After using the Xiangxin AC cooling fan for a period of time, it needs to be maintained and maintained so that it can be used for a long time and have a standard lifespan. What are the maintenance tips for the Xiangxin AC cooling fan? Xiangxin Electronics will share with you.
The maintenance methods for AC cooling fans are as follows:
There are a wide variety of AC cooling fans, and here we mainly introduce small AC fans used for electronic product cooling. Widely used in the home appliance industry, mechanical industry, manufacturing equipment industry, and other products with ventilation and heat dissipation requirements.
The motor structure of the AC cooling fan is a cover level motor, with the rotor and impeller fixed as one unit. The air duct, positioning frame, and stator are integrated. This type of structure is simple, easy to produce, and very convenient to install and use.
Maintenance tips for Xiangxin AC cooling fan:
1. Open the shell of the device, then turn on the Xiangxin AC fan, turn off the power supply of the device, and use an air gun 2cm away from the fan to blow the fan; Then use industrial alcohol to wipe the dirt on the fan blades, tilt the body to adjust the gap position, and then use an air gun to blow out the dust inside the equipment. From the front of the device to the back of the device, it needs to be cleaned and then rotated repeatedly until it is clean.
The wind speed of the Xiangxin AC cooling fan is determined by various factors, two of which are the bearings of the AC fan,
Ball bearings: The long-term oxidation of air ions and the accumulation of dirt and dust in the bearings can lead to an increase in the friction resistance of the bearings, resulting in a gradual decrease in the speed of the fan.
Oil bearing: The AC fan with oil bearing mainly relies on the mutual friction between the stator and the coil to rotate, and the oil inside the bearing gradually decreases with the use of the fan, continuous operation, and time consumption, resulting in slower and slower wind speed when using the fan for operation.
3. The lifespan of AC fans varies depending on the usage environment. Assuming working in a standard environment, the lifespan of a typical AC ball fan is around 50000 hours, and the products of different cooling fan manufacturers may also differ. A typical AC oil bearing fan has a lifespan of 25000 hours,
4. Due to the repeated rotation of its bearings, wear and tear will shorten its lifespan, and the lifespan of high-quality manufacturers will reach 30000 to 35000 hours; The equipment needs to be cleaned thoroughly, at least once a month. The air inlet network should be kept clean to prevent obstruction of airflow, which can be cleaned with a soft bristle brush or compressed air.

The working principle of cooling fan
Using the principle of electromagnetic induction, the fan uses the Houle induction module as a synchronous detection device, controls a set of circuits, switches the winding electrification sequence, and generates a rotating magnetic field, a mechatronics engineering fan for electronic commutation. The cooling fan has obvious advantages in the aspects of wide speed range, light weight, environmental protection and energy saving, controllability, reliability, environmental endurance and economy, etc. , dominate. The cooling fan is powered by direct current. The DC motor is composed of stator and rotor. The stator has a magnetic pole (winding type or permanent magnet type) , while the rotor has a winding, after the staff electrified it, the rotor also forms a magnetic field (magnetic pole) , there is an angle between the stator and the rotor magnetic pole, in the stator and rotor magnetic field (N-pole and S-pole) under the mutual attraction, is the motor rotation. The cooling fan technician told us to change the position of the brush, you can change the direction of the rotor-stator magnetic pole angle (starting with the stator's magnetic pole, the rotor's magnetic pole is on the other side, and the direction from the rotor's magnetic pole to the stator's magnetic pole is the direction of the motor's rotation) , after this operation, the rotation direction of the motor can be changed.
What are the maintenance methods for DC cooling fans?
Store and maintain in the correct way to extend the service life of the DC cooling fan. The following high-quality fan manufacturers will provide you with detailed maintenance methods for DC cooling fans:
How to choose the right cooling fan or other cooling fans
The design engineers of all motor automation equipment and electronic products that require the use of cooling fans for heat dissipation must determine the air volume required for a specific system's heat dissipation
What is the difference between a DC fan and an AC fan?
The working principle of a DC cooling fan: It is driven by 4102 DC voltage and electromagnetic induction. 1653 converts electrical energy into machinery to drive the fan blades to rotate, relying on the coil and IC to continuously switch, and the induction magnetic ring drives the fan blades to rotate.
Bearing - an important component in the cooling fan
Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.
AC fan, mainly used for cooling electronic products, is a universal small AC fan. Widely used in the home appliance industry, mechanical industry, manufacturing equipment industry, and other products with ventilation and heat dissipation requirements.
