In the modern era of science and technology, the popularization and use of electronic equipment inevitably brings about the problem of electromagnetic interference. Especially in the use of cooling fans, traditional brushed fans often produce electromagnetic interference, which brings inconvenience to users. This time brushless cooling fan is your best choice. How does it reduce electromagnetic interference? Mainly through four ways:

Use an electronic controller instead of a mechanical commutator: Just like our A17051A industrial high-speed axial flow brushless cooling power cabinet fan uses an electronic controller instead of the mechanical commutator of the traditional brushed cooling fan. In this way, electromagnetic interference caused by mechanical friction can be reduced, while the electronic controller can precisely control the speed and current of the motor, thereby reducing electromagnetic radiation.

Ground and grounding: Some wholesale 24v DC brushless fans will also improve the ground and ground, good grounding can reduce electromagnetic radiation and interference. Ensure that the ground cables of the brushless cooling fan are securely connected to the grounding system of the entire system.

Want a breath of fresh air? Choose a centrifugal fan with an air purifier! It's a winning combination, and let's see why.

First of all, the centrifugal fan can produce a high static pressure capacity during the rotation process, our centrifugal fan usually includes a rotating impeller and a spiral guide housing. This design can collect air in the center and spray it at a higher speed under the action of centrifugal force, resulting in a larger static pressure. This means that it can effectively capture and remove harmful substances such as particles, formaldehyde, and odors in the air to ensure the purity of indoor air.

Secondly, the application of centrifugal fans in air purifiers is also reflected in its silent performance. Some special designs of the blades of centrifugal fans will reduce the production of noise, just like our centrifugal fans usually use smooth blade curves to reduce the production of noise when the air flows. In some specific cases, we will also reduce the noise level of the centrifugal fan by increasing the number of blades, more blades can make the noise more easily isolated and dissipated. Noise is reduced, thus improving the user experience of the air purifier.

Our 12v centrifugal fan is a combination of the above two points, in addition to this fan, there are other fans you can choose, such as plastic centrifugal fans, brushless centrifugal fans, we are also a good choice for wholesale air centrifugal fans.

Then the last part continues to discuss the important influence of blade material on the performance of the cooling fan.

(1) Blade material

Plastic blade:They are lightweight, low in manufacturing cost and can be quickly produced by injection molding. However, plastic blades generally produce more noise than other materials and may have lower strength and durability.

Fibrous composite material:It has good strength and durability, can provide lower noise and higher airflow efficiency, can improve the efficiency and output power of the fan.

Aluminium alloy:It is a commonly used blade material, with high strength, light weight and easy processing characteristics. Aluminum alloy has good thermal conductivity, can effectively dissipate heat, and improve the heat dissipation effect of the fan. The blades of our AC-F60300 air radiator cross flow fan are made of high-quality aluminum alloy metal material, which is not easy to deform, well-made, strong and durable frame, and long service life. In addition, the working temperature of the air radiator cross-flow fan is -10℃ ~ 70℃ ultra-high temperature range, aluminum structure, waterproof function is strong, suitable for most outdoor environments, this waterproof moisture-proof AC cross-flow cooling fan is especially suitable for outdoor advertising display heat dissipation.

Let's pick up where we left off in the last blog post.

Multiple small fans:

· Balanced heat dissipation: Multiple small fans can better cover the entire computer interior, bringing cool air to several key components. This can effectively solve the hot spot problem and temperature imbalance.

·Flexibility: Since multiple small fans can be controlled independently, you can adjust the speed and operating mode of each fan as needed to meet specific heat dissipation requirements.

However, there are some disadvantages to having multiple small fans:

·Noise and energy efficiency: The total noise generated by multiple fans can be higher than a single large fan. In addition, they use a lot more power than a large fan.

In the end, there are pros and cons to both options, and choosing a single large fan or multiple small fans depends on your specific needs and system requirements.

Cooling fans are an indispensable component of modern computers, electronic equipment and automobiles. In order to improve heat dissipation and performance, we are constantly looking for innovation and development. This paper will discuss the important effects of motor and blade materials on the performance of cooling fans.

 （1）Motor materials

Steel：It has the characteristics of high magnetic conductivity, low loss and easy processing, so that the motor can maintain a high frequency during operation. However, the disadvantage is that the density of steel is large, and it is easy to produce hysteresis loss.

Carbon fiber: It’s suitable for high-speed, high-efficiency motors. Carbon fiber has the advantages of high magnetic conductivity, high strength and light weight, which can improve the efficiency and output power of the motor. The only drawback is the high price.

Copper: It’s an excellent conductive material and is often used to make coils and conductors in electric motors. Copper has a higher electrical conductivity than aluminum. Our model 6A610 DC brush torque motor is a pure copper wire coil, with high electrical and thermal conductivity, can reduce resistance and heat loss. In addition, the DC brush motor consists of a rotor, stator and brush ring assembly, designed as an integral part of the system, which is even more weight and space saving. As a manufacturer, we strongly recommend this DC brush hollow cup motor for beauty products, remote control toys, electric toothbrushes, USB small fans, smart electronics and other devices. Welcome to purchase needs of everyone to come to consult!

Then the previous article continues to say how the temperature sensing element of the temperature control cooling fan works. Take a dc cross flow fan for example, the fan control circuit will adjust the speed and power of the fan according to the signal from the temperature sensing element. When the temperature exceeds the threshold, the fan will operate at the maximum power to enhance the heat dissipation effect; When the temperature drops to a set range, the speed of the mini cross flow fan will gradually decrease to save energy and maintain a suitable temperature.

Through the working principle of the temperature sensing element, the temperature control cooling fan can automatically adjust the operating speed and power of the fan in time according to the change of the ambient temperature, so as to ensure the best heat dissipation effect of the device, and reduce power consumption and noise.

To sum up, the temperature sensing element plays a key role in the temperature control cooling fan, which can sense the change of the ambient temperature and realize the intelligent adjustment of the fan by transmitting signals to the fan control circuit. This makes the temperature-controlled cooling fan have great advantages in terms of equipment heat dissipation and energy saving, which brings convenience and comfort to our life and work.

The cooling effect of the cooling fan is indeed related to the number of fan blades, but this is only one of the influencing factors. Here's a detailed explanation:

1. Wind pressure

Wind pressure: More blades generally provide higher wind pressure, which is beneficial for cooling scenarios that require high wind pressure.

2. Blade design

Shape and Angle: Optimized blade design allows for better air flow and higher efficiency with a relatively small number of blades.

3. Noise level

Number of blades: More blades can reduce the load on a single blade, thus reducing the speed and reducing noise at the same air volume. However, more blades may also lead to more air disturbance, increasing noise.
