Abstract

An electronic fan assembly with large flow and low noise. The electronic fan assembly is composed of a motor and an impeller driven by the motor. It is characterized in that: the fan blades (2) are eight pieces, two adjacent The fan blades (2) form an included angle a, and there are eight such included angles a; the fan blades (2) take six radial cross-sections along the radial curve bends, and the center of the impeller and the fan blade (2) The midpoint of the root is the reference line, and the angles from the root on the right side of the blade (2) to the top blade (2) are 39°, 25°, 23°, 31°, 41°, and 53°; The midpoint of the root of the fan blade (2) is the reference line, and the angles from the left root of the fan blade (2) to the top fan (2) are 6°, -1°, 1°, 7°, 17°, 41° °, 53°. The present invention reduces the total value of the fan noise and improves the sound quality under the condition of satisfying the flow performance of the fan.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a large-flow and low-noise electronic fan assembly for automobiles. 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 with large flow and low noise. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a large-flow and low-noise electronic fan assembly, the motor controls the rotation, and provides wind power through eight fan blades arranged radially between the hub and the wind protection ring, and satisfies the...
