How to distinguish in the radiator cooling fan noise and sound?
Is used in general industrial production radiator cooling fan, to cooling and dust removal equipment, maintain the air circulation, etc. , heat dissipation of the cooling fan application range is very wide. So the radiator cooling fan once appear, noise and sound will not only affect the use of the radiator cooling fan performance, still can let people be agitated mental work. Share with you the last time, how to improve the quality of heat dissipation of the cooling fan, from the source to YiRongChuan technician will introduce for you today how the difference between noise and sound in the radiator cooling fan? Difference between noise and sound radiator cooling fan: 1, radiator cooling fan noise, heat dissipation of the cooling fan noise is due to the blade periodically under the export of the pulse power of uneven air; Such as blade itself and uneven distribution of blade pressure on, turns on the surrounding gas and noise disturbance also constitute parts of rotation; And due to gas flows through the blade to tear, vortex and vortex flow attached level from, cause the pulsation of the pressure distribution on blade vortex noise. For the same series of cooling fan, air volume supplied by wind pressure, noise is bigger also, therefore, should be the choice of reasonable cooling fan form according to the practical situation, too much allowance not only waste of energy, will also increase noise, disadvantages for us. For the same type of cooling fan, should try to choose the cooling fan of low speed running; For different type of the cooling fan, should choose low noise, and should not only consider the speed. 2, radiator cooling fan different sound: heat dissipation of the cooling fan is different, different sound and noise sounds only pure wind noise, and sound, in addition to the wind, there are other sound, With two or more of the voice) 。 Different tone might be due to bearing deformation or foreign body in it, and improper assembly and collision, or uneven motor winding coil, resulting in loose. General testing different sounds are close to the ear, subjective factors is bigger, it is not easy to identify, easy to dispute, if you are using is larger, the number of the cooling fan can examine, by means of spectral analysis equipment noise spectrum energy distribution to recognize the different sound. About how the difference in the radiator cooling fan noise and sound, will share here, today is generally a good radiator cooling fan will have high speed, low noise, long service life characteristics, wenling YiRongChuan is a company with many years experience in professional r&d, production, sales, radiator cooling fan products excellent company, the choose and buy of can meet your requirements.
