An important cooling equipment of modern industrial machinery is called
DC cooling fan, It has many characteristics such as good heat dissipation effect, long service life, simple structure, convenient installation, etc., and is widely used in mechanical heat dissipation. so you know what is dc cooling fan?
The DC cooling fan is mainly composed of a rotor, a stator, a fan blade and other auxiliary components. There should be many semiconductor components in the control circuit, which are now stored in one or more ICs. Many manufacturers have specially designed and manufactured many models of control motor ICs for fan circuit design and use. Different types of IC control circuits are different, but the main purpose is to provide effective functions of coils and fan-related characteristic requirements for more effective control and protection.
DC cooling fan
The working principle of: Through DC voltage and electromagnetic induction, electric energy is converted into machinery to drive the fan blades to rotate. Simply put, it relies on the coil and IC to continuously switch, and the induction magnetic ring drives the fan blades to rotate from the heat dissipation device.
Advantages of DC cooling fan:
1. The DC cooling fan adopts the most advanced design, which has the characteristics of large air volume, low noise, long life and corrosion resistance.
2, the use of high-quality bearings, silicon steel sheet, enameled wire, with higher reliability.
The monitoring methods of DC cooling fan itself are:
There are two types of monitoring methods for the DC cooling fan: alarm sensor and speed sensor. The alarm sensor can give an alarm signal when the fan speed is lower than a certain threshold, and the speed signal output can realize the real-time monitoring of the fan speed. Obviously, the greater the air volume, the higher the heat dissipation capacity of the DC cooling fan. This is because the heat capacity ratio of air is certain, and more air volume, that is, more air per unit time, can take away more heat.
The speed signal output from the DC cooling fan circuit is usually in the form of pulses, and each wave head indicates that the fan has rotated one circle. Such a signal can be directly provided to the host for display through the data bus. The speed signal output by some fans is not the real speed of the fan, but a multiple of the speed. For example, 2, 4 or 6 pulses are generated per revolution, which must be processed to form a real speed signal reflecting the fan.
