[Do you know about heat dissipation] How to extend the service life of the cooling fan?

Release time:

2019-06-05

As the name suggests, the cooling fan is mainly used for heat dissipation and cooling of various equipment. It is mainly used in industry. The general industrial environment is more complicated, so it is often necessary to do some treatment on the cooling fan to avoid corrosion. This is also to extend The life of the equipment reduces costs. What is the main work? 1, cooling fan surface treatment cooling fan surface protection treatment, usually using galvanized, chrome plating, chemical plating and other methods. These methods are effective in many environments, but for rotating parts, you need to choose carefully, because the base material and coating are two kinds of materials, the coefficient of linear expansion

As the name implies, the cooling fan is mainly used to do heat dissipation and cooling work for various equipment. It is mainly used in industry. The general industrial environment is more complicated, so it is often necessaryCooling fanDo some treatment to avoid corrosion, this is also to extend the life of the equipment and reduce costs. What is the main work?
1. Surface treatment of cooling fan
The surface protection treatment of the cooling fan is usually carried out by zinc plating, chrome plating, chemical plating and other methods. These methods are effective in many environments, but for rotating parts, it is necessary to choose carefully, because the base material and the coating are two materials, and their linear expansion coefficients are different, which will produce different elastic deformation of the rotating parts. The amount of deformation, resulting in a large number of microcracks, which will accelerate the formation of corrosion. Therefore, we need to choose 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. The structural design of the cooling fan, the most easy to accelerate the corrosion of the design defects is the stress concentration tendency and the crevice environment, sometimes although the metal immersion solution, the corrosion rate is small; but the formation of the crevice, due to the chemical and electrochemical state of the internal solution has changed, Will cause serious crevice corrosion, the need for 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 part material is determined from the fundamentals. From the point of view of the material itself, the target material it targets is safe.
