompson49]

​@@FHDesert It does reach the maximum amp. but his cooler is not good enough to remove 72W plus the amount of heat energy from the little cold Radiator. So the hot side gets hotter as it should. That follows that the cold side doesnt get as cold as when he used the 12703

[@cruucruu5584]

thank you for the comparison. i was planning to use one for a power source project. 👍

[@bobelism]

Really good information for feature projects. Thanks for sharing! :D

[@TechOverFlow]

I appreciate your hard work. A very informative and helpful video!

[@kamil004]

Test is very good, but only for this size of radiator. If u get bigger radiator with better cooling , u get better results on more power peltier module. so this test is only for this small radiator on hot side.😊

[@Schrimpieman]

Quite similar as to what I was thinking. Smallest-size peltier (12704) performed "best" compared to the group because of its smallest physical size in proportion to the (heat) radiator. Increasing the cooling capacity (ie: Larger radiator or more fan cooling) in proportion to wattage output needs to be considered to make a fair comparison.

[@kamil004]

@@Schrimpieman yeap, thats right ;)

[@ZenInnovations]

@@Schrimpieman you got it.

[@kennethcoutinho4439]

Awesome comparison, now I know why 12703 cost more than double...

[@zachreyhelmberger894]

Thank you for the test!!! I am trying to make a chilled mirror dewpoint sensor!

[@kamui30]

Finally a comparison review worth watching, hope you can come up with same videos focusing on possible effecient products/model against each other. Keep it Up! Thank you.

[@RCToys09]

Repeat the test and track the temp of the large heat sync. You will find that the large heat sync can't keep up with the heat generated by the larger peltier, and it will be hotter with the 12705 than with the 12703. This explains why the temp was greater at 60 minutes than at 30 minutes - the ambient temp of the heat sync rose. A peltier is designed to create a thermal difference between the hot and cold side of the peltier. The colder the hot side is, the colder the cold side will be. For air cooling, the 12703 is better. With liquid cooling, the 12705 will remove more heat than the 12703.

[@johnbaraiya4268]

Good to know!! Thank you it helpful!!😊🙏🥰🥰

[@ab_ab_c]

Please do another video like this one, but in the next video, apply heat & determine which module produces the most electrical power when you use the optimal heating for each module design. From what I see online, the TEC1-12706 can produce 57W at 50C, which is 1.425W/mm2. That means ~702 of the TEGs could produce 1 kW of power with an input heat of 50C

[@satishkumar-rp7zb]

I have been searching for this info from a long time finally I landed into correct place very useful info abt peltier module if I had watched this video early I would have not buy 12706 module.

[@dangerousdoctrine]

Great video! Just what I was looking for!

[@rickadrian2675]

Thanks for the great video with detailed comparisons. I am making a small (5l) 12v cooler/chiller for my motorcycle trips as I could not find anything remotely suitable. As I am looking to have a compact design within the wall of the cooler, your video has reminded me that I need to allow for condensation dripping off cooled element.

[@T2D.SteveArcs]

Are you planning a cloud chamber Sorin?

[@lorenwright3202]

Great info and not boring at all to those interested in the field and info Thanks for the vid and info will help me for sure

[@Kobe324]

Currently working on making a pretty sick Portable AC using these chips. Alot of design is going into it these chips are amazing especially when used correctly.

[@FHDesert]

I'm doing something similar! But with a pillow. How many are you using, you'd need a lot to make any sort of difference even in a tiny personal fan. And you'd have to vent the heat elsewhere or else the net difference is just heating up the room! I'd be interested in seeing your creation.

[@nedstar7378]

The TEC1-12706 needs a bigger cooler then TEC1-12703, with the correct cooling the 12706 can reach quickly to -18 - 20 Celsius.

[@kushlanravindra5786]

What if u add the bigger cooler to the 03 module?

[@AbereniboyeHarry]

It could reach -40 even

[@TomFuPanda]

I think you ar romanian so Salut! Chiar imi doream în ultimul timp sa realizez un proiect cu aceste module, iar videoclipul tău ma ajutat enorm!Mulțumesc!!

