Basic knowledge of cooling fan:

Basic knowledge of cooling fans Radiators all need to accelerate the heat loss through forced convection of the fan, so the quality of a fan plays a decisive role in the overall cooling effect. Equipping with a high-performance CPU fan is also one of the key factors to ensure the smooth operation of the entire computer.   The operating principle of DC fan is based on the right-hand rule of ampere. When a conductor passes current, a magnetic field will be generated around it. If the conductor is placed in another fixed magnetic field, it will generate attraction or repulsion, causing objects to move. Inside the fan blade of the DC fan, a rubber magnet filled with magnetism is attached. Surrounding the silicon steel sheet, the shaft is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits that make the two sets of coils wound on the shaft work in turn. The silicon steel sheet produces different magnetic poles, and this magnetic pole and the rubber magnet produce repulsive force. When the repulsive force is greater than the static friction force of the lice fan, the fan leaves naturally rotate. Since the Hall sensor component provides the synchronization signal, the fan can continue to run. As for the direction of rotation, it can be determined by Fleming’s right-hand rule.   AC fan operation principle 〆 The difference between AC fan and DC fan. The former power supply is AC, and the power supply voltage will alternate between positive and negative. Unlike the DC fan power supply voltage is fixed, it must rely on circuit control, so that the two sets of coils work in turn to generate different magnetic fields. The AC fan has a fixed power frequency, so the magnetic pole change speed generated by the silicon steel sheet is determined by the power frequency. The higher the frequency, the faster the magnetic field switching speed. Theoretically, the faster the speed will be, just like the principle that the more poles of the DC fan, the faster the speed. same. However, the frequency cannot be too fast, too fast will cause difficulty in activation. DC fans are used on our computer radiators. Generally, a good fan mainly examines the air volume, speed, noise, length of life, and what kind of fan blade bearing is used. These parameters will be explained separately below.   Air volume refers to the total volume of air discharged or taken in by the air-cooled radiator fan per minute. If calculated by cubic feet, the unit is CFM. If calculated by cubic meters, it is CMM. The air volume unit often used in radiator products is CFM (about 0.028 cubic meters per minute). A 50x50x10mm CPU fan can generally reach 10 CFM, and a 60x60x25mm fan can usually reach a CFM of 20-30. In the case of the same material of the heat sink, the air volume is the most important indicator to measure the heat dissipation capacity of the air-cooled radiator. Obviously, the larger the air volume, the higher the heat dissipation capacity of the radiator. This is because the heat capacity ratio of the air is constant, and the greater the air volume, that is, the more air per unit time can take away more heat. Of course, the heat dissipation effect is related to the way the wind flows under the same air volume. Air volume and wind pressure Air volume and wind pressure are two relative concepts. Generally speaking, to design a fan with a large air volume, some air pressure must be sacrificed. 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 the heat dissipation effect is not good). On the contrary, if the wind pressure is large, the air volume is small, and there is not enough cold air to exchange heat with the heat sink, which will also cause poor heat dissipation. Generally, a heat sink with aluminum fins requires the air pressure of the fan to be large enough, while a heat sink with copper fins requires the air volume of the fan to be large enough. A heat sink with denser fins requires more heat than a heat sink with sparse fins. A fan with high wind pressure, otherwise the air will not flow smoothly between the fins, and the heat dissipation effect will be greatly reduced. Therefore, for different radiators, manufacturers will cooperate with fans with appropriate air volume and pressure according to needs, rather than a single fan that pursues large air volume or high air pressure.   Fan speed refers to the number of times the fan blade rotates per minute, the unit is rpm. The fan speed is determined by the number of turns of the coil in the motor, the operating voltage, the number of fan blades, the inclination angle, the height, the diameter and the bearing system. Speed ​​and fan quality are not necessarily related. The fan speed can be measured through the internal speed signal or externally (external measurement is to use other instruments to see how fast the fan rotates, and the internal measurement can be viewed directly in the BIOS or through software. Internally. The measurement error is relatively large). ? Because the ambient temperature changes, fans with different speeds are sometimes required to meet the demand. Some manufacturers have deliberately designed a radiator with adjustable fan speed, which is divided into manual and automatic. The main purpose of manual is to allow users to use low speed in winter to get low noise, and use high speed in summer to get good heat dissipation. Automatic temperature control radiators generally have a temperature control sensor, which can automatically control the fan speed according to the current working temperature (such as the temperature of the heat sink). The high temperature increases the speed, and the low temperature reduces the speed to achieve a dynamic The balance of the wind noise and heat dissipation effect to maintain an optimal combination.   Fan noise  In addition to the heat dissipation effect, the fan’s working noise is also a common concern. Fan noise is the size of the noise generated by the fan when it is working, which is affected by many factors, and the unit is decibels (dB). When measuring the noise of the fan, it needs to be carried out in an anechoic room with a noise of less than 17dB, one meter away from the fan, and aligned with the fan’s air inlet along the direction of the fan’s shaft, and the A-weighted method is used for measurement. The spectral characteristics of fan noise are also very important. Therefore, it is also necessary to record the frequency distribution of fan noise with a spectrum analyzer. Generally, the fan noise is required to be as small as possible, and there should be no abnormal noise. Fan noise is related to friction and air flow. The higher the fan speed and the greater the air volume, the greater the noise caused, and the vibration of the fan itself is also a factor that cannot be ignored. Of course, the vibration of a high-quality fan will be very small, but the first two are difficult to overcome. To solve this problem, we can try to use a larger fan. When the air volume is the same, the working noise of the large fan at a lower speed should be smaller than that of the small fan at a high speed.    