Do you know how to choose a cooling fan?

As we all know, the function of the cooling fan is very critical, especially in the summer high temperature environment, it is more difficult to withstand high temperatures, so it is necessary to choose an efficient cooling fan. Then, as the demand for cooling fans continues to grow, there are more and more manufacturers and types. Do you know how to choose a cooling fan? let me tell you.

How to choose a cooling fan:

When choosing a cooling fan, the wind pressure and air volume are usually compared. For normal ventilation, wind pressure and air volume need to overcome the resistance in the ventilation stroke of the cooling fan. The pressure generated by the cooling fan to overcome the air supply resistance is the wind pressure. The wind pressure mainly depends on the shape, area, height and speed of the fan blades. Generally, the faster the speed, the larger the fan blades. The higher the wind pressure, the better the air duct design of the radiator can maintain the wind pressure of the fan.

In terms of design, in addition to the above general design, some cooling fans also adopt some very special designs. By applying newer technologies and processes, they can better meet the needs of users.

In addition to the heat dissipation effect, everyone will also pay attention to the working noise of the cooling fan. Since fan noise is the size of the noise generated when the fan is working, it is affected by many factors. The noise of the cooling fan should be measured in an anechoic room where the noise is less than 17dB. The distance to the fan should be one meter, and the air inlet of the fan should be aligned according to the direction of the cooling fan shaft. In addition, the spectral characteristics of cooling fan noise are also very important, so it is necessary to use a spectrum analyzer to record the frequency distribution of fan noise. Generally, the noise of the fan is required to be as small as possible, and no abnormal sound occurs.

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