AC fans are essential components in the realm of thermal management, especially designed to regulate the temperature within electronic systems and machinery. Powered by alternating current (AC), these devices primarily function by moving air—either to cool down components by expelling hot air or to draw in cooler air into a system. The main functions of AC fans include maintaining optimal operating temperatures, preventing overheating, and ensuring the longevity and reliability of electronic components and systems.
These fans are pivotal in a variety of settings, ranging from industrial to commercial and residential applications. They are commonly used in computer servers, telecommunications equipment, home appliances, and HVAC systems. AC fans are known for their durability, cost-effectiveness, and ability to operate at a constant speed. Notable manufacturers of AC fans include Delta Electronics, Orion Fans, and NMB Technologies.
