Description

Technical Field

[0001] The present application relates to the technical field of server heat dissipation, and in particular to a windshield assembly. Background Art

[0002] In the server's cooling system, foam or Mylar sheets are typically used to seal the server's internal wiring channels and gaps to prevent airflow turbulence or backflow. Because foam or Mylar sheets are easy to shape, they are considered effective sealing materials in the prior art. They are primarily used to isolate cold and hot air, ensuring directional airflow and improving the server's overall heat dissipation efficiency.

[0003] However, the existing sealing methods of foam and Mylar sheets have significant limitations, especially in high-performance servers. Due to the continuous increase in the power consumption of the central processing unit (CPU) of such servers, the internal temperature of the server is high and the requirements for the cooling system are more stringent. Specifically, the foam or Mylar sheet mainly relies on the adhesive backing to be pasted on the inner wall of the server chassis or other fixed positions. This pasting method is prone to failure in high-temperature environments. The foam or Mylar sheet may fall off under the action of the airflow generated by the fan and be sucked into the fan, causing hardware failure and even causing the server to shut down and unable to operate normally, seriously affecting the operating stability of the server; in addition, since the internal wiring of the server is relatively complex, the twitching and pulling of the cables can easily damage the adhesion of the foam or Mylar sheet, further exacerbating the risk of material falling off and increasing the maintenance cost and time of the server.

[0004] Therefore, the existing sealing methods of foam or Mylar sheets face the problems of low reliability, poor safety and inconvenient maintenance during actual use, especially in high-power server environments. This not only seriously affects the heat dissipation performance of the server, but also poses a threat to the overall operating stability and service life of the server. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] An embodiment of the present application provides a windshield assembly, and the device is described in detail in combination with the structure and working principle of the windshield assembly (the technical terms involved must be explained).

[0033] like Figures 1 to 6 As shown, the windshield assembly is used to be installed in the wiring channel and / or gap of the server chassis 1 to prevent wind turbulence and / or backflow. The windshield assembly includes a support frame 10 and a windshield portion 20, wherein the support frame 10 is used to be connected to the server chassis 1; the windshield portion 20 is connected to the support frame 10, and the windshield portion 20 has a windshield brush 21, which is used to block the wiring channel and / or gap.

[0034] The present application forms an effective wind-blocking barrier by setting a wind-blocking brush 21, which effectively blocks the wiring channels and / or gaps, avoids wind turbulence or backflow, makes the wind flow inside the server more orderly, and effectively improves the heat dissipation efficiency. The application scenarios are mainly concentrated on the internal air duct management of the server, especially in high-power servers. By effectively guiding and controlling the wind flow, the normal operation and long-term stability of the server are guaranteed, and the service life of the server can also be ensured.

[0035] It should be noted that in the present application, the windshield 20 is detachably connected to the support frame 10. This ensures that the windshield 20 and the support frame 10 are easy to install and remove. If the windshield brush 21 of the windshield 20 needs to be replaced later, it can be directly replaced, ensuring the installation stability of the windshield 20 and improving the convenience of internal maintenance of the server.

[0036] It should be noted that, in the present application, the windshield 20 is snap-fitted with the support frame 10. In this way, by setting the windshield 20 and the support frame 10 in a snap-fitted structural form, the installation and removal convenience between the windshield 20 and the support frame 10 is ensured.

[0037] It should be noted that, in the present application, the windshield 20 is magnetically coupled with the support frame 10. In this way, by setting the windshield 20 and the support frame 10 in a magnetically coupled structural form, the installation and removal convenience between the windshield 20 and the support frame 10 is ensured.

[0038] like Figure 1 、 Figure 2 、 Figures 4 to 6 As shown, the windshield 20 includes a fixed structure 22 and a windshield brush 21. The fixed structure 22 is connected to the support frame 10 and has a guide slot 221. The windshield brush 21 includes a brush base 211 and a brush body 212. At least a portion of the brush base 211 is located within the guide slot 221. The brush body 212 is connected to the brush base 211 and is located outside the guide slot 221 to block the wiring channel and / or gap. In this way, by configuring the windshield 20 to include the fixed structure 22 and the windshield brush 21, the fixed structure 22 can ensure the installation stability of the windshield 20. In addition, by configuring the windshield brush 21 to include the brush base 211 and the brush body 212, the brush base 211 can ensure the reliability of the connection with the guide slot 221 of the fixed structure 22, and the arrangement of the brush body 212 can ensure the reliability of the blocking of the wiring channel and / or gap.

