Fan anti-salt spray structure and its fan frame

Abstract

The invention relates to a fan salt spray proofing structure and a fan frame with the structure. The fan salt spray proofing structure comprises a base and at least one flow guide protrusion; the base is perpendicularly provided with a beam barrel, and the base extends outwards to form a plurality of connecting bodies; and the flow guide protrusions are arranged at the connecting positions of the base and the connecting bodies. In addition, the fan frame is provided with a body, and the body is provided with a first open side and a second open side; and a flow way is jointly defined by the first open side and the second open side. One end of each connecting body is connected with the second open end of the corresponding body; through arrangement of the flow guide protrusions, deposition crystallization caused by the vortex formed by flowing of airflow containing moisture and salt spray through the base and the connecting bodies can be avoided; and the service life of a fan is greatly prolonged.

Problems solved by technology

[0002] With the continuous expansion of the application field of cooling fans, from the CPU, server, power supply, communication chassis, telecommunication base station, etc. in electronic equipment, the environment in which the fan is used is becoming more and more severe; In the environment, when the fan is running, a vortex will be formed at the bottom of the fan frame after the wind flows through the fan blades and the hub. If the fan is placed in a harsh environment, crystallization may occur between the hub and the fan blades. The structure is protected from water vapor and salt spray intrusion, so when the internal stator and bearings are invaded by water vapor and salt spray, they will be rusted, and the circuit board will be corroded and damaged, so the life of the fan will be shortened

[0003] The current cooling fan is mainly composed of stator, rotor, circuit board, fan blade body and fan frame and other components, and in order for the fan to operate normally in the aforementioned harsh environment, it is necessary to prevent salt spray and water vapor from corroding the inside of the fan. Structure, in the prior art, in order to prevent water vapor and salt mist from corroding the internal stator and circuit board of the fan and causing damage to the fan, the aforementioned stator group and circuit board are glued to the outside of the stator group and circuit board The complete coating is used to prevent water vapor and salt spray from damaging the stator group and circuit board; however, although the aforementioned glue sealing method is effective to prevent water vapor and salt spray, it is easy to prevent heat dissipation after the stator group and circuit board are completely sealed and operated. The phenomenon of heat accumulation; so the prior art has the following disadvantages:

[0004] 1. Short life;

[0005] 2. The inside of the fan is easy to accumulate heat;

[0006] 3. Low cooling efficiency
