You forgot to include thermal resistance which important for thermal compound or thermal pad that goes between the cpu and heat sink. You are assuming that heat flow without resistance from the cpu to the heat sink. Can you please show us how we can model thermal resistance in this example?
Part two is uploaded, but it's a stress simulation, not a thermal one. For more advanced thermal simulations I'd look elsewhere, but this is a very good intro.
@@hyperhektor7733, this video just covers the basic thermal simulation, where you define material types and convective cooling. However, solidworks also has fluid/flow thermal simulation. From that section you can model the cooling you'd expect for specific types of fluids (air, water, something else...etc), take things like radiative heating, gravity....etc into account, as well as model heat flow for parts that are not in conductive contact. Google/search for something like, Solidworks thermal flow simulation, to get ideas of what it can do.
@@JimBob1937 thank you for your suggestions. I just wanted to do some "simple" models like a DIY CPU aluminium&copper metal cooler with a fan. So i can optimise the desgin. Cool would be when heatpipes could be used (x%water+ x%alcohol based fluid)
@@hyperhektor7733, ah, I am thinking of the same. I'm an electrical engineer but am curious to try casting a water block since I got into jewelry and art casting a while back. Jewelry type investment captures very fine details. Curious to try casting since I can 3D print an additive manufacturing type design that I can then cast. In theory that should work, and allow a lot of interesting designs. Heat pipes are quite hard to simulate, if so, you'll want to look into the flow simulation electronics module, I think I recall seeing heat pipes there as a built in component.
