As the name suggests, cooling fans are primarily used to dissipate heat and cool various devices. They are mainly employed in industrial settings, where industrial environments tend to be quite complex, so they often need to be... Cooling fan Take certain measures to prevent corrosion—this is also done to extend the equipment’s lifespan and reduce costs. So, what specific tasks are involved?
1. Surface treatment of the cooling fan
Surface protection treatments for cooling fans typically involve methods such as galvanizing, chrome plating, and chemical coatings. These methods are effective in many environments; however, when applied to rotating parts, careful material selection is essential. This is because the base material and the coating are two different materials with distinct coefficients of linear thermal expansion. As a result, during elastic deformation of the rotating component, the two materials will undergo differing amounts of deformation, leading to the formation of numerous microcracks and accelerating corrosion. Therefore, we need to select appropriate materials and processing techniques based on the actual operating environment.
2. Cooling Fan Design
The design of cooling fans is a key manifestation of their core technology, significantly impacting the fan’s service life and ensuring its operational safety. In terms of structural design, the most common design flaws that accelerate corrosion are stress concentration tendencies and crevice environments. Although in some cases the corrosion rate may be relatively low when metals are immersed in corrosive solutions, the formation of crevices can lead to severe crevice corrosion due to changes in the chemical and electrochemical conditions within the crevices. Therefore, careful design is essential.
3. Material of the cooling fan
The materials used for different cooling fans vary, and so do their anti-corrosion performance. After selecting a specific cooling fan model, the material for structural components should be determined based on fundamental considerations such as the corrosion resistance of various materials in different environments, the primary application environment, and the intensity of operation, among other factors. From the perspective of the material itself, it is safe for the intended target substances.

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.
