Thermal simulation of peltier element in fusion 360

Hi,

I am working a two staged cooling solution for a sensor using pelters elements in a vacuum chamber. (See TestSetup 1)

Peltiers elements or Thermal Electric Coolers (TEC) are devices that heat on one side and cool on the other when an electrical current pass through it.

In order to simulate the setup, I have applied a internal heat load corresponding of the electrical power of the Peltier in addition of the heat transfert from one side to another (ie 70W in my case for each Peltier)

Also I have added an applied temperature to the cool side of the first Peltier (-50°C in my case, that is what I want to obtain but I cannot for now)

And finally I have put a radiation load on all the surfaces.

I have done all that but it doesn't seem right (See TestSetup 2), I was wondering if you had more informations on how to simulate Peltiers elements. Is there a way to insert pelters elements and their characteristics ?

Any help would be very helpful, thanks.

I came across your post while trying to simulate a similar Peltier (TEC) setup in Fusion 360 for Electronics Cooling Simulation, and was wondering if you ever found a workaround or better approach to modeling this kind of thermal behavior?
I'd really appreciate any updates or insights you might have found since posting this.

Thanks in advance!

Hello, sorry I did not find any workaround to simulate the simulate the setup with results I was confident with, so I made real world tests. As I had little time, I couldn't double check after to see if the simulation was correct.

Good luck with your simulation, I hope you will be able to find a way to make it work!
