Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device design technology, and in particular to an electronic device. Background Technology
[0002] During operation, the electronic components inside existing electronic devices generate heat. In order to keep the electronic devices at their normal operating temperature, cooling fans are generally designed inside the electronic devices to dissipate heat.
[0003] Taking a laptop as an example, a laptop generally includes a casing, a cooling fan, and internal components to be cooled (heat-generating electronic components, heat sinks, heat pipes, or heat-conducting components, etc.). The cooling fan and the components to be cooled are designed inside the casing. The casing has a first air inlet and a first air outlet, and the cooling fan has a second air inlet and a second air outlet. When the laptop is turned on, the cooling fan also starts to work. Driven by the cooling fan, the airflow outside the laptop enters the cooling fan through the first and second air inlets. At this time, the area inside the casing where the first and second air inlets are located is called the air intake channel. After the external airflow enters the cooling fan, it will be discharged from the second air outlet. The discharged airflow exchanges heat with the components to be cooled and becomes hot air, which is then discharged from the first air outlet to the outside of the electronic device. At this time, the area where the second air outlet, the components to be cooled, and the first air outlet are located is called the heat dissipation channel.
[0004] To prevent hot air from re-entering the cooling fan through the air intake channel and affecting the heat dissipation effect, existing designs typically add foam or other wind-blocking materials to the edge of the second air outlet of the cooling fan housing to block the heat dissipation channel and the air intake channel. However, although this design can prevent hot air from flowing back to the cooling fan, it requires a lot of foam material, which increases material consumption and complicates the assembly process, affecting assembly efficiency.
[0005] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

The housing has a first air inlet and a first air outlet, and the housing of the cooling fan has a second air inlet and a second air outlet. The area where the second air outlet, the component to be cooled, and the first air outlet are located constitutes a heat dissipation channel within the housing, and the area where the first air inlet and the second air inlet are located constitutes an air intake channel within the housing.

[0010] Optionally, the windproof bending portion includes a first bending portion and a second bending portion that are connected to each other;
[0011] The housing is bent towards the first air inlet at the position corresponding to the second air outlet to form the first bent portion. The first bent portion is perpendicular to the housing. The first bent portion is bent in a horizontal direction opposite to the air outlet direction of the second air outlet to form the second bent portion. The second bent portion abuts against the inner wall of the housing.
[0012] Optionally, the windproof component is a first windproof extension, and the housing extends towards the first air inlet at the position corresponding to the second air outlet to form the first windproof extension. The first windproof extension abuts against the inner wall of the housing to block the heat dissipation channel from the air inlet channel.
[0013] Optionally, the first windbreak extension also extends along the air outlet direction of the second air outlet.

[0018] Optionally, the first air outlet and the second air outlet are connected through the interior of the housing, and the component to be cooled is located between the first air outlet and the second air outlet to form the heat dissipation channel.

