The invention provides a cooling fan for suppressing noise. The cooling fan comprises a shell. A stator is fixed into the shell. A bearing fixing ring is mounted in a central hole of the shell and a central hole of the stator. A rotating shaft is fixedly mounted on the bearing fixing ring though multiple bearings. A rotor is fixed to one end of the rotating shaft and fixedly provided with a fan blade. The fan blade rotates along with the rotor and outputs wind. In addition, the cooling fan further comprises bearing vibration reduction parts or a fixing ring flexible sleeve, wherein the bearingvibration reduction parts are arranged on the bearings, and the fixing ring flexible sleeve is arranged on the bearing fixing ring and used for alleviating vibration transmission. A blade body of thefan blade is provided with flow guiding reinforcing ribs, and the flow guiding reinforcing ribs are used for reinforcing the strength of the blade body and sorting and pressurizing air flow. According to the cooling fan, by means of flexible parts, the vibration transmission efficiency is lowered, rotation stability is improved, and noise is greatly reduced. In addition, by means of the flow guiding design of the surface of the fan blade, the air flow on the surface can be sorted while the structural strength of the blade surface is improved; and air noise is further reduced.
Description
technical field [0001] The invention relates to the technical field of noise reduction, in particular to the noise reduction of fans, in particular to a cooling fan for suppressing noise. Background technique [0002] Cooling fans are widely used in modern society. Whether it is large machinery or computers, cooling fans can be seen. Cooling fans are very important to the operation of equipment. The heat dissipation performance of cooling fans is also a very important factor for equipment. important indicators. Especially for micro electrical appliances, a good heat dissipation environment is the basis for equipment operation. However, the heat dissipation performance of most miniature heat dissipation fans on the market is very general, and the heat dissipation fans are noisy and vibrate strongly when they work. This is detrimental to electronic equipment. However, high-speed, low-vibration cooling fans are often achieved by improving the precision of equipment processin...
