Abstract
The utility model relates to a high-wind-quantity low noise fan and belongs to the technical field of automotive air conditioning. The high-wind-quantity low noise fan comprises a fan frame (1), a wind wheel (2) and a motor (3), the wind wheel (2) comprises axial wind shield rings (2b) and radial wind shield rings (2c). The high-wind-quantity low noise fan is high in pressure wind effect since loss of wind quantity can be reduced when wind blades rotate at high speed, wind quantity can be increased as compared with other similar products under same conditions. In addition, reinforcing ribs (1a) similarly shaped in bent operating cranks are arranged on the fan frame (1), noise can be effectively lowered when air flows through the fan frame (1) during working of the fan.
