DC cooling fans are a special type of fan that is widely used in electronic equipment, such as computers, communication equipment and power supplies. In the high temperature, heavy dust, humid air and other harsh environments operating equipment, all-metal high-temperature, dust and moisture DC cooling fan can reduce the operating temperature of the equipment, and extend the service life of electronic equipment.
DC cooling fan is mainly composed of stator, rotor, commutator and other components, of which the stator has a magnetic pole parts, the rotor has a winding, the formation of a magnetic field after the power supply, through the stator and rotor magnetic field of the N-pole and S-pole between the mutual attraction to run. The core components of DC cooling fan are stator and rotor, stator has silicon steel sheet and coil, rotor has permanent magnet and coil. A magnetic field is generated by an electric current, which in turn interacts with the magnetic field in the stator to create a repulsive force that turns the fan blades.
The specification parameters of DC cooling fans include size, rated voltage, fan speed, airflow, noise, bearings, service life and fan connectors. Among them, airflow is the most important indicator of cooling capacity. Wind pressure and airflow constrain each other, and the higher the speed and the higher the airflow, the higher the noise will be. The bearing of the fan and its own vibration is also the main source of noise.
The advantages of DC cooling fans include low inverter cost, high power factor, low loss, high efficiency, and good speed regulation. These advantages make them widely used in the electronics industry and mechanical equipment, and are expected to become an integral part of electronic products in the future.
The selection of DC cooling fan needs to consider factors such as speed, material, power, performance and brand. Sanyo cooling fan manufacturers suggest choosing SanAce brand, which is available in the industry for quality and quality. Ltd. is a professional R & D and production of cooling fans, product categories include axial, centrifugal, cross-flow, the direction of application contains the field of miniature fan, silent fan field, waterproof fan field, low noise fan field, Christmas air mould field and so on.
