Embodiment Construction

[0027] In order to solve the technical problem of excessive fan noise in the prior art, an embodiment of the present invention provides a fan, which includes: a base; a stator fixedly arranged on the surface of the base; an impeller rotatably arranged on the On the periphery of the stator, the impeller includes fan blades of at least two structures. Since the impeller includes two fans with different structures, the frequency spectrum of the sound wave of the fan noise is shifted, thereby reducing the peak value of the sound wave under a single frequency spectrum, thereby having Technical effect of reducing fan noise.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a ...

Abstract

The invention discloses a fan and electronic equipment. The technical problem that the noise of a fan in the prior art is too large is solved. The fan comprises a base, a stator and an impeller. The stator is fixedly arranged on the surface of the base. The impeller is rotatably arranged on the periphery of the stator and comprises at least two fan blades including a first fan blade and a second fan blade, and the first fan blade and the second fan blade are different in structure. Due to the fact that the impeller comprises the two fan blades different in structure, the frequency spectrum of sound waves of the noise of the fan is partially offset and is distributed within the wider range, the peak value of the sound waves under the single frequency spectrum is lowered, and then the technical effect of lowering the fan noise is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a fan and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic technology has also been developed rapidly, and more and more electronic devices have been produced, such as tablet computers, notebook computers, all-in-one computers and so on. With the gradual increase of the processing capacity of these electronic equipment, its energy consumption is also gradually increased, so the heat generated by it also increases. In order to prevent the loss of electronic equipment due to temperature rise, many electronic equipment have cooling devices. , such as: cooling fans, heat sinks, etc., through these heat dissipation devices, the heat of electronic equipment can be quickly transferred to the environment, and then play a role in heat dissipation. [0003] Please refer to figure 1 , which is a structural diagra...
