New description: [New technical field] A centrifugal fan blade structure, especially a centrifugal fan blade structure that uses a double-layer fan blade to enhance the superconducting effect of the fan and reduce noise. [Prior Art] The current electronic «prompt development, the performance of electronic components is slightly improved. As the speed of operation f is faster, the heat generated by it will generate a larger amount of heat. If the heat cannot be instantly dissipated, the electronic component operation The efficiency will be reduced, and in severe cases, the burn will be caused. Therefore, the limited (four) system is used for the antipyretic through a small centrifugal fan, which mainly includes a frame, a fan wheel, and a ring, and the fan. The outer plurality of light bodies, the frame has an air inlet at each of the upper and lower sides, and the side has an air outlet σ, and when operating, the fan blade rotating belt _ air flows from the air inlet The shaft fan wheel of the incoming person is smaller than the wind tunnel (4). Turning to this, see PU and α Hai projecters mainly by changing the shape of the blade body, in order to achieve the wind pressure and air volume of the production of 2, but the effect of changing the shape of the blade body is limited. The material, and the fan blade structure, her material is relatively limited; therefore, the prior art has the following disadvantages: 1. The structural design is limited; 2. The supercharging effect is limited; 3. The diversion efficiency is poor. [New content] 1002,19477 1013Ό645.Ζ7-0 M429908
