Embodiment 1
[0014] Embodiment 1: Refer to Figures 1 and 2, an automobile engine cooling fan, including a tray 1, a hub 2 and ribs 3, and blades 4. The impeller is composed of a tray 1, a hub 2, and blades 4, and the blades 4 are airfoil-shaped The cross-section blades, the blade 4 and the hub 2 are integrally formed, the chord length ratio between the inner and outer diameters of each blade 4 is 1:1.1, the angle between the line of gravity center of each section of the blade 4 and the radial straight line is 5°, and each section of the blade 4 The projection distance of the center of gravity line on the rotating shaft is controlled at 2% of the impeller diameter, which is spatially twisted. The connection between the blade 4 and the hub 2 adopts a circular arc transition. shape. The blade 4 is connected with the guide ring 5.
Embodiment 2
[0015] Embodiment 2: Refer to Figures 1 and 2, an automobile engine cooling fan, including a tray 1, a hub 2 and ribs 3, and blades 4. The impeller is composed of a tray 1, a hub 2, and blades 4, and the blades 4 are airfoil-shaped Cross-section blades, blade 4 and hub 2 are integrally formed, the chord length ratio between the inner and outer diameters of each blade 4 is 1:1.5, the angle between the line of gravity center of each section of blade 4 and the radial line is 25°, and the section of blade 4 The projection distance of the center of gravity line on the rotating shaft is controlled at 8% of the diameter of the impeller, which is spatially twisted. The connection between the blade 4 and the hub 2 adopts a circular arc transition. Others are the same as in Example 1.
Embodiment 3
[0016] Embodiment 3: Referring to Figures 1 and 2, an automobile engine cooling fan includes a tray 1, a hub 2 and ribs 3, and blades 4. The impeller is composed of a tray 1, a hub 2, and blades 4, and the blades 4 are airfoil-shaped Cross-section blades, blade 4 and hub 2 are integrally formed, the ratio of chord length between the inner and outer diameters of each blade 4 is 1:1.3, the angle between the line of gravity center of each section of blade 4 and the radial line is 15°, each section of blade 4 The projection distance of the center of gravity line on the rotating shaft is controlled at 5% of the diameter of the impeller, which is spatially twisted. The connection between the blade 4 and the hub 2 adopts a circular arc transition. Others are the same as in Example 1.
