| description | The utility model relates to an ultra-thin automobile cooling fan with ribs. The ultra-thin automobile cooling fan comprises blades, a tray and a hub. The annular protruding wavy reinforcing rib is arranged along the edge of the upper end face of the hub and formed by alternately connecting peak portions with valley portions. Each peak portion corresponds to one blade. The two reinforcing ribs are arranged between the root on one side face of each blade and the hub. One end of the reinforcing rib I is connected with the adjacent valley portions on the wavy reinforcing rib. The other end of the reinforcing rib I extends along the root of the outer edge of an inward-concave arc line of the blades. The reinforcing rib II is in an arc shape. One end of the reinforcing rib II is connected with the corresponding peak portion on the wavy reinforcing rib, and the other end of the reinforcing rib II extends towards the root of the outer edge of the outward-convex arc line of the blades. Protruding embedded columns are arranged at the positions, corresponding to the blades, of the lower end face of the hub in the circumferential direction. According to the ultra-thin automobile cooling fan with the ribs, the structure is simple, the fan strength is increased due to the arrangement of the reinforcing ribs, the rotation resistance is reduced due to the fact that the thickness of the blades is small, and therefore the blast capacity of the fan is greatly increased. |
