DC Fans

DC fans refer to fans or blowers that use a DC motor as its motor. They are popular components in many electronics and electrical appliances, due to their small size and price. In particular, DC fans are widely used in small computer cases and computer cooling systems. For these applications, 9AH0812P4G04 can be a excellent choice.9AH0812P4G04 is a common DC fan, which use sleeve-bearing design to provide reliable performance over a long product lifespan. It is an 80mm x 38mm brushless DC fan with 4-wire PWM control. 9AH0812P4G04 has a maximum air flow rate of 34.34 CFM, with a maximum speed of 3500 RPM and a maximum noise level of 41.2 dB(A).

Application Field

9AH0812P4G04 has wide application fields and can be used in many different scenarios. For example, it is most commonly used in desktop computers and other computer cooling systems, to improve system performance and reliability. It is also used in some industrial equipment, such as 3D printers, CNC machines and machine housings.

Working Principle

DC fans work on the principle of electromagnetic induction. An electric current is passed through a coil, which produces a magnetic field. This magnetic field interacts with the magnetic field generated by permanent magnets on the fan, causing a rotation. By varying the amount of electrical current, the speed of the fan can be controlled. This is an important advantage of DC fans, as it allows for better temperature control of the system. The rotation of the fan generates air movement, resulting in an air flow. This air flow is used to cool down the system by dissipating heat away from sensitive components. It can also be used to blow air away from parts, such as 3D printer filaments, to prevent jams and other problems.

Conclusion

9AH0812P4G04 is a popular DC fan, which is widely used in desktop computers and other computer cooling systems, as well as some industrial equipment. It uses sleeve-bearing design, with 4-wire PWM control, to provide reliable performance over a long product lifespan. 9AH0812P4G04 has a maximum air flow rate of 34.34 CFM, with a maximum speed of 3500 RPM and a maximum noise level of 41.2 dB(A). The working principle of DC fans is based on electromagnetic induction, which allows for precise control of the fan speed. The generated air flow is used to dissipate heat from components and blow air away from parts, preventing systems from overheating and other problems.