[0039] It should be noted that in this application, the brush body 212 of the windshield brush 21 is hard, linearly arranged, and tightly packed to enhance windshield performance and maintain a good straightness. The principle behind this design is that by selecting a hard plastic material, the brush body 212 (plastic bristles) of the windshield brush 21 maintains its shape and resists deformation even after prolonged use and in high-temperature environments, thereby providing a continuously stable windshield effect. Furthermore, the brush body 212 of the windshield brush 21 can effectively block turbulence, reduce wind resistance, and improve the directionality of airflow during server operation, thereby optimizing heat dissipation performance. This is particularly true near high heat sources within the server, such as around the CPU radiator. The precise positioning of the brush body 212 of the windshield brush 21 minimizes airflow waste and improves cooling efficiency.

[0040] It should be noted that in the present application, the brush base 211 and the guide slot 221 are interference fit. In this way, the connection reliability between the brush base 211 and the guide slot 221 is ensured, and the stable installation of the windshield brush 21 is ensured. The principle of this design is to ensure the stability of the windshield brush 21 inside the server through the precise fit between the brush base 211 and the guide slot 221, using friction and the tightness of the structural design, so that it is not easy to displace or fall off even under the impact of high-speed airflow. The implementation effect is to improve the stability of the windshield brush 21, avoid airflow short circuit or blockage caused by loose installation, and ensure the unobstructed flow of the air duct inside the server. The application scenario is in areas inside the server that require high-precision air duct control, such as the gap between the hard disk bracket and the radiator. The interference fit (transition fit) installation of the windshield brush 21 can effectively prevent dust and other foreign matter from entering, while ensuring the directional flow of airflow.

[0041] Furthermore, the brush base 211 slides along the length of the support frame 10 via the guide slot 221, thereby positioning and securing the windshield brush 21. This design utilizes the guiding action between the guide slot 221 and the brush base 211 to ensure accurate alignment of the windshield brush 21 during installation. Furthermore, the sliding installation method allows for rapid positioning and securing of the brush. This improves the installation accuracy and speed of the windshield 20, avoiding the potential installation deviation and structural instability associated with traditional fixing methods. The application scenario is the rapid construction and adjustment of the internal air duct of the server. Through the sliding cooperation between the guide groove 221 and the brush base 211, the positioning and fixation of the brush structure can be quickly completed. Especially when the server is deployed and expanded on a large scale, this quick installation method can significantly improve work efficiency and shorten the time to go online. The above-mentioned sliding method requires the use of external force to slide the brush base 211 into the guide groove 221. When the brush base 211 slides into the guide groove 221, the two are interference fit, and no relative movement occurs, thereby ensuring the installation stability of the windshield brush 21.

[0042] like Figures 2 to 5 As shown, the support frame 10 has a first clamping structure; the fixed structure 22 includes a fixed plate body 222 and two guide plates 223 arranged in pairs. A second clamping structure for clamping and cooperating with the first clamping structure is provided on the first surface of the fixed plate body 222. The two guide plates 223 are spaced apart on the second surface of the fixed plate body 222, forming a guide slot 221 between the two guide plates 223. The first and second surfaces are arranged in a direction away from each other. Thus, by providing the second clamping structure on the first surface of the fixed plate body 222 and the two guide plates 223 on the second surface of the fixed plate body 222, and forming the guide slot 221 between the two guide plates 223, the fixed structure 22 and the windshield brush 21, as well as the fixed structure 22 and the support frame 10, do not interfere with each other.

[0043] like Figures 2 to 5As shown, the first clamping structure is a gourd hole 11 provided on the support frame 10; the second clamping structure is a limiting protrusion 2221 protruding from the first surface, and the limiting protrusion 2221 has a head and a tail, the tail is connected to the first surface, and the head is connected to the tail and faces away from the first surface; wherein, the diameter D1 of the head, the diameter D2 of the tail, the large hole diameter D3 of the gourd hole 11, and the small hole diameter D4 of the gourd hole 11 satisfy the following: D2<D4<D1<D3. In this way, the reliability of the matching between the limiting protrusion 2221 and the gourd hole 11 is ensured, thereby ensuring that the head of the limiting protrusion 2221 passes through the large hole of the gourd hole 11 and then slides toward the small hole of the gourd hole 11, so that the tail of the limiting protrusion is limited at the small hole of the gourd hole 11, thereby realizing the constraint of the freedom of the fixed structure 22 in the front, back, left and right directions. Specifically, the front, back, left and right directions are based on the direction of the front window and rear window of the server chassis 1, with reference to FIG. Figure 2 The arrow B in FIG. 1 represents the front-back direction, and the arrow C represents the left-right direction.

