Embodiment Construction

[0027] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only referring to the directions of the drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention. Moreover, the same reference numerals represent the same elements throughout the embodiments.

[0028] The main inventive idea of ​​the present invention is that, as mentioned above, the spacing between the blade traces at the outer diameter and inner diameter of the fan blade in the prior art and the inner surface trace of the casing along the The direction of the rotation axis is exactly the same. The improvement is that the distance between the blade trace at the outer diameter, or i...

Abstract

The invention provides a fan and an electronic product with the same. The fan comprises a rotation shaft including a rotation axis, a plurality of fan blades arranged on the rotation shaft to rotate through the rotation shaft and a casing for accommodating the plurality of the fan blades. The plurality of the fan blades comprise a first fan blade, and the distance between the blade trace at the position of the outer diameter and / or the inner diameter of the first fan blade and the inner surface trace of the casing is not completely consistent along the rotation shaft axis direction.

Description

technical field [0001] The invention relates to a fan and an electronic product with the fan. Background technique [0002] Most electronic products have a fan, such as a heat dissipation fan, for cooling the electronic product so that the electronic product can work under a suitable temperature condition. As the performance of electronic products is getting higher and higher, the heat generated per unit time is also increasing, so the heat dissipation performance of fans is required to be higher and higher. On the other hand, the improvement of fan cooling performance means that the air volume or wind speed generated per unit time is getting higher and higher, which will directly lead to increased noise. However, users have higher and higher noise requirements for electronic products, which requires optimizing the structure of the fan as much as possible to reduce noise under the premise of satisfying the heat dissipation performance of the fan. [0003] The structure of ...
