Many companies design products with electronics that must function reliably at high altitude, typically 1,500m (5,000 ft) or 3,000m (10,000 ft) above sea level. Estimating the increase in operating temperatures is necessary to design and qualify such products. There are a variety of corrections used to account for this effect, many of which sacrifice accuracy for simplicity. … [Read more...]
Acoustic noise emission and communication systems in the next century
Acoustic noise emission is one of several physical design issues addressed during the design of telecommunications and information technology equipment. In most systems, noise is a by-product of the air-movers used for system cooling. The amount of heat dissipated in electronic systems cooled by forced convection is directly proportional to volumetric flow rate. The flow rate, … [Read more...]
Beyond the arrow plot – New methods for flow visualization
Within the realm of CFD-based flow analysis, the presentation of data is a vital issue. Researchers and developers need to gain insight, and non-technical managers and commercial staff have a critical need to understand the true ramifications of the data. Unfortunately, current methods for visualizing flow have limitations that make it difficult to interpret vast quantities of … [Read more...]
Improving productivity in electronic packaging with flow network modeling (fnm)
As the complexity and power density of electronics systems increase, so too does the demand for tools to improve both product quality and designer productivity. This is especially true for thermal designers who use Computational Fluid Dynamics (CFD) tools for thermal designs. Several important factors are driving this trend: System complexity has increased to the point that … [Read more...]
Cooling Electronics at High Altitudes Made Easy
Introduction High altitude air cooling has always been somewhat of a mystery to the uninformed. The first reaction to the situation is that there is just not enough air at altitudes greater than six kilometers (20,000 ft). At times this may be true, but many things can be done to improve the cooling and obtain an acceptable design. The most important thing to remember when … [Read more...]
