What are the misconceptions when choosing a DC cooling fan?

1. Only imported DC cooling fans are high-quality products, while domestic DC cooling fans are low-end products

At present, China's industrial production level is slightly behind that of Japan and Germany, but some of China's cooling fans can still compete with imported brands. Some well-known brands in China have been producing in this industry for many years, and the technical level of DC cooling fans is not lagging behind foreign countries. They also have an advantage in terms of price, which is much higher than before. However, most domestic manufacturers still remain at the level of low-end machines.

They also have an advantage in terms of price, which is much higher than before. However, most domestic manufacturers still remain at the level of low-end machines. 2. Fans are consumables, just choose cheaper ones

Many manufacturers directly position cooling fans as anti-static consumables and replace them every six months or annually. Meanwhile, procurement costs remain at a very low level. The cheaper, the more I like it. In fact, this has entered an infinite cycle. Frequent replacement does not reduce costs. Strictly speaking, cooling fans are not consumables. This is a small supporting equipment. Its service life is determined by the on-site environment, frequency, and quality of the cooling fan. The environment and frequency cannot be changed, so the quality of the cooling fan is very important. Good quality and long service life. Of course, the price will be higher.

3. Direct use of DC cooling fan without inspection and maintenance

Many manufacturers consider DC cooling fans to be blowing fans when producing equipment. In fact, this is a very irresponsible approach. The function of a DC cooling fan is to prevent the occurrence of electrostatic discharge. The impact of static electricity on products, although invisible to the naked eye, may not necessarily have an impact, so it is easy to overlook. But once ESD occurs, the defect rate of the product will increase, and even there will be high quality hazards, which are not worth the loss. In addition, the cooling fan needs regular maintenance, as prolonged discharge in the ionization device can lead to dust oxidation and adsorption, and weaken ion release. There are maintenance free cooling fans on the market now, and cleaning times can be freely set. In general, the cooling fan should be sampled monthly or quarterly according to the factory conditions to ensure effective use.

4. The DC cooling fan is a high-voltage discharge module, which is the same as any manufacturer

Many companies make this mistake. Of course, this cannot be blamed. After all, in some enterprises, the consumption of DC cooling fans can be ignored, and the procurement cost can also be ignored. In addition, buyers are not technical personnel and may not have much knowledge of the product. They believe that DC cooling fans are the same and there is no difference. In fact, this is not the case. Just as some people believe that mobile phone assembly factories only need to purchase all the accessories such as screens, soft boards, cameras, casings, batteries, antennas, etc. to produce finished machines, there are many ways for DC cooling fans, and there are many different brands. There are also significant differences, such as how much high voltage is required for discharge, how many positive and negative ions are required to ensure no reverse charging, etc. Not all manufacturers can achieve this.

When purchasing fans, enterprises should not only pay attention to price and quality, but also pay attention to after-sales service. Although imported fans have good quality, after-sales service may not keep up. For such equipment, manufacturers need to arrange technical personnel for on-site spot checks every year. If the cooling fan malfunctions, the production line will shut down, causing production
