CFD Helps Ensure Reliability for Mission-Critical Systems
Avionics systems today are complex electronics comprised of advanced semiconductor chips and printed circuit boards (PCBs), and the extreme environments they operate in present a major challenge for engineers to develop reliable temperature-control mechanisms. Chip or board failures from too much heat or cold can disable an entire system.
Safety and reliability are mandatory, and so engineers in the avionics industry use computational fluid dynamics (CFD) thermal simulation and analysis when designing and building their systems. In the past, development cycles were extremely long to ensure product safety and reliable performance. But today, with advanced CFD software such as FloTHERM XT, simulation can be frontloaded to develop accurate 3D simulation models for analyzing heating and cooling performance much earlier, speeding up the design cycle.
The white paper “Reliability in Avionics Systems–Managing Excessive Heat” describes how to use FloTHERM XT when designing avionics equipment. However, this white paper is also applicable to any electronics product, useful for both mechanical and electrical design engineers. It walks us through an example of a concept-to-prototype design for an electronic component that would be placed onto a circuit board that dissipates 30% more power than earlier designs.
FloTHERM XT provides a solid modeling engine that bridges mechanical engineering software (MCAD) with electronic design automation (EDA) tools such as Expedition Enterprise, saving valuable time, reducing cost, mitigating risks, and improving overall product quality. FloTHERM XT enables both thermal experts and design engineers to automatically create models and simulate complex designs easily and accurately.
