A bit more detail would be helpful.
How do you have your heat sources setup?
How refined is your mesh? If your mesh is coarse you could only have a few cells inside your solid bodies so the entire surface would be defined from the same nodes.
Have you taken a cut plot through the TEC to see if the inside of our heat sinks have gradients towards the TEC?
(I've never used the TEC feature to offer more precise suggestions, but I modeled them manually several times before that feature was added).
I don't have any heat sources in a sense. The TEC is given a current and generates the temperature differential, which can be seen in the figures I attached. The mesh is the default mesh generated, but there are a good number of solid cells and partial cells generated (at least enough to capture some sort of temperature differential). I have taken a cut plot, but it yielded nothing different than the surface plot.
I just don't understand why the heat sinks attached show that the TEC is heating one up and cooling the other, but it does not illustrate any sort of gradient.
how would you model the TEC without the feature that references the data base?
Sorry I misspoke, those projects actually used heat pipes where I related heat scavenging to temperature, not current in a TEC.
Based on my understanding of how SW creates the TEC (a perfect insulator with a temperature differential) your problem may be that your sinks are much better conductors than convectors. (Your 2 blocks are nearly uniform in temperature because they are losing so little to convection - but this seems unlikely at 10m/s)
Is Capture 3 your cut plot? If so turn off the solids so you can see the temperature inside the sinks.
That is my assumption with how SW models TEC's as well (A perfect insulator).
I thought that the 2 blocks being nearly uniform was due to there being so little convection as well, so that is why I cranked it up to 10 m/s and made them somewhat pin shaped (they were initially blocks).
I have looked at a cut plot of the solids and it is consistent with what the surface shows, uniform temperature.
If there was documentation that SW made available to explain how they are modeled, that would be great! But the help menu's provide no detail as to HOW they are modeled, only in how to set them up.
So I looked further into the assumption that the convection was too low, therefor making the sinks seem uniform in temperature. So I changed the scaling of the graph and had to make the scale span over a range of 1 K in order to see the gradient on one heat sink, and then change the temperature scale for viewing the other heat sink.
I also remodeled the heat sinks so they were much taller and narrower and I was able to get a temperature gradient.
Turns out I just had to change the temperature scale so I could see the gradient.
Thanks for the help Chris.
need more information or need you to post the model
first thing that comes to mind is post a cut plot
second, make sure your inputs for your tec are correct and you've defined it correctly
then make sure you're in the working range of the tec
and make sure that you set your graphs so that the max and min are high enough to show gradients and use a cut plot
also double check you've got the full understanding of the tec by going through the technical reference and solidworks kb
hmm, looks like you figured this out, when I went to post there were no other posts under yours
