How to prevent corrosion of the cooling fan?

Cooling fans are used in industrial production, mainly for heat dissipation, cooling and dust removal for large-scale production equipment. The general industrial production environment is more complicated. In order to prolong its service life, the cooling fan needs some treatment, such as the most common anti-corrosion. Today, the cooling fan manufacturer-Ruiapple will introduce how to prevent corrosion of the cooling fan:

1. Surface treatment of cooling fan

The surface protection treatment of the cooling fan is usually carried out by methods such as zinc plating, chrome plating, and chemical plating. These methods are effective in many environments, but for rotating parts, you need to choose carefully, because the base material and the coating are two materials, and their linear expansion coefficients are different, which will produce different results when the rotating part is elastically deformed. The amount of deformation, resulting in a large number of micro-cracks, will accelerate the formation of corrosion. Therefore, we need to select appropriate materials and processes according to the actual use environment.

2. Cooling fan design

The design of the cooling fan is the performance of its core technology, which affects the service life of the fan and ensures the safety of the fan. In the structural design of the cooling fan, the design defects that are most likely to accelerate corrosion are the stress concentration tendency and the crevice environment. Sometimes although the corrosion rate is small in the metal immersion solution, the gap is formed. Due to the changes in the chemical and electrochemical state of the internal solution, It will cause severe crevice corrosion and requires careful design.

3. Material of cooling fan

The materials used for different cooling fans are different, and the anti-corrosion effect is also different. After selecting the cooling fan model, according to the corrosion resistance of different materials in different environments, the main application environment, working strength and many other factors, the strength parts materials are determined from the fundamentals. From the perspective of the material itself, the target material it targets is safe.
