2 Questions.. 1) What specifies the "hot" side of the Peltier.. If I reverse the voltage, Idealy I could flip the hold/cold side right?? Also, How well could you control the temperature if you controlled the voltage/current.
1) HOW THE HELL DID THAT ONLY COST YOU 12.50?? Those fans go for as cheap as about $8-10 each, the heat sinks are at least $15 (probably more), and a peltier that size seems to be going for at the cheapest $20-25...
@Joovie88 Nope. The TECs are roughly 12 bucks on Ebay. The heat sinks you can pick up for 99 cents for the time being on Ebay also. Ebay is the place to get all this stuff, but on your side also :) .... they are all going up in price. You just have to get lucky.
this is great! I want to turn my big picnic cooler into a fridge and run it continuously. can I use my rv's deep-cell marine battery to power it thru my lighter and if so, will my battery keep a sufficient charge to do this if it's on a standard battery charger plugged into the wall? Don't ask why I want to do it this way, it's too complicated. If not, what kind of battery can I use? I've read that you have to use dc power, never ac.
@Zaharkl Yea, but you'd have to mount it on top of a huge-ass passive heatsink and clamp it down pretty thoroughly, or else the whole thing will just overheat and explode.
Yes and no, yes if it is regulated, and no if it isn't. The peltier coolers used for CPU coolers are regulated, if the cooler was on all the time there could be a potential buildup of condensation on the processor that could easily short something out.
You know what they should do with thse things. Is Install huge ones on the roof of Houses and then The part thats inside will have a fan on it, Then when its hot out side It will run a Fan as well Get frosty cold on the other side. Then in the winter it will be frosty cold outside and it will keep it warm on the inside and will run the Fan to blow the heat off. Pretty Much Same thing just reversed. And it would be considered "Green Solar Energy"
@Learnthethingsido The problem with your pipe-dream is that peltiers, which are basically just dozens of semiconductor cells sandwiched between two different metal plates, consume an ass-tone more energy than they produce, something that is unfortunately inherent to any non-superconductive materials but even more true when it comes to semiconductors
So the potential for "green energy" is null
Also, you can't just reverse the effect by reversing the current-flow so you'd have to flip them over
Your reading comprehension sucks dude. What he is saying is that if you decrease the amps you have to raise the volts to get the same watts and vice versa.
@gamewizard If you raise the volts you'll raise tha amps at the same time you complete moron , Theres nothing wrong with my comprehension ....You don't understand the relationship between volts and amps and neither does he and thats the problem
Watts= volts x amps. Look it up sometime. If you lower one then you have to raise the other in order to get the same amount of watts. YOU look it up moron.
@gamewizard The problem you have is that you've looked up a formulas and don't actually understand how it works.. if you lower the volts you lower the amps at the same time!! you can't adjust them independantly.
The way you raise the amps is by applying more volts...
Let me make it simple for you. If you want to output 100W, there is not just one way to do it. Since Watts = volts x amps, then you can plug in any divisor of 100 into the equation and get 100W. 1 volt x 100 amps =100W, 2 Volts x 50 amps= 100W, 4 volts x 25 amps =100W, etc. If you raise the volts, you MUST lower the amps or you won't get 100W anymore. You can't raise the volts to 4 and leave the amps at 50 or 100 because then you'll be putting out more than 100W. Understand now?
@gamewizard Let me ask you something, If you have a peltier chip and a set amount of voltage, how the heck do you think you're going to raise the amps without raising the voltage to do so..be interested in how you'll achieve this feat
You don't have a set amount of voltage. An ATX powersupply can be modified to deliver many different currents. You have 12V coming off an ATX PS right? You also have 5v, 3.3V etc, and if you know how to modify a power supply you can make up whatever volts x amps combination that you need.
@gamewizard I know you don't have a set amount of voltage, but you were talking about independantly adjusting the current... you cannot do that with out adjusting the voltage, you seem to think that you can, so I asked you... if the voltage is set how do you adjust the current? . You do not understand how electricity works thats painfully obviousfrom your previous reply, you cannot have a 2v supply as you've stated and somehow increase the current to get the same watts..it doesnt work lke that
@gamewizard You said this in a previous post "Watts= volts x amps. Look it up sometime. If you lower one then you have to raise the other in order to get the same amount of watts. YOU look it up moron."
What you fail to understand is that if you lower the volts you also lower the amps and the watts all at the same time, a 100watt lightbulb for instance is only 100 watts if the correct amount of voltage is aplied, you cannot apply 2 volts to it and still get 100 watts if it needs 240 volts
Can you please leave Ohm's Law out of this for a minute. What we are talking about here is multiple ways of making a particular wattage, which is what the original poster that you replied to was trying to say that apparently slipped right by you. Do you deny that you can make a particular wattage in many different ways? I have shown you that yes, you can make a particular wattage in many ways but still you argue Ohm's Law to me.
I've thought about it for a minute and I see now where the misunderstanding lies. You're thinking that I'm saying you can raise one and lower the other in the same circuit and I'm talking about creating the same wattage in different circuits. Yes, you can have two different circuits both producing 100W total power using different combinations of amps and volts but you can't adjust a single circuit to make the same watts in different ways. Is that what you mean?
This is real interesting technology! I love this stuff! Every once in a while when I have a couple of hours I like to play around with the Peltiers I have in my toolbox. I'd really like to get a job working for one of the companies that produce peltier coolers and /or assemblies for different industries.
Hi RCSteve93, I am working with 170 watts peltier, so I want to ask you some question; What kind of paste have you used to join peltier with the headsink ?, Why did you use this paste?; is this paste easy to remove?, thanks.

