The unimpeded flow of air necessary for cooling electrical equipment is called what?

Explanation:
Cooling electrical equipment relies on air moving freely around and through it. When air can circulate without any mechanical help, heat is carried away by natural convection, or natural circulation of air. Warm air rises and cooler air flows in to replace it, helping keep components from overheating. The other terms refer to environmental conditions (damp or wet locations), how conductors are joined (pressure connectors), or labeling conductors/busbars—none describe the air movement that removes heat.
