Embodiment 1

[0034] see Figure 1 to Figure 5 , The present invention has an outer rotor motor 1, a fixed frame 2 and an impeller 3; the fixed frame 2 has an outer ring body; the outer rotor motor 1 is fixedly connected to the center of the fixed frame 2; the impeller 3 is fixedly connected to the outer rotor motor 1 on the outer rotor; the impeller 3 is rotatably arranged in the outer ring; the impeller 3 includes a coaxially arranged hub 31 and a rotating ring 33; the hub 31 and the rotating ring 33 are distributed along the circumference of the axis of rotation. A blade 32; the hub 31 and the blade root 322 are connected as a whole, and the blade top 323 is connected with the rotating ring 33 as a whole.

[0035] The center of the hub 31 is provided with a through hole for the outer rotor of the outer rotor motor 1 to pass through, and fixing holes are distributed around the circumference of the through hole on the hub 31; the outer rotor of the outer rotor motor 1 is provided with an annul...

Embodiment 2

[0046] The turbulator 321 of the present invention is located at the protrusion of the top 323 of the blade, and it naturally transitions away from the leading edge of the blade 32 and gradually approaches the rotating ring 33, and forms an extension that is integrated with the rotating ring 33 and is higher than other protrusions. 324. Other technical features are the same as the first embodiment.

Abstract

The invention relates to an axial-flow fan. The axial-flow fan comprises an outer rotor motor, a fixing frame and an impeller; the fixing frame comprises an outer ring body; the outer rotor motor is fixedly connected to the center of the fixing frame; the impeller is fixedly connected to an outer rotor of the outer rotor motor; the impeller is rotationally arranged inside the outer ring body and comprises a hub; a plurality of blades are distributed on the hub and along the circumference of the rotating axis; the center of the hub is provided with a through hole for the outer rotor of the outer rotor motor to pass through; the hub is provided with fixing holes which are distributed around the circumference of the through hole; the circumferential surface of the outer rotor of the outer rotor motor is provided with an annular flange connecting plate; and the hub is arranged outside the outer rotor of the outer rotor motor in a sleeving manner and is fixedly connected with the annular flange connecting plate via the fixing holes by virtue of a connecting bolt. According to the axial-flow fan provided by the invention, the overall height is greatly reduced due to a mode that the impeller is connected with the outer rotor motor, so the axial-flow fan is also applicable to some limited installation spaces.

Description

Technical field [0001] The invention relates to an axial flow fan. Background technique [0002] Axial fan is a device that rotates the impeller to flow gas parallel to the fan axis. Axial fans are usually used in occasions with higher flow requirements and lower pressure requirements. Axial fans have a wide range of uses, such as electric fans, air conditioners outside fans, and automotive axial fans. The axial flow fan is mainly composed of an impeller and a casing, with a simple structure but very high index requirements. [0003] When the impeller of the traditional axial flow fan is fixedly connected with the outer rotor motor, the hub of the impeller needs to be sleeved on the outer rotor of the outer rotor motor, and then fixedly connected by bolts. Since the hub of the impeller itself has a certain thickness, after installation, the overall height increases, which is not applicable in some special environments. [0004] At the same time, as the core component of the axial...
