Embodiment Construction

[0013] In order to solve the dilemma of noise and heat dissipation, the present invention proposes a heat dissipation module with a noise reduction function. In the present invention, an uneven structure is designed in the flow channel of the heat dissipation module (for example, the heat dissipation module of heat dissipation fins) to reduce noise.

[0014] Please refer to figure 2 , which shows a schematic diagram of a heat dissipation module with noise reduction function according to a preferred embodiment of the present invention. This embodiment includes a centrifugal fan 100 and a cooling fin module 110 . The centrifugal fan 100 has a centrifugal blade 103 . The motor (not shown) in the centrifugal fan 100 drives the centrifugal fan blade 103 , so that air is taken in through the air inlet 102 , passes through the volute channel 105 in the fan, and finally exits through the air outlet 104 . Due to the friction between the fluid and the tube wall in the spiral channel...

Abstract

The heat sink module with sound silencing function includes one separated finned heat dissipating assembly and one centrifugal fan. The centrifugal fan to output airflow to the finned heat dissipating assembly for removing its heat includes centrifugal vanes fixed onto the rotor of one motor, and one shell for the motor and centrifugal vanes to be fixed inside it. The finned heat dissipating assembly includes one finned block near the heat dissipating target and one head dissipating flow channel casing with the finned heat dissipating block and the heat dissipating target inside it, and the inner wall of the flow channel has sound silencing uneven structure.

Description

technical field [0001] The invention relates to a heat dissipation module, in particular to a heat dissipation module with a sound attenuation function. 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 space required by the heat dissipation design. Especially in high-frequency components (such as central processing unit and graphics chip), it has already faced a considerable bottleneck in the execution of heat dissipation 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 10 is to utilize the flow passage design (such as figure 1 As shown), the centrifugal fan blade 16 converts gas kinetic energy into pressure energy to obtain a better static pressure to overcome the hi...
