Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Please also see figure 1 with figure 2 , figure 1 is a front perspective view of a fan according to an embodiment of the present invention; figure 2 is a reverse perspective view of a fan according to an embodiment of the present invention.

[0024] Such as figure 1 with figure 2 As shown, the fan of the present invention mainly includes a hub 1 and a plurality of blades 2 arranged at intervals around the hub 1 and extending outward.

[0025] The hub 1 is used to fix and assemble the fan, and the hub 1 further includes a top cover 11 and a tube body 12 . The top cover 11 is circular and located on the top of the hub 1 . If the fixed assembly of the fan is matched by the top cover 11, the center of the top cover 11 can be provided with a circular hole 111 (see figure 2 ), to reinforce the fixed assembly of the fan. The tube body 12 ...

Abstract

The invention discloses a fan. The fan comprises a hub and a plurality of blades arranged around the hub at intervals and extended outwards. Each of the blades comprises a first section provided with a first side and a second side extended outwards from the hub, and a second section provided with a third side and a fourth side extended outwards from the hub, wherein the second side and the third side are jointed together so that the first section and the second section form an included angle on a circumferential cross section. In the way, the wind amount and the wind pressure of the fan are in optimum balance and the comprehensive performances of the fan are improved.

Description

【Technical field】 [0001] The invention relates to a fan, in particular to a fan with segmented blades. 【Background technique】 [0002] With the continuous improvement of material living standards, various electronic products are becoming more and more common, and their functions are becoming more and more powerful. With the increase of integration and the progress of packaging technology, the area of ​​integrated circuits is constantly shrinking, and the accumulation of single area The heat energy will be relatively higher, and the heat dissipation device or heat dissipation system has become one of the indispensable equipment in the current electronic device, because if the heat energy generated by the electronic device is not properly dissipated, the performance of the electronic device will be deteriorated. , it will cause the electronic device to burn out. [0003] Among the existing cooling devices, fans are the most widely used. Generally speaking, fans can be roughl...
