DC Fans

DC fans are electric-powered fans used to cool, ventilate, and circulate air in a variety of devices, components, and systems. They are commonly used in industrial and commercial applications, as well as in consumer devices, such as computers, laptops, and game consoles. DC fans are also popular for use in home and office climates due to their low-cost, high efficiency, and low noise levels. The EE92251B2-000U-999 DC fan is a popular choice for many applications.

EE92251B2-000U-999 Application Field and Working Principle

The EE92251B2-000U-999 is a high-performance DC fan designed for a variety of applications, including but not limited to, computers, laptops, server racks, game consoles, and other devices. It is composed of a motor, rotor, bearing, and impeller assembly, along with a cooling fan casing frame, thermister, and tachometer. The fan also includes a control circuit board and a voltage regulator.

The fan works in conjunction with the tachometer and voltage regulator to ensure that the appropriate amount of air is moved through the device or system. The motor turns the rotor, which is connected to the impeller assembly, causing a vortex of air and creating a low-pressure zone. The low-pressure zone pulls the surrounding ambient air into the fan, and the impeller directs the air into the cooling fan casing frame. The thermister and tachometer then detect the temperature and speed, respectively, and the control circuit board regulates the voltage to ensure that the fan operates at the desired level.

The EE92251B2-000U-999 is designed for high efficiency, low noise, and long-term durability. It offers a wide range of airflow options, from 31.06-92.2 CFM, with an air pressure range of 0.1-1.75 mm-H2O. It has a rated voltage range of 12-14 VDC, and is capable of achieving a maximum speed of up to 1200 RPM. The fan is also rated for operating temperatures up to 75°C and is protected by a PBT plastic housing.

The EE92251B2-000U-999 DC fan is an ideal choice for cooling and ventilation in many applications, due to its low-cost, high efficiency, low noise operation, and long-term durability. It is highly reliable and requires minimal maintenance, making it suitable for a variety of uses.
