Thermal problems are not always visible on the drawing

You may be dealing with:

• Electronics overheating inside a closed enclosure.
• Hotspots around sensitive components, circuit boards or power electronics.
• Uneven temperature distribution that affects component performance or reliability.
• Limited space for heat sinks, fans or other cooling components.
• Uncertainty about whether passive cooling is sufficient or active cooling is needed.
• A design that requires repeated physical testing to meet its thermal requirements.
• A new enclosure design that must dissipate more heat without increasing its size.

These challenges can be difficult to assess using component specifications or simplified calculations alone. Computational Fluid Dynamics (CFD) simulation helps engineers visualise heat transfer, airflow and temperature distribution inside an enclosure, making it easier to identify thermal risks and evaluate design alternatives before physical prototypes or costly redesigns.
