Description

electronic devices Technical Field

[0001] This application belongs to the field of communication equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Currently, electronic devices such as mobile phones and tablets are becoming smaller and more powerful, but they are also generating more heat, thus increasing the demand for heat dissipation. Generally speaking, electronic devices mostly use passive cooling methods, which dissipate heat from high-heat-generating parts of the device through thermally conductive materials.

[0003] However, while passive cooling can maintain a certain level of heat dissipation when electronic devices are used at low power consumption, its effectiveness is insufficient when the device is used at high power consumption, leading to sluggish operation or even overheating. Therefore, the heat dissipation performance of electronic devices in related technologies is generally poor. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that can solve the technical problem of poor heat dissipation performance of electronic devices.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: This application discloses an electronic device, including: a housing, the housing having a first air inlet channel, a second air inlet channel, and an air outlet channel communicating with the external environment, the air outlet channel being opened on the side wall of the housing, and the first air inlet channel and the second air inlet channel being opened on the side of the housing adjacent to the side wall; a fan, the fan being located inside the housing, the fan having an air inlet and an air outlet, the first air inlet channel and the second air inlet channel being connected to the air inlet, and the air outlet channel being connected to the air outlet.

[0006] In this embodiment, the outer casing is provided with a first air inlet channel and a second air inlet channel, and the fan's air inlet is connected to both the first and second air inlet channels. The fan drives external airflow into the outer casing through the first and second air inlet channels, and after heat exchange, it is discharged through the air outlet channel. In this design, the fan enables rapid convection between the external ambient airflow and the internal airflow of the electronic device, allowing for rapid heat dissipation. Simultaneously, the outer casing has two air inlet channels, enabling dual-channel air intake and increasing the fan's airflow volume, thereby effectively improving the overall heat dissipation efficiency. Therefore, the electronic device disclosed in this application has good heat dissipation performance. Attached Figure Description

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0012] Please refer to Figures 1 to 11. This application discloses an electronic device, which includes a housing 100 and a fan 400.

[0013] The housing 100 serves as the external appearance component of the electronic device and also provides a mounting base for other components of the electronic device. The housing 100 has an internal cavity, which is the space within the housing 100 used to mount functional devices of the electronic device. For example, circuit boards, camera assemblies, and other components of the electronic device are mounted within the internal cavity. The housing 100 has a first air inlet channel 101, a second air inlet channel 102, and an air outlet channel 103, all of which communicate with the external environment. The external environment refers to the external space of the housing 100. The first air inlet channel 101, the second air inlet channel 102, and the air outlet channel 103 are spaced apart on the housing 100. Each of the three channels communicates with both the external environment and the internal cavity; therefore, they are three independent channel structures.

[0014] An air outlet duct 103 is formed on the side wall of the housing 100. The side wall of the housing 100 is the side edge of the housing 100, which can also be understood as the outer peripheral surface of the housing 100. Therefore, one end of the air outlet duct 103 penetrates the outer peripheral surface of the housing 100. The first air inlet duct 101 and the second air inlet duct 102 are formed on the side of the housing 100 adjacent to its side wall. The side of the housing 100 adjacent to its side wall is the back or front of the housing 100. Here, the front can be understood as the surface of the housing 100 on the side where the display screen 200 is located, or the side of the electronic device facing the user. The back can be understood as the surface of the housing 100 away from the display screen, or the side of the electronic device away from the user.

[0015] The fan 400 is located inside the housing 100. The fan 400 has an air inlet 401 and an exhaust outlet 402. Both the first air inlet channel 101 and the second air inlet channel 102 are connected to the air inlet 401. At this time, ambient air enters the housing 100 through the first air inlet channel 101 and the second air inlet channel 102, respectively. The exhaust outlet channel 103 is connected to the exhaust outlet 402. The cold air from the external environment and the hot airflow inside the housing undergo convective heat exchange, thereby exhausting the heat inside the electronic device through the exhaust outlet channel 103 to the outside of the electronic device, thus completing the heat dissipation of the electronic device.

[0016] Optionally, as shown in Figure 11, the fan 400 may include a fan housing, fan blades, and a drive source. The drive source is disposed on the fan housing, which has a flow channel. The fan blades are disposed within the flow channel. The drive source can drive the fan blades to rotate. During the rotation of the fan blades, the airflow within the flow channel can be driven to flow, thereby realizing convection between the external environment and the airflow in the internal cavity. One end of the flow channel is the aforementioned air inlet 401, and the other end is the aforementioned exhaust port 402.

