Dc cooling fan is mainly used in what place
In the process of using dc cooling fan, we can know that it is the use of direct current supply for its power supply, dc motor consists of stator and rotor of the two most parts are on the stator poles ( Winding type or permanent magnet) And the rotor winding, after electrify, also formed on the rotor magnetic field ( The magnetic poles) 。 So we can know, between stator and rotor pole with an Angle, and through the stator magnetic field ( N pole and S pole) The attraction of down running jobs. In addition, dc cooling fan has quick speed, good heat dissipation effect, long service life and so on many characteristics, then first used in the dc cooling fan what category? Below we will revolve around the question to discuss. Dc cooling fan first on what categories: dc cooling fan is to solve the automotive, electronics, machinery, power supply of the cooling problem, extend equipment life, reduce the temperature of the working environment of the equipment. There is also a part of the equipment the use of dc cooling fan air volume, air pressure to complete equipment function. Dc cooling fan used in positive pressure air duct, can put most of the heat will exhaust to the outside of the car. To allow devices to reach very good heat dissipation effect, also illustrates the heat dissipation is the necessities of car equipment, include mobile phone is the same now, heat dissipation effect are particularly prone to owe good crashing. Dc cooling fan used in overhead power cars can suck in CPU heat, but also can make their own temperature together. Small dc cooling fan power temperature will be lower, and the ability to prevent car flow dead zone exists in the top. If it is under the power car, dc cooling fan from outside the car directly into the wind, the power will be very cool, is conducive to the stability of the power supply, extension service life. Dc cooling fan of the first category will be Shared for us here today, in addition, dc cooling fan has run a long service life, low vibration, low noise characteristics. As the using condition and environment temperature changes, sometimes need different speed fan to satisfied the demand.
