Micro-thin efficient centrifugal fan

Abstract

The utility model provides a micro-thin type efficient centrifugal fan. The micro-thin type efficient centrifugal fan comprises an impeller; the driving assembly is connected with the impeller and used for driving the impeller to rotate; the control assembly is connected with the driving assembly and used for controlling the driving assembly to drive the impeller to rotate; and the volute and volute cover assembly is used for accommodating the impeller, the driving assembly and the control assembly. According to the micro-thin efficient centrifugal fan and the manufacturing method thereof, on the premise that the requirement for the size of the centrifugal fan in the aerospace field is met, the connecting strength of the volute, the volute cover, the magnet yoke and the fan blades is high, the structural stability is good, high-efficiency operation of the centrifugal fan can be achieved under the same size, and the service life of the centrifugal fan is prolonged. And compared with a fan with the same size, higher air volume and air pressure can be provided.