[0017] In another alternative embodiment, the fan 400 may consist only of fan blades and a drive source, with the flow channel formed within the inner cavity. That is, the housing 100 and the fan casing are a single, integrated structure. The specific structure and principle of the fan 400 in this application are well-known technologies and are not intended to limit the scope of the application.

[0018] In the specific working process, under the action of the fan 400, the cold air from the outside enters the outer casing 100 through the first air inlet channel 101 and the second air inlet channel 102 respectively. After heat exchange inside the outer casing 100, it is discharged to the outside of the outer casing 100 through the air outlet channel 103.

[0019] The heat source of the electronic device in this application can be located between the air inlet 401 and the exhaust port 402, or it can be located between the exhaust port 402 and the air outlet 103. The heat source refers to the heat-generating component inside the electronic device, and the specific location of the heat source is not limited herein.

[0020] In the embodiments disclosed in this application, the outer casing 100 is provided with a first air inlet channel 101 and a second air inlet channel 102, and the air inlet 401 of the fan 400 is connected to both the first air inlet channel 101 and the second air inlet channel 102. At this time, the fan 400 drives external airflow into the outer casing 100 through the first air inlet channel 101 and the second air inlet channel 102, and then, after heat exchange, exhausts it through the air outlet channel 103. In this application, the fan 400 can achieve rapid convection heat exchange between the external ambient airflow and the internal airflow of the electronic device, thereby enabling the heat from the electronic device to be quickly dissipated. Therefore, compared with the passive heat dissipation methods in related technologies, the heat dissipation method in this application has higher heat dissipation efficiency and thus better heat dissipation performance. Therefore, the electronic device disclosed in this application has better heat dissipation performance.

[0021] In addition, the outer casing 100 has two air intake channels, which enables dual-channel air intake, thereby increasing the air intake of the fan 400 and effectively improving the overall heat dissipation efficiency.

[0022] In addition, a dual-channel design with a first air intake channel 101 and a second air intake channel 102 is adopted to form physical redundancy. When one channel is blocked due to dust, foreign objects or environmental factors, the other channel can still work independently to ensure that the fan 400 continues to intake air, avoiding the risk of interruption of heat dissipation, overheating shutdown or burnout of electronic equipment due to blockage of a single channel.

[0023] Furthermore, the first air inlet channel 101 and the second air inlet channel 102 are located on the adjacent side of the air outlet channel 103, thereby making the first air inlet channel 101 and the second air inlet channel 102 spatially misaligned with the air outlet channel 103, forming a physical isolation effect, effectively preventing the risk of the discharged hot air being re-inhaled by the fan 400, avoiding airflow short circuit, and ensuring the effectiveness of heat dissipation.

[0024] At the same time, the air inlet channel and the air outlet channel 103 are not on the same plane, which makes the internal air duct layout of the housing 100 more regular, the fan 400 is installed with more uniform force, and reduces resonance and noise caused by airflow impact.

[0025] The electronic device disclosed in this application, by setting up dual air intake channels, not only expands the air intake area and improves the air intake efficiency, but more importantly, provides redundancy protection, effectively avoiding the technical pain point of single channel being prone to blockage and causing equipment failure; at the same time, with the staggered layout of the adjacent air outlet channel 103 and air intake channel, the backflow interference is completely eliminated, and finally a comprehensive technical effect of efficient heat dissipation, low noise and stability, and anti-blockage reliability is achieved.

[0026] In one embodiment, as shown in Figures 1 and 2, the outer casing 100 may include a decorative element 120 and a housing 110. The housing 110 may include a back cover 111 and a frame 112. The frame 112 extends along the edge of the back cover 111, and here the frame 112 is the side wall of the outer casing 100. Therefore, the air outlet duct 103 can be formed on the frame 112. The back cover 111 of the housing 110 is located on the side of the housing 110 away from the display screen 200. Here, the back cover 111 can also be understood as a battery cover. The decorative element 120 can be disposed on the back cover 111. The fans 400 are all located inside the housing 110. The first air inlet duct 101 and the second air inlet duct 102 can be simultaneously formed on the back cover 111 of the housing 110; or, the first air inlet duct 101 and the second air inlet duct 102 can be simultaneously formed on the decorative element 120. Of course, one of the first air intake channel 101 and the second air intake channel 102 can be opened on the rear cover 111 of the housing 110, and the other can be opened on the decorative part 120.

