The characteristics and the structure of the heat dissipation dc cooling fan

Radiator cooling fan according to the power supply voltage type can be divided into cooling cooling fan and ac dc cooling fan, radiator dc cooling fan rotor is between bearing and housing is applied to realize dynamic coordination, fixed on the rotor blades, therefore, when the rotor rotation, with the rotor blades will turn up. Common cooling fan with ball bearing, and heat dissipation dc cooling fan in order to improve the stability of operation and increase the service life, usually adopt more advanced liquid bearings. So, about the characteristics and the structure of the heat dissipation dc cooling fan, how much do you know? A, the characteristics of the heat dissipation dc cooling fan: 1, efficient blade optimization design. 2, precision manufacturing bearing long service life. 3, high volume, high torque motor design. 4, heat dissipation dc cooling fan, air pressure, blowing rate, long life, low noise, good stability. Second, dc cooling of the cooling fan structure: outer frame: glass, the general for square, circular; Bearing: using the high precision ball bearing manufacturing; Blade: fixed outside the cooling fan rotor, outer rotor for plastic magnetic ring; Plastic disks, magnetic stripe: magnetization formed by magnetizing apparatus with magnets, magnetic stripe; : rotor blades and a magnetic stripe along the rotating parts of the radiator dc cooling fan; Stator: fixed not rotating part of the heat dissipation dc cooling fan, generally for the four big tooth quadrupole, quadrupole around two groups on the coil.
