The introduction of a cooling fan impeller and blade.
On the choice of cooling fan, we tend to compare the wind pressure and air volume, air pressure and air volume for normal ventilation，need to overcome the resistance of the cooling fan ventilation trip, cooling fans must have overcome the pressure of the air resistance. This is the air pressure.Air pressure is one of the important indicators to measure the cooling fan performance. Wind pressure mainly depends on the shape of the blades, area, height and speed, the faster the speed, the greater the blades.Wind pressure, the greater the relative air duct design of heat sink is better able to maintain the wind pressure of the fan.
Cooling fan impeller made of dynamic balance, just as the car wheels to do dynamic balance, the wind curtain machine rotor also needs to do the work, in simple terms, is to keep wind turbines in the running state of balance, noise reduction, and extend the life of the fan. Dynamic balance is a consumption time work, in fact, the result is likely to be in certain parts of the rotor weight added.
Cooling fan blades is calculated, to make the distance between the blades desultorily, presents a kind of “not equidistant” situation: this is also very simple, is trying to turn a turbine and air to produce audio “irregular”, as “a” of the wind, the wind in the rather than focusing on a certain frequency band.Noise has two kinds of narrowband and broadband noise, regular narrowband noise easily attract people’s attention, annoying.Close to the nature of the noise and broadband noise, although can’t eliminate, but relative resistance “listening”, let a person not so upset.
