DETAILED DESCRIPTION

[0045] The present invention discloses an electronic device, which is used to solve the technical problem that the cooling fan of the existing electronic device generates a large noise during operation.

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] See also Figures 1 to 16 An electronic device provided by an embodiment of the present invention includes a device housing 1 and a cooling fan 2 arranged in the device housing 1, the cooling fan 2 includes a fan housing and a fan body 206 arranged in the housing, the device housing 1 is provided with an air inlet and an air outlet 101, the fan body 206 is configured to generate an airflow introduced from the air inlet and discharged to the air outlet 101, and a sound absorbing structure 5 is provided at a position of the device housing 1 corresponding to the flow path of the airflow.

[0048] It should be noted that the specific flow path of the airflow generated by the cooling fan 2 in this embodiment is:

[0049] Driven by the fan body 206 , the airflow outside the device housing 1 enters the interior of the device housing 1 from the air inlet, then enters the fan housing and flows out from the fan housing to the air outlet 101 .

[0050] In the electronic device of this embodiment, the fan body 206 is configured to generate an airflow drawn from the air inlet and discharged toward the air outlet 101. Furthermore, a sound-absorbing structure 5 is provided at a position on the device housing 1 corresponding to the airflow path. Through this design, the sound-absorbing structure 5 absorbs the noise generated by the cooling fan 2 during operation, thereby reducing the noise generated by the cooling fan 2. Furthermore, this design eliminates the need to redesign the fan body 206. Under low power consumption conditions, constant rotation speed, and constant air flow, the cooling fan 2 generates lower noise, improving the user experience. Under high power consumption conditions, when noise levels are constant, a higher rotation speed and increased air flow are achieved.

[0051] Furthermore, the fan housing in this embodiment is provided with a first notch portion 4 at a position corresponding to the flow path of the airflow;

[0052] The sound absorbing structure 5 is filled in the first notch 4 .

[0053] It should be noted that the first notch 4 in this embodiment is formed by cutting the fan housing without affecting its structure. Its specific shape is selected based on design requirements and is not limited in this embodiment. Furthermore, the sound-absorbing structure replaces part of the fan housing, achieving sound absorption and noise reduction without affecting the operation of the cooling fan 2. In addition to the sound-absorbing effect, the sound-absorbing structure replaces part of the original fan housing, which helps reduce the weight of the device.

[0054] Furthermore, the fan housing in this embodiment includes a first housing 201, a second housing 202, and a third housing 203 for connecting the first housing 201 and the second housing 202. The first housing 201, the second housing 202, and the third housing 203 form the fan housing.

[0055] The third housing 203 is provided with an air outlet 205 corresponding to the air outlet 101, and the first housing 201 and / or the second housing 202 are provided with an air inlet 204 corresponding to the air inlet at a position corresponding to the fan body 206, and a heat dissipation fin 3 is further provided between the air outlet 205 and the air outlet 101;

[0056] An air guide channel 207 is provided in the fan housing;

[0057] One end of the air guiding channel 207 is connected to the air inlet 204 , and the other end of the air guiding channel 207 is connected to the air outlet 205 .

[0058] It should be noted that in the above design, since the fan housing is provided with an air inlet 204, an air guide channel 207, and an air outlet 205, when the cooling fan 2 is running, driven by the fan body 206, the airflow outside the device housing 1 enters the interior of the device housing 1 from the air inlet, and then enters the fan housing through the air inlet 204. After flowing in the air guide channel 207, the airflow flows out of the device housing 1 from the air outlet 205, and finally flows out of the device housing 1 from the air outlet 101.

[0059] Furthermore, if Figure 4 and Figure 5 As shown, in the first specific embodiment, the first notch portion 4 is opened at a position of the first shell 201 and / or the second shell 202 corresponding to the air outlet 205 , and the heat dissipation fins 3 are pressed against the sound absorbing structure 5 .

[0060] It should be noted that since the airflow from the air outlet 205 passes through the heat sink fins 3 and then flows out of the air outlet 101, it will collide with the heat sink fins 3 during the flow process and flow back to the air outlet 205 of the fan housing, thereby colliding with the fan housing at the location of the air outlet 205, thereby generating noise. Therefore, by providing a sound-absorbing structure 5 in the device housing 1 at a position corresponding to the first notch 4, the sound-absorbing structure 5 can effectively absorb this noise, thereby reducing noise.

[0061] Furthermore, in the above design, the heat dissipation fins 3 press against the sound absorbing structure 5 to ensure that the sound absorbing structure 5 can fit closely with the inner wall of the device housing 1 , thereby preventing the sound absorbing structure 5 from interfering with the airflow of the air outlet 205 .

[0062] like Figures 6 to 9 As shown, in the second specific embodiment, the first notch portion 4 is opened at a position of the first shell 201 and / or the second shell 202 corresponding to the air guide channel 207 .

[0063] It should be noted that when the airflow flows in the air guide channel 207, the airflow will also collide with the first shell 201 and / or the second shell 202, thereby generating noise. Therefore, through the above design, the noise generated by the airflow passing through the air guide channel 207 can be effectively absorbed, thereby reducing the noise.

