DC Fans DC fans (direct current fans) are motors which use electrical direct current to rotate the fan blade so that air is pushed outwards. They are used in many industries, including automotive, healthcare, retail and industrial operations, to keep the environment cool and to protect sensitive equipment from overheating. DC fans also offer high efficiency and low noise levels, making them ideal for use in extremely sensitive areas.The 9HV0812G10021 is a model of fan from NMB, a leading manufacturer of DC fans. It is designed for use in server and network equipment, where air coolant is especially important.The 9HV0812G10021 fan has a rotor speed of 8300rpm and a fan diameter of 120mm, making it powerful enough to provide ample cooling for servers and networks. It also features a 4-pole motor and a dual-ball bearing. The dual-ball bearing ensures low noise even at higher speeds, while the 4-pole motor ensures more power and torque than traditional two-pole motors.The 9HV0812G10021 also has PWM – pulse width modulation – control, which allows for precise control of fan speed. The PWM control is especially useful in applications where the fan needs to operate within a certain range of speeds. It can also be used to increase fan speed if necessary, ensuring proper cooling even under changing conditions.As a fan designed specifically for servers and networks, the 9HV0812G10021 has the added benefit of being very energy efficient. It runs on 12V direct current and can draw up to 1.29A (7.14W) of power. This means the 9HV0812G10021 produces high airflow without significantly affecting overall energy use.In terms of its working principle, the 9HV0812G10021 works similarly to other DC fans. It has a rotor which is made up of electromagnets, which are electrically charged when the power is turned on. This causes the rotor to spin, pushing air outwards as it rotates. The amount of air pushed out, and the speed at which it is moving, is determined by the voltage supplied to the fan and the size of the motor.In conclusion, the 9HV0812G10021 is a powerful and efficient DC fan, designed specifically for use in server and network equipment. It has a high powered motor and a PWM control system, allowing for precise control of fan speed. Its energy efficient design also makes it an attractive option for customers looking to reduce overall energy costs.
