[0043] 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.

[0044] like Figures 1 to 18 As shown, the present application provides an air scoop with an adjustable opening rate, comprising: an air scoop main body 1, on which an air guide hole 10 is provided; an adjusting baffle assembly 2, which is arranged on the air scoop main body 1 and located at the air guide hole 10; the adjusting baffle assembly 2 comprises a plurality of baffles 20, each of which is provided with a flow hole 200, and at least one of the size, position and number of the flow holes 200 on any two of the plurality of baffles 20 is different; wherein, any two of the plurality of baffles 20 can be stacked on each other or arranged separately to adjust the actual flow area of ​​the adjusting baffle assembly 2.

[0045] The air guide hood with adjustable opening rate of the present application adjusts the actual opening rate of the air guide hood by setting an adjustable baffle assembly 2 to change the relative positions between multiple baffles 20 to adapt to different heat dissipation requirements. It solves the problem in the related art that the air guide hood with fixed opening rate cannot be dynamically adjusted according to actual heat dissipation requirements, achieves the technical effect of reducing the cost increased by setting up a variety of different air guide hoods, avoids the need to set up separate air guide hoods for different heat-generating components, and improves heat dissipation efficiency and flexibility.

[0046] The application scenarios of the air guide cover with adjustable opening ratio in the present application include high-performance computing equipment such as servers and data centers. The configuration and power consumption of the internal components of these devices may change over time, and the power consumption of different heat-generating components is also different. Therefore, a flexible heat dissipation structure needs to be set up. The air guide cover with adjustable opening ratio in the present application can optimize the heat dissipation effect, provide a more efficient and economical solution for the thermal management of the server, and has broad application prospects.

[0047] Specifically, "at least one of the size, position and number of the flow holes 200 on any two baffles 20 among the multiple baffles 20 is different" may include the following situations: between any two baffles 20 among the multiple baffles 20, the size of the flow holes 200 on one baffle 20 is different from the size of the flow holes 200 on the other baffle 20; and / or, the position of the flow holes 200 on one baffle 20 is different from the position of the flow holes 200 on the other baffle 20; and / or, the number of the flow holes 200 on one baffle 20 is different from the number of the flow holes 200 on the other baffle 20.

[0048] The actual flow area of ​​the baffle assembly 2 is adjusted as follows: Figure 5 、 Figure 7 、 Figure 9 、 Figure 11 and Figure 12 The area indicated by the symbol "S" is the area of ​​the actual through hole formed by the multiple baffles 20 stacked on each other.

[0049] like Figure 4 and Figure 5As shown, any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22; wherein, the first baffle 21 is provided with a plurality of first flow holes 201 at intervals, and the second baffle 22 is provided with a plurality of second flow holes 202 at intervals, the multiple first flow holes 201 are provided with the multiple second flow holes 202 in a one-to-one correspondence, and the size of each first flow hole 201 is larger than the size of the corresponding second flow hole 202; when the first baffle 21 and the second baffle 22 are stacked on each other, a part of each first flow hole 201 is overlapped with the position of the corresponding second flow hole 202, and the projection of the hole cross section of each second flow hole 202 on a predetermined plane parallel to the air guide cover body 1 is located within the projection of the hole cross section of the corresponding first flow hole 201 on the predetermined plane parallel to the air guide cover body 1.

[0050] The air guide cover with adjustable opening rate of the present application realizes the adjustment of the actual flow area of ​​the baffle assembly 2 by respectively setting flow holes 200 of different sizes and positions on the first baffle 21 and the second baffle 22, and stacking different numbers of baffles 20, thereby realizing the adjustment of the actual opening rate of the air guide cover, which can accurately control the amount of airflow passing through and improve the flexibility and efficiency of heat dissipation.

[0051] like Figure 10 and Figure 11 As shown, any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22; wherein, the first baffle 21 is provided with a plurality of first flow holes 201 at intervals, and the second baffle 22 is provided with a plurality of second flow holes 202 at intervals, the multiple first flow holes 201 and the multiple second flow holes 202 are provided in a one-to-one correspondence, and the size of each first flow hole 201 is equal to the size of the corresponding second flow hole 202; when the first baffle 21 and the second baffle 22 are stacked on each other, a portion of each first flow hole 201 coincides with a portion of the corresponding second flow hole 202.

[0052] The air guide cover with adjustable opening rate of the present application realizes the adjustment of the actual flow area of ​​the baffle assembly 2 by respectively setting flow holes 200 at different positions on the first baffle 21 and the second baffle 22, and stacking different numbers of baffles 20, thereby realizing the adjustment of the actual opening rate of the air guide cover, which can accurately control the amount of airflow passing through and improve the flexibility and efficiency of heat dissipation.

