Powerful Knowledge 12 - Thermal management in power electronics

Modern power electronic systems are highly efficient systems but all will loose a small amount of energy during operation which manifests itself as heat generated in the power stage. If not managed correctly, this heat will reduce system performance and significantly impair unit reliability and lifetime.
In this episode of our 'Power Knowledge' series, we look at different ways heat dissipation levels can be estimated through simulation and measured from real hardware.

Great seminar. Thanks, very informative. What is your thought with regards to the immersion cooling of power electronics components? It probably simplifies thermal design and increase the heat transfer. Are there particular things to watch out when considering the immersion cooling?

Thanks very much for your kind feedback. Immersion cooling of PE is a really interesting approach but not one I have practical experience with. What I think it will do is provide significantly improved heat transfer, especially from components which are harder to cool (e.g. magnetic parts). One interesting thing to consider is that the liquid is just a heat transfer mechanism so you will still need a way to couple heat out from the liquid and into the local ambient. There are some fluids from 3M which look interesting www.3m.co.uk/3M/en_GB/novec-uk/applications/thermal-management/immersion-cooling-of-power-electronics/#:~:text=Immersion%20cooling%20involves%20putting%20electronics,into%20the%20heat%20transfer%20fluid.

Can you specify what sort of IR thermogphy camera you are using??
