Problems solved by technology

[0005] However, due to the structure of these ribs 103, only a point of cushioning is provided on the top 1021, and the stress will still be locally concentrated on the ribs 103, so the stress that affects or destroys the structural strength of the housing 102 cannot be completely eliminated.

Embodiment Construction

[0033] A fan, a motor and its housing according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be denoted by the same reference numerals.

[0034] Referring to FIG. 2 , a housing 20 according to a preferred embodiment of the present invention includes a top 201 and a wall 202 , wherein the wall 202 is connected to the periphery of the top 201 . The housing 20 of this embodiment can be applied to the base of a motor or the hub of a fan.

[0035] The top 201 is a surface for bearing external force. Here, the top 201 has a plurality of concave-convex structures 203 arranged around the central axis of the top 201 to increase the stress-bearing area of ​​the top 201 . The wall thickness of these concave-convex structures 203 is substantially the same as the wall thickness of the top 201, that is, the wall thickness of these concave-convex structures 203 is approximately the same as the ...

Abstract

The invention is concerned with the shell, includes the top and the wall. It is: the top connects with the edge of the wall; the top is with several concavo convex structures; the concavo convex structure ring set along the central axis of the top in order to increase the stress area of the top. The invention is also concerned with the shell of the motor and fan. The invention not only add fortifier such as rib, but also achieve reinforcement structure by few material, reduce the making cost.

Description

technical field [0001] The invention relates to a fan, a motor and its casing, in particular to a structurally strengthened fan, a motor and its casing. Background technique [0002] With the rapid development of electronic products in the direction of high performance, high frequency, high speed and thinness, the heating temperature of electronic products is getting higher and higher, which is prone to instability and affects product reliability. Therefore, heat dissipation has become an important aspect of current electronic products. one of the important subjects. [0003] Utilizing a fan as a cooling device is a common structural arrangement, please refer to Fig. 1, which shows a kind of existing fan 10, which mainly consists of a plurality of fan blades 101 and a housing 102 to form an impeller, and these fan blades 101 ring The casing 102 is disposed on the periphery of the casing 102, and the casing 102 is used for accommodating a motor (not shown in the figure), and...
