    Tips: How does the DC cooling fan prevent corrosion?
    1. DC cooling fan surface treatment
    The surface protection treatment of DC cooling fans is usually performed by galvanizing, chrome plating, chemical plating, etc. These methods are effective in many environments, but for rotating parts, you need to choose carefully, because the base material and the plating are two materials, and the linear expansion coefficients are different, which will produce different results when the rotating parts are elastically deformed. The amount of deformation, which causes the generation of a large number of microcracks, will accelerate the formation of corrosion. Therefore, we need to choose appropriate materials and processes according to the actual use environment.
    2. DC cooling fan design
    The design of the cooling fan is a manifestation of its core technology, which affects the service life of the fan and ensures the safety of the fan. The structural design of the cooling fan, the design flaw that is most likely to accelerate corrosion is the stress concentration tendency and the gap environment. Sometimes, although the corrosion rate is small in the metal immersion solution, the gap is formed because the chemical and electrochemical state of the internal solution has changed. Will cause severe crevice corrosion and needs careful design.
    3. DC cooling fan material
    Different cooling fans use different materials and have different anti-corrosion effects. After selecting the cooling fan model, according to the corrosion resistance of different materials in different environments, the main application environment, working intensity and many other factors, determine the strength of the component materials from the basic plane. From the material itself, the target material it targets is safe.