[0027] In this design, the first air intake channel 101 and the second air intake channel 102 are both located on the side of the housing 110 away from the display screen 200. Therefore, the first air intake channel 101 and the second air intake channel 102 are both located on the side away from the user, avoiding the risk of the user's face blocking the first air intake channel 101 and the second air intake channel 102 when making or receiving calls.

[0028] Furthermore, at least a portion of the decorative element 120 is positioned opposite to the fan 400; the first air intake channel 101 is positioned opposite to the air inlet 401, and the second air intake channel 102 is formed on the decorative element 120. Firstly, with the first air intake channel 101 opposite to the air inlet 401, external air enters through the first air intake channel 101 and enters the fan 400's air inlet 401 directly in a straight line without turning, bending, or obstruction. This avoids eddies, turbulence, and pressure losses caused by airflow turning within the housing 110, thereby minimizing intake resistance and maximizing the fan 400's working efficiency. Secondly, the first air intake channel 101 opposite to the air inlet 401 ensures that the amount of air entering the fan 400 per unit time is maximized, directly improving heat dissipation and ventilation capabilities. Therefore, the first air intake channel 101 opposite to the air inlet 401 achieves "direct-blow" air intake, maximizing intake efficiency and eliminating airflow loss.

[0029] Furthermore, the second air intake channel 102 on the decorative component 120 faces the fan 400, allowing the two airflows to precisely converge in the central area of ​​the fan 400, forming a stable and concentrated airflow field. This prevents airflow dispersion and avoids airflow dispersion and mutual interference caused by the oblique entry of airflow into the second air intake channel 102, ensuring uniform force on the fan blades of the fan 400 and reducing operational vibration and noise. In addition, utilizing the space between the decorative component 120 and the fan 400 as an air intake buffer eliminates the need for additional internal space in the housing 110, resulting in a more compact structure.

[0030] In this design, one air intake channel faces the air inlet 401 to form the main air intake, and another air intake channel faces the fan 400 to form the auxiliary air intake. The main air intake and the auxiliary air intake form a dual-source direct blowing, which completely solves the risks of insufficient single-path air intake and uneven force on the fan 400 caused by airflow deviation. This ensures that both airflows reach the fan 400 in a straight line, with the shortest air intake path, the least resistance, and the most stable airflow, achieving a highly efficient and low-noise air intake effect.

[0031] In an optional embodiment, as shown in Figures 1 to 4, the electronic device may further include a camera module 800, which is disposed within the housing 110. The camera module 800 is located directly below the decorative element 120 and is arranged side-by-side with the fan 400. A portion of the fan 400 is located directly below the decorative element 120. In this case, since the camera module 800 is located directly below the decorative element 120, the decorative element 120 serves to both conceal and decorate the camera module 800; therefore, the decorative element 120 is a camera decorative element. Specifically, a first air inlet channel 101 is formed on the housing 110, and a second air inlet channel 102 is formed in the area of ​​the decorative element 120 directly opposite the fan 400.

[0032] In this design, the fan 400 is located directly below the decorative element 120, adjacent to the second air intake channel 102. External cold air can be directly and unobstructedly drawn into the fan 400, preventing airflow from meandering within the housing 110, reducing energy loss, and ensuring the fan 400 operates at maximum efficiency. Furthermore, placing the camera module 800 and fan 400 side-by-side directly below the decorative element 120 achieves efficient utilization and rational partitioning of the limited space within the housing 110. This avoids stacking the camera module 800 and fan 400 in the depth direction, effectively reducing the overall thickness and achieving a slimmer design. In addition, their side-by-side arrangement results in a neat internal structure, providing more ample installation space for other components such as the motherboard and battery.