@TheNuclearWatermelon why? at 0 celsius water Freeze at 100 it boils :) reagular room tempreture is about 22-25 celsius and you`re body temp is 36 celsius (37 and you are soon sick)
@TheNuclearWatermelon why should you need that? att 0 celsius water freez att 100 celsius it boils, 20-24 celsius is you´re room temp 36-37 is you´re body temp ;)
@russotragik I can answer that, you see, these two fans have "effective voltage" or RMS voltage (root mean square) of 12 volts which means they can run constantly at 12V without any problems. If you want to know the Maximum voltage of a device you multiply it's RMS voltage with the square root of 2, in this case thats:
12V * √2 = 16, 97 ; this means you can supply these two fans with a voltage of 16,97 but ONLY FOR A COUPLE OF SECONDS!
I hope this helped if you have more questions just ask :)
@phantom1000A Fuck fahrenheit! it`s just a stupid German that came up with that :P 0 F is 17,7 Celsius 100F is 37,8F (body temp of that stupid German guy that had Fever) water boils at 100c what about Fahrenheit? 212 F!! harder to remember and water freezes at? 32F also harder to remember :)
yes it was named after a german physicist, but we never used this scale here in germany. only a few american states and sometimes a few people in britain use it.
Hi, i am trying to do project for my school, can i run 4 peltiers (12v 60watt) at the same time with one transformer? and what is the best power supply to get the max cold?
hey man i have been looking on sites for this but much rather buy off line do you know where i should look like mabe a fridge repair shop please help much whould be a preciate thnx
Is there any way to control the cooling temp? Lowering supply voltage maybe? Also, if heat is applied to the cool side and the device has to cool it down does that then make the hot side hotter? Im going to cool RF Mosfets
Ok, I have this mini fridge... Instead of it being cool, i wanna make it a heat box. Can I just reverse the current? Do do i have to remove the peltier and flip it over... I wanna know before i attempt and accidently destory my cooler.
heat sync paste is a fine silver dust suspended in a silicone grease it is usualy white in color. the grey stuff you see here is jb weld epoxy used for almost annything. you can aslo mix super glue in with you're heat sync paste to mount the heat sync to the TEC.
Great demo on the TEC principal, Steve. I knew about peltiers way back in the pentium processor days.............o those days. I have a cuisinart cwc-600 wine cooler that uses TEC for cooling. I am repairing this for a friend of mine, and she complained that it stopped working after 2 days. I really think the unit works, but is a a victim an under engineered product. Anyway, thanks for the refresher course. P.S. I am now a subscriber to your channel :).
I saw a modified Miller bobcat welding machine supply power for a large "cooling" device once on a job site. The guy would place entire 5 gallon spring water bottles inside a box, and freeze them for the people operating the blast furnaces. It took about 10 seconds but it was cool as hell none the less. You can have ice water in hell...for 5 bucks! -was the motto on is shirt and truck. the bottles were used for keeping the hydration packs cool while operating 1800+ degree furnaces.
I <3 Fahrenheit. Honestly, I've just been raised with it, and Celcius is close to jibberish to me. My brain thinks: 80 degrees out = moderately hot.... 50 degrees out = moderately cold. :P
@ImaginativeBrowsing We should switch to metric. But many Americans don't want the hassles of having to learn a new system of measurement. Even if it's a far more logical and simpler system. So I don't thing we will see speed limit signs in kph any time soon in the US. For my own measurements I tend to use metric. Both my digital scales are set to metric.
@ImaginativeBrowsing Why need metric? Why all the big numbers? 6 FT (feet) or 182.88 CM centimeters.
0*F = freezing point of SALTwater, 0*C = freezing point of FRESH water. It's just a different angle of looking at things. Its a tool, learn both and stop complianing.
@kirkthecapt Except the saturation of salt in water can vary hugely, where as fresh water has far fewer variables. Ideally we should all just be using Kelvin.
@438426x1 Funny how that works in the United States we use Fahrenheit most of the time and Celsius some of the time so it works both ways about Celsius pissing us off but its not to hard to remember the difference.
i have 350 watt peltier junctions that can move some serious heat... the main problem is that they draw so much current! 15 volts and 25amps or so max... lol 25 amps is huge at 15 volts...
where can i purchase this peltier? and or all this stuff, and i was thinking of turning my locker in school into a fridge via this set up, any suggestions to how id go about doin this? thanks!
Currently implementing this technology to cool down the Radiator of my PC meaning that no matter how small the Rad is the PC will never go above room temp.
I am actually building a micro drink cooler with one of these. i ordered the peltier yesterday and have the heatsink/fan, BUT WHERE DO I GET THERMAL PASTE??? please respond before i get the peltier and fry it.
peltier elements rock! i have one too, but my cooling technique is not as good as yours but i get frost on the cold side as well and drops just spread over the surface and bing-frozen!
You keep saying its really cool, how cool is it. How many om's do you say a day.
pathman2 6 days ago
Peltier sucks juice like no tomorrow, and you still need to cool one side of the element.

