Abstract

The invention discloses an air guide device for an axial fan. The air guide device for the axial fan comprises a protecting shell, and the protecting shell is internally provided with a cavity. A guide pipe is arranged at the axial center position of the protecting shell, the guide pipe is parallel to the axial position of the protecting shell, and a plurality of connection strips are arranged between the outer circumferential face of the guide pipe and the inner circumferential face of the protecting shell. The guide pipe is internally provided with a rotating shaft in a sleeving manner, theouter circumferential face of the rotating shaft is sleeved with a casing pipe, the casing pipe is installed on the end portion of the guide pipe, and the outer circumferential face of the casing pipeis sleeved with an air guide base. A sleeving groove is formed in the axial center position of the air guide base, and the air guide base is arranged on the outer circumferential face of the casing pipe in a sleeving manner through the sleeving groove. The outer circumferential face of the air guide base is provided with a plurality of lugs. The outer end of each lug is provided with a protrudingpart, an air guide groove is formed between every two adjacent lugs, and an opening is formed between every two adjacent protruding parts. According to the air guide device for the axial fan, by means of rotation of the rotating shaft, blades can be controlled to achieve rotation, wind energy generated by the blades is guided and conveyed through the air guide grooves, and therefore guiding and conveying control over the wind energy can be conveniently carried out.

Description

technical field [0001] The invention relates to an air guiding device, in particular to an air guiding device for an axial flow fan. Background technique [0002] There are two types of fans, axial flow and radial flow, which are divided according to the flow direction of the air when the fan is working. When an axial fan works, the blades push the air to flow in the same direction as the shaft, so it is called an axial fan; while a radial fan works, the blades push the air to flow in a direction perpendicular to the shaft, so it is called a radial fan. The wind energy generated by the blades of the existing axial fan is inconvenient to guide and control, and the guide control efficiency is low. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a rotation shaft that can control the rotation of the blades, and the wind energy generated by the blades is guided and conveyed through the a...
