[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] To address the problem of low heat dissipation efficiency of fan assemblies in related technologies, this application provides a housing and an electronic device having the same.

[0042] Example 1

[0043] like Figure 1 As shown, the housing includes a base 10 and a top cover 20. The top cover 20 covers the base 10, and a mounting cavity 30 is formed between the top cover 20 and the base 10. The mounting cavity 30 includes a fan assembly mounting area. The top cover 20 has an air inlet group 21, and the orthographic projection of the air inlet group 21 on the base 10 is located on the air inlet side of the fan assembly mounting area. The air inlet group 21 includes a plurality of air inlets 211 spaced apart along a first direction.

[0044] By applying the technical solution of this embodiment, an air intake group 21 is provided at the front end of the upper cover 20, above the air intake direction of the fan assembly. The air intake group 21 includes multiple air intake holes 211 spaced apart along a first direction, thereby optimizing the air intake path and improving air intake efficiency. This achieves a stable and efficient airflow introduction, thus solving the problem of low heat dissipation efficiency of the fan assembly in related technologies, ensuring insufficient heat dissipation of the fan assembly, and reducing fan noise. In this way, the above-mentioned arrangement of the air intake group 21 allows external air to flow more smoothly into the fan assembly mounting area within the mounting cavity 30, reducing turbulence and backflow phenomena before the airflow enters the fan, enhancing the fan's suction capacity, and improving the overall heat dissipation performance of the server system.

[0045] In this embodiment, each air inlet 211 includes a plurality of sub-air inlets 2111 spaced apart along a second direction, with at least two sub-air inlets 2111 staggered along a first direction; wherein the second direction is angled to the first direction. Thus, by providing sub-air inlets 2111 spaced apart along the second direction in each main air inlet 211, and with at least two sub-air inlets 2111 staggered along the first direction, the purpose of fine airflow distribution control is achieved, thereby enhancing airflow uniformity, reducing local eddy current generation, and solving the technical problems of low heat dissipation efficiency and local overheating caused by uneven airflow distribution.

[0046] Specifically, the air inlet 211 does not function as a single opening, but rather forms a micro-airflow distribution network through its internally staggered sub-air inlets 2111. When external air enters through the air inlet 211, it is further subdivided and redistributed by the sub-air inlets 2111, ensuring a more uniform airflow into the mounting cavity 30, covering more heat source areas, and improving overall heat dissipation efficiency. Simultaneously, the angle between the second direction and the first direction helps to disperse the direction of the incoming airflow, reducing mutual interference between airflows, preventing localized airflow concentration and the formation of eddies, further optimizing the heat dissipation path, and enhancing the stability and security of server operation.

[0047] Example 2

[0048] The difference between the casing in Embodiment 2 and Embodiment 1 is that the structure of the top cover 20 is different.

[0049] like Figure 2As shown, the upper cover 20 has a recessed portion 22 protruding towards the base 10. The recessed portion 22 includes a first flat plate 221 and a plurality of first inclined plates 222 sequentially connected circumferentially around the first flat plate 221. An air inlet group 21 is disposed on the first flat plate 221. In this way, by providing a recessed portion 22 on the surface of the upper cover 20 facing the base 10, which is composed of the first flat plate 221 and a plurality of first inclined plates 222 sequentially connected circumferentially around the first flat plate 221, and with the air inlet group 21 disposed on the first flat plate 221, the purpose of airflow pretreatment and guidance is achieved, thereby improving the airflow path, increasing air intake efficiency, and reducing wind noise.

[0050] In this embodiment, the recessed portion 22's aforementioned design makes the upper cover 20 not only a planar cover but also an airflow guiding platform. The first flat plate 221 serves as the support surface for the air inlet assembly 21, and its air inlets 211 can more effectively guide airflow into the fan assembly mounting area within the mounting cavity 30. The first inclined plate 222 further optimizes the airflow path, guiding the incoming airflow to transition more smoothly into the mounting cavity 30, avoiding turbulence and noise problems caused by airflow directly impacting the fan assembly. Thus, the above design ensures that the airflow receives optimal pre-guidance before entering the server interior, improving the fan's intake efficiency, enhancing heat dissipation performance, and reducing operating noise through the smooth transition of airflow.

