Industry Trends
Air purifiers are a common household appliance. The more frequently they’re used, the greater the wear and tear on their internal cooling fans. To extend the lifespan of the air purifier, it’s essential to equip it with a cooling fan that helps keep its operating temperature lower during use. Next, let’s take a closer look at its design principle: In terms of design, air purifiers leverage cutting-edge technologies and manufacturing processes to better meet users’ needs. Over time, as the cooling fan operates continuously, layers of dust accumulate in various parts through which airflow passes, leading to obstructed air flow. Adding extra weight to the blades, reducing the rotational speed, or increasing the motor load can even result in electrical issues.
As society continues to develop and progress, people’s demands for air quality are steadily increasing, driving the growth of the air industry. As a result, air purifiers have become indispensable household appliances in many homes. Consequently, their ideal partner—the cooling fan—has also evolved, with demand growing ever higher. Let’s take a closer look at why cooling fans are such a great match for air purifiers, making them perfect partners! Air purifiers are common household appliances that are used frequently, leading to significant internal wear and tear and consequently shortening their lifespan. To extend the service life of an air purifier, it’s essential to equip it with a cooling fan.
The faster a cooling fan spins, the better its cooling performance will certainly be. However, after using a fan for some time, you may notice that its rotation speed gradually slows down and it becomes noticeably louder—almost as if it’s suffering from asthma. What could be causing this, and how can you fix it?

As a type of electronic component that never degrades, the market for cooling fans is teeming with manufacturers—and naturally, the quality of these fans varies widely. We all know that industrial production relies on a wide variety of equipment, and when such equipment operates continuously over long periods, it tends to generate heat. That’s precisely when cooling fans come into play—providing essential cooling to keep equipment running smoothly and in optimal condition. If the equipment isn’t cooled down promptly, internal components could get damaged, disrupting production processes. This clearly underscores the critical importance of cooling fans in industrial manufacturing. Therefore, every enterprise strives to acquire high-performance, high-quality cooling fans. So, how can we fundamentally improve the quality of cooling fans?
Depending on the changing application environments, cooling fans can be categorized by voltage into DC cooling fans and AC cooling fans. Recently, EC cooling fans—derived from the AC type—have also become widely used. Cooling fans find applications in various industries, including power electronics, military equipment, home appliances, and mechanical machinery. Let’s take a closer look at the structures of industrial cooling fans—DC/AC, DC, and AC cooling fans!
First, blade curvature: Within a certain range, the greater the blade curvature of a DC fan, the higher the kinetic energy of the gas at the same rotational speed—resulting in greater airflow and higher static pressure. At the same time, the blades experience greater drag, which in turn requires a higher torque from the motor. Second, motor diameter: Due to the presence of the motor and bearings, the central portion of the DC fan’s main shaft inevitably creates a blind zone where no airflow passes through. The diameter of the main shaft thus determines the size of this blind zone. The smaller the diameter of the main shaft, the more it depends on the power rating of the fan motor—higher-power motors require larger stator winding coils, which naturally occupy more space. If there’s no room for longitudinal expansion (adding...
Generally speaking, proper installation of DC fans can significantly enhance a product’s cooling performance. Factors such as the installation direction, airflow direction, placement location, and distance from the heat-dissipating component all play a crucial role. Even with the same DC fan, different installation methods can lead to vastly different cooling results. To ensure correct DC fan installation, please follow these guidelines:
