Hello,
I am new to SimScale and I am trying to achieve a thermal solution for my system. My goal is to cool a Power Electronics Board with 6 GaN Switches, each with a power loss of 40W with safety margins included. I have ran a natural convection simulation for the board. The system includes the switches, Inductors, a vapor chamber for a set of three switches, and a heat sink that goes on the vapor chamber, respectively for the simulation.
I worry that the results that I have been getting are incorrect because I feel that there should be a larger heat gradient between the GaN switches and the Heat Sink. My questions is that am I running a natural convection simulation? If so, what are some ways that I may improve my simulation to get more accurate results?
