As the demand for cooling fans continues to increase, more and more manufacturers are producing various cooling fans. Do you know how to choose cooling fans? The following editor will take you to find out.
1. In the selection of the cooling fan, it is necessary to compare the wind pressure and air volume. In order to allow the wind pressure and air volume to ventilate normally, it is necessary to overcome the resistance in the ventilation stroke of the cooling fan. The resistance mentioned here refers to the wind pressure. The wind pressure mainly depends on the shape, area, height and speed of the fan blade. Generally, the faster the speed, the larger the fan blade. When the wind pressure is relatively higher, the air duct design of the heat sink can better maintain the wind pressure of the fan.
2. In terms of design, in addition to the general design of the cooling fan, it is also necessary to apply newer technologies and processes to better meet the needs of users. Because the cooling fan is dust-proof, all parts of the airflow through long-term use will be covered with a thick layer of dust, which will cause poor airflow, increase the weight of the blades, reduce the speed or increase the motor load, and cause damage to the fan. .
The above is the explanation on the selection of the cooling fan, I hope it will be helpful to you.
