How to choose a cooling fan better?

As we all know, the function of the cooling fan is very critical, especially in high temperature environments such as summer, it is even more difficult to withstand high temperatures. Therefore, it is particularly necessary to choose an efficient cooling fan. However, as the demand for cooling fans continues to increase, more and more manufacturers are producing various cooling fans. Do you know how to choose a cooling fan? Today, Ruiapple will introduce how to choose a cooling fan.

1. When choosing a cooling fan, people often compare wind pressure and air volume. For normal ventilation, during the ventilation stroke, the wind pressure and air volume need to overcome the resistance of the cooling fan. The cooling fan must generate pressure to overcome air supply resistance. It is wind pressure. The wind pressure mainly depends on the shape, area, height and speed of the fan blades. The faster the speed, the larger the fan blades. The higher the wind pressure, the radiator with the air duct design can better maintain the wind pressure of the cooling fan.

2. In terms of design, in addition to the above-mentioned general design, some cooling fans also adopt some very special designs. Through the application of newer technologies and processes, they can better meet the needs of users. The cooling fan is dust-proof, and all airflow during long-term use will be covered by thick dust. This will cause poor air circulation. Increase the weight of the blade. Reduce the speed or increase the motor load, or even damage the fan.

3. The total amount of air sent or sucked in by the cooling fan every minute. When the material of the radiator is the same, the air volume is the most important indicator to measure the heat dissipation capacity of the air-cooled radiator, that is, the larger the fan, the greater the air volume. Therefore, a larger air volume can take away more heat per unit time. If the wind volume is compared with the swing force of the weapon, the wind pressure is the sharpness of the weapon. When other conditions remain unchanged, the actual air volume plays a decisive role in the role of the cooling fan.

4. When choosing a cooling fan, what we need to know is that the more vertical the fan blades of the cooling fan, the larger the windshield area, the greater the air volume generated, and the greater the windshield noise. Not to mention heat dissipation. The number of blades and blade design will also have a great impact on air volume and pressure. The design of the cooling fan blade has a more obvious impact on the performance of the fan. At the same speed, products with excellent fan blade design can provide greater air pressure and air volume, resulting in better heat dissipation.

I believe that after the above introduction, everyone has an understanding of how to better choose a cooling fan. If you have any questions, please consult Ruiapple.