[0044] like Figures 2 to 5 As shown, there are at least two first engaging structures, spaced apart along the extending direction of the guide slot 221. The number of second engaging structures matches and corresponds to the number of first engaging structures. Thus, by providing at least two first engaging structures and ensuring the same number of second engaging structures as first engaging structures, at least two limiting contact points are ensured between the two, thereby ensuring the secure installation of the fixing structure 22.

[0045] Furthermore, if Figures 2 to 5 As shown, there are two first clamping structures and two second clamping structures.

[0046] like Figures 2 to 5 As shown, the support frame 10 further has a third clamping structure; a fourth clamping structure for clamping and cooperating with the third clamping structure is further provided on the first surface of the fixing plate 222 .

[0047] like Figures 2 to 5 As shown, the fourth snap-fit ​​structure is an elastic snap-fit ​​2222 protruding from the first surface; the third snap-fit ​​structure is a limit slot 12 provided on the support frame 10, and the snap-fit ​​end of the elastic snap-fit ​​2222 can be snapped into the limit slot 12. In this way, by setting the elastic snap-fit ​​2222 to be pressed in the left-right direction, the elastic snap-fit ​​2222 can play a role in constraining the freedom of the fixed structure 22 in the up-down direction after being snapped into the limit slot 12. Figure 2 The arrow D in the figure indicates the up and down directions.

[0048] It should be noted that, in the present application, the first clip-on structure and the second clip-on structure are engaged in conjunction with each other, and the third clip-on structure and the fourth clip-on structure are engaged in conjunction with each other, so as to realize the tool-free installation and disassembly of the windshield 20. The principle of this design is to utilize the deformation ability of the elastic clip 2222 and the special geometric shape of the limiting protrusion 2221 to form a mechanical lock with the limiting slot 12 and the gourd hole 11 on the support frame 10, so that the installation and disassembly of the windshield 20 can be completed without additional tools. The implementation effect is to greatly simplify the maintenance and upgrade process of the internal components of the server, improve the working efficiency and reduce the maintenance cost. The application scenario is that during the batch production and maintenance of the server, through this tool-free installation design, the installation and disassembly of the brush structure can be completed quickly, especially in on-site maintenance or emergency troubleshooting, there is no need to look for tools, and it can be handled quickly, thereby improving the ability to deal with emergencies.

[0049] like Figure 3 As shown, the support frame 10 includes a first supporting structure 13 and a second supporting structure 14, wherein the first supporting structure 13 and the second supporting structure 14 are connected, and the first supporting structure 13 includes a first horizontal plate segment 131 and a vertical plate segment 132, the first horizontal plate segment 131 is used to connect with the server chassis 1, the vertical plate segment 132 is perpendicular to the first horizontal plate segment 131, and the vertical plate segment 132 is provided with a gourd hole 11 and a limit card slot 12, the two gourd holes 11 are located below the limit card slot 12, and the limit The positioning slot 12 is biased towards a side away from the second supporting structure 14; the second supporting structure 14 includes a second horizontal plate segment 141 and an inclined plate segment 142, wherein the second horizontal plate segment 141 is used to connect to the server chassis 1, and the inclined plate segment 142 is arranged at an angle to the second horizontal plate segment 141, and the angle between the two is an obtuse angle, and the first horizontal plate segment 131 and the second horizontal plate segment 141 are in opposite directions and have a phase difference of 180°, thereby ensuring the connection reliability between the support frame 10 and the server chassis 1.