[0064] like Figures 10 to 13 As shown in the third specific embodiment, the first notch portion 4 is opened at a position of the third shell 203 corresponding to the air guide channel 207 .

[0065] It should be noted that when the airflow flows through the air guide channel 207, the airflow will collide with the third shell 203 and generate noise. Therefore, through the above design, the noise generated by the airflow passing through the air guide channel 207 can be effectively absorbed, thereby reducing the noise.

[0066] In addition, in the above specific embodiment, a support portion 6 is further provided on the device housing 1 . The support portion 6 is provided corresponding to the first notch portion 4 and the sound absorbing structure is attached to the support portion 6 .

[0067] It should be noted that since the third shell 203 is specifically arranged perpendicular to the first shell 201 and the second shell 202, in order to enable the sound-absorbing structure 5 to stably fill the above-mentioned first notch 4, this embodiment designs a support part 6 for supporting the sound-absorbing structure 5 at the position corresponding to the first notch of the device shell 1.

[0068] Specifically, the support portion 6 can be a plastic bracket, a rubber block, a silicone block, etc., which is not limited in this embodiment.

[0069] Furthermore, if Figure 14 and Figure 15 As shown, in the fourth specific embodiment, a second notch portion 7 is provided at a position of the device housing 1 in this embodiment corresponding to the air inlet hole 204, and preferably, the shape of the second notch portion 7 matches the shape of the air inlet hole 204;

[0070] The sound absorbing structure 5 is filled in the second notch 7 , and can be filled in the second notch 7 by gluing or other methods.

[0071] It should be noted that when the cooling fan 2 is operating, air flows from the air inlet into the device housing 1, then passes through the air inlet hole 204 and into the air guide channel 207 within the fan housing. During this process, the airflow collides with the fan housing as it passes through the air inlet hole 204, generating noise. Therefore, through the above design, this embodiment provides a second notch 7 at the location of the device housing 1 corresponding to the air inlet hole 204, and a sound-absorbing structure 5 is attached to the second notch 7. This sound-absorbing structure 5 can absorb this noise, thereby reducing it.

[0072] In addition, it should be noted that the above-mentioned second notch portion 7 is obtained by cutting the device housing 1 without affecting the structure of the device housing 1. Its specific shape is selected according to design requirements, and this embodiment does not limit this.

[0073] Furthermore, the electronic device in this embodiment may specifically be a laptop computer, which may further include a display screen;

[0074] The device housing 1 has a rotating shaft portion 102. In this embodiment, the rotating shaft portion 102 is regarded as a part of the device housing 1.

[0075] The display screen is connected to the rotating shaft portion 102 so as to be driven to rotate relative to the device housing 1 .

[0076] like Figure 16 As shown, in the fifth specific implementation, the air outlet 101 in this embodiment is provided corresponding to the shaft portion 102 , and the sound absorbing structure 5 is attached to the position of the shaft portion 102 corresponding to the air outlet 101 .

[0077] It should be noted that since the airflow ultimately flows out of the device housing 1 through the air outlet 101, during this flow process, the airflow collides with the rotating shaft 102, generating backflow. This backflow impacts the device housing 1 where the air outlet 101 is located, generating noise. Therefore, through the above design, the sound-absorbing structure 5 is placed at the position corresponding to the rotating shaft 102 and the air outlet 101 to effectively absorb this noise and thus reduce noise.

[0078] Furthermore, the rotating shaft portion 102 in this embodiment is provided with a groove recessed therein, and the sound absorbing structure 5 is filled in the groove and the outer surface thereof is flush with the outer wall surface of the rotating shaft portion 102 .

[0079] It should be noted that, through the above design, while achieving the sound absorption effect, the flatness of the outer wall surface of the shaft portion is also ensured.

[0080] Furthermore, the sound absorbing structure 5 in this embodiment is a sound absorbing material;

[0081] Wherein, the sound absorbing material is a porous sound absorbing material.

[0082] It should be noted that the porous sound-absorbing material may be a sound-absorbing foam material or a nano-porous sound-absorbing material. The porous sound-absorbing material is a prior art and will not be elaborated in detail in this embodiment.

[0083] Furthermore, to prove that the electronic device in this embodiment has the effect of reducing the noise of the cooling fan 2, an experimental example will be used to illustrate in detail as follows:

[0084] Experimental example:

[0085] Object 1: The same electronic device as the one in the prior art without any improvements.

[0086] Object 2: An electronic device adopting the first specific implementation of the above embodiment, specifically, a first notch portion 4 is opened at a position corresponding to the air outlet 205 of the second shell 202 of the cooling fan 2, and a sound absorbing structure 5 is provided on the first notch portion 4.

[0087] The measured comparison data are as follows:

[0088]

[0089] Measured data shows that, at the same SPL, system flow in Object 2 increased by 5.1% and air pressure by 7%. This demonstrates that these improvements, while maintaining constant speed and air flow, produce lower noise, improving user experience. Furthermore, at high power consumption and constant noise levels, higher speeds are achieved, increasing air flow.

[0090] The above is a detailed introduction to an electronic device provided by the present invention. For those skilled in the art, according to the concept of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
