Abstract

The invention provides a fan which comprises a fan frame and an impeller, wherein, the fan frame is provided with a body, a motor base, a plurality of stator blades and a plurality of guide components, wherein, the impeller is positioned in the body of the fan frame, and carried on by the motor base; the motor base is arranged in the body, and connected with the body by the stator blades; each stator blade is provided with a first curved surface and a second curved surface; the guide components are respectively arranged on the first curved surfaces and the second curved surfaces of the statorblades, and respectively extended from the first curved surfaces and the second curved surfaces, wherein, the plurality of guide components are arranged on each stator blade with symmetrical type or staggered type. The invention can improve the wind pressure of the fan and the characteristics of a control region, can effectively improve the characteristics of a stalled area, and can reduce the noise generated by turbulent current.

Description

technical field [0001] The invention relates to a fan and its fan frame, in particular to a high-efficiency and low-noise fan and its fan frame. Background technique [0002] With the continuous improvement of the performance of electronic devices, cooling devices or cooling systems have become one of the indispensable equipment in current electronic devices, because if the heat energy generated by electronic devices is not dissipated properly, the performance will deteriorate at least, and the serious It may cause burning of the electronic device. Heat dissipation devices are even more important for microelectronic components (such as integrated circuits, integrated circuits), because with the increase in integration and the advancement of packaging technology, the area of ​​integrated circuits is continuously shrinking, and the heat energy accumulated per unit area It will also be relatively higher, so heat dissipation devices with high heat dissipation efficiency have al...