[0050] It should be noted that in the embodiment not shown in the figure of the present application, the windshield 20 of the present application is a modular structure, which is connected to the server chassis 1 in conjunction with the support frame 10. By increasing the height of the support frame 10 or the length of the guide slot 221 of the fixed structure 22 of the windshield 20, multiple windshield brushes 21 can be spliced. The windshield brush 21 of the present application belongs to a single brush unit. By splicing multiple brush units (i.e., windshield brushes 21), it can adapt to the blocking requirements of different heights or lengths. The principle of this design is based on the modular design concept. By adjusting the height of the support frame 10 and the length of the guide slot 221, and splicing multiple identical or different brush units (i.e., windshield brushes 21), it can adapt to the blocking requirements of air ducts of different sizes inside the server. The implementation effect is to improve the versatility and adaptability of the windshield component, so that the windshield component provided by the present application can cover a wider range of server models and configurations, reducing customization costs. The application scenario is in the server production line. Faced with a variety of server models of different sizes and layouts, the modularly designed windshield components can be flexibly adjusted according to specific needs to achieve rapid adaptation and efficient production.

[0051] It should be noted that, in the present application, the modular design allows the windshield 20 to be quickly installed and disassembled without the use of tools, simplifying the maintenance process. The principle of this design is that through standardized interfaces and interchangeable designs, the installation and disassembly of the windshield 20 no longer rely on specific tools, but can be easily completed through manual operation. The implementation effect is to improve the flexibility and response speed of server maintenance. Especially in a high-density data center environment, this tool-free installation design can significantly reduce maintenance time and improve server availability and operation and maintenance efficiency. The application scenario is that during regular maintenance and emergency repairs in the data center, maintenance personnel can quickly complete the inspection, cleaning or replacement of the windshield 20 without carrying tools, which reduces the difficulty of maintenance and improves work efficiency.

[0052] As described above, the assembly process of the windshield assembly provided by the present application is given below. The support frame 10 is fixed to the wiring channel and / or gap at the bottom of the server chassis 1 where wiring is required by screws or rivets, and then the brush base 211 of the windshield brush 21 is pressed and slid into the guide groove 221 along the guide groove 221 of the fixing structure 22. The guide groove 221 and the brush base 211 are in an interference fit (transition fit) state, and the brush base 211 can be fixed in the guide groove 221. At this time, the windshield brush 21 and the fixing structure 22 form a whole. Finally, the fixing structure 22 is clamped onto the support frame 10. First, the limiting protrusion 2221 on the back of the fixing structure 22 is naturally placed into the large hole of the gourd hole 11 of the support frame 10, and then the fixing structure 22 is pushed toward the small hole direction of the gourd hole 11. At this time, the head (mushroom head) of the limiting protrusion 2221 can clamp the small hole, limiting the front and rear movement of the fixing structure 22 The fixing structure 22 is free to move in four directions, and the elastic buckle 2222 on the upper back of the fixing structure 22 is deformed and snapped into the limit slot 12 on the support frame 10, limiting the upper and lower degrees of freedom of the fixing structure 22, and the fixing structure 22 is completely fixed on the support frame 10; when it is necessary to clean and replace the windshield brush 21, the elastic buckle 2222 of the fixing structure 22 is pressed to unlock it in the limit slot 12, and the fixing structure 22 is lifted up at the same time, and the limit protrusion 2221 is unlocked from the gourd hole 11, and the fixing structure 22 together with the windshield brush 21 is removed from the support frame 10. Pull the plastic bristles of the windshield brush 21 and gently pull it in the opposite direction of the guide slot 221, so that the brush base 211 can slide out of the guide slot 221, and the windshield brush 21 can be cleaned, maintained or replaced with a new one. The whole process is tool-free and simple to operate, suitable for mass production operations, and has good maintainability.

[0053] In some exemplary embodiments, the windshield 20 includes a brush base 211, at least one row of plastic bristles (the brush body 212 is shown as multiple rows in the figure for illustrative purposes), a fixing structure 22, and a support frame 10. The brush base 211 is designed as an elongated strip, onto which at least one row of brush bodies 212 (i.e., plastic bristles) are hot-sealably bonded. The plastic bristles are hard, linearly arranged, and tightly packed, designed to improve windshield performance and maintain good straightness. The second surface (front) of the fixing structure 22 is designed with at least one guide groove 221 to guide the installation direction of the brush base 211 and ensure its stable guidance in the fixed position. The first surface (back) of the fixing structure 22 is designed with at least one elastic clip 2222 and at least one limiting protrusion 2221 to facilitate tool-free installation and removal from the support frame 10. At least one limiting slot 12 and at least one gourd hole 11 are designed on the vertical surface of the support frame 10, wherein the elastic buckle 2222 cooperates with the limiting slot 12, and the limiting protrusion 2221 cooperates with the gourd hole 11 to achieve stable installation and convenient disassembly of the wind shield 20.

