Characteristics of DC COOLING FAN? DC COOLING FAN is not unfamiliar to modern people, it is an indispensable cooling equipment in modern industrial machinery, cooling effect, long service life, simple and convenient operation, so DC cooling fan is widely used. How does the DC cooling fan work? The Control Circuit shall have a plurality of semiconductor elements contained in the interior of one or more ICS, mainly through a combination of a DC cooling fan rotor, a stator, and another auxiliary blade member There are also many manufacturers that produce many models specifically designed to control the design of motor IC circuits used to supply DC cooling fans. Different types of IC control circuits are different, but the main objective is to provide an effective correlation of functions and features used in the DC heat sink fan coil for more effective control and protection. With the rotating magnetic field, the rotating repulsion force of the driven Suction Fan, and the rotating magnetic field synchronous induction rotor commutation signal, and then the interaction of switching current through the coil of electrification, so that the DC cooling fan can continue to operate. Advantages of DC COOLING FAN: 1, DC COOLING FAN using the most advanced design, with large air volume, low noise, long life, corrosion resistance and so on. 2. High quality bearings, silicon steel sheet, enamelled wire, higher reliability. 3. It has good start-up characteristic and speed regulation function. 4, compared to the AC fan to compare energy conservation and environmental protection. DC COOLING FAN DISADVANTAGES: 1, DC COOLING FAN manufacturing process will be more complex, cost will be higher, the price will be a little more expensive
