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...]
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...]
