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.

This is exactly what I needed, no it is even more than what I needed. Dude Thank you, you explain it very well
Great explanation and keeping the video quick and easy to follow. Great job man!
Thank you for posting this!
+Lanefasts No problem, hope it helped!
Well done sir.
An excellent video giving a very good introduction of the analysis.
What should we do if we had to glue both the parts together?
in that case you can apply a glue properties on the surfaces between the heat sink and the heat source
How to simulate soil and wet as well as dry air in the solidworks?
whats the convection coefficient for a passive heatsink thats outside the case

Hi the convention coefficient should be ranging from 5 to 25 W/mk for natural convection..may I know why you use 40W/mk. Thanks
I used 20 W/mk originally, but then increased it to 40 W/mk to simulate forced convection from the fans inside my computer case.
How should we choose the h value for the aluminum material?
On what basis is it chosen?
Can anyone explain this please?
Hi sir, i have some questions about the result of my simulation. How can i contact you? Thank you for the tutorial
how do u calculate heat transfer coefficient
Could you share the files for the components you used?
can you upload the part 2 please ?

@@JimBob1937 any suggestions?

Brother do you have thier files
I really need them
Can you please share the parts?
Without sharing this video is useless!!!
