Problems solved by technology

[0004] In order to increase the number of fan blades more, the thickness of the fan blades needs to be reduced, but this will reduce the strength of the fan blades, making them unable to meet the needs of use
So there is currently no good way to make fans with thinner blades

Abstract

The invention discloses a fan blade structure and a device, and provides a fan blade structure with ultra-thin fan blades. The fan blade structure comprises a hub and the blades, wherein the hub comprises a center part and an edgefold surrounding the center part; the edgefold has a gap; and the fan blades pass through the gap to be fixed on the edgefold.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a fan blade structure and equipment. Background technique [0002] In order to enhance the heat dissipation effect of current computer equipment, fans are generally used. Various fans may be set in computer equipment, such as central processing unit (Central Processing Unit, CPU) fan, graphics card fan, power supply fan, chassis rear fan, chassis front fan, and top fan, etc., these fans are all for strengthening heat radiation. [0003] The air volume and wind power of the fan are mainly related to the fan motor and fan blades. Generally speaking, the more blades the fan has, the better the air supply effect will be. Moreover, the more fan blades, the "wind" can be cut into smaller pieces, so that the blown wind is softer and the mute effect is better. [0004] In order to increase the number of fan blades more, it is necessary to reduce the thickness of the fan blades, b...
