How to choose the appropriate axial flow fan according to the application scenario

How to choose the appropriate axial flow fan according to the application scenario Axial fans are widely used in various electronic devices, and different models of axial fans have differences in performance. Differences in air volume testing for different models of axial fans and how to choose the appropriate fan. 一、Differences in Airflow Testing of Axial Fans of Different Models 1.Size difference: The size, number, and shape of blades of an axial fan can all affect its airflow. Generally speaking, larger axial fans have a higher air volume, but the specific amount needs to be determined based on actual test results. Fan size: Generally, the larger the impeller diameter, the larger the area swept by the fan, and at the same speed, the greater the air volume. For example, large axial fans are suitable for exhaust in places such as dust and gravel fields, as they can generate a large amount of air flow; Small axial fans are used for ventilation and heat dissipation of mechanical equipment, with relatively small air volume. 2.Motor performance: The power and speed of the motor can also affect the airflow of the axial fan. High power, high-speed motors typically generate greater airflow. Motor type and power: Different types of motors have different characteristics. For example, direct current motors (DC) have the characteristics of small size, light weight, and high efficiency, while permanent magnet motors (EC) have high efficiency, energy conservation, and environmental protection. The higher the power, the more it can usually drive the fan to operate at a higher speed, thereby generating a larger air volume. 3.Design optimization: Some special axial flow fan designs, such as air guide design, shock absorption design, etc., can improve the stability and uniformity of their air volume, and enhance their performance. 二、How to choose the appropriate axial flow fan according to the application scenario 1. Consider the usage environment: Choose a suitable axial fan according to the different application scenarios. For example, in industrial equipment that requires a large amount of heat dissipation, axial fans with high air volume and good heat dissipation effect should be selected; In situations where a quiet environment is required, a low-noise axial fan should be chosen. Environmental factors: If the usage environment is harsh, such as high dust and humidity, a fan with a higher protection level should be selected to prevent dust from entering the motor or causing faults such as short circuits. In environments with flammable and explosive gases, explosion-proof axial fans should be selected. Noise restriction: In some places with high noise requirements, such as offices, hospitals, etc., low-noise fans should be selected for operation. Generally speaking, fans with lower speeds and more blades produce relatively less noise. 2.Consider installation space: The size of the installation space will affect the selection of axial flow fans. In situations where space is limited, axial fans with moderate size and air volume should be selected to ensure their normal operation and save space. At the same time, the installation method of the fan should be considered, such as wall installation, pipeline installation, etc., to ensure that the installation is firm and does not affect the activities of surrounding equipment and personnel. 3.Consider maintenance and cost: Different models of axial fans also have differences in maintenance and cost. When choosing, factors such as service life, maintenance convenience, and purchase cost should be considered, and the pros and cons should be weighed comprehensively. Cost factor: The prices of fans from different brands and models vary, and fans with higher power have relatively higher operating costs. Therefore, it is necessary to consider both budget and usage needs to choose products with high cost-effectiveness. 4.Reference air volume test data: You can refer to the air volume test data of professional institutions to understand the performance of different models of axial fans, so as to more accurately select the appropriate axial fan. Air volume requirement: Determine the required air volume based on the actual usage scenario. If used for ventilation in large factories, high air volume fans are required; For cooling small devices, choose a fan with lower air volume. The specific air volume value can be determined by calculating the spatial volume, air exchange rate, and other methods. 三、case study Taking air conditioning in household appliances as an example, it requires a large amount of heat dissipation during operation. When choosing an axial flow fan in an air conditioner, factors such as air volume, noise level, and usage environment should be considered.

