A fan corrugated bracket

Abstract

The invention discloses a corrugated bracket of a fan. The corrugated bracket of the fan comprises an air guide ring, a plurality of flow guide blades and a bracket hub, wherein a motor is mounted atone side of the bracket hub; fan blades are connected to the motor through a rotating shaft and are mounted at the other side of the bracket hub. The corrugated bracket of the fan further comprises anopening expansion structure which is arranged at the end part of the air guide ring; the flow guide blades are arranged between the opening expansion structure and the bracket hub; the line of the inner wall of the opening expansion structure is inclined; corrugated noise reducing structures, comprising at least one group of wave crests and wave troughs, are arranged at the rear edges of the flowguide blades; each group of wave crests and wave troughs is arranged in the direction from the rear edges of the flow guide blades to the front edges of the flow guide blades. With the adoption of the corrugated bracket of the fan, the motor can be supported during being mounted, and moreover, the flow guide blades are corrugated, so that air output by the fan can be rectified, and as a result, the fan eddy loss is decreased, the fan efficiency is improved, and the broadband eddy noise is reduced.

Description

technical field [0001] The invention relates to the field of fan equipment, in particular to a fan corrugated bracket. Background technique [0002] In the existing industries such as buses, automobiles and electrical appliances, in order to avoid abnormal operation of electronic equipment caused by excessive temperature of electronic components, it is necessary to dissipate heat from electronic equipment. The usual cooling equipment is a fan device. In the fan device, the fan bracket mainly plays the role of supporting the installation of the fan motor and connecting the fan. The structure of the guide vanes on the fan bracket is simple, and most of them are flat brackets extending in the radial direction. During the rotation of the fan, the airflow generated passes through the guide vanes, and the airflow will flow out along the trailing edge of the guide vanes, resulting in air separation. , did not play the role of diversion, increasing the broadband eddy current noise ...