[0053] like Figure 12 and Figure 13As shown, any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22; wherein, the first baffle 21 is provided with a plurality of first flow holes 201 at intervals, and the second baffle 22 is provided with a plurality of second flow holes 202 at intervals, the multiple first flow holes 201 are provided with the multiple second flow holes 202 in a one-to-one correspondence, and the size of each first flow hole 201 is larger than the size of the corresponding second flow hole 202; when the first baffle 21 and the second baffle 22 are stacked on each other, a portion of each first flow hole 201 is overlapped with a portion of the corresponding second flow hole 202, and a portion of the projection of the hole cross section of each second flow hole 202 on a predetermined plane parallel to the air guide cover body 1 is located within a portion of the projection of the hole cross section of the corresponding first flow hole 201 on the predetermined plane parallel to the air guide cover body 1.

[0054] The air guide cover with adjustable opening rate of the present application realizes the adjustment of the actual flow area of ​​the baffle assembly 2 by respectively setting flow holes 200 of different sizes and positions on the first baffle 21 and the second baffle 22, and stacking different numbers of baffles 20, thereby realizing the adjustment of the actual opening rate of the air guide cover, which can accurately control the amount of airflow passing through and improve the flexibility and efficiency of heat dissipation.

[0055] like Figures 6 to 9 As shown, any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22; wherein, the first baffle 21 is provided with a plurality of first flow holes 201 at intervals, and the second baffle 22 is provided with a plurality of second flow holes 202 at intervals, the number of the multiple first flow holes 201 is not equal to the number of the multiple second flow holes 202, and at least one of the multiple first flow holes 201 is provided in a one-to-one correspondence with at least one of the multiple second flow holes 202; when the first baffle 21 and the second baffle 22 are stacked on each other, at least part of each first flow hole 201 overlaps with at least part of the position of the corresponding second flow hole 202.

[0056] The air guide cover with adjustable opening rate of the present application realizes the adjustment of the actual flow area of ​​the baffle assembly 2 by respectively setting different numbers and positions of flow holes 200 on the first baffle 21 and the second baffle 22, and stacking different numbers of baffles 20, thereby realizing the adjustment of the actual opening rate of the air guide cover, which can accurately control the amount of airflow passing through and improve the flexibility and efficiency of heat dissipation.

[0057] It should be noted that “any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22” does not mean that the multiple baffles 20 only include the first baffle 21 and the second baffle 22, but that the specific number of the multiple baffles 20 can be any integer greater than one, and any two baffles 20 taken from these baffles 20 can be the first baffle 21 and the second baffle 22.

[0058] like Figure 4 and Figure 5 In the embodiment shown, the regulating baffle assembly 2 includes three baffles 20, any two of the three baffles 20 are the first baffle 21 and the second baffle 22, and the three baffles 20 are arranged in sequence from large to small in terms of opening rate in a direction away from the air guide hole 10, one layer at a time. In the process of stacking the three baffles 20 in sequence, the actual flow area of ​​the regulating baffle assembly 2 gradually decreases, and when all the three baffles 20 are stacked together, the actual flow area of ​​the regulating baffle assembly 2 is the smallest.

[0059] Optionally, the baffle 20 is made of thinner material, the first and foremost of which is significant cost savings. The use of thin materials reduces the consumption of raw materials, which directly reduces manufacturing costs. Especially in a mass production environment, this advantage will be magnified, having a positive impact on overall cost control. Secondly, the thin baffle 20 reduces weight, so multiple baffles 20 can be installed on the air duct without affecting the volume of the air duct, which helps to reduce the overall burden on the server. Especially in high-density deployment scenarios, reducing weight means reducing the need for physical support structures, further reducing server architecture costs, while also facilitating the installation and replacement of baffles and improving the operational efficiency of on-site engineers. Therefore, the thinner baffle 20 not only excels in cost control, weight reduction, heat dissipation optimization, and system flexibility, but also embodies the concept of modern server design that focuses on high efficiency, energy saving, intelligent management, and sustainable development.

[0060] Optionally, the baffle 20 may be a metal plate, a cardboard plate, or a plastic plate.

[0061] like Figures 14 and 15 As shown, any two baffles 20 among the multiple baffles 20 are respectively the first baffle 21 and the second baffle 22; wherein, the first baffle 21 is provided with a bonding portion 3, so as to be bonded to or separated from the second baffle 22 through the bonding portion 3; and / or, the first baffle 21 is provided with a magnetic portion 4, so as to be adsorbed or separated from the second baffle 22 through the magnetic portion 4; and / or, the first baffle 21 is provided with a first buckling portion, and the second baffle 22 is provided with a second buckling portion corresponding to the first buckling portion, and the first baffle 21 is buckled with or separated from the second baffle 22 through the first buckling portion and the second buckling portion.

[0062] The adjustable baffle assembly 2 of the air scoop with an adjustable aperture ratio of the present application utilizes adhesive bonding, magnetic attraction, or snap-fitting to quickly lock or unlock the relative position between the first baffle 21 and the second baffle 22, thereby facilitating rapid adjustment of the relative position between the first baffle 21 and the second baffle 22, thereby rapidly adjusting the aperture ratio of the air scoop. This improves the convenience and efficiency of adjusting the heat dissipation capacity of the air scoop with an adjustable aperture ratio, and reduces the maintenance cost of the server. In this case, the baffle 20 may be a metal plate, cardboard, or plastic plate.