[0033] In one embodiment, as shown in FIG6, the decorative element 120 may have a first surface 120a facing away from the fan 400, and one end of the second air intake channel 102 facing away from the air inlet 401 penetrates through the first surface 120a. The side of the decorative element 120 facing the fan 400 is the side of the decorative element 120 facing the inner cavity, which can be understood as the bottom surface of the decorative element 120, and the side of the decorative element 120 facing away from the fan 400 and the inner cavity can be understood as the top surface of the decorative element 120. Here, the first surface 120a is the top surface of the decorative element 120, and at this time, one end of the second air intake channel 102 penetrates through the top surface of the decorative element 120, so the decorative element 120 is a top surface air intake. At this time, the second air intake channel 102 can penetrate from the top surface of the decorative element 120 through its bottom surface.

[0034] In this design, the second air intake channel 102 directly penetrates the top and bottom surfaces of the decorative component 120, allowing external cold air to reach the fan 400 vertically. The airflow path is unobstructed and has minimal wind resistance, significantly improving airflow and heat dissipation efficiency.

[0035] In another alternative embodiment, as shown in Figures 1 to 3, the decorative element 120 may have a first surface 120a facing away from the fan 400 and a first side surface 120b extending circumferentially along the first surface 120a. One end of the second air intake channel 102 facing away from the air intake port 401 penetrates through the first side surface 120b. In this case, the end of the second air intake channel 102 that communicates with the external environment is located on the first side surface 120b of the decorative element 120, which is the outer wall of the decorative element 120. At this time, the end of the second air intake channel 102 that communicates with the external environment is located on the side of the decorative element 120, not on the top surface of the decorative element 120.

[0036] In this design, the port of the second air intake channel 102 that connects to the external environment is hidden in the side wall of the decorative component 120. This keeps the top surface of the decorative component 120 intact, smooth, and without openings, thus solving the problem of openings on the top surface of the decorative component 120 disrupting its overall appearance. Simultaneously, because the port of the second air intake channel 102 that connects to the external environment is hidden in the side wall of the decorative component 120, the second air intake channel 102 is not visible from the front view of the decorative component 120, thereby improving the consistency and aesthetics of the electronic device's appearance.

[0037] In addition, the side openings of the decorative part 120 are far from its top surface, which effectively prevents dust, liquids and debris from falling vertically into the second air intake channel 102, greatly reducing the risk of fan 400 blockage, extending the life of the heat dissipation system and further improving the reliability of electronic equipment.

[0038] In addition, the side air intake changes the airflow direction, avoiding the risk of local temperature difference or condensation caused by direct airflow from the top surface, improving the safety of use, and avoiding the risk of fogging on the top surface of the decorative part 120.

[0039] In the embodiments disclosed in this application, the port of the second air inlet channel 102 that connects to the external environment is hidden on the side of the decorative part 120, achieving an extremely beautiful top surface without holes, while enhancing dustproof and waterproof capabilities and structural strength, thus balancing aesthetics and durability.

[0040] Further, as shown in Figure 3, the second air intake channel 102 may include a first section 1021 and a second section 1022. One end of the first section 1021 penetrates the first side surface 120b, and the first section 1021 is connected to the air intake 401 through the second section 1022. The axial direction of the first section 1021 intersects the axial direction of the second through hole 1112. In this design, the axes of the first section 1021 and the second section 1022 intersect, requiring the airflow to bend before entering the fan 400. This effectively prevents vertically falling dust, water droplets, and debris from directly entering the inner cavity, significantly improving the dustproof and waterproof capabilities of the electronic device. In addition, because the second air intake channel 102 is bent, the internal fan 400 or camera module 800 cannot be directly seen from the side opening of the decorative part 120, maintaining the exquisite appearance of the side opening of the decorative part 120 while eliminating the risk of exposed internal components. In addition, the airflow is buffered and turbulent at the corner, which weakens the howling or high-frequency noise generated by direct airflow, and helps to further reduce the noise generated when electronic devices are dissipating heat.

[0041] This article discloses a specific structure of a decorative component 120. Of course, the decorative component 120 can also have other structures, which are not limited herein. Specifically, as shown in Figure 3, the decorative component 120 may include a lens 121, a support 122, and a bracket 123. The lens 121, support 122, bracket 123, and back cover 111 are stacked sequentially. The surface of the lens 121 facing away from the support 122 can be the aforementioned first surface 120a, and the outer peripheral surface of the bracket 123 can be the first side surface 120b. The second air inlet channel 102 can be formed on the bracket 123. Specifically, the lens 121 is responsible for appearance display and optical protection, keeping the top surface smooth and intact, and does not participate in heat dissipation openings, ensuring the visual purity of the camera area. The support 122, as an intermediate layer, is responsible for positioning and transition, connecting the lens 121 and the bracket 123 to ensure assembly accuracy. The bracket 123, as the main structural body and heat dissipation carrier, undertakes the function of forming the second air inlet channel 102.

