CFD-Based Thermal Management Study of PCB Assembly to Assist Cooling Fan Design
CFD-Based Thermal Management Study
Wilde undertook a CFD-based thermal management study to evaluate layout options for a critical piece of test hardware.
Objectives
Evaluate subsystem package surface temperatures for a given layout and advise on suitability of cooling fan selection.
The Modelling Process
Geometry was imported to ANSYS Design Modeler for de-featuring and clean-up. ANSYS CFX was used to determine thermal and pressure-drop characteristics of a finned heat sink. The main analysis was undertaken with ANSYS Icepak.

Business Benefits
Determined layout constraints earlier in the design process thus reducing prototype iterations and development time.

…Pleased with the time Wilde take to understand our requirements…used them on a number of projects.
