Embodiment 1

[0054] figure 1 and figure 2 A preferred assembly structure of the axial flow cooling fan of the present invention is shown, which includes an impeller 1 , a windshield connection mechanism 2 and a motor 3 , and the impeller 1 is assembled in the windshield connection mechanism 2 through the motor 3 .

[0055] like image 3 As shown, the impeller 1 includes a hub 11 , blades 12 and a windshield 13 , the root of the blade 11 is connected to the hub 12 and extends radially outward around the hub, and the top of the blade 12 is connected to the windshield 13 .

[0056] like Figure 4 As shown, the hub 11 is provided with a number of flat slots 111, and the flat slots 111 are unevenly distributed in the circumferential direction; the size and number of the flat slots 111 can also be adjusted to ensure the air volume, and at the same time, the relatively large heat generated by the motor can be partially Dissipation through flat slots. The surface circumference of hub 11 is pr...

Abstract

The invention discloses an axial-flow cooling fan assembly structure. The axial-flow cooling fan assembly structure comprises an impeller, a wind cover connecting mechanism and a motor; the impeller is assembled in the wind cover connecting mechanism through the motor and comprises a hub, blades and a wind protection ring; the roots of the blades are connected to the hub; the tops of the blades are connected to the wind protection ring; the wind cover connecting mechanism comprises a wind cover, ribs and a motor connecting cover; the roots of the ribs are connected to the motor connecting cover; the tops of the ribs are connected to the wind cover; the ribs comprise a plurality of airflow guide ribs; the cross section of each airflow guide rib is of a wing shape; each airflow guide rib isprovided with a twisting structure arranged relative to the radial direction; the rear end of the motor is arranged in the motor connecting cover; and the front end of a rotating shaft of the motor iscoaxially connected to the hub. The axial-flow cooling fan assembly structure has the advantages of being large in flow, good in cooling effect, good in sound quality and the like.

Description

technical field [0001] The invention belongs to the technical field of engine cooling fans, and in particular relates to an assembly structure of an axial flow cooling fan. Background technique [0002] Current conventional engine cooling fans have the following disadvantages: [0003] 1. The airfoil surface of the conventional blade is smooth, which can meet the flow and noise requirements. However, the order noise value of this structure is relatively large, the total sound pressure level is relatively high, and the sound quality is not ideal. [0004] 2. Conventional windshield ribs are arranged at the air outlet of the blades to support the motor and strengthen the structural strength, but the unsuitable arrangement and rib structure have a certain negative impact on the air outlet flow, making the overall efficiency of the fan biased. Low, the sound quality deteriorates. [0005] 3. The motor of the conventional fan is assembled with the windshield through the motor ...
