Sanace cooling fan blower

Sanace cooling fan blower A blower is a device that operates without friction within the body and does not require lubrication. It is used to purify air, gas, and other harmful gases through the conveying medium, ensuring a clean and harmless production environment. Structurally speaking, the blower is composed of impellers, rotors, bearings, etc. Its mechanism is stable, reliable in operation, and the mechanical friction loss is very small. Therefore, the operating life of the blower is relatively long. Generally, cooling fans require lubrication during operation, while the impeller of the blower does not have friction during operation, so daily lubrication is not necessary. The discharged gas is clean and pollution-free, and the speed is also very fast. Due to the small gap between the various parts, there is very little emission, and the air volume is concentrated together, resulting in high work efficiency. However, the disadvantage is that there is a blind spot, which cannot be cooled in a large area and only targets small areas, And the flow rate of the blower can be determined by selecting the speed. Capital Technology Co., Limited is the chief agent of SANYO DENKI, one of the leading enterprises of the cooling fan industry.

Detailed explanation of Sanace cooling fan parameters?

Detailed explanation of Sanace cooling fan parameters? When you choose a cooling fan, it will have a parameter, which many people who do not understand the cooling fan do not know what these parameters mean. When you choose a cooling fan, it will have a parameter, which many people who do not understand the cooling fan do not know what these parameters mean. Take the SanAce fan as an example. Assuming you purchase a Sanace DC cooling fan, the parameters are as follows: Model 9GT0612P4G001 Current 0.56A Power 6.72W Speed 10000RPM Air volume 44.5CFM Wind pressure 243Pa Noise 52DB Sanace waterproof cooling fan Everyone has a certain understanding of the model, current, and power of the fan, which belongs to the fundamental definition of the device. Below, professionals from Sanyo's cooling fan manufacturer will provide you with a detailed explanation of these indicator definitions. Fan air volume Air volume refers to the total volume of air discharged or absorbed by the cooling fan per minute. If calculated in cubic feet, the unit of air volume is CFM; If calculated in cubic meters, it is CMM. The unit of air volume commonly used by heat dissipation fans is CFM (approximately 0.028 cubic meters per minute), and air volume is the most important indicator to balance the heat dissipation ability of heat dissipation fans. The larger the air volume, the higher the heat dissipation ability of heat dissipation fans. Fan pressure The air volume and air pressure are a pair of mutually limiting parameters. Generally speaking, the larger the air pressure, the smaller the air volume, while the larger the air volume, the smaller the air pressure. Two cooling fans of the same model, one with a larger air volume than the other, will definitely have a lower air pressure than the other. Fan speed Fan speed refers to the number of times the fan blades rotate per minute, in rpm. The fan speed is determined by the number of turns of the coil inside the motor, working voltage, number of fan blades, inclination angle, height, diameter, and bearing system. There is no necessary connection between the quality of the speed micro fan. The speed of the fan can be measured through internal speed signals or external stops. Fan noise Fan noise is related to friction and air activity. The higher the fan speed and air volume, the greater the noise generated, and the vibration of the fan itself is also an essential factor that cannot be ignored. Of course, the vibration of high-quality fans themselves will be very small, but the first two are difficult to control. To address this issue, we can try using larger fans. The working noise of a large fan at a lower speed should be smaller than that of a small fan at a higher speed under the same air volume. Another element that we are prone to overlook is the bearing of the fan. Due to friction and collision between the shaft and bearings during high-speed rotation of the fan, it is also a major source of fan noise.

How to select a fan? What is the performance of the Sanace DC fan?