Characteristics of SanAce centrifugal fan

Characteristics of SanAce centrifugal fan 1、Definition of centrifugal fan Centrifugal fan (centrifugal fan) is a special type of fan structure, with its core component being a motor located at the center. The motor is equipped with an impeller (feather root car), and unlike axial fans, it does not have a frame similar to axial fans. Centrifugal fans generate centrifugal force through the rotation of the impeller, which turns the inhaled air 90 degrees and discharges it radially from the side. This unique wind discharge method makes it significantly different from axial fans in terms of aerodynamics. 2、Structural characteristics of Shanyang SanAce centrifugal fan Central motor design: The SanAce centrifugal fan places the motor at the center of the fan, which makes the entire fan structure more compact and also facilitates better control of the fan's operating state, ensuring stable rotation of the impeller. Frameless structure: Unlike axial fans, SanAce centrifugal fans do not have frames. This design reduces resistance during air flow, improves air flow efficiency, and enables the fan to more effectively draw in and exhaust air. Equipment of inlet nozzle: In order to suction air more efficiently, SanAce centrifugal fans are usually equipped with an inlet nozzle. By clearly separating the suction and discharge spaces, the inlet nozzle can help the fan more effectively suck in air, thereby maximizing the capacity of the centrifugal fan and improving overall ventilation efficiency. 3、Performance characteristics of Shanyang SanAce centrifugal fan The main features include efficient heat dissipation, high static pressure and high air volume, energy saving and low consumption, waterproof and dustproof, low noise, and long service life. P-Q characteristic curve: The P-Q characteristic curve (air volume static pressure characteristic curve) of SanAce centrifugal fan is close to a straight line, which is significantly different from the characteristic curve of axial flow fan. The P-Q characteristic curve of axial fans usually has a flat rotational stall region, while centrifugal fans do not have this region. This means that centrifugal fans have a wider range of applications in terms of ventilation resistance and working point position compared to axial fans, and can better adapt to different ventilation needs. Energy consumption and noise performance: The energy consumption curve and sound pressure level curve of SanAce centrifugal fans may vary depending on different models. At the same operating point, using a centrifugal fan may result in lower sound pressure and lower energy consumption than using an axial fan. This makes centrifugal fans have significant advantages in situations where strict requirements are placed on noise and energy consumption. High static pressure and strong wind suction capacity: SanAce centrifugal fans have the characteristics of high static pressure and strong wind suction, which makes them very suitable for overall air replacement inside large equipment and heat exchangers that require a large amount of moving air. In these application scenarios, centrifugal fans can effectively promote air flow, achieve efficient air circulation and heat exchange, thereby meeting the heat dissipation and ventilation needs of large equipment. Certified by multiple international standards such as UL, CSA, and EN, and complying with the ROHS directive, the product is environmentally friendly and pollution-free, ensuring its safety, reliability, and environmental friendliness 4、Application scenarios of SanAce centrifugal fan Internal air replacement of large equipment: In large industrial equipment or data centers, the air inside the equipment needs to be regularly replaced to maintain a good working environment. The SanAce centrifugal fan, with its high static pressure and strong wind suction capacity, can effectively discharge the hot air inside the equipment and introduce fresh cold air, achieving rapid replacement of air inside the equipment and ensuring stable operation of the equipment. Air propulsion of heat exchangers: Heat exchangers are important equipment used in many industrial systems to achieve heat transfer. In a heat exchanger, a large amount of air flow is required to remove heat and achieve efficient heat exchange. SanAce centrifugal fans can provide powerful aerodynamics, pushing air to flow quickly in the heat exchanger, improving heat exchange efficiency, and ensuring stable operation of the system. Other occasions that require a large amount of air movement: In addition to the above application scenarios, SanAce centrifugal fans can also be applied to other occasions that require a large amount of air movement, such as ventilation systems, air conditioning systems, etc. In these systems, centrifugal fans can effectively promote air flow, achieve air circulation and exchange, and create a comfortable living and working environment for people.

What are the differences in heat dissipation effect between trapezoidal fan blades and trapezoidal fan blades

What are the differences in heat dissipation effect between trapezoidal fan blades and trapezoidal fan blades In the design of SanAce cooling fans, the shape of the fan blades does have an impact on their cooling effect. Trapezoidal fan blades and anti trapezoidal fan blades are two common fan blade designs, which have significant differences in performance and application scenarios. 1. Fan blade shape and heat dissipation efficiency Anti trapezoidal fan blade Shape characteristics: The design of anti trapezoidal fan blades is opposite to that of trapezoids, with their edges facing towards the center of the fan and usually having a smaller thrust. Heat dissipation effect: Anti trapezoidal fan blades produce low noise when generating air volume, making them suitable for environments with high noise requirements. Although its wind pressure is relatively low, it performs well in terms of low noise and stability, making it suitable for low-power devices such as ordinary desktop computers and laptops. Trapezoidal fan blade Shape characteristics: The design of trapezoidal fan blades enables them to generate significant thrust during rotation, making them suitable for applications that require high wind pressure. They are typically able to provide stronger wind pressure at high speeds, making them suitable for devices with high-performance heat dissipation requirements. Heat dissipation effect: Due to its shape, trapezoidal fan blades can effectively push air and usually generate high wind pressure, but correspondingly, the noise is also high. This makes it perform well under high load conditions, but it may not be as effective in noise control as other shaped blades. 2. Noise effect Inverted trapezoidal fan blade: This type of fan blade design has relatively low noise during operation, making it suitable for noise sensitive applications such as office environments or home use. Trapezoidal fan blades: Due to their shape and design, trapezoidal fan blades typically produce significant noise during operation, especially at high speeds. This makes them less suitable for situations that require a quiet environment. 3. Fan blade shape and application scenarios Trapezoidal fan blades: suitable for high-performance computers, servers, and other devices that require high heat dissipation efficiency. Inverted trapezoidal fan blades: More commonly found in low-power devices such as regular desktop computers and laptops, suitable for occasions with higher noise requirements. Suggestions for choosing the shape of fan blades When choosing a cooling fan, the use of trapezoidal or anti trapezoidal blades should be determined based on specific cooling and environmental requirements. If efficient heat dissipation is required and noise is not a major concern, trapezoidal fan blades are a better choice; If there are strict requirements for noise, trapezoidal fan blades are more suitable.
