DC Fans: Applications and Working Principle of FBK04F12H

DC fans are usually used in applications where a cooling device is required. This type of fan is typically used in the following fields: transportation, HVAC, electronics, telecommunications, and medical. Given their energy efficiency, low noise, and small size, DC fans are ideal for use in these areas. One particular type of DC fan is the Model FBK04F12H from CUI Incorporated.

The FBK04F12H is a seventy-millimeter (70mm) fan with a twelve-volt (12V) operating voltage. The fan can run at up to 8,000 revolutions per minute (RPM) and has a rated air flow of 14.3 cubic feet per minute (CFM). As a brushless design, the fan does not require the use of lubrication or brushes; thus, it has a longer lifelong operation. The fan also features built-in protection circuitry and a thermistor port for temperature feedback control.

DC fans work on the principle of electromagnetism. When electric current passes through a wire, a magnetic field is created around the wire. This then creates a force known as Lorentz force, which acts on the wire, pushing it in the direction of the current. By operating the fan’s motor using electric current, a thrust is created that causes the blades to spin. The spinning action causes a flow of air past the fan, providing cooling to the components in the system.

The FBK04F12H has a wide range of applications. It can be used in computers, home appliances, and automotive systems, among others. The fan is reliable and cost-effective, making it an ideal choice for applications that require cooling in a small, quiet, and energy-efficient environment.

In summary, the FBK04F12H is a DC fan with a twelve-volt operating voltage and a seventy-millimeter diameter. The fan has a built-in protection circuit and thermistor port, as well as a rated air flow of 14.3 CFM and can operate up to 8,000 RPM. The fan works on the principle of electromagnetism, with Lorentz force created around a wire in electrical current pushing the blades to spin and causing air flow. The FBK04F12H is suitable for a variety of applications, such as computers, home appliances, and automotive systems.
