Information
The DC cooling fan is a kind of heat dissipating device that converts electric energy into machinery and drives the blades to rotate through DC voltage and electromagnetic induction. It has many advantages such as good heat dissipation effect, fast speed and long service life. So everyone has to understand how the DC cooling fan works? Here is a brief introduction to everyone.
 
Running steps of the DC cooling fan:
 
1. The DC cooling fan is mainly composed of a rotor, a stator, a fan blade and other auxiliary components (such as bearings/rings, etc.). There should be many semiconductor components in the control circuit, which are now stored in one or more ICs. Some manufacturers have specially designed and manufactured many models to control the motor IC to supply the fan circuit. However, different types of IC control circuits are different, but their main purpose is to provide effective function of the coil and related characteristics of the DC cooling fan for more effective control and protection.
 
2. The speed signal output from the DC cooling fan circuit is usually in the form of a pulse. Each wave head indicates that the fan has rotated one turn. Such a signal can be directly provided to the host for display through the data bus. The speed signal output by some DC cooling fans is not the actual speed of the fan, but a multiple of the speed. For example, two, four or six pulses are generated per revolution, so it must be processed to form a true speed signal reflecting the fan. To tell if the speed is a true speed or a multiple, use the tachometer to measure the actual speed and compare it to the displayed data.
 
3. The monitoring mode of the DC cooling fan itself has two types: alarm sensor and speed sensor. The alarm sensor can provide an alarm signal when the fan speed is lower than a certain threshold, and the speed signal output can realize the real-time fan speed. monitor. It can be seen that the larger the airflow, the higher the heat dissipation capability of the DC cooling fan. This is because the heat capacity ratio of the air is constant, and the larger air volume, that is, more air per unit time can carry more heat, and the heat dissipation effect is related to the flow mode of the wind in the same air volume.
