Thermal simulation of a CPU chip which is attached to a heatsink in autodesk fusion 360.
There is a CPU in red, attached to a PCB board and that is attached to the aluminum heatsink.
A. Lets go to the simulation workspace first...
B. Study materials- set materials
C. Set Thermal Loads- Bodies- Select body of Chip
D. Thermal load set in Watts for a consumer level CPU
Fantastic video, just what i needed
Great to hear! Glad you liked it.
U R GOD RIGHT NOW. THANKYOU
I am god always ;). You're welcome.
Heyy!! amazing work!! I want to ask you: Do you have a manufacturing tutorial for this heat sink
I don't, but these are often extruded aluminum or copper.
Wow great vid, could u do another one but with a heat pipe+ fins type of cooler ?
That would be pretty cool. I want Fusion to get a CFD module to be able to do the heat pipe.
@@AvivMakesRobots I could design custom gpu cooler that would fit perfectly in my Ghost s1 (itx pc case) and then send it to some manufacturer on aliexpress ! ❤
Wait a minute. One of the major points of using a computer to do thermal calculations is for the software to 'figure' out the heat transfer coefficients (natural, forced, radiation view). Faster would be a hand calculation or spreadsheet for this sort of problem. Also what is the cooling fluid and how do you change its properties?
Yes, but hand calculations are not going to give you values for every single little crevice of a particular geometry. Think about how much more information you can glean from a gradient map such as this.
Turns temperature Unit to °F = loses all my respect
Lol. It is an antiquated system, yes.
LOL
Me too... i was about to say that....
@@carlasouza5306 Lol you guys are funny. In all seriousness, I may want to focus the tutorials on metric from now on. Most of the views are outside the US, so it would make sense.
Is a simulation like this possible when you have just a sink and no cpu heat source, and no given wattage? Just a temperature from the base, and natural convection
Yes, an implied heat source, but remember that there is no air flow simulation in this study (at least not yet). So your results will be limited.
How to consider height of fins in calculation if there height is different? ,as in your case the fins are of different size
The main consideration stems from how they break out from the main CPU heatpoint. For this design, I would make the ribs right in the center higher since they are more intimately connected to the CPU and the outer fins shorter to save on size and material.
are there any vapor chambers or heat pipes videos?
I have a few other simulation videos on here, but none quite like that. Maybe eventually!
I didn't get what is the airflow direction?
Your heatsink was plaсed with edges parallel to X-Y with Z pointed to the top. If Fusion asumes that your CPU placed at the bottom - ribs will not work as expected.
Unfortunately, Fusion does not yet have airflow direction settings. This is a "static" thermal intro in that regard.
@@AvivMakesRobots If it is true, then "convection" simulation is totaly pointless :(
The convection value is correct, it just doesn't have a specific direction. Solidworks and Inventor let you dial in more values for these.
I think the value for convective coefficient in Fusion is Average value, so doesn’t account the airflow direction. If you want to consider airflow direction, you have to use cfd analysis.
Like what i did: ruclips.net/video/HGJObpJZQEo/видео.html
@@DidiWidyaUtama That is exactly right! There is no CFD in this particular module.
how can i simulate the greenhouse effect. ii would like to simulate a closed case with a raspberry pi in.
You would set the pi CPU as the main heat source and select the walls of the housing as the containers of the heat.
@@AvivMakesRobots any link for that setting? how can i select my case as heat container?
How could you record this video with all those sirens making such a terrible noise? :P
I wonder that myself!
is it possible to get a tutorial on how to design your cpu?
Hi Yousuf, this should be fairly straight forward... Are you experienced with creating extrusions with different bodies in Fusion?
I want you to guide me to become professional at fusion 360
Hello, how can i contact you please ? Thanks

@@AvivMakesRobots hello, i sent an email but you didn't answer, let me know, THANKS
fILE?
Please check a site like grab-cad for a file of one. Any will work.
