  • Introduction

When Heat Becomes the Design Constraint

In dense electronic assemblies, the enemy is rarely the circuit design itself — it’s the heat that circuit generates and has nowhere to go.

This case study looks at how a manufacturer of industrial control panels and electrical enclosures used ANSYS CFD to solve a recurring overheating problem that physical testing alone couldn’t diagnose fast enough. By adopting computational fluid dynamics software as part of its standard design process, the engineering team was able to visualize airflow paths, predict hot spots, and validate cooling performance digitally.

  • Company Background

Higher Component Density, Higher Thermal Risk

The company manufactures electrical control panels and enclosures for industrial automation, power distribution, and process-control customers across South India. As component density increased, heat dissipation became a growing risk that traditional design checks weren’t built to catch.
  • The Challenge

Guessing at Airflow Was No Longer Good Enough

Cooling design had historically been handled with rule-of-thumb vent sizing, standard fan selections, and — when in doubt — physical thermal chamber testing after a prototype was built. Components would run hotter than expected in real installations, even when they’d “passed” basic bench testing, because actual enclosure airflow patterns were never modeled…
