- Thermoelectric devices are semiconductor heat or refrigeration units which use the Peltier effect to create a heat flux between the two surfaces of the module. Learn more about how they function and their role in the thermal management of electronics.

Thanks. I disassembled one of these and was fascinated at the simplicity, but didn't know why it would work.
Do i need to put a gap between the heatsink in the cold side and hot side?
can both hot and cold be utilized at the same time say there's a section of a device i want hot but another section to be cooled so the heat dose not reach that section
Would it be more effective in dehumidifiers that are used in winters, when temperatures in the room drop to 5 deg C
I love this person’s voice so much. Serious I would love to hear him explain anything.
What maximum and minimum temperature can this achieve? Would it be useful in a car cup holder to keep your drink hot or cold?
Very important video.. thank you ❤️👍
You are very welcome, we are glad you found it helpful!
I almost disassemble my Black Shark Phone Cooler because of my curiosity. Thanks to this I didn't have to do it just to know how it works
We're glad it was helpful!
I watched this video because of the black shark also😅
Thanks now I know how to use that ☺️
what is the feasibility of using them to produce energy from excess heat? Ie a hot solar panel
How to select heat sink for different modules?? Like how you will know the thermal conductivity and dimensions of heat sink
So you can only work if I supply power to the power leads?
I remember hearing about these and I was hoping if I get one side hot the other side would get cold.
No you can heat it up and get a voltage out, pretty low but enough to run a stove fan
Tl;dr edition:
The part uses direct current (dc), to make one ceramic plate suck heat from the other ceramic plate
Dell need to look at this
Isme hi cepecity wala peltier module konsa aata he 24volt dc 50 amp
Hard to undertand how. It cool
Great
So you would use thermoelectric on a refrigerator that may be out in a garage where the temperature is not consistent?
Kathy, if we understand your question properly, it sounds like you may have a temperature situation where the temps get so lowthat you have to heat the storage unit (refrigerator)? Maybe we are misreading your question?
You might build a refrigerator from TEC's, that could be an approach in this case. You might also find using a TEC chiller or heater might be best too. ATS makes the TEChill family for this, but you can also consider ThermoTEK or LairdThermal.
I want to make my own personal mini air conditioner will the tec work in my project ?
Hi @Laserma That's a hard question to answer without alot more information. But we can say this: there are products like that on the market, you can see some of them here www.amazon.com/Thermoelectric-Air-Conditioner/s?k=Thermoelectric+Air+Conditioner (that link is not an affiliate link as ATS does not have an affiliate relationship with Amazon).
Now, just because there are products like that on the market, it doesn't mean your concept won't be better or more suited to your application, of course. This video might give you some help on such a project: czcams.com/video/AhDgUJc6VvQ/video.html
thank you for this video. Informative :)
Glad it was helpful @Jovan!
Can this be used in the automotive sector to replace the HVAC system within a vehicle?
It would not be efficient I don't think
I thought so!
What is the difference between a thermoelectric generator and thermoelectric cooler? The TEG generates electricity in a temperature difference. It seems the terms are used interchangeably.
Thermoelectric generators use the Seebeck effect to generate a voltage/power, while thermoelectric coolers use the Peltier effect which allows the device to be used as a cooling or heating agent.
@@heatsinks But are they physically different when we buy them?
@@pulkitsharmapremiumvideos9252 no u just need to buy peltier module
And seebeck and peltier are the reverse process
My son and I have one and put a black piece of aluminum on one side, heat sinks on the other. Then we mounted in on a rod pushed through the center of a parabolic mirror. The black aluminum heated up, the heat sinks drew heat away when the beam hit it, and we were able to generate current to push a small DC fan. Fun experiment.
Can I use TEC ASSEMBLIES to cool my CPU?
You could do that Liang, and off a desktop the energy needed to power the TEC would likely be available. In fact, the thermal team at Jubail University College have recently published a paper on this, you can see it here: www.sciencedirect.com/science/article/pii/S1018363918310936
Great .. how iam using this .. cooling fan for mobile???
If I understand your question properly, no the TEC is not a fan. It is solid state cooling so no moving parts. And it could be used for cooling virtually anything in a computer but the key is that the TEC does take energy (electricity) to do the cooling.
What if you soldered the wires to each other and applied heat to the 'hot side,' would the 'cold side' become cooler? I just want to apply heat and get cold, I dont care about electricity. Thanks
Same idea. Depending on the metals it'll just change the temperature differential. This isn't a good idea though since it can heat or cool too much and carry over to the other side; therefore losing efficiency. At this point you'll need a heat sink for the hot or cold side in case one side gets too hot or coId. Best to arrange the metals so that they hit the tempurature you need most efficiently.
Why is the output of Peltier Module.?
Hi Juvert, can you please help us understand whay you mean by "Why is the output of Peltier Module?". Do you mean how does it work or why does it work the way it does? Thank you!
What about the durability?
They are durable, but, alot will depend on your specific application.
I came across one from 1965.
can it make ice??
Maybe....our chillers will make ice, while testing a new chiller we froze the pipes across the test fixture!
Set this on my car amp never got hot again
What does N and P indicate? Are those chemical symbols?
Hi Jack, the N and P indicate types of semiconductors. A typical thermoelectric module is manufactured using two thin ceramic wafers with a series of N and P doped bismuth-telluride semiconductor material sandwiched between them. The N type material has excess electrons, while the P type material has a deficit of electrons. One N and one P make up a couple.
@@heatsinks Does N represent negative and P, positive? Are there non rare earth elements which could be used?
You spelled rigidity, 'ridigity'.
you didnt explain anything really... sheesh...
Thanks for stopping by our channel Locry and for taking the time to leave a comment. I'm not sure what your comment means. Peltier Coolers (TEC) are pretty simple. To that end, I think we've provided a basic understanding of them in our video. However, as an engineer, perhaps you were looking for more application oriented explanation? As engineers we understand that and so here is a white paper that explains the process to choose a TEC.