[0042] This design achieves separation between the "appearance" and "functionality," ensuring they do not interfere with each other, thus guaranteeing both aesthetic performance and heat dissipation. Furthermore, the multi-layered composite structure formed by the lens 121, the support 122, and the bracket 123 offers greater impact and deformation resistance compared to a single-layer structure. The bracket 123, as the bottom layer, physically isolates the heat dissipation channel 301 from internal precision components, preventing stress from the opening from being transmitted to the fragile lens 121, thereby improving the safety and reliability of the electronic device. Additionally, if the bracket 123 is damaged or the second air intake channel 102 is blocked, the bracket 123 can be disassembled and replaced separately without disassembling the entire decorative component 120, reducing after-sales maintenance costs.

[0043] In the above design, the housing 110 has a mounting hole (not shown in the attached diagram), and the decorative piece 120 can cover the mounting hole. The camera module 800 is positioned opposite the mounting hole, which exposes the lens of the camera module 800. The end of the second air intake channel 102 facing the fan 400 can be connected to the air intake 401 of the fan 400 through the mounting hole. In this case, the mounting hole not only exposes the camera module 800 but also a portion of the air intake 401 of the fan 400 to ensure that the end of the second air intake channel 102 facing the fan 400 is connected to the air intake 401 of the fan 400 through the mounting hole.

[0044] In another optional embodiment, a first through hole 1111 is provided in the area opposite to the mounting hole on the back cover 111 and the decorative piece 120. The first through hole 1111 is opposite to the air inlet 401, and the second air intake channel 102 can be connected to the air inlet 401 through the first through hole 1111. In this solution, external air flows only through the path of the second air intake channel 102, the first through hole 1111, and the air inlet 401 of the fan 400, without passing through the area where the camera module 800 is located. This cuts off the path for dust and moisture to be blown directly to the lens of the camera module 800 with the airflow, avoiding dust accumulation and fogging on the lens, ensuring that the lens of the camera module 800 maintains high-definition imaging for a long time without the need for frequent cleaning. In addition, the first through hole 1111 is set independently and parallel to the mounting hole, so the heat dissipation airflow will not interfere with the optical performance of the lens, nor will it cause condensation on the lens surface due to temperature differences. In addition, the first through hole 1111 is set independently alongside the mounting hole, which also facilitates the independent sealing of the heat dissipation path inside the electronic device, thereby improving the sealing reliability of the electronic device.

[0045] In another alternative embodiment, as shown in Figures 7 and 8, the orthographic projection outline of the decorative element 120 lies within the orthographic projection outline of the fan 400 along the thickness direction of the housing 110. This can be understood as the orthographic projection outline of the decorative element 120 coinciding with the orthographic projection outline of the fan 400; or, the orthographic projection outline of the decorative element 120 being smaller than the orthographic projection outline of the fan 400. In this case, the decorative element 120 is located directly above the fan 400, therefore the decorative element 120 is a decorative element 120 for the fan 400. Both the first air inlet channel 101 and the second air inlet channel 102 are formed on the decorative element 120.

[0046] Specifically, the decorative element 120 has a first surface 120a facing away from the fan 400 and a first side surface 120b extending circumferentially along the first surface 120a. One end of the first air intake channel 101 facing away from the air inlet 401 can penetrate the first surface 120a, and one end of the second air intake channel 102 facing away from the air inlet 401 can penetrate the first side surface 120b. At this time, the end of the first air intake channel 101 connected to the external environment penetrates the top surface of the decorative element 120, and the end of the second air intake channel 102 connected to the external environment penetrates the side surface of the decorative element 120.

