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:
Our company will soon be participating in the following international electronics exhibitions. At these exhibitions, we will showcase a range of DC fans, DC blowers, boosted-pressure fans, waterproof and dustproof fans, and miniature fan lights—demonstrating our strength as a professional fan manufacturer. We also warmly welcome both new and existing customers to visit our booth. The booth information is as follows:
Recently, Jiangshan Lai welcomed Mr. Paulo, a customer from Brazil, and paid a visit to our company’s factory. Two colleagues from our foreign trade department, Phoebe and Bryant, extended a warm welcome to him.

DC cooling fans are widely used in our daily lives and can be found in numerous industries, including telecommunications equipment, air purifiers, UPS power supplies, medical devices, and more. They have extensive applications and a huge market size.
The day before the Mid-Autumn Festival on September 12, our company organized a dinner gathering for all employees. On this special occasion of the Mid-Autumn Festival, members of the Jiangshan Lai big family gathered together at the Xiang Furong Restaurant, where we raised our glasses and enjoyed each other’s company, celebrating together! The development of Jiangshan Lai would not have been possible without everyone’s hard work. This dinner brought us closer together, truly demonstrating that Jiangshan Lai is one big family—and we’re all part of it. We’re all members of a family that supports and helps one another.
“Cooling fans” are surely familiar to everyone—whether it’s inside computers, water dispensers, refrigerators, air conditioners, air purifiers, cars, or countless other devices, you’ll find them everywhere. However, the term “cooling fan” is merely a generic umbrella term for all types of fans. So how much do you really know about the specific classifications of cooling fans? At the most basic level, cooling fans can be categorized according to their power supply: those powered by DC are called DC cooling fans, while those powered by AC are called AC cooling fans. These are the fundamentals, and I’m sure most of you already know about them. Today, though, I’d like to focus on another classification—namely, the different directions of airflow they employ. Broadly speaking, there are four main categories:
Cooling fans are widely used in industrial production, primarily for cooling, temperature reduction, and dust removal in large-scale production equipment. Given that typical industrial environments are often quite complex, to extend the service life of cooling fans, it’s essential to perform certain treatments—such as the most common one: corrosion prevention. For instance, what causes cooling fans to leak or splash oil? Today, we’ll show you how to prevent corrosion in cooling fans.
