Embodiment Construction
[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0050] It should be noted that when an element or component is considered to be “connected” to another element or component, it may be directly connected to the other element or component or there may be an intervening element or component at the same time. When an element or component is referred to as being "disposed on" another element or component, it can be directly disposed on the other element or component or intervening elements or compone...

A fan comprises a fan frame, a stator and a rotor, wherein the stator and the rotor are arranged in the fan frame. The rotor comprises an impeller, the impeller comprises a body and multiple blades, the blades are annularly arranged on the periphery of the body and extend outwards in a radial shape, the body comprises an annular top and a cylindrical side portion, the cylindrical side portion vertically extends downwards from the periphery of the top, the inner side of the top protrudes and extends to form multiple heat discharge portions, and the multiple heat discharge portions are arranged at intervals to form multiple heat dissipation spaces. According to the fan, heat of the fan, especially heat from a circuit board, is discharged, and therefore the service life of the fan is prolonged, and the reliability of the fan is improved. The invention further provides an electronic device.
Description
technical field [0001] The invention relates to a fan and an electronic device with the fan. Background technique [0002] With the rapid development of electronic technology, the running speed of heating electronic components such as the central processing unit is getting faster and faster, and the heat generated during operation also increases accordingly. In order to dissipate the heat to ensure the normal operation of electronic components, the industry uses fans to Electronic components dissipate heat. A traditional fan generally includes a stator, a rotor and a frame for accommodating the stator and the rotor. However, electronic devices such as central processing units now have higher and higher fan performance, and the size of the fan is required to be more and more miniaturized, so that the circuit board of the fan's own stator also needs to dissipate heat, otherwise the life and reliability of the fan will be reduced. Contents of the invention [0003] In view ...
