DC cooling fanIt is a kind of heat dissipation equipment, which has the characteristics of good heat dissipation effect, fast speed, and long service life. It converts electrical energy into machinery through DC voltage and electromagnetic induction, thereby driving the blades to rotate. So, do you know how the DC cooling fan works? The following is a brief description of the editor. In the auxiliary conductor, a DC conductor is required for heat dissipation. The cooling fan or fans shall be designed as DC fans. DC fans shall be composed of rotor, stator and other auxiliary components (such as bearings/retaining rings, etc.). There should be many halves in the control circuit. Now they have been stored in a DC conductor and heat dissipation step, many control motor ICs designed and used by some manufacturers specifically for fan circuit suppliers. However, different types of IC control circuit is different, but its main purpose is to provide coil function and directly related characteristics for more effective control and protection. The speed signal is directly provided from the data bus to the host. The speed signal output by some DC cooling fans is not the true speed of the fan, but the number of speeds. For example, four or six pulses are generated per revolution, so they must be processed to form a true signal that reflects the fan. If you want to distinguish whether its speed is the real speed or a certain number, you can use the speed to measure the actual speed, and you can use the speed to measure the actual speed. 2. True speed of DC cooling fan. 2. The DC cooling fan has two types of DC cooling sensor and sensor. When the speed of the fan is lower than the alarm sensor, the alarm sensor is used to give the alarm sensor. When the fan output is limited, the true speed of the fan. It can be seen that the greater the air volume, the higher the sensing capability of the DC cooling fan. This is because the heat capacity ratio of air is certain, and the air volume is larger, that is, more air per unit time can take away more heat. The same air volume is related to the way the wind flows.
Application advantages of DC cooling fan:
1. Good speed regulation performance. Control is simple. Optimum efficient fan blade design. Ultra high air volume, high torque motor design. 2. DC cooling fan wind pressure. Large air volume, long service life, low noise and good operation stability. 3. The inverter has low cost and low inverter capacity. High power factor, low loss and high efficiency. 4. High-quality bearings, silicon steel sheet, enameled wire, higher reliability.
Here first introduce the operation mode and advantages of the DC cooling fan. DC cooling fans have many advantages. The above points are recognized by you during use.
We are buying cooling fans. If there is no introduction from a friend, we usually look for a supplier of DC fans through the Internet. Since there are many specifications of DC fans, each customer has different conditions of use. The parameters are different. Many manufacturers do not produce inventory, and only few have inventory like Jiangshan. Therefore, when buying a cooling fan, it is recommended to choose a strong manufacturer to ensure quality and after-sales service.
