Embodiment Construction

[0046] See Figure 1 to Figure 2 . figure 1 It is a perspective view of the fan device disclosed according to the first embodiment of the present invention. figure 2 for figure 1 Cutaway view.

[0047] In the fan device 1 of this embodiment, the fan device 1 is, for example, a centrifugal fan, and is applied to electronic devices such as a notebook computer, for example. The fan device 1 includes a casing 10, a fan blade 20 and a silencer groove 40.

[0048] The housing 10 is made of a plastic hard material, for example, and has an air inlet 11, an air outlet 12, an accommodating space 13 and a bypass 14 communicating with each other. In detail, the housing 10 includes a top plate 15, a bottom plate 16 and a side wall 17, and the top plate 15 and the bottom plate 16 are connected to opposite sides of the side wall 17. The air inlet 11 is located on the top plate 15, and the top plate 15, the bottom plate 16 and the side wall 17 jointly surround the accommodation space 13 and for...

Abstract

The invention discloses a fan device. The fan device comprises a shell, a fan blade and a silencing groove body, wherein the shell is provided with an air inlet, an air outlet, a containing space anda bypass opening which communicate with one another, the fan blade is arranged in the containing space, the silencing groove body is arranged at the position of the bypass opening and is located outside the containing space, the silencing groove body is provided with an airflow channel, and the airflow channel communicates with the containing space through the bypass opening. According to the fandevice, the fan blade sucks air through the air inlet, air flow is generated in the containing space, so that the air flow passes through the bypass opening to enter the airflow channel.

Description

Technical field [0001] The present invention relates to a fan device, in particular to a fan device with a sound-absorbing groove. Background technique [0002] With the advancement and development of technology, the performance of electronic devices (such as desktop computers, notebook computers, or servers) has been significantly improved. However, with the development of high-efficiency electronic devices, a large amount of heat generation is accompanied by the increase in the internal temperature of the electronic devices and affects the performance of the electronic devices. Therefore, the current heat dissipation methods of electronic devices mostly rely on cooling fans. Heat dissipation. [0003] However, the cooling fan of the electronic device generates noise due to its blade passing frequency, which reduces the user experience. Generally speaking, the method to solve the noise generated by the fan is to modify the shape of the fan blade or the shape of the internal flow...
