Thermoelectricity: testing Peltier Module

[Christophe]

I just received a small Peltier module commissioned following this discussion:



- I max .: 6.0A
- delta T max .: 67 ° C
- voltage: 15.4V
- Q max .: 15.4V
- number of couples: 127
- Melcor type: CP1.4-127-06L
- dimensions: 40 x 40 x 3.8mm
- weight: 21.8g

We play with?

Hello,
I had done some manips for Peltier students
see the video:

Hey Padawan! Back on this forum?

Superb video I will hardly get to do better ...

If I read well: 44.X ° C delta, 1.160 V and how much mA?

ps: oops the answer in the rest of the video

Hello and thank you

Delta T °?
Power restored?
Estimated yield?

[Christophe]

It's in the video maloche

Delta = 44.X-16.X ° C

1.83 V max and 25 mA

[Christophe]

Padawan, did you lead the experiment to the end? In order to make a complete energy balance? That is to melt all the ice and cool all the water and measure all the available electrical energy?

[Padawan]

ReHello !!
Yes indeed the family has grown and time passes ... !!!
For the little question I worked with modules
that we find everywhere, but there are monsters
with a fairly good performance and it worked! I saw some in labs of several hundred watts.
see absolutely the searches:

Oh, happy to see you again (it was not too hard at night bottle?)

And at high temperature what does a peltier look like? For example if I put my cell on a stove with a coupling liquid and a heat sink next to "cold"?

The hot = stove area = 200 to 400 ° C
The foid = air

What exactly does "delta T max .: 67 ° C" mean? That beyond it crame or that it produces "less"?

[Padawan]

Yes for operation on
a stove (I tested on a "Rosière") but be careful! the modules are welded together by an amalgam which melts very quickly even being protected by the ceramic plates, a hot spot must be found on the stove pipe! not too much! (150,180 °) .... but hey with this type of module either burn it or get it
3 to 4V with 200mA max .... you have to see beefier to keep
very high temperatures (see the famous site because what you are looking for is already the module HZ 20)
See you,

Here is a doc with curves in "cooling" operation: https://www.econologie.com/effet-peltier ... -3746.html and a long discussion on the subject:

And a little peltier effect module to buy
