Many manufacturers suppliers do not choose how to select a DC cooling fan. They are usually just looking for a few manufacturers, and then take samples back. The test can be switched to OK, and then it is to choose a supplier with a cheaper price. Use this as a standard for this standard. In fact, the cooling fan is not only a day to turn, a few years or even decades can maintain the heat dissipation characteristics, no damage, no fade, only to be regarded as a good quality DC cooling fan it? Shenzhen Fengwang electronic professional technicians teach you how to distinguish the quality of DC cooling fan.

DC cooling fan
1. Look at current ------ same speed, same voltage, same air volume. Small current DC cooling fan is better. Because the smaller the current, it means that the fan loss is smaller, that is, the power consumption is small, the main reason for the small power consumption is: <1>. Product magnetic ability is strong <2>. The motor enameled wire loss is good <3>. Copper The high content of D lubricants is high.

2. To listen to noise ------ DC cooling fans with the same speed, the same voltage, and less noise are better, because the low noise is mainly related to the blades, bearings, oil products, assembly structure and so on. <1> The better the design of the blade shape, the greater the air volume will be, and the lower the noise, this is a technical activity, but also test the ability of technical personnel. <2> The higher the bearing accuracy, the less friction it has with the shaft, the more precise the size, and the lower the noise, which is closely related to the material of the bearing. <3> When the noise is low, it means that the friction is small, the life of the bearing and the shaft core is longer, and the life of the DC fan is also longer.

3. Measure vibration – fans with the same specifications and speed, small vibration DC cooling fan is better, DC cooling fan, is a high-speed parts, vibration must be there, no one can guarantee No vibration, if there are manufacturers to tell you that their products do not vibrate, it is used to deceive ghosts, do not believe that the smaller the vibration, the better, the smaller the vibration, the more stable the fan operation, the bearing The smaller the loss of the shaft core, the less the volatilization of the oil or the wear of the balls, and the longer the service life.

The above are some methods to determine the quality of DC cooling fan, more professional cooling fan knowledge, please pay attention to Shenzhen Feng Wang electronic cooling fan manufacturers, Shenzhen Feng Wang electronic electronic cooling fan manufacturers, specializing in providing cooling fan, cooling fan, DC cooling fan, DC blower and various specifications of industrial cooling fan customization.