can i point out that a lot of thermal paste is actually insulative as a pose to conductive.
you need a very thin but entirely surface covering layer. make sure both side have been cleaned with isopropyl alchahol.
my use for this is basically two of your arrangments with an alumium box section tube sandwedged between.
i then blow air through this ice cold tube and viola!!!! pc air condidtioning ive dropped internal case temps by over 10 deg C

Is there any way to control the cooling temp? Lowering supply voltage maybe? Also, if heat is applied to the cool side and the device has to cool it down does that then make the hot side hotter? Im going to cool RF Mosfets

I think I've been able to go down to -40C = -40F while I ran mine in a freezer (-28C = -18F). Wonderful stuff.

Ok, I have this mini fridge... Instead of it being cool, i wanna make it a heat box. Can I just reverse the current? Do do i have to remove the peltier and flip it over... I wanna know before i attempt and accidently destory my cooler.
Thanks

heat sync paste is a fine silver dust suspended in a silicone grease it is usualy white in color. the grey stuff you see here is jb weld epoxy used for almost annything. you can aslo mix super glue in with you're heat sync paste to mount the heat sync to the TEC.

Thanks for making this video. That JB weld seems to be doing good things, that may be what I need for my peltier units.

Great demo on the TEC principal, Steve. I knew about peltiers way back in the pentium processor days.............o those days. I have a cuisinart cwc-600 wine cooler that uses TEC for cooling. I am repairing this for a friend of mine, and she complained that it stopped working after 2 days. I really think the unit works, but is a a victim an under engineered product. Anyway, thanks for the refresher course. P.S. I am now a subscriber to your channel :).

Hi Steve;
This is a nice video- just the type I was looking for on the internet.
I would be interested to see if you have further experiments...

I saw a modified Miller bobcat welding machine supply power for a large "cooling" device once on a job site. The guy would place entire 5 gallon spring water bottles inside a box, and freeze them for the people operating the blast furnaces. It took about 10 seconds but it was cool as hell none the less. You can have ice water in hell...for 5 bucks! -was the motto on is shirt and truck. the bottles were used for keeping the hydration packs cool while operating 1800+ degree furnaces.

I <3 Fahrenheit. Honestly, I've just been raised with it, and Celcius is close to jibberish to me. My brain thinks: 80 degrees out = moderately hot.... 50 degrees out = moderately cold. :P

@ImaginativeBrowsing We should switch to metric. But many Americans don't want the hassles of having to learn a new system of measurement. Even if it's a far more logical and simpler system. So I don't thing we will see speed limit signs in kph any time soon in the US. For my own measurements I tend to use metric. Both my digital scales are set to metric.

@ImaginativeBrowsing Maybe because we don't live in Europe and like to use a normal numbering system.
Linkjoy123 1 year ago
@Linkjoy123
a normal numbering system? so you mean other temperature scales are not normal? ^^
by the way, do you know the history of fahrenheit and his way of creating the scale?
i think using the temperatures of the physical state of water is a better way to make a temperaturscale - 0-100

@ImaginativeBrowsing Why need metric? Why all the big numbers? 6 FT (feet) or 182.88 CM centimeters.
0*F = freezing point of SALTwater, 0*C = freezing point of FRESH water. It's just a different angle of looking at things. Its a tool, learn both and stop complianing.
kirkthecapt 1 year ago 2
@kirkthecapt Except the saturation of salt in water can vary hugely, where as fresh water has far fewer variables. Ideally we should all just be using Kelvin.

@438426x1 Funny how that works in the United States we use Fahrenheit most of the time and Celsius some of the time so it works both ways about Celsius pissing us off but its not to hard to remember the difference.

i have 350 watt peltier junctions that can move some serious heat... the main problem is that they draw so much current! 15 volts and 25amps or so max... lol 25 amps is huge at 15 volts...

conrad2468 2 years ago
Either ebay, or any computer shop in your area. If you're lucky, the heatsink comes with thermal paste already stuck to it.
P.S. Besides thermal paste, you can use thermal "tape", thermal glue, or thermal grease...

oh forgot to ask, do you apply thermal paste to both sides? Or do you just put the peltier on the cpu without thermal paste
speedsk8r010 3 years ago
(5 stars)
Is there any way to clean the surface of the peltier to boost the cooling of the cpu?
Also, would Arctic silver 5 work for this, or what thermal grease/paste do you recommend for a peltier cooler?
