The creation time for each of these examples is in the range
5 - 30 min!
Optimum fin pitch
A large fin spacing decreases the total heat transfer
surface, a small fin spacing decreases the air flow. The optimum pitch
is a compromise. The points mark the
values that are physically possible.
Fin thickness optimization
The lower curve is for 1 mm fixed thickness. The upper curve has been
calculated with the internal fin optimization procedure checked. The
best value is ~0.3 mm, (not visible in the digram but presented in
the result list).
Bottom plate temperature profile
This image shows the temperature profile on the bottom plate of a heat sink with two
discrete heat sources. Can also be shown in 2-D.
Bottom plate thickness
If there are
discrete heat sources, a thick bottom plate helps to spread the
heat but it also decreases the available heat transfer surface.
The optimum thickness is a compromise.
In this example 2 - 4 mm.
Down load the demo version
This version is fully functional except that the heat sink depth not
can be changed.