Another factor that we easily overlook is the bearing of the fan. As the fan rotates at a high speed, there is friction and collision between the shaft and the bearing, so it is also a major source of fan noise. The source of fan noise is due to 〆   1〃 vibration. If the physical center of mass of the rotor and the center of inertia of the rotating shaft are not on the same axis when the fan rotor rotates, the rotor will become unbalanced. The closest distance between the physical center of mass of the rotor and the center of inertia of the shaft is called the eccentricity. The imbalance of the rotor results in the eccentricity. Parts of machinery. 2〃When the wind noise fan works, the blades periodically bear the pulsating force of the uneven air flow at the outlet, which produces noise. On the other hand, due to the uneven distribution of the pressure on the blade itself and the blades, the rotation of the surrounding air and parts Disturbance also constitutes rotating noise. In addition, the turbulent surface, vortex and vortex separation generated when the gas flows through the blades cause pulsation of the pressure distribution on the blades and generate vortex noise. The noise caused by these three reasons can be comprehensively referred to as “cutting wind noise.” Generally, fans with large air volume and pressure will have relatively large cutting wind noise.  3〃Abnormal sound Wind noise sounds only pure wind, but abnormal sound is different. When the fan is running, if there are other sounds besides the wind, it can be judged that the fan has abnormal sound. Abnormal noise may be caused by foreign matter or deformation in the bearing, collision due to improper assembly, or uneven winding of the motor winding, causing looseness, which may cause abnormal noise. The service life of the fan The service life of the fan refers to the trouble-free working time of the radiator product. The service life of high-quality products can generally reach tens of thousands of hours. In the case of similar price and performance, choosing a product with a long service life can obviously protect our investment.   The life of the fan is composed of various factors such as the life of the motor, the use environment, and the power supply. The most extensive form of air supply is to use an axial fan (that is, the most common type of fan) to blow downwards. The reason why it is so popular is because of its good overall effect and low cost. If the direction of the axial flow fan is reversed, it becomes an upward draft, which is used in some special models of radiators. The difference between the two types of air supply is the different air flow. When blowing, the turbulent flow is generated, and the wind pressure is high but it is susceptible to resistance loss. When the air is exhausted, the flow is laminar. The wind pressure is small but the air flow is stable. In theory, the heat transfer efficiency of turbulent flow is much greater than that of laminar flow, so it has become the mainstream design form. But the movement of the airflow is also directly related to the heat sink. In some heat sink designs (for example, fins that are too tight), the airflow is greatly obstructed by the heat sink. At this time, air extraction may have a better effect. As for the side blast design, it is usually not different from the top blast effect. A more effective improvement method is to establish a dedicated heat dissipation duct for the CPU, so that it will not be affected by the hot air near the CPU, which is equivalent to reducing the ambient temperature.   Although axial fans are widely used, they also have inherent defects. The axial flow fan is blocked by the position of the motor, and the airflow cannot pass through the middle of the blast area smoothly. This is called the “dead zone”. On a typical heat sink, it is precisely the middle fin that has the highest temperature. Due to this contradiction, when an axial fan is used, the heat dissipation effect of the heat sink is not sufficient.   Centrifugal fan is a completely different form of air blowing from an axial fan, and has gradually begun to be used in CPU heat dissipation. It is usually called a “turbo fan” by computer users. The advantage of this fan is that it solves the “dead zone” problem well. The difference between a centrifugal fan and a traditional fan is that its blades rotate in a vertical plane, and the air inlet is located on the side of the fan. The airflow received by the bottom surface of the radiator is more evenly distributed. There are no obstacles in the blowing direction of the centrifugal fan, so there is the same airflow in all positions. At the same time, the adjustment range of air pressure and air volume is larger, and the effect of speed control is better. The negative effect is the same as that of a high-power axial fan-high price and loud noise. Improve the design of the air duct Another way to solve the wind blind zone is to change the direction of the fan’s wind. The traditional way of installing the heat sink is that the airflow faces downward, that is, perpendicular to the CPU. After improving the air duct design, the fan was changed to blow sideways, making the direction of airflow parallel to the CPU. The primary benefit of side blowing is to completely solve the wind blind zone, because the airflow passes through the fins in parallel, the airflow speed is the fastest on the four sides of the airflow section, and the heat point of the CPU is located on one side. In this way, the heat absorbed by the CPU cooling base can be taken away in time. Another advantage is that there is no bounced wind pressure (usually when blowing downwards, part of the airflow rushes to the bottom of the heat sink and rebounds, which will affect the direction of airflow in the radiator, and the efficiency of heat exchange will be lost). The heat exchange efficiency is higher than that of the downward blowing.
