Even your temperature variation in image 1 is negligible. If you post your model including your sim setup, you could get better assistance.
None of the boundary conditions are attached to surfaces when I import.
In the boundary conditions you used symmetry - review how this functions to make sure it is what you want.
The computational domain is smaller that the part.
This is a heap of power is a small area - so temperatures will be very high.
I think it is best that you run through the tutorials for Flow then re-address this problem.
Apologies, it seems I had the lids suppressed once I sent the part. If you un-suppress the lids the boundary conditions then become present. I shall re-upload the file I am unable to open that pdf that you have linked
For tutorials see Help, SolidWorks Simulation, Flow Simulation Online Tutorial. A few days spent here will be the bomb.
Change Computational Domain to 3D.
Computational Domain should include all of the geometry, lids....
The Power is un-assigned, and I do not see a Flat Plate to assign power to.
