DC Fans: 9WS0812M402 Application Field and Working Principle

Introduction

DC fans, also known as direct current fans, are electrically powered rotating machines mainly used to move air through a radian or circular device. They are mainly used in cooling and ventilation systems for appliances and computing components, as well as in the aerospace industry for cooling and ventilation of aircraft. There are many different types and sizes of DC fans, each with its own application field and working principle.

Types of DC Fans

DC fans are usually divided into two types, AC powered DC fans and DC-powered DC fans. AC powered DC fans are powered by an external alternating current (AC) supply such as the mains power and require special motors to convert the AC power to DC power for the fan to work. DC-powered DC fans are powered by an internal direct current (DC) supply such as a battery and do not require additional motors to convert the AC power to DC.
