Electronic Cooling Simulation Helps Reduce Design Time - Application Brief

Electronics cooling simulation is helping a major aerospace manufacturer reduce design time while minimizing system weight. Thermal management is important for safe and reliable operation of all electronic equipment, and is especially so for airborne systems. Yet it can take several months and cost on the order of $10,000 to build and test a single prototype for certain equipment. For Hamilton Sundstrand, a maker of power modules for aerospace and marine applications, these obstacles have been overcome by using computational fluid dynamics (CFD) software to evaluate the effectiveness of different designs. By using simulations to better understand the airflow within each proposed device, engineers can determine the best methods for heat removal before the first prototype is built. In this manner, the company can often find novel ways to improve thermal management while reducing component weight.
