Abstract
The utility model provides a novel axial fan for an air conditioner outer machine, which comprises a hub and two vanes, wherein the upper end surface of the hub is round, the lower end surfaces are two arc-shaped twisted, staggered and abutted structures, the ratio of the maximum outer diameter of the lower end surface of the hub to the outer diameter of the upper end surface is 1.7-2.0, the hub ratio (the upper end surface) is 0.21-0.27, and the hub structure is mainly used for increasing the area of an air inlet and improving the connecting strength with the vanes. The outer margin of each vane is provided with a fluttering structure, the radial cross section of a turned-over edge is arc-shaped, and the height of the turned-over edge is 1/16-1/14 of the maximum outer diameter of the vane. The fan has simple structure, light weight, good radiating effect and excellent overall performance.
Description
Technical field
The utility model relates to the novel axial fan of a kind of air-conditioning outer machine.
Background technique
Fan hub in the existing air conditioner is than between 0.27-0.37, and therefore to expend raw material more for a plurality of blades, and efficient is low, and the noise height is unfavorable for producing.
The model utility content
The purpose of this utility model provides a kind of efficient height, and noise is low, the novel axial fan of the air-conditioning outer machine that can save material.
The technical solution of the utility model is:
Air-conditioning outer machine of the present utility model comprises wheel hub and two blades with novel axial fan, axis hole is arranged in the middle of the wheel hub, the wheel hub upper-end surface is circular, the lower end surface is that two circular arcs are twisted the docking structure that staggers, wheel hub lower end surface maximum outside diameter is 1.7-2.0 with upper-end surface external diameter ratio, and hub ratio (upper-end surface) is 0.21-0.27, and two blades have turnup structure on the wheel hub, the flange radial cross section is circular arc, and the flange height is the 1/16-1/14 of blade maximum outside diameter.
Any point is along symmetry on the diametric(al) on two blades that distribute on the described wheel hub.
Because the wheel hub upper-end surface is circular, has increased the suction port area; The lower end surface is that two circular arcs are twisted the docking structure that staggers, strengthen join strength with blade, the hub ratio ratio of impeller outer diameter (diameter of wheel hub upper-end surface with) is 0.21-0.27, keeping under the required flow rate condition, adopt than small hub ratio as far as possible, to reduce impeller diameter, thereby reduce the radial dimension and the noise of machine, because of considering the restriction of root of blade load, lower end surface and blade to wheel hub improve as follows: the lower end surface is that two circular arcs are twisted the docking structure that staggers, the join strength of increasing and blade, and two blades have turnup structure on the wheel hub, the flange radial cross section is circular arc, and the flange height is the 1/16-1/14 of blade maximum outside diameter.Any point on two blades that distribute on the described wheel hub along symmetry on the diametric(al), is made symmetrical configuration, process more convenient.
This air-conditioning outer machine is with novel axial fan efficient height, and noise is low, and can save material, and reduces cost.

Fig. 2 is the worm's eye view of the utility model axial fan wheel hub.
Fig. 3 is the sectional view of the utility model blade.
Fig. 4 is the left view of the utility model axial fan wheel hub.
Embodiment
With reference to accompanying drawing.Air-conditioning outer machine of the present utility model comprises wheel hub 2 and two blades 1 with novel axial fan, and it is circular that axis hole 3, these wheel hub 2 upper-end surfaces are arranged in the middle of the wheel hub 2, has increased the suction port area; The lower end surface is that two circular arcs are twisted the docking structure that staggers, lower end surface outside diameter d 2 is 1.7-2.0 with upper-end surface outside diameter d 1 ratio, strengthen join strength with blade, hub ratio (the hub diameter d1 of upper-end surface and the ratio of impeller outer diameter D) is 0.21-0.27, keeping under the required flow rate condition, adopt than small hub ratio as far as possible, reducing impeller diameter, thereby reduce the radial dimension and the noise of machine.Consider the restriction of root of blade load, the lower end surface is the two circular arcs distortion docking structure that staggers, and makes that two blades have turnup structure 4 on the wheel hub 2, and flange 4 radial cross sections are circular arc, and flange 4 height H are the 1/16-1/14 of blade maximum outside diameter D.
Claims (2)
1. novel axial fan of air-conditioning outer machine, comprise wheel hub and two blades, axis hole is arranged in the middle of the wheel hub, it is characterized in that: the wheel hub upper-end surface is for circular, and the lower end surface is that two circular arcs are twisted the docking structure that staggers, and wheel hub lower end surface maximum outside diameter is 1.7-2.0 with upper-end surface external diameter ratio, hub ratio (upper-end surface) is 0.21-0.27, two blades have turnup structure on the wheel hub, and the flange radial cross section is circular arc, and the flange height is the 1/16-1/14 of blade maximum outside diameter.
2. the novel axial fan of air-conditioning outer machine according to claim 1 is characterized in that: any point is along symmetry on the diametric(al) on two blades that distribute on the described wheel hub.
