The technical scheme of the utility model is as follows: a radiator fan comprises a fan guard, left side blades, a left side direct current brush motor, right side blades and a right side direct current brush motor; the number of the wind-protecting ring reinforcing ribs on the left side of the wind-protecting cover is 8; and three guide plates are added on the left side of the wind shield and the wind shield ring: the first guide plate is positioned at the left upper position of the wind guard ring, the second guide plate is positioned at the right upper position of the wind guard ring, and the third guide plate is positioned at the right lower position of the wind guard ring.
Further, the first guide plates transversely span the reinforcing ribs at two sides, and are inclined inwards by 25.6 degrees in the axial direction to extend to the height of the reinforcing ribs.
Further, the second guide plates span the reinforcing ribs at two sides and extend to the height of the reinforcing ribs along the axial direction.
Further, only one side of the third guide plate is connected with the reinforcing rib, and the third guide plate axially extends to the height of the reinforcing rib.
Further, the number of the left-side wind blades is 7, and the number of the right-side wind blades is 9.
Further, the number of the wind-protecting ring reinforcing ribs on the right side of the wind-protecting cover is 7.
The beneficial effects of the utility model are as follows: the wind shield is characterized in that three guide plate structure designs are added to the wind shield left side wind shield ring, wherein the first guide plate structure is positioned at the left upper position of the wind shield ring, the guide plates span the reinforcing ribs at two sides, and the guide plates are inclined inwards by 25.6 degrees in the axial direction and extend to the height of the reinforcing ribs. The second guide plate structure is positioned at the right upper position of the wind protection ring, and the guide plate stretches across the reinforcing ribs at two sides and axially extends to the height of the reinforcing ribs. The third guide plate structure is positioned at the right lower position of the wind protection ring, and only one side of the guide plate is connected with the reinforcing rib and extends to the height of the reinforcing rib along the axial direction. The design can effectively reduce 7-order noise of the fan on the premise of not influencing the air quantity through verification.
