AI Technical Summary

Technical Problem

The increased mass of high-power fans causes the gap between the fasteners and the inner wall of the mounting holes to expand, resulting in vibration and making it difficult to maintain the relative stability of the fan and the support.

Method used

The system employs a flow-guiding structure, comprising an inner ring and an outer ring. The outer ring is connected by a first baffle, a second baffle, a connecting bridge, and a first reinforcing part to form a mesh structure, reducing the weight of the outer ring and enhancing the structural strength. The outer ring is connected to other structures through mounting holes, while the inner ring is fixed to the motor housing. The flow-guiding vanes change the airflow direction.

Benefits of technology

It effectively reduces the overall weight of the fan, enhances structural strength, suppresses deformation, reduces vibration, and ensures a stable connection between the fan and the support components, making it suitable for large-volume, high-power fans.

Abstract

The utility model relates to the technical field of fans, and provides a flow guide structure and a fan. The flow guide structure comprises an inner ring and an outer ring. The inner ring is fixed with a shell of the motor; the outer ring is sleeved on the outer side of the blade and comprises a first flange, a second flange, a connecting bridge and a first reinforcing part, the second flange is sleeved outside the first flange, the first flange is connected with the inner ring through the flow deflector, the second flange is connected with the first flange through the connecting bridge, and the first reinforcing part is connected with the first flange, the second flange and the connecting bridge. In the axial projection of the rotor, the first reinforcing part is in a net shape, and a mounting hole is formed in the center of the first reinforcing part. In this way, the weight of the outer ring can be reduced, the structural strength of the outer ring can be enhanced, the deformation trend can be restrained, the structural strength of the mounting holes can be enhanced through the first reinforcing parts, and operation of a large-size and high-power fan is supported.
