DC cooling fanThe rotor includes DC cooling fan blades, which are the source of air flow and the fan axis, which are used to support the rotation of the balanced fan blades, the rotor magnetic ring, the permanent magnet, the key to push the magnetic stage to switch the speed, the outer frame of the magnetic ring, and the fixed magnetic ring. In addition, it also includes a supporting spring, through which the entire part of the nodule is fixed to rotate, the motor part, the production direction of rotation, and the ability to move the size of the rotation speed key. Its speed regulation performance is good, simple control.

The 1. DC cooling fan is to solve the heat dissipation problem of computers, electrical appliances, machines, and power supplies, lengthen the service life of the equipment, and reduce the operating environment temperature of the equipment. There are also some equipment that use the air volume and air pressure of DC cooling fans to complete the functions of the equipment.
2. DC cooling fan is used in the chassis of positive pressure air duct, most of the heat can be discharged to the outside of the chassis. Then let the equipment achieve a good heat dissipation effect, which also shows that heat dissipation is a must for industrial equipment, including the current mobile phones. If the heat dissipation effect is not good, it is especially easy to crash.
3. DC cooling fan applied to the upper power supply chassis can absorb the heat of the CPU in time, but together it will also increase its own temperature. Small DC cooling fan power supply temperature will be lower, and can prevent the top of the chassis airflow dead zone. If it is a chassis with a lower power supply, the DC heat dissipation fan directly enters the air from the outside of the chassis, and the power supply will be very cool, which is conducive to the stability of the power supply and extends the service life.
