SOLIDWORKS Flow Simulation: Electronics Cooling Module

SOLIDWORKS Flow Simulation: Electronics Cooling Module

Table of Contents

Thermal analysis of electronics is one of the most common applications for
SOLIDWORKS Flow Simulation. Flow Simulation’s user friendly approach to CFD
makes it easy to gain design insight and improve cooling performance. If you
currently use or are considering Flow Simulation for electronics cooling
analysis, you may be wondering, “Do I need the Electronics Cooling Module?”

SOLIDWORKS Flow Simulation is a versatile tool and can provide valuable
information for a wide range of electronics cooling scenarios without the
Electronics Cooling Module. However, the add-in extends the software’s ability
to accurately model specific situations with several enhancements. Let’s take
a look at what these situations look like without and with the Electronics
Cooling Module.

Printed Circuit Boards

Printed circuit boards are notable from a thermal standpoint because they
exhibit anisotropic material behavior. The layered structure results different
thermal conductivities within the plane and through the thickness of the

Chip Packages

Accurate thermal representation of chip packages is critical in an analysis,
as they are usually the main sources of heat. Creating true-to-life models of
components is very rarely feasible as packages are complex, involving many
different parts and materials, and internal details are not available from
chip manufacturers. Therefore, simplified models are used.

Heat Pipes

Heat pipes use the phase change properties of a working fluid to achieve very
high effective thermal conductivities.


Joule Heating

Heat is generated as electric current passes through a conductor. This is
commonly known as resistive heating or Joule heating.

Beyond these features, the add-in also includes an enriched engineering
database with a wide range of component, fan, and material information so that
you can spend less time sourcing information from manufacturers. It’s all
about convenience!

Hopefully this feature breakdown has helped you figure out whether or not the
Electronics Cooling Module will help you with your analyses. Check out
this video on our
YouTube channel to see the features in action.

We have Solidworks 2018 Premium. ButI can’t see insert–>2-resistor model. What will I do.

Hi bhryanthlye,

The capabilities described in this article are a part of SOLIDWORKS Flow Simulation, which is not included with SOLIDWORKS Premium. You’ll first need to go to Tools > Add-Ins, and check the box to enable that part of the program.

Then, after you have created a new project you’ll be able to access Tools > Flow Simulation > Insert > Two-Resistor Component (as long as your Flow Simulation license includes the Electronics Cooling add-on module). If not, you’ll need to create a traditional Volume Source or Surface Source as described above. I recommend reaching out to your local SOLIDWORKS account manager to confirm your licensing.