How to select a fan? What is the performance of the Sanace DC fan? Do you know how to choose a fan? What performance fans are more advantageous? Let's take a look at it. The design engineer of all motors and electronic products that require fan cooling must determine the amount of air required for a specific system to dissipate heat. The amount of air required depends on understanding the power consumption of the system and whether it can carry enough heat away to prevent overheating of the system. Facts show that the service life of a system can decrease due to insufficient cooling systems, so design engineers should also understand that the sales volume and price of the system may decrease because the service life of the system does not meet user expectations. Let's introduce a Sanace DC fan. Sanace DC fan is a DC fan under the Sanace brand in Japan. This type of cooling fan has the characteristics of multi-function and is widely used in our daily production and life. The SanAce fan agent manufacturer will introduce to you in detail today what functions Sanace DC fans have. 1. FG (Frequency Generator) signal/speed signal output As we often refer to square wave output, this function mainly outputs a square wave signal from the inside of the fan, and the frequency of the signal represents the rotational speed of the fan. Conventional quadrupole fan: rotational speed=FG frequency * 30. That is, by reading the FG signal, you can read the rotational speed of the fan. 2. Temperature control function The ambient temperature of the fan operation is monitored through a thermistor, and the rotational speed of the fan is appropriately adjusted based on the temperature to achieve the purpose of energy conservation and noise reduction. 3. RD (Rate Detector) function The RD function is also commonly referred to as an Alarm signal. RD is low when the fan is running, and high when the fan is locked. Monitor the RD signal level to determine whether the fan is in normal operation or locked state. 4. Auto Restart When the fan is locked, the working current of the fan will be automatically cut off, and the fan will operate at a low current state, thereby protecting the fan from burning down due to high current; Another function of Auto Restart: The fan automatically outputs a signal to start the fan at regular intervals. When the fan is not in a locked state, the fan will be restarted and run normally. 5. PMW (Pulse Width Modulation) speed regulation function The so-called PWM refers to: pulse width modulation. It means that the frequency (period) of the pulse signal is fixed, and changing the conduction period and cut-off period of the pulse signal changes the rotational speed of the fan to achieve the purpose of energy conservation and noise reduction. 6. Voltage signal speed regulation Input a variable voltage signal to change the rotational speed of the fan to achieve energy saving and noise reduction purposes.

The relationship between wind pressure and air volume of the Sanace cooling fan

The relationship between wind pressure and air volume of the Sanace cooling fan When the heat dissipation fan rotates, it will generate air flow, which will take away the heat from the surface of the radiator, thereby achieving heat dissipation. In this process, the wind pressure and air volume of the cooling fan are two key parameters, and there is a certain relationship between them. Generally speaking, the wind pressure and air volume are determined jointly by factors such as the rotational speed of the fan, the shape and size of the blade, and the area of the inlet and outlet. Wind pressure refers to the amount of wind power generated by a fan per unit area, usually measured in Pascal (Pa). The higher the wind pressure of the fan, the greater the size of the wind force per unit area, which can drive more air flow, thereby increasing heat dissipation efficiency. Air volume refers to the amount of air flow passing through a certain cross-sectional area per unit time, usually expressed in cubic meters per hour (m ³/ h) Is the unit. The larger the air volume of the fan, the greater the air flow driven per unit time, which can also carry more heat away, thereby improving heat dissipation efficiency. The relationship between the wind pressure and air volume of the cooling fan can be expressed by the following formula: Air volume=area x wind speed Wind pressure=density x wind speed ² / two Among them, the surface integral represents the surface integral at the outlet of the cooling fan, the wind speed represents the speed of the air blown out by the fan, and the density represents the air density. Generally speaking, there is a positive correlation between the air volume and air pressure of the cooling fan, that is, the higher the air pressure, the corresponding increase in air volume. This is because the fan needs to generate a certain amount of pressure when generating air flow, and high air pressure can generate strong air flow, thereby increasing the air volume. However, in practical applications, in order to save costs, manufacturers need to give up part of the air pressure if the air volume needs to be relatively large. If the fan can push a large amount of air flow, but the wind pressure is small, the wind will blow to the bottom of the radiator. This is why some box fans have high speed and large air volume, but this is because the cooling effect is not very good. On the contrary, a higher wind pressure usually means a smaller air volume. If there is not enough cold air to complete the heat exchange with the radiator, the heat dissipation effect will also be poor. In normal use, the nominal maximum air volume is not the air supply volume obtained by the actual cooling fan, and large air volume does not mean strong ventilation capacity. If air is flowing, the airflow will be obstructed by the fins in the path, and its impedance will limit the free flow of air. It can also be said that the air volume of the cooling fan increases, so the air pressure decreases. Therefore, there must be an optimal operating point at which the slope of the fan characteristic curve is the smallest and the rate of change of the system characteristic curve is the lowest, that is, the intersection point of the fan performance curve and the wind resistance curve. Therefore, the performance of a cooling fan can usually be described by the performance curve of the fan. This curve reflects the wind pressure and air volume that the fan can provide at different rotational speeds. When selecting a cooling fan, it is necessary to combine the actual situation and determine the optimal fan speed and operating conditions based on the performance curve to achieve the best cooling effect. At the same time, it should be noted that the efficiency and noise of fans vary at different rotational speeds, so these factors need to be comprehensively considered when selecting a cooling fan.