[@slavalavi7865]

It is great for aquarium cooling ! Every new summer temperature are going higher and higher . Thank you

[@liviuconstantin9960]

Cool. Literally. (and... I changed my mind about ordering the 06).

[@kevinthompson49]

Great video, but I have Concerns. Later on, you chose the TEC-12703 because it cools down to the lowest temperature. In the mini-fridge you've build, the Amount of heat the Peltier has to remove is much higher, and the Qc of the 12703 is very low. Dont you think the 12706 does a better job when the amount of heat that has to be removed is quite high?

[@Sorin_DIY]

Thanks! TEC1-12706 may be a little better in a closed box, but it draws more current and it needs a bigger heatsink, so the entire cooler will be bigger, more expensive and will draw more energy. I will make a more detailed Peltier test video soon, with more powerful peltier modules, bigger heatsink and different voltages.

[@kevinthompson49]

@@Sorin_DIY I'll enjoy your new video :) I hope you're maybe cooling a liquid or gas with the different peltier Modules, so that we can see how much heat energy is removed through the TEC's. Looking forward to it :)

[@cevikertan4030]

Thank you very much beatiful video best Science ❤❤❤❤❤❤

[@DSeeKer]

Yes I would like to understand the differences in energy generation also maximum temperature each on can handle

[@pilsnerd420]

3:18 as the condensation forms it changes phase so heat is added to the system. This is the opposite of sweating.

crazy and almost magical technology I was unaware of until lately. I would be curious about this same experiment with numbers on the heat side also

[@tahmidrahman8222]

Thanks bro for this important video😘😘

[@Daus-eu9kw]

This is a very good share, thanks man.

[@hnilom]

The modules have different electrical specs and they're being driven with a fixed voltage, the ideal way of driving a peltier module is using a constant current (CC), as resistance varies with temperature. Idealy the module should be driven within 60-70% of its maximum current to maximize lifespan. The last digit of the modules indicates their maximum current. The TEC1-12703 has a maximum current of 3A and is being driven a little above its maximum current. So, this module is being overdriven. My suggestion would be to compare them using CC at the same percentage of the maximum current of the module being tested.

[@Sorin_DIY]

Thanks for the suggestion. I bought some new Peltier modules and I will test them in a future video.

[@ayahsadam9817]

Beautiful sharing

[@yogeshagarwal3148]

Thanks bro, this was very useful

[@MumujiBirb-d2l]

actually the problem with TECs are the larger current you run them at the more cooling they can do but the more heat they produce so it is quite likely the reason 12706s are underperforming is due to inadequate cooling. It might be more of a fair test to run them at the same current rather than voltage, iirc peltiers are mostly current affected.

[@Sorin_DIY]

Hi, I recently posted another Peltier test video with a better cooler, you can check the results.

[@ilovethynos]

Lots of love ......from India🍃🐣

[@jozefnovak7750]

Super! Thank you very much!

[@AbereniboyeHarry]

You tested the modules on the same heat sink for the hot side!! Tec1 12706 modules require bigger heat sinks to dissipate more more power and so that the hot side doesn't get too hot. It is because the 12706 module has the highest temperature on the hot side that the cold side is lower than the rest peltier modules tend to want to maintain constant temperature difference on a particular electrical power input if the hot side is too hot the cold side will not be cold enough

[@Sorin_DIY]

Hi. I recently made another Peltier test video [test 2], please watch it, because I explained all this.

[@technicalshorif24h]

Thanks for your information🥰 From Bangladesh

[@chuckles1808]

I was planning on making a peltier water cooler, I planted on using some 12706 modules I already had, but I think I'll get some 03 ones instead. Thanks for uploading!

[@spmoorthy2597]

Really good information thanks brother I like it

[@JKnight89]

Amazing! I've thought of upgrading a small mini fridge i have, wanna try fan first then maybe a new module. Thanks!

