Follow up the previous blog to discuss how GPIO reads the fan tach signal

 

4, configure the GPIO pin as the input mode to prepare to read Tach signals. This can be achieved by using appropriate programming languages and libraries. For example, you can use the RPi.GPIO library for Raspberry PI.

5. Read the status of GPIO pin to obtain Tach signal. Depending on the programming language and library you choose, you can use the appropriate function or method to read the GPIO state. If the status changes, the fan speed changes.

 

6, please note that the specific implementation details may vary depending on the hardware platform, fan, and programming language used. Be sure to refer to the relevant hardware and programming documentation for accurate configuration and usage.

It is very important to understand the positive and negative direction of the DC cooling fan, especially during installation and use. Correctly determining the fan rotation direction can effectively improve the heat dissipation effect of the device. The following are some ways to distinguish the positive and negative direction of the DC cooling fan:

Observe the direction of blade rotation: Generally speaking, from the front of the fan, clockwise rotation is positive, counterclockwise is reverse.

Check the markings on the fan: Many fan housings will have arrow markings indicating the airflow and direction of rotation. The air flow following the direction of the arrow is usually positive.

Airflow test: After power, feel the airflow direction of the front or back of the fan, and the airflow blown out of the front is positive, and the reverse is reverse.

5. 92mm x 92mm

Application: For high-end desktops, workstations, servers, etc., need better heat dissipation effect.

Choose the right axial cooling fan to ensure efficient operation and durability of the equipment!

Then the previous article continues to say that the number of fan blades on the effect of heat dissipation factors

 

4. Speed and efficiency

Speed: More blades may require higher speed to provide adequate air flow, which may increase power consumption and wear.

Efficiency: An efficient design can provide good heat dissipation with low power consumption and noise levels.

 

5. Application Scenarios

Dense radiators: High air pressure fans (which typically have more blades) are better suited for scenarios that require high air pressure, such as CPU radiators and water-cooled rows.

Open space cooling: High-volume fans (with a moderate number of blades but optimized design) are better suited to provide good air flow inside the chassis.

Fan mesh cover can be divided into many types according to the different material, structure and use:

Metal mesh cover: Common metal materials are stainless steel, aluminum alloy and so on. This kind of mesh cover is strong and durable, has good protective performance, and is suitable for various industrial environments.

Plastic mesh cover: plastic mesh cover light weight, low price, suitable for some places with low protection requirements. In addition, the plastic mesh cover also has anti-corrosion characteristics, suitable for humid environments.

Electroplating mesh cover: electroplating on the basis of metal mesh cover not only retains the strength of metal mesh cover, but also increases the anti-corrosion ability and extends the service life.

Private network cover for brushless fan: The private network cover designed for brushless ventilation fan can effectively match the high efficiency and long life requirements of brushless motor to improve the overall performance.

When choosing a wholesale air cooler motor, choosing a high-quality mesh cover is also an important factor to ensure the efficient operation of the equipment. By understanding the role and type of fan mesh cover, you can better select and apply the appropriate mesh cover to improve the overall performance and use experience of ventilation equipment. If you have this demand, Chungfo Electronic Technology Co., LTD. air cooler motor wholesale price is also worth your choice!

In computer hardware, the role of cooling fans is very important. However, in the design and installation of cooling fans, the problem of "dead corners" is often ignored. Today, we will delve into the dead corners of cooling fans and how to use advanced motor technology to optimize heat dissipation.

What is the dead Angle of the cooling fan?

The "dead Angle" of the cooling fan refers to those areas that cannot be covered by effective airflow due to design or structural reasons. These areas often have high temperatures, which can easily lead to hardware overheating, affecting the stability and performance of the system.

Common dead corners include the corners of the case, behind the hard drive rack, certain components on the motherboard, near the graphics card, and the top and bottom of the case. Since fan airflow cannot effectively cover these areas, they become a weak link in the cooling system.

The dead Angle of the cooling fan is one of the key factors affecting the heat dissipation efficiency and stability of the equipment. Through reasonable fan layout and the use of advanced motor technology, such as cylindrical micro motor, dc micro brush motor, driving micro motor ,1.2v dc vibrator motor, etc., can effectively reduce the dead Angle, improve the overall heat dissipation performance of the equipment.

I hope this article can help you better understand the dead Angle problem of cooling fans and find an effective solution.

1. Brushless DC Motor (BLDC)

Advantages: The brushless design reduces energy loss and improves overall efficiency. Because there is no brush, the brushless motor has less wear and longer life. Smooth operation and low noise for applications requiring a quiet environment.

Disadvantage：High cost, the manufacturing process is complex, and the cost is higher than that of brushed motors.

Complex control circuits: Additional control circuits are required to manage motor operation.

2. Brush DC Motor (BDC)

Advantages: Simple manufacturing, relatively low cost. No need for complex control circuit, easy to drive directly.

Disadvantages: Brush and commutator wear faster, resulting in shorter life. Due to the contact between the brush and the commutator, the noise generated during operation is larger. High maintenance requirements: brushes need to be replaced regularly, increasing maintenance costs.
