Some common fan technical analysis indicators

　　We want a good performance with a cooling fan, a lot of factors which determine the ultimate fan cooling performance, including wind, speed, noise, length of life, what kind of fan bearings.

　　Obviously, the greater the amount of air cooling fan its cooling capacity is also higher. This is because the air in the heat capacity ratio is certain, larger air volume, which is more air per unit of time can take more heat. Of course, the same air volume flow of the cooling effect of the wind the way. Fan

　　In general, under the firm cost considerations, to design air volume fan, it is necessary to sacrifice some pressure. In case

　　Cooling fan can bring a lot of air flow, but pressure is small, the wind can not blow the bottom of the radiator, on the contrary, it often means big pressure on the small amount of wind, there is not enough cold air and heat exchange fins, can also cause poor cooling effect.
