AI Technical Summary

Problems solved by technology

However, when the fan is running, due to the uneven distribution of the mass of the rotor and the torque transformation caused by the commutation of the motor, the fan will vibrate, make noise, etc.
The vibration of the fan is likely to cause the installation of the fan to loosen, which in turn affects the structural stability of the entire cooling device.

Abstract

The invention relates to a fan frame, which includes a frame and a base surrounded by the frame. The base is connected to a center column to be rotationally connected with an impeller of a cooling fan. The base includes a disc and a base extending outward from the periphery of the disc. Ribs connect the disc and the frame. The frame is also provided with a buffer element. The buffer element includes a first buffer element, and the first buffer element is formed on the disc. The invention also relates to a cooling fan using the fan frame.

Description

technical field [0001] The invention relates to a cooling fan, in particular to a fan frame and a cooling fan with the fan frame. Background technique [0002] With the rapid development of electronic technology, the running speed of heating electronic components such as the central processing unit is getting faster and faster, and the heat generated during operation also increases accordingly. In order to dissipate the heat to ensure the normal operation of electronic components, the industry uses fans to Electronic components dissipate heat. A traditional fan generally includes a stator, a rotor and a frame for accommodating the stator and the rotor. The stator includes a stator core and coils wound on the stator core. The rotor ring is arranged on the periphery of the stator and includes magnets opposite to the coils. When working, the coil is energized so that the magnetic field generated by the stator interacts with the magnet of the rotor, and the rotor is driven to...
