With the development of society, people's requirements for air quality are getting higher and higher, and the air purifier industry has also developed, and the cooling fan that is a good partner of air purifiers has also developed.

Air purifier is a common electrical appliance in people's homes, which is frequently used and easily worn out. In order to prolong the service life of the purifier, a cooling fan is usually installed inside to effectively reduce the operating temperature of the purifier. Then the design of the air purifiers cooling fan must have certain requirements.

In design, in addition to the general design, the air purifier cooling fan can better meet the needs of users through the application of newer technologies and processes. In terms of dust prevention, after long-term use of axial cooling fan, various parts of the air flow will be covered with a thick layer of dust, which will cause poor air flow, increase the weight of the blades, thus reducing the speed or increasing the motor load, and even causing fan damage.

Then, when selecting the cooling fan of the air purifier, what we need to know is that the more vertical the fan blades of the cooling fan, the larger the wind cut surface, the greater the airflow generated, and the greater the wind cutting noise; On the contrary, if flat blades are used, there will be less wind, or even no wind, which leads to ineffective heat dissipation. Moreover, the number of blades and the design of the blades will also have a great impact on the airflow and pressure. The design of the ventilation cooling fan blades has a more obvious impact on the performance of a fan. At the same speed, products with excellent fan blade design can provide greater pressure and airflow, thereby bringing better heat dissipation effects.