[0051] Example 3

[0052] The difference between the casing in Example 3 and that in Example 1 is that the casing structure is different.

[0053] like Figures 3 to 12 As shown, the housing also includes an air guide plate 40. The air guide plate 40 is disposed within the mounting cavity 30 and opposite to the recess 22, forming an air guide region 41 around the recess 22; wherein, along the direction from the first flat plate 221 to at least one first inclined plate 222, the cross-section of the air guide region 41 gradually increases. In this way, by providing the air guide plate 40 opposite to the recess 22 of the upper cover 20 within the mounting cavity 30, a gradually expanding air guide region 41 is formed, wherein the cross-section of the air guide region 41 gradually increases along the direction from the first flat plate 221 to at least one first inclined plate 222 to form a Venturi effect, achieving the purpose of gradual airflow diffusion and guidance, thereby optimizing airflow distribution, improving fan suction efficiency, and reducing airflow resistance.

[0054] In this embodiment, the aforementioned gradually expanding air guide plate design utilizes the characteristics of airflow naturally decelerating and smoothly diffusing in a gradually expanding space. This effectively transforms the high-speed airflow entering through the air inlet group 21 of the recess 22 into low-speed airflow covering a wider area, ensuring that the airflow flows evenly and efficiently through the fan assembly mounting area. Based on the Venturi effect, as the airflow cross-section gradually expands, the airflow speed decreases, the pressure distribution becomes more uniform, reducing eddies and backflow phenomena caused by localized high-speed airflow. Simultaneously, it reduces the impact force of the airflow at the fan, reduces airflow resistance, and improves the fan's operating efficiency.

[0055] like Figure 7 , Figures 10 to 12 As shown, the air guide plate 40 includes a second inclined plate 42, a second flat plate 43, and a third inclined plate 44, which are bent sequentially. The second inclined plate 42 and the third inclined plate 44 are both located on the same side of the second flat plate 43 and extend towards the side opposite to the recess 22. The second flat plate 43 is arranged parallel to the first flat plate 221, the second inclined plate 42 is arranged corresponding to one of the first inclined plates 222, and the third inclined plate 44 is arranged corresponding to another of the first inclined plates 222. In this way, the various parts of the multi-segment bent air guide plate form a gradually changing airflow channel, achieving the purpose of precise airflow guidance and speed control, thereby realizing the technical effects of improving the uniformity of airflow distribution, reducing airflow resistance, and enhancing airflow stability.

[0056] In this embodiment, the multi-segment bent air guide plate 40 is designed to better match the recessed portion 22 of the upper cover 20, forming a gradually changing air guide area 41. The parallel arrangement of the second flat plate 43 and the first flat plate 221 ensures a smooth transition of airflow when entering the air guide area 41, avoiding sudden changes in airflow. The corresponding arrangement of the second inclined plate 42 and the first inclined plate 222 further guides the airflow and gradually adjusts its direction and speed, making it more in line with the fan's intake requirements and reducing resistance and noise caused by direct airflow impact on the fan. The corresponding arrangement of the third inclined plate 44 and another first inclined plate 222 further optimizes the airflow path, ensuring a uniform distribution of airflow when leaving the air guide area 41, avoiding local overspeed or underspeed, thereby improving the heat dissipation efficiency of the fan assembly and the overall operational stability. Thus, the finely designed air guide plate 40 not only improves airflow distribution but also reduces airflow resistance during the introduction process, enhancing the overall heat dissipation performance and operating efficiency of the electronic device.

[0057] It should be noted that the corresponding arrangement of the second inclined plate 42 and a first inclined plate 222 means that the two are arranged opposite each other along the height direction of the casing.

[0058] It should be noted that the corresponding arrangement of the third inclined plate 44 and the other first inclined plate 222 means that the two are arranged opposite each other along the height direction of the casing.

