The working principle of the cooling fan is realized according to the energy conversion, namely: electric energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit principle is generally divided into various forms. The performance of the fan will be different with different circuits. Bearing structure brief introduction The common bearings of cooling fan are: ball bearing, oil bearing and magnetic bearing. Ball bearing Ball bearing changes the friction mode of the bearing and adopts rolling friction. There are some steel balls or steel columns between the two iron rings, supplemented by some grease lubrication. This method more effectively reduces the friction between the bearing surfaces and effectively improves the service life of the fan bearing. Therefore, the heating capacity of the radiator is reduced and the service life is prolonged. The disadvantage is that the process is more complex, resulting in higher cost and higher working noise. Oil bearing Sleeve bearing is a sleeve bearing that uses sliding friction and uses lubricating oil as lubricant and drag reducer. It can be said that it is the most common bearing technology in the market. Due to its low cost and simple manufacture, many products, including well-known brands, are still in use. The utility model has the advantages of quiet in initial use, low noise and low price. magnetic bearing The motor of magnetic bearing adopts magnetic system (MS) design, which uses magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. The principle is that the magnetic induction line is perpendicular to the magnetic levitation line, and the shaft core is parallel to the magnetic levitation line, so the weight of the rotor is fixed on the running track, and the almost unloaded shaft core is used to support in the direction of the anti magnetic levitation line to form the whole rotor suspended on the fixed running track. Compared with the traditional ball bearing and oil bearing, the magnetic bearing has no mechanical contact, and the rotor can run to a very high speed. It has the advantages of low mechanical wear, low energy consumption, low noise, long service life, no lubrication and no oil pollution. It is especially suitable for special environments such as high speed, vacuum and ultra clean. In fact, magnetic levitation is only an auxiliary function, not an independent bearing form. The specific application must cooperate with other bearing forms, such as magnetic levitation + ball bearing, magnetic levitation + oil bearing, magnetic levitation + vaporization bearing and so on. Air volume wind pressure Wind pressure and air volume are two relative concepts. Generally speaking, under the consideration of cost saving by manufacturers, some wind pressure must be sacrificed to design the fan with large air volume. If the fan can drive a large amount of air flow, but the wind pressure is small, the wind cannot blow to the bottom of the radiator (this is why some fans have high speed and large air volume, but it is the reason for poor heat dissipation effect). On the contrary, high wind pressure often means that the air volume is small. There is not enough cold air to exchange heat with the heat sink, which will also lead to poor heat dissipation effect. Fan speed Fan speed refers to the number of times the fan blade rotates per minute, in rpm. The fan speed is determined by the number of turns of the coil in the motor, working voltage, the number of fan blades, inclination angle, height, diameter and bearing system. There is no necessary relationship between speed and fan quality. The speed of the fan can be measured by the internal speed signal or by the external speed signal. With the change of application and ambient temperature, sometimes different speed fans are needed to meet the demand. Some manufacturers specially designed cooling fans with adjustable fan speed, which are divided into automatic and automatic. The main purpose of manual is to enable users to use low speed in winter to obtain low noise and high speed in summer to obtain good heat dissipation effect. The automatic temperature regulating radiator is generally equipped with a temperature control sensor, which can automatically control the speed of the fan according to the current working temperature. If the temperature is high, the speed will be increased, and if the temperature is low, the speed will be reduced, so as to achieve a dynamic balance, so as to maintain the best combination point of wind noise and heat dissipation effect. Fan noise In addition to the heat dissipation effect, the working noise of the fan is also a common concern. Fan noise refers to the noise generated by the fan during operation. It is affected by many factors, and the unit is dB. When measuring the noise of the fan, it needs to be carried out in the anechoic chamber with the noise less than 17dB, one meter away from the fan, align the air inlet of the fan along the direction of the fan rotating shaft, and measure it in A-weighted way. The spectral characteristics of fan noise are also very important. Therefore, it is also necessary to record the noise frequency distribution of the fan with a spectrometer. Generally, the noise of the fan should be as small as possible and there should be no abnormal sound.
