The air velocity problem [air conditioning]

In recent decades, the heat generated by electronic components has constantly been increasing. For equipment cooled by air, it has therefore been necessary to successively increase air velocity. This tendency is associated with many problems at the premises, cabinet and circuit board levels. Some of the problems are specific for each particular level but one problem is common for all of them, the power consumption of the fans. A condensed resume of the problems associated with high air velocities is made and some suggestions for future solutions are also given