[0054] In some exemplary embodiments, reinforcing ribs are designed at both ends of the brush base 211 to increase the structural strength of the brush base 211 and ensure that the plastic bristles are not easily deformed under wind pressure. The guide groove 221 of the fixed structure 22 is designed to be adjustable in width to ensure a good fit with brush bases 211 of different thicknesses. The elastic buckle 2222 is designed to be compressible, so that it can be pressed into the limiting slot 12 during installation to achieve quick installation. The limiting protrusion 2221 is designed to have a head with a certain elasticity. When inserted into the gourd hole 11, the head deforms to tighten the connection and prevent loosening. The limiting slot 12 and gourd hole 11 of the support frame 10 are designed with standard sizes to ensure compatibility with the fixed structure 22. At the same time, the multiple limiting slots 12 and gourd holes 11 on the facade are designed to allow multiple groups of brush units to be installed on the same bracket.

[0055] In some exemplary embodiments, the support frame 10 is fixed to the frame of the server chassis 1. By raising the support frame 10 or lengthening the fixing structure 22, multiple brush units can be spliced ​​and installed to meet the blocking requirements of different heights or lengths. The splicing of multiple brush units not only simplifies the maintenance process, but also improves the operating efficiency, especially in batch production operations, showing good operability and maintainability. In addition, the brush base 211 slides along the length direction of the support frame 10 through the guide groove 221 to achieve the positioning and fixation of the brush body 212, ensuring the smooth guidance of the airflow, avoiding airflow turbulence or backflow, and enhancing the stability and safety of the server system.

[0056] In some exemplary embodiments, the rigid plastic bristles can be made of materials such as polycarbonate (PC) and polybutylene terephthalate (PBT). The linear and dense arrangement can be achieved by designing the diameter of the plastic bristles and the spacing between adjacent bristles. For example, the diameter of the plastic bristles can range from 0.1 mm to 1.5 mm, and the spacing between adjacent bristles can range from 0.5 mm to 3 mm, to achieve optimal windshielding and straightening effects. The transitional fit between the brush base 211 and the fixed structure 22 can be controlled by the material of the brush base 211 (e.g., nylon, polypropylene, etc.) and the width of the guide slot 221 of the fixed structure 22, ensuring that the windshield 20 neither loosens nor becomes stuck during sliding installation.

[0057] The windshield portion 20 of the windshield assembly of the present application, through a modular design, allows for quick installation and removal without the use of tools. Specifically, the modular design allows users to splice multiple brush units according to actual needs by increasing the height of the support frame 10 or the length of the fixed structure 22. For example, when the height of the server chassis 1 is 2 meters, two 1-meter-long fixed structures 22 can be spliced ​​together; when the gap length of the server chassis 1 is 1.5 meters, two 0.75-meter-long brush units can be spliced ​​together to effectively block the airflow inside the server, meeting the diverse needs of different application scenarios.

[0058] The windshield assembly of this application, through the above design, demonstrates extremely high adaptability and scalability. It not only significantly improves the windshield effect inside the server, avoids airflow turbulence or backflow, and enhances the stability and security of the server system, but also greatly simplifies the maintenance process, improves work efficiency, and is suitable for batch production operations, demonstrating good operability and maintainability. Compared with traditional foam or Mylar sheet sealing methods, the windshield assembly avoids the problem of falling off due to high temperature or cable twitching, demonstrating its significant advantages in structural reliability and maintainability.

[0059] The technical solution of this application can bring the following beneficial effects:

[0060] 1. The windshield assembly is fixed by a mechanical structure, which is safe and reliable and will not fall off like foam, thus improving the reliability of the server system.

[0061] 2. The installation and removal of the windshield 20 is tool-free, which provides good operability and maintainability, thereby improving work efficiency;

[0062] 3. Thanks to the overall modular design, multiple brush units (windshield brushes 21) can be spliced ​​and installed by raising the bracket and lengthening the guide rail. The plastic bristles of the windshield brush 21 can have various lengths and specifications, which can be flexibly assembled and suitable for various application scenarios to meet diverse needs.
