Published by Sohaib Alam on January 5, January 5, Modern electronic devices have smaller footprints and have power requirements that demand excellent thermal designs. Components that tend to overheat underuse degrade the reliability of the product resulting in costly redesigns and product breakdowns. To ensure and maintain enough cooling of the integrated circuits packaging, PCBs, and other electronic systems, engineers rely on ANSYS Icepak to validate their designs and products long before the actual product manufacturing takes place.

ANSYS Icepak also allows the engineers to rely directly on their solver for integrated electronic cooling solutions of the electronic applications ranging from simple integrated circuits to vast packages to entire data centers.

ANSYS Icepak solver has the capacity to solve issues using heat conduction, convection, and radiation heat transfer analysis. Icepak also includes other advanced capabilities such as modeling laminar and turbulent flows, predicting design performance under stress and has a huge library of heatsinks, fans, and other related materials to make solutions to everyday electronic cooling concerns. ANSYS Icepak is capable of many different designs and features previously which were deemed hard to simulate in the electronic cooling spectrum.

With ANSYS Icepak, the user can simulate, predict, and virtually work over any type of electronic equipment out there in the market or underproduction phase. ANSYS Icepak comes packed with an extensive collection of useful materials that can be easily assigned to different solids, fluids, and surfaces. Icepak offers a smooth and streamlined electrothermal CAD -centric approach to its interface, which results in native ANSYS users to easily use Icepak without much of a hassle.

The built-in CAD geometry healing functions and geometry cleanup options along with many other different editing options facilitate the easy simulation setup and analysis. A vast commercial library complementing the unique designs and features of Icepak allows the designers to solve thermal problems at their fingertips. ANSYS Icepak has built-in automated mesh generation capabilities that allow the users to customize their meshing parameters with a convenient slider bar.

This allows the users to refine the mesh and optimize the trade-offs between the solution accuracy and the computational cost. The slider bar meshing further allows the user to fine mesh their designs where the velocity and temperature gradients are high while having a coarser mesh where these gradients are small. This allows the users to significantly lower the computation time and work closely on the areas in the design which matters to the thermal properties of the proposed design.

ANSYS Icepak contains a full suite of quantitative and qualitative post-processing tools to generate full-scale animation, meaningful graphics, and in-depth reports that can readily convey the simulations results to others. Icepak can easily simulate temperature contours, fluid-particle traces, iso-surfaces, velocity vectors, iso-surface displays, x-y plots of the results, and many other visualization features.

Customized reports, along with images, can automatically be created for distributing results, interpreting the trends as well as to report the blower and fan operation points. With Simplorer being a multi-domain system modeling platform, the users can easily work between the ANSYS ecosystem without compromising the usability or accuracy of the software or their designs.

This allows the users to easily predict the component junction temperatures that are not a direct function of the boundary condition. The following is the sample geometry used.

As seen in the sample geometry, there exist other components as well, along with the heat sink. Since our focus region is only the heat sink, we will use the simplify operation to transform the heat sink body into a valid Icepak object. To do so, follow the steps shown in the image below. The heat sink is identified as a polygonal Icepak block. For the CAD bodies in your design or as in the case of the sample geometry, to maintain their true shape, use the simplify operation with the simplification type set to level 3.

Doing so will result in the body to be designated as a CAD shape in the Icepak solver. The user can then set the Facet quality to determine the accuracy of the geometric representation in Icepak. For the remainder of the objects, that are objects except for the heatsink and the transformer of the sample geometry, set the Icepak object type for them as well. To do so, select the chips and board bodies via the tools command and select the Icepak object type.

Under the detail pane, set the Icepak object type to block.

After all the objects are labeled and verified, return to the project page and link the DM cell to a new Icepak component system and then transfer the system.

After all the designs and parameters are set for the Icepak system and the meshing is done as per requirement, you can then link the analysis systems together. The user can use the mesh slider to have a finer mesh near the heatsink region and a coarser mesh around other regions. The systems can be linked as per user requirements. After all the systems are linked together, the user can then import the thermal load from the Icepak body.

After the thermal loads are imported and set, the user can preview the thermal loads as shown in the image below.ANSYS Icepak provides flow and thermal management solutions for many types of electronic design applications.

However, I cannot quite find out how to create such a boundary condition on a surface. Has anybody here done such a thing or have an idea on how this might be accomplished?

The model was created in Solidworks, taken through Spaceclaim to create fluid regions and convert everything to Icepak bodies and then bought into Icepak. I have enabled multi-level meshing and the mesh looks good with a good minimum face alignment.

However, when I run the solution for iterations, the residuals start to diverge around 50 iterations. On closer inspection, I observe Fluent gives me a warning before solving which says 'Material of cell zone 25 is glycol, while material of cell zone 82 is air. This will adversely affect the solution. Please correct the setup. The shaded regions represent fins. Could anyone let me know how I go about correcting this or checking where exactly these cells are? Material of cell zone 25 is glycol, while material of cell zone 82 is air.

You will see this error if the two fluids i. This could be near the opening where the coolant is introduced or some other location where the mesh is coarse such that the glycol zones are touching the air zones.

You would need to closely inspect the areas that are carrying glycol. Suggestion: Don't have any fluid channels for the cold plate enclosure. Make it one solid body.

Then for the fluid channels i. Then in Icepak, use meshing priority to assign a higher meshing priority to the fluid glycol channel. Home Leaderboard Activity Badges. You must enable JavaScript to be able to use this site in full.
