Embodiment Construction

[0044] Please refer to Figure 1A to Figure 1C , the fan module 10 disclosed in the first embodiment of the present invention includes a noise reduction device 100 and a fan 200, the noise reduction device 100 includes a first noise reduction component 120, the first noise reduction component 120 can be made of porous material, or other The first sound-absorbing component 120 is made of a sound-absorbing material with a porous structure. In this embodiment, foam is used as an example to illustrate the material of the first noise reduction component 120 , but it is not limited thereto. A first air flow channel 122 is formed in the first sound attenuation assembly 120 through the first sound attenuation assembly 120, and on the wall surface of the first sound attenuation assembly 120 located in the first air flow channel 122, a recess is formed on the wall surface and communicates with the first air flow channel 122. A buffer space 124 of the airflow channel 122 is used to incr...

Abstract

The invention relates to a fan module which comprises a fan and a silencing device which is arranged on the fan. The silencing device comprises a first silencing assembly, the first silencing assembly is attached to one side o the fan, an airflow passage corresponds to an air port of the fan, and the first silencing assembly is made of porous materials to absorb winding cutting sound or vibration generated in fan operation to reduce the noise generated in the fan operation.

Description

【Technical field】 [0001] The invention relates to a fan module, in particular to a fan module of an electronic device. 【Background technique】 [0002] In the field of heat dissipation of electronic components, fans are often used in the field of heat dissipation due to the fact that the technical threshold for making fans is not high, and they have the advantages of low price, high reliability and high durability. The fan uses the rotation of its fan blades to exert pressure on the air to cause air flow, and through the flowing air to reduce the temperature around the fan by forced convection, thereby achieving the cooling effect. However, when the fan blades disturb the air, the fan blades will rub against the air, which will generate a wind cutting sound at the edge of the fan blades. In addition, when the air flows through the air inlet or outlet of the fan, it will Airflow noise caused by friction with the frame. [0003] Although, when the rotating speed of the fan bl...
