I am trying to simulate the heat transfer in a PV system. There, I am struggeling a bit with the thermal conduction. I try to explain as good as I can what I try to achieve and what I did so far, so bear with me reading this short text :).
So far, I have implemented:
- Heat transfer by sun irradiation (on solar cell level)
- Heat transfer with atmosphere by radiation & convection (on solar cell level)
To complete my simulation for now, I miss the heat transfer with atmosphere by conduction (on solar cell level)
I looked into several examples (Photovoltaic Generator, House Heating System, Motor Thermal Circuit) to get an idea of how the thermal conduction between different bodies may be simulated. In my understanding, I would need to use a thermal resistance between the two bodies. Another alternative suggested by literature is the one in the image below: putting the conductive heat transfer element in series with heat transfer by radiation/convection, where the "Conductive Heat transfer" elements are filled with the area & thermal conductivity of the cell. But here, I am struggeling with the thickness I should enter.
Which would be your implementation?
I hope my questions are clear. A consent would already be enough, although I prefer a more detailed explanation to understand Simulink/Simscape better and enjoy the software even more!
Thank you all in advance.
