This article introduces the content of the cooling fan is knowledge is the foundation of zui, this knowledge is the fan selection, users will xu, in contrast, on the basis of these, combined with their own specific requirements, to choose the suitable products. He said to the specific under below this knowledge:
the scope of application of heat exchange fan cooling fan is mainly to solve the computer communication, electronics, machinery, power supply of the cooling problem, reduce the equipment working environment temperature, prolong the service life of equipment. There is also a part of the equipment using the cooling fan air volume, air pressure to complete equipment functions, such as air table is to use the pressure of the fan can drift on surface of the table.
2。 The working principle of heat exchange fan
the cooling fan is used in substation with ac power supply: only one winding single-phase ac motor, the rotor cage type. When a single-phase sinusoidal current in the stator winding, the motor can produce an alternating magnetic field, the magnetic field strength and direction 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. This alternation pulse magnetic field can be decomposed into two at the same speed and direction of rotation are opposite rotating magnetic field. 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, the total electromagnetic torque generated by the rotor will no longer be zero, the rotor spun along the driving direction, wind cooling ac fans are created.
