Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chassis accessories, in particular to a micro inner rotor turbo fan. Background Art
[0002] Turbofan, also known as centrifugal fan, is commonly used in the field of personal computer cooling. Small centrifugal fans are usually called turbofans. The gas flow direction of turbofans is perpendicular to the rotating shaft, while the gas flow direction of common axial fans is parallel to the rotating shaft. Compared with traditional cooling fans, centrifugal fans can output larger air volume in a smaller space, thereby improving the cooling effect. They are still often used in high-performance graphics cards, especially public version graphics card radiators.
[0003] Currently, most of the micro inner rotor turbo fans are driven by a single rotor, which has a low orbital head. In addition, the processing accuracy of the centrifugal fan blades is higher than that of ordinary fans. When the impeller is dusty or runs at high speed, the noise is also louder.
