Talking about the future development direction and trend of cooling fans

The cooling fan is a new type of mechatronics fan that uses the principle of electromagnetic induction and uses the Hall induction component as a synchronous detection device to control a set of circuits, switch the order of winding energization, generate a rotating magnetic field, and realize electronic commutation. The cooling fan has obvious advantages in terms of wide speed regulation range, light weight, environmental protection and energy saving, controllability, reliability, environmental tolerance and economy. It gradually replaces other types of motors in the field of high performance and dominates status.

The cooling fan is powered by direct current. The DC motor consists of two parts: the stator and the rotor. There are magnetic poles (winding type or permanent magnet type) on the stator, and the rotor has windings. After the staff energizes it, a magnetic field (magnetic pole) is also formed on the rotor. There is an angle between the magnetic poles of the stator and the rotor. Under the mutual attraction of the magnetic field (between the N pole and the S pole), the motor rotates.

The cooling fan technician told us that by changing the position of the brush, the angle between the magnetic poles of the stator and the rotor can be changed (assuming that the magnetic pole of the stator starts from the angle, the magnetic pole of the rotor is on the other side, and the magnetic pole of the rotor points to the magnetic pole of the stator. The direction is the direction of the rotation of the motor), after this operation, the rotation direction of the motor can be changed.

Let's talk about the development direction and trend of cooling fans in the future. Twenty years ago, cooling fan manufacturers were basically made by Taiwan factories or Japanese factories. There are almost no manufacturers in mainland China. Twenty years later, Taiwanese brands are good, Japanese brands are good, and there are only a few listed companies. They have a good market share at the top due to their product design advantages. Now, almost all the low-end market is done by cooling fan manufacturers in mainland China. In the past 20 years, the development of cooling fans can be said to be very rapid.

Ten years ago, I worked in a Taiwanese factory. At that time, the Continental fan factory started production. Both the mold quality and the fan quality are very different from the second-tier factories in Taiwan. It's not a cooling fan. The balance is not good, that is, the fan does not rotate for a long time, and the plastic mold is very rough. I must be in awe of the Chinese, take my work seriously, explore technology, learn from copying, learn from innovation, and catch up with the curve. After more than ten years of hard work and learning, mainland China's cooling fans not only surpass Taiwan's second-tier companies in quality, but also have many designs that are close to first-class brands. The only things that are relatively weak are the design of the duct and the shape of the blades. We are building on our experience to make up for this weakness. We also summed up the standard for floor cooling fans.

The future development direction and trend of cooling fans are analyzed as follows:

From the characteristics of cooling fan demand, it is guessed that for small and medium-sized cooling fans with a large amount of use, the product structure and manufacturing process are relatively simple, and the cost is also low. What users first seek is high efficiency, low noise, long life, and low price. The other is capital and skill-intensive, the product structure is messy, the production cycle is long, the complete set and system are also strong, and it works under high pressure, high temperature and high speed conditions, and some even work under harsh conditions. Different types of cooling fans have different requirements. For the performance of the cooling fan and the brand required by the large industrial cooling fan, and the first thing that users seek is the cooling fan of high quality, high reliability, stable operation and long cycle.

According to the demand structure of the main category, it is estimated that general ventilation and ventilation cooling fans (usually small and medium centrifugal fans and axial flow cooling fans) are the most widely used, have the largest demand, and have many manufacturers. Generally speaking, the delivery time of cooling fans is longer, because this type of products is in short supply. Especially cooling fans (including AC fans, DC fans, centrifugal fans cooling fans, axial fans, double reverse cooling fans, etc.) are now in increasing demand for such products. I firmly believe that cooling fans will go further and further in the future. Development is inseparable from cooling fans.

In the future, the development direction of cooling fans must be multi-field and extensive. In recent years, there are more and more manufacturers and agents producing cooling fans, which shows that cooling fans will gradually become a trend in the future. And our industrial fan network is gradually building such a portal network, integrating many products, one-stop solution to all your needs