[0047] In this design, the heat dissipation and air intake are integrated into a single decorative component 120, eliminating the need for additional complex air intake holes on the rear cover 111. This reduces the processing steps and structural complexity of the housing 110, and decreases the number of components in the entire unit. Simultaneously, both air intake channels are formed on the decorative component 120. During assembly, simply snapping the decorative component 120 together ensures precise alignment of the first air intake channel 101 and the second air intake channel 102 with the lower fan 400, avoiding misalignment risks and eliminating airflow misalignment and leakage problems caused by assembly tolerances between the housing 110 and the decorative component 120. This ensures airflow sealing and heat dissipation efficiency. Furthermore, all air intake channels are concentrated in the decorative component 120 area, leaving the back of the housing 110 intact and hole-free, resulting in a cleaner and more upscale appearance. At the same time, the arrangement, size, and shape of the air intake channels can be freely designed on the decorative component 120, unrestricted by the structure of the housing 110, facilitating differentiated appearance designs and further enhancing the overall aesthetics. In addition, it can further improve the sealing performance. The air intake channels are all opened on the decorative part 120. Only the contact surface between the decorative part 120 and the housing 110 needs to be sealed. The sealing path is short and the sealing difficulty is low, which effectively prevents dust from entering from the assembly gap.

[0048] In the above scheme, the first air inlet channel 101 can extend from the top surface of the decorative element 120 to the bottom surface of the decorative element 120. The second air inlet channel 102 can be a winding maze channel, such as the first hole segment 1021 and the second hole segment 1022 mentioned above.

[0049] In another alternative embodiment, as shown in FIG8, the decorative element 120 may include a cover plate 124 and an annular side plate 125. The annular side plate 125 may extend circumferentially along the cover plate 124. The cover plate 124, the annular side plate 125, and a portion of the rear cover 111 form a guiding cavity 710. The area of ​​the rear cover 111 used to form the guiding cavity 710 is provided with a second through hole 1112 communicating with the guiding cavity 710. The second through hole 1112 may be disposed opposite to the air inlet 401.

[0050] The first surface 120a can be located on the side of the cover plate 124 away from the fan 400, and the first side surface 120b can be located on the outer peripheral surface of the annular side plate 125. The first air inlet channel 101 can be formed on the cover plate 124. The second air inlet channel 102 can be formed on the annular side plate 125, and both the first air inlet channel 101 and the second air inlet channel 102 can be connected to the guide cavity 710.

[0051] In this design, the through cavity 710 formed by the cover plate 124, the annular side plate 125 and the rear cover 111 is equivalent to a pre-stored air chamber. Outside air first enters the through cavity 710 for buffering and pressure stabilization, and then flows to the fan 400 through the second through hole 1112. This design effectively reduces the turbulence generated by the airflow directly impacting the fan 400, reduces wind resistance, and thus reduces operating noise.

[0052] At this time, the decorative part 120 not only serves the function of appearance decoration, but also integrates the air duct structure. There is no need to add an additional independent air guide cover or air duct component. The circumferential extension structure of the decorative part 120 forms the guide cavity 710, realizing the integration of function and structure, making the internal layout of the whole machine more compact, which is conducive to the miniaturization design of the product.

[0053] In some optional embodiments, as shown in FIG10, the decorative component 120 may include a first decorative cover 126 and a second decorative cover 127 that are separately disposed, and the first decorative cover 126 and the second decorative cover 127 may be disposed side by side on the rear cover 111. The camera module 800 may be located directly below the first decorative cover 126, in which case the first decorative cover 126 is the camera decorative cover. The camera module 800 and the fan 400 are disposed side by side, and the fan 400 is disposed opposite to both the first decorative cover 126 and the second decorative cover 127. Here, the second decorative cover 127 may also be used to decorate the fan 400, that is, to be the fan 400 decorative cover, and of course, it may also be a decorative cover for other components, which is not limited herein. The first air inlet channel 101 may be formed on the first decorative cover 126, and the second air inlet channel 102 may be formed on the second decorative cover 127.

[0054] In this design, the first decorative cover 126 and the second decorative cover 127 are separate and side-by-side, allowing for independent installation and removal. When either the camera module 800 or the fan 400 malfunctions, only the corresponding decorative cover needs to be removed for repair, eliminating the need for complete disassembly and significantly improving the convenience of future maintenance. The separate decorative cover design allows for differentiated appearance treatments for the camera area and the fan 400 area, such as different materials, colors, and textures, enhancing the product's visual hierarchy and design appeal. Different decorative covers correspond one-to-one with different components, resulting in a more visually organized appearance and improving the overall refinement and recognizability of the device.

