Abstract

The invention discloses a fan frame structure. The fan frame structure comprises a frame body, a base and a plurality of supporting pieces. The base is arranged in the frame body, and the plurality ofsupporting pieces are annularly arranged on the periphery of the base and are connected between the base and the frame body. Each supporting piece has a body portion and a sudden dropping portion, and the sudden dropping portions face a windward side of the frame body and are located between the body portions and the frame body. The ratio of the minimum height of the sudden dropping portions andthe maximum height of the body portions is 0.82-0.92.

Description

technical field [0001] The invention relates to a fan frame structure, in particular to a fan frame structure with a support member having a sudden drop position. Background technique [0002] The cooling modules used in general electronic devices usually use fans to take away the heat directly or indirectly, so the performance of the fans will directly affect the cooling performance of the electronic devices. When the fan is running, the airflow generated by the high-speed rotation of the fan blades will collide with the fan frame and generate running noise, which is one of the main noise sources of the fan. And because the internal flow field of the fan is very complicated, especially in the gap between the end of the fan blade and the outer frame of the frame, the air flow will produce overflow and backflow phenomena, and the flow field entering the fan frame is affected by the disturbance of the air flow, making the air flow not concentrated This in turn results in redu...
