2.1. What is Ansys Icepak?

Ansys Icepak is a powerful CAE software tool that allows engineers to model electronic system designs and perform heat transfer and fluid flow simulations that can increase a product’s quality and significantly reduce its time-to-market. The Ansys Icepak program is a total thermal management system that can be used to solve component-level, board-level, or system-level problems. It provides design engineers with the ability to test conceptual designs under operating conditions that might be impractical to duplicate with a physical model, and obtain data at locations that might otherwise be inaccessible for monitoring.

Ansys Icepak uses the Fluent computational fluid dynamics (CFD) solver engine for thermal and fluid-flow calculations. The solver engine provides complete mesh flexibility, and allows you to solve complex geometries using unstructured meshes. The multigrid and pressure-based solver algorithms provide robust and quick calculations.

Ansys Icepak provides many features that are not available in other commercial thermal and fluid-flow analysis packages. These features include the following:

  • accurate modeling of non-rectangular devices

  • contact resistance modeling

  • anisotropic conductivity

  • nonlinear fan curves

  • lumped-parameter heat sink devices

  • external heat exchangers

  • automatic radiation heat transfer view factor calculations