[0063] In addition, the adjustable baffle assembly 2 of the air scoop with adjustable aperture ratio and the air scoop main body 1 can also be connected or separated by methods similar to the above-mentioned pasting, magnetic attraction or buckling.

[0064] exist Figure 14 In the illustrated embodiment, the air scoop with adjustable aperture ratio of the present application is provided with an adhesive portion 3 on the first baffle 21, so that the first baffle 21 can be easily attached to or separated from the second baffle 22, thereby enabling the first baffle 21 and the second baffle 22 to be switched between stacking or separation, which significantly improves the flexibility and efficiency of adjusting the aperture ratio of the air scoop. Compared to mechanical connection, the design of the adhesive portion 3 reduces the complexity of assembly and reduces the risk of wear caused by frequent switching of the relative positions of the first baffle 21 and the second baffle 22. At the same time, the ease of the adhesive operation allows users or maintenance personnel to quickly switch the relative positions of the first baffle 21 and the second baffle 22 without tools, greatly improving the response speed and ease of use of server heat dissipation management. Furthermore, the reversibility of the adhesive portion allows for reversible and lossless replacement of the relative positions of the first baffle 21 and the second baffle 22, further reducing operational costs and enhancing the maintainability and sustainability of the air duct with adjustable aperture ratio. This provides a more convenient, efficient, and economical solution for the server's cooling system, enabling dynamic adjustment of the aperture ratio based on different configurations and cooling requirements, ensuring optimal cooling performance under various load conditions. The adhesive portion 3 may be adhesive or double-sided tape, and is disposed around the edge of the first baffle 21. The baffle 20 may be a metal plate, cardboard, or plastic sheet.

[0065] exist Figure 15In the illustrated embodiment, the adjustable aperture ratio air scoop of the present application is provided with a magnetic attraction portion 4 on the first baffle 21, so that it can be easily attached to or separated from the second baffle 22 through magnetic attraction, thereby realizing the switching between the first baffle 21 and the second baffle 22 being stacked or separated, greatly improving the air scoop's operational flexibility and intelligent control capabilities. The use of the magnetic attraction portion eliminates the assembly difficulty and potential damage caused by mechanical connection, and realizes the tool-free and contactless rapid switching of the relative position between the first baffle 21 and the second baffle 22, significantly saving maintenance time and labor costs. More importantly, the provision of the magnetic attraction portion 4 allows the adjustable aperture ratio air scoop to dynamically adjust the aperture ratio. The magnetic attraction portion 4 can also be configured as an electromagnet to achieve the adsorption or separation between the first baffle 21 and the second baffle 22 by controlling the magnetic state of the magnetic attraction portion, so as to intelligently change the relative position between the first baffle 21 and the second baffle 22 according to the real-time heat dissipation requirements and server configuration, without the need for manual intervention and with a high degree of automation. Furthermore, the non-destructive nature of the magnetic attraction ensures the reusability of the baffle 20, reducing material loss due to frequent replacement. This enables efficient, flexible, and automated thermal management, significantly enhancing the server's adaptability and intelligent control capabilities in response to diverse hardware configurations and dynamic cooling requirements. Furthermore, the magnetic attraction portions 4 on different baffles 20 in the baffle assembly 2 can be staggered. In this case, the baffle 20 needs to be a metal plate that can be magnetically attracted.

[0066] In an embodiment not shown in the figures of the present application, the air guide cover with adjustable aperture ratio of the present application is provided with a first snap-fitting portion on the first baffle 21 and a corresponding second snap-fitting portion on the second baffle 22. Through the interaction between the first snap-fitting portion and the second snap-fitting portion, the first baffle 21 and the second baffle 22 can be quickly snapped together or separated, thereby realizing the switching of the first baffle 21 and the second baffle 22 between stacking or separating each other, effectively improving the operability and maintainability advantages of the air guide cover with adjustable aperture ratio, making the relative position replacement between the first baffle 21 and the second baffle 22 simple and quick, and the staff can realize the switching of the relative position between the first baffle 21 and the second baffle 22 without complicated tools, which significantly shortens the maintenance and configuration adjustment time and improves the thermal management efficiency of the server. Furthermore, this snap-fit ​​structure ensures the stability and positioning accuracy of the connection between the first baffle 21 and the second baffle 22, preventing relative displacement between the first baffle 21 and the second baffle 22 due to airflow impact or vibration during server operation. This enhances the safety and reliability of the air guide cover with adjustable aperture ratio, and also improves the stability and performance of the server's heat dissipation, providing a flexible and efficient solution for the diverse configuration and heat dissipation requirements of server hardware.
