a fan impeller

Abstract

The invention discloses a fan impeller, which comprises a hub which can be mated with a motor, an outer ring, and main blades installed between the hub and the outer ring, and a plurality of auxiliary fan blades are installed on the circumferential edge of the hub , the auxiliary fan blades extend along the axial direction of the hub, and a number of ventilation openings are opened on the hub, and the air supply flows from the ventilation openings to the auxiliary fan blades, so that the auxiliary fan blades When rotating, an air volume flowing along the radial direction of the hub can be formed. In the fan impeller provided by the present invention, through the setting of the auxiliary fan blades and the ventilation opening, the air flow enters from the ventilation opening of the hub and exits from the radial direction of the wind wheel under the rotation of the motor. Wind can greatly increase the heat dissipation rate of the motor casing, thereby improving the temperature rise inside the motor, prolonging the service life of the motor, and ensuring the working stability of the fan impeller.

Description

technical field [0001] The invention relates to the field of fan equipment, in particular to a fan impeller. Background technique [0002] During the working process of the automobile engine, or in the boiler room, it is generally necessary to use a fan to cool down. The motor drives the fan to rotate, and the blades of the fan form an air volume to achieve the purpose of cooling. [0003] In the prior art, fan impellers only have main blades, which only rely on the main blades to generate a certain amount of air volume to reduce high-temperature environments such as engines or boiler rooms. However, the motor used to drive the fan impeller rotates due to long-term high temperature Running, the aging of the motor is accelerated, and the overall service life is reduced, which in turn affects the cooling effect of the fan impeller. [0004] Therefore, how to improve the cooling effect of the fan impeller is a technical problem to be solved by those skilled in the art. Conte...
