How to Select a Peltier Module

Peltier modules, also known as thermoelectric coolers, are semiconductor devices that actively transfer heat from one side of the module to the other when a current is applied. As an important element in circuit design, Peltier modules are an efficient thermal management solution for cooling objects below the ambient temperature. In this video, learn more about the different types of Peltier devices, how to read performance graphs on a Peltier module datasheet, and how to specify the proper thermoelectric cooler for your intended application.

Yes, indeed, quite the useful observation, that I'm sure many people miss, that you need to dump the input power out the 'hot side', as well! I guess that choosing a heat sink, and mounting method, are quite critical to optimize performance!

Thks for keeping it simple for folks like me.

I have created project for masters on waste heat management from 60 ton furnace, I am getting 13.27KW output power from 27000 teg modules of bi te

Just checking to see if you would post a video on how you use the numb chucks hanging on the peg board behind you.

Yeah so I want to generate electricity by using my cabin's metal woodstove exhaust pipe. Do I just stick in the hot side of the unit onto the pipe with some traps or something, and as it heats up, it produces electricity into the wires, trough which I will lead it into whatever, or how would I convert heat into electricity instead of electricity into cooling?

The most common newbie frustration with TECs is figuring out that heat dissipation *capacity* is only minor detail when trying to obtain cooling performance anywhere near the theoretical. The most important factor is often overlooked: your *rate* of thermal conductivity away from the hot side.

You can slap on the biggest, fattest copper heat-sink and summon a tornado to blow air around it, but all you've done is add a large thermal buffer near the hot side, and you sit there baffled by the cool heat-sink fins & overheating CPU (or whatever) and conclude there's no difference whether the damn thing is on or not.

Then you start looking into water cooling and with your first aluminium cooling block you finally start to see results. Then you remember copper is a much better thermal conductor and you get an expensive upgrade. Maybe then you realise there are ways to immerse the hot side in your coolant and skip the metal interface completely. Oops - and one fried server later you finally discover heat pipes.

What we need is peltier clothes
The squares are attached to each other with elastic bands That goes on chest legs and arms
When someone drops their temperature and then rises it quickly it makes bllod circulate better
Exercise makes the body heat up and then when the blood temperature goes down the blppd moves better
Changing body temperature lets people live longer and healthier
It also treats
Heart problems
Asthma
Diabetes
Alzheimer's
And poor blood circulation issues

What is the most powerful type of pellet for cooling?
Because I didn't understand the video correctly
I hope you can tell me what is the most powerful type of pellet for cooling 😇

[ixcutamp]

How don't these have more widespread use?

They are literal het pumps that fit in the palm of your hand and yet we barely hear about them!

So many uses!

[powermachines]

great video
i have a doubt how did you decide that the heat pumped should be 40W for the Temperature difference of 30 degree?

[celmarfaemalim]

Can you sudjest me what kind of battery are suitable to sustain and to power up the Piltier module like that?

[totti]

How we select the model to function as an electric generator ? If I apply the 30 dT across the same module, provide 150 watt heat on the hot side and dissipate 110 watts on the cold side, will i get 10 amps and 40 watts of useful electricity ? At what voltage ? 4 volts? How can we calculate that?

[tajulislam]

Hi,
I wanted to cool 30 litter of water from 30°C to 22°C. How many paltier chip it will require or which model I should use. Please if anyone can help. Very urgent need

[wiktorbabiarz]

But how to force module to use exactly 10 A? When I power my module with about 11 Volts, the module use I=U/R ampers? Am I right?

[jenkijtuchinda]

Heat transfer should be increased while temperature difference increases (Heat transfer from higher temperature to lower temperature). But on the other hand, In the data sheet indicated that the heat transfer decreases when temperature difference increases. Is that conflict with the law of thermodynamics?

when powering a peltier module like a TEC19006 as example. Rated at 16v 6a, is it best to run it at 80% max power, so something like 16v and only roughly 4.8a? Or can we run these at max power at all times?

[crazycrab]

I am making a fridge for me camper van, is it best to have 2 small peltier say, 50w each, or 1 120w one, max output for my Veh is 180w, cig lighter

[yoshinoyajones]

can you use them to heat? I mam thinking side view car mirror.

[glowingunknown]

Does anyone know what is the smallest battery possible to use with a(n average size) Peltier module?

I'm trying make a small cooling box for a project, something that can be carried around easily in one hand.

It looks like 12v 6ah battery is necessary, but those are car battery size. Definitely too big.
Would a smaller lithium battery, the kind that fits in a power-drill pack work okay?

I have no knowledge of electrical engineering.
