A recent movie “Hidden Figures” unveils the story of three amazing women and the transition from human to electronic computing during the mid-20th century. Computing has been evolving drastically, and higher performance consequently generates more heat. Overheated electronic devices not only decrease system performance, also potentially lead to system failure. The fan is the predominant option to dispatch the heat.
Fans are classified into two categories, DC and AC fans. In the past, AC fans were the first choice due to lower costs. Rapid developments in DC fan technology drive product costs lower than AC fans and improve productivity.
Energy-saving, cost-effective, low noise, long life expectancy, diversified dimension, and high efficiency are factors why DC fans are most commonly used nowadays. A DC motor is a rotary electrical machine that converts direct current electrical energy into mechanical energy, and forces produced by magnetic fields. Despite not supplying direct and consecutive airflow like AC fans and may need a converter for current exchange. Its low electromagnetic interferences and sufficiency to prevent overheating issues result in superior energy saving. DC fans are compatible with other DC devices, customized to system requirements and thus escalate operation efficiency, that which offer higher flexibility compared to AC fans. In addition, DC fans function best under low pressure and with reduced fan speed, the noise level can be kept at a minimal, and consume at least 50% less power than AC fans. DC fans are extensively adopted in a variety of applications, including computing, server, telecommunication equipment, automotive, IPC, and home appliance.
Zaward’s DC fan dimensions range from 30mm to 220mm, consumer to industrial, and axial to the blower. Besides standard fans, optional features (e.g. PWM, FG, AR, etc.), various bearing types for longer life expectancy (e.g 2ball, Duro, sleeve, etc.) and OEM/ODM services are offered.
