Hi every body!

I'm trying to build a model of the heatsink. When I run the simulation and calculation thermal resistance,value of the heatsink thermal resistance is different with parameter in the datasheet .

Please tell me how I can build a 3d model and set thermal parameters for it!

Thanks and best regards,

Linh Le

Hi Linh Le

you first need to have a 3D CAD model of all components.

Now you need to do a transient thermal analysis, to know how long it takes your model to reach the desired temperature.

in solidworks simulation for thermal analysis must go on connections right click and contact set and select thermal Resistance.

You should apply the boundary conditions for your model such as temperature, coefiente convection, conduction ....

Thanks

Best Regards.
