Description

Technical Field

[0001] The utility model belongs to the technical field of cooling fans, and particularly relates to a protection device for a fan stator. Background Art

[0002] In electronic devices, cooling fans are key components for heat dissipation. However, during operation, the stator of a cooling fan is prone to being affected by environmental factors such as dust accumulation, moisture intrusion, and corrosion by corrosive gases. These factors can lead to a decline in the performance of the cooling fan or even damage. Existing protection measures often cannot comprehensively and effectively solve these problems, so a new type of protection device is needed to improve the protection effect of the cooling fan stator.

[0003] There are mainly two most commonly used stator protection methods in the prior art. One is coating, and the other is potting. The stator coating process is to coat a layer of film on the surface of the stator, and potting is to encapsulate the whole stator with a layer of glue. These two methods have defects such as high cost, low production efficiency, and complex processes. Summary of the Utility Model

[0004] The utility model provides a protection device for a fan stator to solve the deficiencies in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The protection device for a fan stator includes:

[0007] A fan frame, in which a stator installation part is provided. Outside the stator installation part, there is a baffle part. There is a notch on the baffle part. Inside the notch, there are a first protrusion part and a second protrusion part. A wire slot is provided between the first protrusion part and the second protrusion part;

[0008] A stator, sleeved on the stator installation part; and

[0009] A protective sleeve, sleeved on the stator and the outer edge of the protective sleeve abuts against the inner wall of the baffle part. On one side of the upper bottom of the protective sleeve, there is a protruding part, and the protruding part is adapted to the notch. The outer walls of the first protrusion part and the second protrusion part are in contact with the protective sleeve. The lead wire of the stator passes through the wire slot and the protruding part of the protective sleeve and extends to the outside of the fan frame. The upper side of the stator installation part extends into the upper part of the protective sleeve.

[0010] By adopting the above technical solutions, the utility model has the following beneficial effects:

[0011] The utility model adopts a combination of a protective sleeve, a stator and a fan frame. The protective sleeve can sleeved the stator and provide protection, and the protective sleeve also has a protruding part that is clamped in the notch, realizing all-round protection, effectively preventing pollutants from entering the stator, improving the protection performance, extending the service life of the fan, being easy to operate, improving the production efficiency, reducing the production cost, and having high reliability;

[0012] In summary, the utility model has the advantages of high production efficiency, low cost, high reliability, easy operation, good protection performance, long service life, etc. Brief Description of the Drawings