[0059] Optionally, the distance L between the first plate 221 and the second plate 43 is greater than or equal to 8 mm and less than or equal to 12 mm; and / or, the angle between the second inclined plate 42 and the second plate 43 is greater than or equal to 160° and less than or equal to 165°; and / or, the angle between the third inclined plate 44 and the second plate 43 is greater than or equal to 165° and less than or equal to 172°; and / or, the angle between the first inclined plate 222, which is opposite to the second inclined plate 42, and the first plate 221 is greater than or equal to 160° and less than or equal to 165°; and / or, the angle between the first inclined plate 222, which is opposite to the third inclined plate 44, and the first plate 221 is greater than or equal to 165° and less than or equal to 172°. In this way, by strictly setting the distance L between the air guide plate 40 and the recessed part 22 and the included angle between each inclined plate and the flat plate, the purpose of precise airflow control and minimum resistance design is achieved, thereby realizing the technical effects of maximizing airflow introduction efficiency, minimizing wind resistance loss and balancing airflow distribution.

[0060] In this embodiment, the distance L between the first plate 221 and the second plate 43 is 10 mm, the angle between the second inclined plate 42 and the second plate 43 is 165°, and the angle between the third inclined plate 44 and the second plate 43 is 170°. The angle between the first inclined plate 222, which is opposite to the second inclined plate 42, and the first plate 221 is 165°, and the angle between the first inclined plate 222, which is opposite to the third inclined plate 44, and the first plate 221 is 170°. Thus, the aforementioned distance L ensures that the airflow has sufficient space for initial diffusion and adjustment when entering the airflow guiding area 41, avoiding excessive compression or dispersion of the airflow and providing an optimal starting point for subsequent airflow guidance. The 165° angle between the second inclined plate 42 and the second flat plate 43, and the 170° angle between the third inclined plate 44 and the second flat plate 43, ensure a smooth transition and speed control of airflow within the air guiding area 41 formed between the air guide plate 40 and the recess 22. This reduces airflow turbulence, lowers wind resistance, and improves airflow introduction efficiency. Simultaneously, the 165° and 170° angles between the first inclined plate 222 and the first flat plate 221, which are opposite to the second and third inclined plates 42 and 44 respectively, further optimize the airflow path, ensuring uniform distribution and consistent direction of airflow when entering the fan assembly area within the mounting cavity 30. This improves heat dissipation efficiency and the overall operational stability of the system.

[0061] Optionally, the air guide plate 40 is provided with a connecting post 45, and the housing also includes fasteners that pass through the upper cover 20 and the connecting post 45 to connect the upper cover 20 and the air guide plate 40. The housing also includes a filter 60 disposed between the air inlet group 21 and the air guide plate 40; and / or, the housing also includes a buffer 70 disposed between the side of the air guide plate 40 and the base 10; and / or, the buffer 70 disposed between the side of the air guide plate 40 and the fan assembly 80. In this way, by setting a connecting post 45 on the air guide plate 40 and using fasteners to securely connect the top cover 20 and the air guide plate 40, and by setting a filter 60 between the air inlet group 21 and the air guide plate 40, and by setting a buffer 70 between the side of the air guide plate 40 and the base 10, or between the side of the air guide plate 40 and the fan assembly 80, the purpose of comprehensive protection and optimized operation is achieved, thereby improving system reliability, vibration reduction and noise reduction and extending component life.

[0062] like Figure 10 and Figure 11 As shown, a connecting post 45 is provided on the air guide plate 40. The housing also includes fasteners, which pass through the upper cover 20 and the connecting post 45 to connect the upper cover 20 and the air guide plate 40. The housing also includes a filter 60 and a buffer 70. The filter 60 is disposed between the air inlet group 21 and the air guide plate 40. Multiple buffers 70 are present; at least one buffer 70 is disposed between the side of the air guide plate 40 and the base 10, and at least another buffer 70 is disposed between the side of the air guide plate 40 and the fan assembly 80. Thus, the combined use of the connecting post 45 and the fasteners ensures reliable fixation between the air guide plate 40 and the upper cover 20, preventing component displacement or loosening due to vibration or thermal expansion and contraction during operation, ensuring the integrity of the airflow guiding structure, and improving the mechanical stability and airflow guiding accuracy of the entire housing.

