Creative Instructions (1) [Technical Field] It is 浐 2Ϊguan—a kind of DC cooling fan blade damping place with hibiscus ribs; the fan blade end edge damping knot of the fan blade wheel is especially equipped with% ribs—the body is set at each Fan blade outwards] It is mainly used to align the upper corners of the end edges of each fan blade with each other, so that the outer edges of the ring plates connected between the segments are misaligned. Those who use resonance noise and [prior art]. Inside the traditional cooling fan is a clock with a predetermined number of fans extending outwardly from the periphery of the bell seat .: It is unavoidable that the radial flow field from the central air to the radial flow field is unavoidable in conjunction with J. Forming% ^ 出 # This axial flow field turns into, and with the increasing function of 越: strong, two = ^^ + two degrees more and more, the cooling fan needs to become larger, and the wind m is also getting more and more It is relatively high, which makes the blade ^ more and more strict ^, the edge of the blade's edge will generally reduce its rigidity with the size ~; ^ It is difficult to resist the full flow, the disturbance, and the resonance noise caused by it is getting higher and higher. Leading to the breakage and damage of the fan blade ... and so on. Therefore, how to develop a fan structure different from the traditional cooling fan to 'enhance the strength of the blade'? The chatter and resonance noise of fate are really new products designed by consumers, and they are the goals that the related industries need to work hard to develop. " < 【Content】 τ

Technical problem to be solved = It is for the cooling fan fan to strengthen the film to suppress the eddy current phenomenon, and research and design. b. Technical means to solve the problem The main purpose of this creation is to suppress the vibration structure. It mainly uses the upper corner pair of the edge of the ring rib extension to make each blade match the ring rib and the middle section of each blade. Special 1 1 Practical function of suppressing and preventing fan resonance noise. The other main purpose of a book, the damping structure of the fan blades, is mainly used to displace the ring ribs that are not placed at the ends of the fan blades extending outward, so that the corner couplers are connected and fixed to each other to enhance the effect. . The fan blade damping structure of the fan blade completed according to the above purpose has a cooling fan wheel. The fan blade wheel is surrounded by the central shaft seat and regardless of the middle section of each fan blade extending outward, and is mainly formed by one or one fan blade extending outward. The above ring ribs, in which the ring position is arranged, or the damping structure of the pair of upper and lower ring leaf end edges, with strong anti-tremor and resonance noise are provided. A DC cooling fan blade is provided integrally on each The upper corner couple of the fan blade's outward end edge is connected and fixed to each other. The outer edge of the knot ring plate is dislocated. The vibration of the extended edge edge when the leaf rotates is to provide a direct-flow cooling wind that belongs to the upper and lower corresponding ring ribs. At the upper and lower corners of the body, the strength of the blades of each pair of f blades, or the edges of the multiple blades, and the work of suppressing the eddy current are created. A rotating fan-shaped blade is provided to extend outward. Is there a predetermined number of fan blades, and whether the bottom edge of the ring plate has an edge pair of connected ring plates, a rib is integrally provided with the inner and outer edges of the ring plate, and the ribs need to be misaligned, so that each