[0055] In one embodiment, the first air intake channel 101 can be formed on the side wall of the first decorative cover 126, and the second air intake channel 102 can be formed on the side wall of the second decorative cover 127. In this case, both the first decorative cover 126 and the second decorative cover 127 adopt a side air intake structure. Of course, in another embodiment, both the first decorative cover 126 and the second decorative cover 127 can adopt a front air intake structure. Alternatively, in some other embodiments, one of the first decorative cover 126 and the second decorative cover 127 is a front air intake, and the other is a side air intake.

[0056] In an optional embodiment, the electronic device may further include a first dust filter 500 and a second dust filter 600. The first dust filter 500 may be located at the end of the first air intake channel 101 away from the fan 400. The second dust filter 600 may be located at the end of the second air intake channel 102 away from the fan 400. In this solution, independent dust filters are respectively provided at the air intake ends of the first air intake channel 101 and the second air intake channel 102, forming a dual-channel independent dust barrier. This effectively blocks external dust, hair, particles, and other impurities from entering the interior of the electronic device through the air intake channels, preventing dust from adhering to the fan 400 blades and internal circuits, thereby improving the dustproof performance of the electronic device. In addition, the dust filters impurities, preventing dust accumulation and blockage of the air intake channels, ensuring that the first air intake channel 101 and the second air intake channel 102 maintain the maximum effective air intake area for a long time, maintaining a stable air intake volume, preventing dust from covering the fan 400 or heat dissipation components, which would lead to a decrease in heat dissipation efficiency, ensuring long-term stable operation of the device, and avoiding overheating and frequency reduction caused by dust accumulation.

[0057] Furthermore, the first dustproof mesh 500 and the second dustproof mesh 600 are respectively embedded in the first air intake channel 101 and the second air intake channel 102. In this case, the dustproof mesh is set on the outer casing 100 as part of the air intake structure, thus not compromising the overall integrity of the outer casing 100 and avoiding the abruptness caused by exposed through-hole structures, maintaining a simple and sophisticated appearance. In addition, the dustproof mesh can be made of a material with the same color scheme or similar texture as the outer casing 100, visually blending with it without being obtrusive. Therefore, it ensures dustproof performance while presenting delicate texture details, enhancing the aesthetic appeal of the electronic device.

[0058] In some embodiments, the electronic device may further include a heat sink 300, which may be disposed within the housing 100 and located between the exhaust port 402 and the air outlet duct 103. In this case, the heat from the main heat sources, such as the central processing unit and the camera chip, is concentrated and conducted to the heat sink 300, and then carried away by the airflow. In this solution, the heat sink 300 is located between the air outlet duct 103 and the exhaust port 402, and is therefore on the main airflow path driven by the fan 400. The high-speed airflow generated by the fan 400 is forced to flow across the surface of the heat sink 300, quickly carrying away the internal heat absorbed by the heat sink 300, achieving forced convection cooling and significantly improving the overall heat dissipation capacity of the device.

[0059] Optionally, the heat sink 300 can be a heat dissipation structure such as heat sink fins or a heat dissipation plate.

[0060] In one optional embodiment, the heat sink 300 has a heat dissipation channel 301, and the exhaust channel 103 can be connected to the exhaust port 402 through the heat dissipation channel 301. In this solution, the heat sink 300 is constructed with a heat dissipation channel 301, which can increase the contact area between the airflow and the heat sink 300, thereby effectively improving the overall heat dissipation capacity. In addition, the air inlet channel, air inlet 401, heat dissipation channel 301, exhaust port 402, and exhaust channel 103 form a unique and closed heat dissipation air duct. The heat sink 300 itself acts as the air duct wall, filling the gaps in the internal structure, making it difficult for airflow to enter the space where other components are installed in the internal cavity, thus helping to further improve the sealing performance of the electronic device.

[0061] Optionally, the heat sink 300 includes heat dissipation fins and a heat spreader, which together form the aforementioned heat dissipation channel 301. Of course, the heat dissipation channel 301 can also be formed by other heat dissipation structures, which is not limited herein.

[0062] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices (such as smartwatches), video game consoles, etc. This application does not limit the specific types of electronic devices.
