DC cooling fan Fan blade types are generally classified according to the shape of the blades, since the blade shape directly determines the performance characteristics of the fan. Fan blades are typically categorized into fine right angles, coarse angles, and fine angles. It would be somewhat far-fetched to describe turbine fans as a separate type of fan blade.
The slim, right-angle blade is the earliest product, yet it remains timeless to this day. Fans equipped with these DC blades excel only in terms of noise level, air pressure, airflow volume, and service life, making them suitable for low-heat applications.
Thick, curved fan blades offer the best cooling performance because they generate high wind pressure and sufficient airflow, which also help accelerate the rate of heat exchange. However, thicker curved blades tend to produce more noise, exert greater centrifugal forces on the shaft during rotation, and suffer more severe wear, thereby shortening their service life to some extent. These types of fan blades are typically used in high-volume, high-performance fans that require greater airflow.
The curved-blade fan is an improved version of the thick curved-blade fan. It features a greater number of blades, ensuring a sufficient airflow for DC cooling fans. Moreover, thanks to its lightweight blades, high rotational speed, and even rotation, this fan produces relatively low noise levels. However, the biggest drawback of the thin curved blades is their slightly lower air pressure, leaving a slight sense of regret among users.

Advantages and Applications of Oil-Bearing DC Fans
The pivot joint is fixed at the position of the motor stator base, ensuring an appropriate gap between the rotor and the stator. Of course, there must also be a clearance between the shaft core and the bearings to prevent the shaft core from becoming locked and thus unable to function. The stator structure of the motor—hereafter referred to as the "stator"—is designed in such a way that, once power is supplied, an induced magnetic field will be generated between the rotor and the stator. The control circuit then drives the electric fan motor into operation. Therefore, in the conventional fan motor design, as long as the fan rotor, the motor stator, and the drive circuit work together via the pivot joint between the shaft core and the bearings and through magnetic field induction, the motor can operate effectively.
