Problems solved by technology

[0002] The electronic fan assembly is widely used as the main heat dissipation device of the engine. The existing electronic fan assembly inevitably has noise during use, and the noise is getting louder with the aging of the electronic fan assembly. Inconvenient, and the setting of the fan blades is not reasonable enough, resulting in insufficient wind power and affecting the use. For this reason, we propose an electronic fan assembly

Abstract

The invention belongs to the technical field of engine cooling equipment and discloses an electronic fan assembly. The electronic fan assembly comprises an electronic fan assembly body. The electronic fan assembly body comprises a fan frame, fan blades, supports and a motor. The supports are arranged along the diagonals of the fan frame in a crossed manner. The supports are fixedly connected with the fan frame through support fixing screws. A rotating bearing is arranged at the crossed position of the supports. A rotating shaft penetrates the rotating bearing. One end of the rotating shaft is connected with the motor, and the other end of the rotating shaft is provided with a fan blade connecting screw head. The motor is arranged on a rear shell. The rear shell is connected with the fan frame through fan frame fixing screws. The fan blade connecting screw head is connected with the fan blades through a connecting piece. According to the electronic fan assembly, renewable polypropylene and polyethylene glycol terephthalate are used as the materials for manufacturing the rotating bearing, the fan frame and the rear shell, and noise generated during work of the electronic fan assembly is lowered.

Description

technical field [0001] The invention relates to engine cooling equipment, in particular to an electronic fan assembly, which belongs to the technical field of engine cooling equipment. Background technique [0002] The electronic fan assembly is widely used as the main heat dissipation device of the engine. The existing electronic fan assembly inevitably has noise during use, and the noise is getting louder with the aging of the electronic fan assembly. Inconvenient, and the setting of the fan blades is not reasonable enough, resulting in insufficient wind power and affecting the use. Therefore, we propose an electronic fan assembly. Contents of the invention [0003] The technical problem to be solved by the present invention overcomes the existing defects, and provides an electronic fan assembly, which uses renewable polypropylene and polyethylene terephthalate as materials for the rotating bearing, fan frame and rear shell , reducing the noise generated by the electron...
