For cooling heat emitting applications and electronics, air cooling is used to achieve high heat dissipation and heat transfer. In certain cases, air cooling is preferred for its reliability and compact assembly over liquid cooling, particularly when leakage may be a concern.
Though water transfers heat better than air, air cooling remains a highly competitive, efficient and cost-effective cooling practice.
Air cooling is used in situations where size matters and cooling is critical, for instance in power electronics, semiconductors, converters, inverters, LEDs and GPUs.
