Heat dissipation dc cooling fan and exchange heat radiator fan respectively suitable for use in those areas

Radiator cooling fan manufacturer focus wenling chi automotive air conditioning technology co. , LTD was founded in 2002 in wen ling, is a focus on research and development, production, sales, radiator cooling fan of high-tech enterprises. Produced dc cooling fans, ac cooling fan, blower, waterproof/dustproof cooling fan, EC conversion and the cooling fan, radiator dc cooling fan, car radiator cooling fan, mute radiator cooling fan, radiator cooling fan, turbo cooling fan, dc dc cooling fan, centrifugal fan, blower, air blower factory, new energy dc cooling fan, brushless motor, etc. , has been widely used in: communications equipment, UPS power supply, medical equipment, electric welding machine, industrial control equipment, household electrical appliances, air purification industry, automobile industry, projectors, beauty equipment, sports equipment, and other areas of the industry. Next we know about the radiator cooling fan with the difference between dc and ac and areas of application: a, heat dissipation dc cooling fan is the use of direct current (dc) to provide power supply: dc motor consists of stator and rotor of two parts, heat dissipation dc cooling fan on the stator poles ( Winding type or permanent magnet) , the rotor winding, after electrify, also formed on cooling dc cooling fan rotor magnetic field ( The magnetic poles) And an Angle between stator and rotor poles have, in the stator magnetic field ( N pole and S pole) Attract each other, is the motor rotation. Change the brush seat, can change the Angle of the rotor poles ( Assumptions in the stator pole to start edge Angle, heat dissipation dc cooling fan rotor polarity to the other side, by rotor pole pointing in the direction of the stator pole is the direction of rotation of the motor) Direction, so as to change the direction of rotation of the machine. Second, ac cooling cooling fan is used in substation with power supply: only one winding single-phase ac motor, the rotor cage type. Ac cooling cooling fan when single-phase sinusoidal current through the stator winding, the motor can produce an alternating magnetic field, the magnetic field strength and direction of interplanting sine law of change at any time, but is fixed on the spatial orientation, say again so the magnetic field is alternation pulse magnetic field. Ac cooling cooling fan the alternation pulse magnetic field can be decomposed into two at the same speed and direction of rotation are opposite rotating magnetic field generated in the rotor torque of two equal and opposite, making synthetic torque is zero, so the motor can't rotate. When we use the motor rotates in the direction of a force, If clockwise) When the rotation of the rotor and clockwise direction magnetic field cutting lines of magnetic force between the smaller; The rotation of the rotor and counterclockwise direction magnetic field cutting lines of magnetic force between the movement. This balance is broken, ac cooling the total electromagnetic torque generated by the cooling fan rotor will no longer be zero, rotor spun along the driving direction. Three, radiator cooling fan is widely used in machinery and equipment, medical equipment, arts and crafts, personal car, communications systems, automotive, home appliance and to keep the product, etc. Have quality, just have tomorrow! We always innovation, give priority to product quality, make each product, are treated as a work of art, strives for perfection, strive for the magnesium. We have excellent rust r&d team with many years of work experience, can according to customer requirements, make the efficiency of the development and design all kinds of ac dc cooling fan and brushless dc motor, water pump, meet and exceed customer expectations, won the industry users of praise and a steady stream of orders.
