Embodiment Construction

[0028] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings.

[0029] see figure 1 , figure 2 , is a perspective view of the fan frame structure of the present invention, as shown in the figure, a fan frame structure 2 includes a frame body 27, the frame body 27 has a bottom surface 20, a top surface 21 and a flow channel 22, the The flow channel 22 is arranged between the bottom surface 20 and the top surface 21, and the flow channel 22 faces an inner wall 23 of the frame body 27. The bottom surface 20 and the top surface 21 respectively have an outlet 24 and a The inlet 25 communicates with the flow channel 22 .

[0030] In the flow channel 22 of the aforementioned frame body 27, a fan wheel 5 is correspondingly pivoted, and the structure of the fan wheel 5 is the structure of the existing fan wheel (with a hub, and the outer peripheral s...

Abstract

The invention provides a fan frame structure. The fan frame structure comprises a frame body which is provided with a bottom face, a top face and a flow pass; and the flow pass is formed between the bottom face and the top face, the bottom face is provided with an outlet, the top face is provided with an inlet, and the outlet and the inlet communicate with the flow pass, wherein the outlet is provided with an outlet edge, and the outlet edge is provided with a plurality of grooves which communicate with the flow pass. Through the structural design of the grooves, the noise problem generated during fan operation is greatly relieved.

Description

technical field [0001] The invention relates to a fan frame structure, in particular to a fan frame structure which can greatly reduce the noise generated when the fan is running. Background technique [0002] With the rapid development of electronic products towards high performance, high frequency, high speed and thinness, the heating temperature of electronic products is getting higher and higher, which is prone to instability and affects product reliability and service life. Therefore, heat dissipation has become a One of the important issues of electronic products is to effectively dissipate heat. At present, the cooling airflow generated by the fan is used for forced heat dissipation, so as to dissipate the heat. [0003] The principle of the cooling airflow generated by the fan is nothing more than relying on the design of the fan blades on the rotor, driving the rotor through the motor and the circuit board, so that the rotor rotates at a rated speed, and the rotatin...
