Problems solved by technology

However, the fan blade of this structure has a very obvious disadvantage, that is, after the fan blade is installed on the drive motor, it is easy to generate resonance and noise during operation, and the work efficiency is low, and the energy consumption is significantly increased.
Especially on the engine used in the car, the loud noise will obviously reduce the comfort of the car, and the low efficiency and high energy consumption will obviously increase the running cost of the car

Embodiment Construction

[0011] Such as figure 1 Shown is a fan blade structure for an automobile engine that can significantly improve efficiency and significantly reduce noise provided by the present invention. The fan blade structure includes a blade 1 and a mounting frame 2, each of the fan blade structures includes at least six pieces of the blades 1, and the blades 1 are divided into at least three groups of blade groups 3 on average, and each group The blade groups 3 are uniformly distributed on the mounting frame 2 in units of groups along the circumference of the mounting frame 2, and the installation distance between adjacent two blades 1 in each group of blade groups 3 is smaller than that of the group. The installation spacing between two adjacent sets of blades 3 of the unit. Since the existing blades 1 that are evenly distributed in the circumferential direction of the mounting frame 2 are grouped, and then the groups of blade groups 3 are arranged in the circumferential direction of th...

Abstract

The invention discloses fan blade structures, particularly discloses a fan blade structure for an automobile engine and belongs to the technical field of the design and manufacture of automobile engine accessories. The fan blade structure for the automobile engine, disclosed by the invention, has the advantages that the efficiency can be increased obviously and the noise can be lowered remarkably. The fan blade structure comprises blades and a mounting frame, wherein each fan blade structure comprises at least six blades, all the blades are evenly divided into at least three blade groups, all the blade groups are uniformly distributed on the mounting frame along the circumferential direction of the mounting frame in a manner of taking each group as a unit, and the mounting spacing between the corresponding adjacent two blades in each blade group is smaller than the mounting spacing between every two adjacent blade groups which take groups as units.

Description

technical field [0001] The invention relates to a fan blade structure, in particular to a fan blade structure for an automobile engine, and belongs to the technical field of design and manufacture of automobile engine accessories. Background technique [0002] At present, whether it is an electric fan used in daily life, an exhaust fan used in industrial production, or a cooling fan used in the engine industry, its blades are evenly arranged along the circumference on the mounting frame, that is, adjacent blades The mounting spacing between them is approximately equal. The advantage of the fan blade with this structure is that the structure design of the injection mold is simple, and the production cost of the mold is relatively low. However, the fan blade with this structure has a very obvious disadvantage, that is, after the fan blade is installed on the drive motor, it is easy to generate resonance and noise during operation, and the work efficiency is low, and the energ...