Detailed Implementation
[0029] This utility model discloses an electronic device to solve the technical problem that existing electronic devices use windproof materials such as foam to block heat dissipation channels and air intake channels, resulting in complex assembly and increased material consumption.
[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1 to 6 The present invention provides an electronic device comprising a housing 1, a cooling fan 2 disposed within the housing 1, and a component to be cooled. The housing 1 has a first air inlet 101 and a first air outlet 102. The housing 201 of the cooling fan 2 has a second air inlet 203 and a second air outlet 202. The area where the second air outlet 202, the component to be cooled, and the first air outlet 102 are located constitutes a heat dissipation channel 103 within the housing 1. The area where the first air inlet 101 and the second air inlet 203 are located constitutes an air intake channel 104 within the housing 1. The housing 1 or the housing 201 of the cooling fan 2 is provided with a wind-blocking component 3 for blocking the heat dissipation channel 103 and the air intake channel 104.
[0032] It should be noted that in the above-mentioned cooling fan 2, the cooling fan 2 specifically includes a fan body and a housing 201. The fan body is installed inside the housing 201. In addition, the first air inlet 101 of the electronic device and the second air inlet 203 of the cooling fan 2 overlap in the thickness direction of the housing 1 to form the air inlet channel 104. The first air outlet 102 and the second air outlet 202 are connected through the inside of the housing 1, and the component to be cooled is located between the first air outlet 102 and the second air outlet 202 to form the cooling channel 103.
[0033] In addition, the aforementioned components to be cooled can be heat-generating electronic components (CPU central processing unit or GPU graphics processing unit), heat sinks, heat pipes (heat conducting components), etc., and this utility model does not limit them.
[0034] In the electronic device of this utility model, by forming a windproof component 3 that blocks the heat dissipation channel 103 and the air inlet channel 104 directly on the outer shell 1 or the housing 201 of the cooling fan 2, the windproof effect can be achieved, while avoiding the use of auxiliary materials such as foam for windproofing, effectively saving auxiliary materials and consumables, and effectively reducing assembly difficulty and improving assembly efficiency.
[0035] Furthermore, in one embodiment, the wind deflector 3 is formed on the housing 201 at a position corresponding to the second air outlet 202.
[0036] Specifically, in one of the above embodiments, the windproof component 3 is a windproof bending portion 301. The housing 201 is bent at least once in the direction close to the first air inlet 101 at the position corresponding to the second air outlet 202 to form the windproof bending portion 301. The windproof bending portion 301 abuts against the inner wall of the housing 1 to block the heat dissipation channel 103 from the air inlet channel 104.
[0037] It should be noted that since the housing 201 of the cooling fan 2 is generally made of plastic, and plastic has a certain bending and deformation capability, the aforementioned windproof bending part 301 can be formed by bending the housing 201 of the cooling fan 2 to a certain extent, thereby blocking the hot air of the heat dissipation channel 103 and preventing the hot air from entering the air intake channel 104.
[0038] like Figure 4 As shown, in another specific embodiment of the above embodiment, the windproof bending portion 301 can be bent twice to form a windproof bending portion 301 including a first bending portion 3011 and a second bending portion 3012 that are connected to each other.
[0039] Specifically, the housing 201 is bent toward the first air inlet 101 at the position corresponding to the second air outlet 202 to form the first bent portion 3011. The first bent portion 3011 is arranged perpendicular to the housing 201. The first bent portion 3011 is bent in a horizontal direction opposite to the air outlet direction of the second air outlet 202 to form the second bent portion 3012. The second bent portion 3012 abuts against the inner wall of the outer shell 1.
[0040] It should be noted that the above design increases the contact area between the windproof bend 301 and the inner wall of the outer casing 1, thereby achieving a better blocking effect. In addition, the double-bending design also increases the structural support strength of the cooling fan 2 casing 201.
[0041] Furthermore, such as Figure 5 As shown, in the second embodiment, the windproof component 3 is specifically a first windproof extension 302. The housing 201 extends towards the first air inlet 101 at the position corresponding to the second air outlet 202 to form the first windproof extension 302. The first windproof extension 302 abuts against the inner wall of the housing 1 to block the heat dissipation channel 103 from the air inlet channel 104.
[0042] It should be noted that the first windbreak extension 302 extends outward from the housing 201 and can be formed during the injection molding process of the housing 201. Through the design of the first windbreak extension 302, a structure similar to a windbreak wall can be formed between the heat dissipation channel 103 and the air inlet channel 104 to block the hot air in the heat dissipation channel 103.
[0043] Furthermore, in one specific embodiment of the above embodiments, the first windbreak extension 302 also extends along the air outlet direction of the second air outlet 202.
[0044] It should be noted that in the above design, the extension of the first windproof extension 302 towards the air outlet 202 is equivalent to increasing the thickness of the first windproof extension 302 in the horizontal direction. The advantage of this design is that it can better block hot air from entering the air inlet channel 104. In addition, the above design can also increase the structural support strength of the cooling fan 2 housing 201.
[0045] It should also be noted that the first windbreak extension 302 in the above embodiment is specifically integrally formed with the housing 201 of the cooling fan 2.
[0046] Furthermore, such as Figure 6 As shown, in the third embodiment, the wind deflector 3 is formed on the inner wall of the housing 1 at a position corresponding to the second air outlet 202.
[0047] Specifically, the windbreak assembly 3 is a second windbreak extension 303;
[0048] The inner wall of the outer casing 1 extends toward the housing 201 at the position corresponding to the second air outlet 202 to form the second windproof extension 303, which abuts against the housing 201 of the cooling fan 2.
[0049] It should be noted that in the above design, the second windbreak extension 303 is integrally formed with the outer shell 1. The second windbreak extension 303 extends towards the outer shell 201 to form a structure similar to a windbreak wall, thereby effectively blocking the hot air from the heat dissipation channel 103 from entering the air intake channel 104.
[0050] The above provides a detailed description of an electronic device provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
