Abstract

A heat dissipating module with silencing function is composed of a heat dissipating fin module and a centrifugal fan for dissipating the heat of fin. Said centrifugal fan has a motor, the centrifugal blades fixed to the rotor of motor and a casing, and features that the hair structure is arranged on the inner surface of the air outlet of said casing for eliminating noise. Said heat dissipating fin module has heat dissipating fins close to the heating object, an airflow channel with hair structure on its inner surface and a casing.

Description

technical field

[0001] The invention relates to a centrifugal fan and a heat dissipation module, in particular to a heat dissipation module with a sound-absorbing function for a computer. Background technique

[0002] As the computer responds to the market demand for thinner computers, it is no longer possible to reserve enough natural convection space inside the notebook computer casing for the structure required by the heat dissipation design. Especially in high-frequency components (such as central processing units and graphics chips), they have already faced considerable bottlenecks in the implementation of thermal design. Therefore, using a centrifugal fan to generate forced convection heat dissipation has become the main structure of the notebook computer heat dissipation mechanism.

[0003] Centrifugal fan 100 utilizes the flow path design of the curved surface of the volute casing to gradually expand (such as figure 1 As shown), the centrifugal fan blade 103 conver...