[0063] In this embodiment, the filter 60 is disposed between the air inlet group 21 and the air guide plate 40, which can effectively block the intrusion of external dust and impurities, protect the internal electronic components from contamination, reduce the frequency of cleaning and maintenance, and extend the service life of the server. Whether the buffer 70 is placed between the side of the air guide plate 40 and the base 10, or between the side of the air guide plate 40 and the fan assembly 80, it can play a shock-absorbing role, reducing mechanical damage caused by direct collisions between components, while also buffering the direct impact of airflow on the fan assembly 80, reducing wind noise, and improving the quietness and comfort of the server during operation.

[0064] Optionally, the cushioning element 70 is foam.

[0065] Optionally, each air inlet 211 is a strip-shaped hole, which is inclined and the inclination angle α relative to the neutral surface S of the upper cover 20 is greater than or equal to 5° and less than or equal to 25°. In this way, by designing each air inlet 211 as a strip-shaped hole and making these strip-shaped holes inclined relative to the neutral surface S of the upper cover 20, with the inclination angle α set in the range of 5° to 25°, the purpose of directional airflow introduction and airflow guidance optimization is achieved, thereby improving the fan's air intake efficiency, reducing wind resistance, and enhancing airflow stability.

[0066] In this embodiment, the strip-shaped perforation provides a larger airflow area and better airflow guidance compared to circular or other shaped perforations. The tilt angle allows for pre-guiding of the incoming airflow in a specific direction, avoiding direct vertical impact, reducing airflow resistance, and preventing direct reflection of the airflow in the fan assembly's intake direction. This design ensures that the airflow is introduced into the mounting cavity 30 with lower resistance and greater stability, improving the fan assembly's intake efficiency and enhancing heat dissipation performance. Furthermore, the tilted strip-shaped perforation also provides dust prevention and noise reduction. By controlling the airflow introduction angle, it effectively reduces the direct entry of external dust, and the smooth airflow transition reduces noise during the airflow introduction process, providing the server with an optimized solution that combines high heat dissipation efficiency, low maintenance requirements, and a quiet operating environment. The tilted strip-shaped perforation design not only improves airflow introduction and distribution but also optimizes the noise performance of the server during operation, enhancing the overall performance of the electronic equipment and the user experience.

[0067] like Figure 9 , Figure 11 as well as Figure 12 As shown, the housing also includes a support plate 50. The support plate 50 is disposed between the air guide plate 40 and the upper cover 20. The support plate 50 has a supporting surface and a connecting surface arranged opposite to each other. The supporting surface contacts the upper cover 20 and is adapted to the shape of the recess 22, while the connecting surface connects to the air guide plate 40 and is adapted to the shape of its upper surface. The support plate 50 includes a bent section 51, which contacts the first flat plate 221, and the extension direction of the bent section 51 is parallel to the extension direction of the strip hole. This arrangement of the support plate 50 enhances the mechanical stability between the air guide plate 40 and the upper cover 20, preventing structural deformation that may occur during long-term operation or temperature changes, and ensuring the integrity and long-term reliability of the airflow guiding structure. The shape of the supporting surface is adapted to the recess 22, allowing it to fit tightly against the recess 22 of the upper cover 20, providing a stable support foundation for the airflow guiding area 41 and ensuring the accuracy of airflow guidance. The connecting surface is adapted to the shape of the upper surface of the air guide plate 40, which further enhances the structural stability of the air guide plate 40 and enables it to maintain the best air guiding performance under various operating conditions.

[0068] In this embodiment, the bending section 51 contacts the first flat plate 221, which not only increases the contact area between the support plate 50 and the recessed portion 22 and improves the overall stability of the structure, but also, since the extension direction of the bending section 51 is parallel to the extension direction of the strip hole, it can further refine the airflow guidance path, realize precise airflow control, avoid accidental deviation of airflow during the introduction process, reduce the generation of turbulence, and improve the intake efficiency and heat dissipation performance of the fan assembly.

[0069] This application also provides an electronic device (not shown) including the aforementioned housing.

[0070] Optionally, the electronic devices include, but are not limited to, electronic devices with fan assemblies, such as servers, switches, storage devices, and personal computers.
