Abstract
The utility model discloses a motor fan which comprises blades, wherein the blades are fixed on a fan shaft sleeve. The utility model is characterized in that an included angle of 60 degrees is formed between the upper side of the front end of the blade, and the perpendicular line of the shaft line of a motor; an included angle of 35 degrees is formed between the lower side of the back end of the blade, and the perpendicular line of the shaft line of the motor; and an included angle of 45 degrees is formed between the upper side of the back end of the blade, and the perpendicular line of the shaft line of the motor. The utility model has the embodiment that seven blades are uniformly distributed. Through changing the inlet and outlet inclination angle, and the dimension shape of the outer diameter and the width of the fan blades, the noise and the vibration of the motor are obviously reduced, the air friction is reduced, and the motor efficiency is improved.
Description
Technical field:
The utility model relates to a kind of electrical motor fan.
Background technique:
Electrical motor fan of the prior art adopts two-way centrifugal benzvalene form fan structure usually, and fan fan blade and air friction loss ratio are bigger, have reduced fan work efficient.In addition, fan material adopts usually and strengthens the poly-third ethene material, has also had influence on the intensity of fan.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and it is smaller to provide a kind of wind to rub, the electrical motor fan that the big efficient of intensity is high.
The technical scheme in the invention for solving the above technical problem is: this electrical motor fan, comprise blade, vanes fixed puts at fan shaft, it is characterized in that blade front end top and electrical axis vertical line angle are 60 ° of angles, blade rear end bottom is 35 ° of angles with electrical axis vertical line angle, top, blade rear end and electrical axis vertical line angle angle at 45.
The present embodiment blade is equally distributed 7.
The utility model makes the friction of electrical motor fan and air reduce by changing inclination angle, gateway and the external diameter and the width dimensions shape of fan blade, has improved the efficient of motor.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the structural representation of the utility model embodiment blade.
Fig. 3 is that the K of Fig. 2 is to view.
Embodiment:
Referring to Fig. 1～Fig. 3, the utility model embodiment comprises blade 1, blade 1 is by being bolted on the fan axle sleeve 2, blade 1 front end top and electrical axis vertical line included angle A are 60 ° of angles, blade 1 rear end is following to become 35 ° of angles with electrical axis vertical line included angle B, blade top, 1 rear end and electrical axis vertical line angle C angle at 45.
Present embodiment blade 1 is equally distributed 7.
The utility model makes the friction of electrical motor fan and air reduce by changing inclination angle, gateway and the external diameter and the width dimensions shape of fan blade 1, has improved the efficient of motor.
