Problems solved by technology

There is no structural support for the torsion angle of the blades relative to the change of the plastic ring, which causes the blade torsion angle to be unstable when the fan rotates, the air in the center part disperses the wind pressure unevenly, and the beating of the fan end surface affects the dynamic balance of the fan

Abstract

The invention discloses an aileron type engine fan and belongs to the technical field of engine fans. The aileron type engine fan comprises a metal disc, a plastic ring and a plurality of fan blade parts. The plastic ring is tightly wrapped to the edge of the outer circumferential wall of the metal disc, the fan blade parts and the plastic ring are formed integrally and are uniformly distributed around the axis of the plastic ring, each fan blade part is obliquely arranged on the outer side wall of the plastic ring, and the inclination directions of all the fan blade parts are same. As roots of the fan blade bodies are embedded into the plastic ring formed by injection molding and wrapping, an aileron type structure is distributed in a position, close to the plastic ring, of each fan bladebody to support and fix a torsional angle changing, relative to the plastic ring, of each blade and is sequentially and circularly connected to the root of previous fan blade body embedded into the plastic ring, the strength of the fan bade body is improved. A heat-dissipating air inlet runner is formed in the center part. The stability of the torsional angle of the fan blade body is enhanced bythe structure, so that a jerk value on the end surface of the fan is avoided, and the air pressure of the air inlet runner is enhanced.

Description

technical field [0001] The invention relates to the technical field of engine fans, in particular to an aileron type engine fan. Background technique [0002] The engine needs to add anti-freezing fluid to circulate through the engine and the water tank. A fan is installed at the rear end of the engine water tank to cool the water tank through suction or exhaust to achieve the purpose of cooling the engine. [0003] In the prior art, the fan has a ring-shaped hub at its center to connect and support the root of the blade and is connected to the transmission system. Since the fan blade usually twists with the center line to form a torsion angle, the hub has a certain width to hinder the central air intake and heat dissipation of the fan when it rotates. . [0004] Also there is no hub to connect the blades, and the metal disc is wrapped by injection molding to form a plastic ring, and the circumference of the plastic ring is unevenly distributed with 7-10 blades. There is n...
