Abstract

The present invention provides a fan assembly. The fan assembly comprises a frame and a fan, the fan is installed in the center of the frame and comprises a plurality of blades, each of the blades is provided with a cutting edge and a back edge, the frame is provided with airflow passages, an airflow outlet of each airflow passage is formed in an inner side wall of the frame facing the fan, and the airflow outlet guides an airflow discharged from the airflow outlet to flow from the back edge of one blade to the cutting edge of the same blade. In addition, a driving device using the above fan assembly is also provided. With adoption of the fan assembly, dust on the fan can be removed without shutting off the fan.

Description

technical field [0001] The invention relates to a fan cleaning technology, in particular to a fan assembly and a driver using the fan assembly. Background technique [0002] Fans such as heat dissipation fans need to be in operation for a long time. After long-term operation, a lot of dust and fibers will accumulate on the blades of the fan, which will affect the heat dissipation efficiency of the fan, and even cause the fan to be stuck in extreme cases. For example, for the fan on the drive used in the factory environment, the drive cannot usually be shut down (that is, the fan cannot be shut down) due to economic considerations, because the stop of the drive means that the production equipment will also be shut down, causing economic loss. In this case, if the fan is stuck, it will cause the drive to fail prematurely. [0003] However, under current conditions, the process of cleaning and maintaining the fan generally requires the driver to be shut down, wait for the rad...