[@cameraman1234567890]

Moral of this that isn't shown in the video: The Less load you have, the smaller peltier is more efficient always. If you have a heavier load that makes the module stay at a warmer temperature the entire time (Say water cooling something) you want a larger module to pull more heat at a given time. Same thing happens with a Portable cooler fridge. This is why water cooling something on the cold side is alot better of a load than a heat sink most of the time because the water will add it's heat energy to the cold side 25 times faster than air. However sometimes water cooling the hot side is the only water cooling that's needed to get better efficiency out of the correct size module. The Smaller the volume, the smaller your module should be for efficiency. If its 1 Cubic foot of volume however, you'll want about a 10 Amp rated module instead so that the module can remove more heat at a given time. If the module stays cold on the cold side the entire time, your not fully utilizing the cooling capacity of the peltier unit and are just wasting energy. So always test to make sure it's enough power to get to your target temp, and keep going smaller until it's no longer enough cooling capacity then you'll know what is the best current rating for your project.

[@coolmonkey5269]

excelent analysis bro🎉 i am a newbie😢 tryin to build diy air cooler for home which module and amps u suggest and u recomend both sides water cooled or

[@cameraman1234567890]

Thank you, let's talk about your thermal load. How much room in Cubic feet are you trying to cool? A Thermoelectric system on a large scale wouldn't be very efficient. But that's not going to stop me from giving you the numbers your looking for. With a load as large as this, and for the CFM needed, yes its mandatory to have both sides water cooled.@@coolmonkey5269

[@lizandrobelason9713]

Nice, salamat bro

[@adam_bomb2103]

another reason It might do better after 30 minutes than 60 is the ice forming on the cold sidn acting as an inulator, not allowing for thermal transfer

[@MrIC01]

I think there is new update for our mini fridge video 😁😁. Waiting for it.

[@cisarvialpando7412]

That means lower correct consumption is best peltier module

[@sashilemtur6647]

i think you need to supply 12v 6amps for the 12706 module, for its full load to work.

[@paradiselost9946]

it wont draw 6 amps at 12v, it needs 14v or higher.

I built an ice chest air conditioner. At bottom of cooler is ice cold water and a bed of 20lbs of ice Sitting on a wire frame. Just over the ice layer is an internal lid effectively separating the ice chamber from the air intake chamber. 2 radiators ; one is for intake air the other is for the precooled air blower fan. My question requires your expert peltier knowledge. Cam I usea few peltiers to create a mini freezer keep ice colder longer or make circulating water even colder with salt? I'm concerned about cooling the hot side without heating my ice water. Thank you for your channel and all you do to help us

[@KHG_Film]

[@yt678901]

Peltier modules are good for experiments only. To be used in real life, the two sides are too close to each other. Very efficient cooling systems are required on both the sides. Just blowing air on water with a Fan is more efficient, even in humid conditions. I have tried to cool my fish tank water with CPU heatsink and a Peltier device, but the temps almost remained unchanged. Just blowing air with a small 12V fan reduced the temps by 2 to 3 Degrees C.

[@calutzubv]

interesting. In that way, I could say if I heat a Peltier module on the bottom, I could build a refrigerator on the top. This give me some ideas 🤔🤔

5:07 Is there an error? The chart shows the 12703 Takes 3.18AMP but in the background the PSU shows 3.27AMP

[@Sorin_DIY]

Hi. There is no error. the cooling fan also draws 0.09A from the power supply, so the total fan+peltier consumption is 3.27A

[@ShaydTheDragon]

Oh! I gotta recalculate some stuff then! Thank you! I bought 20x of these Peltier modules you posted@@Sorin_DIY

All of there modules are easy to buy. You can order hundreds if not thousands of them easily.

[@alfreny2901]

In the real world the peltier must be testing with a strong load in the cold face using a fan because the Qmax require a low Delta value (Hot face similar TH and cold face with hard load). If you test without load the results can be misleading.

[@stevenA44]

It figures the 06 would be the worst one, but that's all I have. I got 10 or so for like $2 US at a pallet bin store, so I can't complain too much. I've love to know why cats love to knock things off tables and such. LOL Love the kitty.
