For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] Reference below Figure 1-Figure 7 Described is an air guide structure 100 for electrical equipment according to an embodiment of the present invention. An air outlet 17 is provided on the side of the air guide cover 1 facing the card insertion structure, and the size of the air outlet 17 is adjusted by the wind shield 2. That is, when the types of smart network cards in the card insertion structure are different, the size of the air outlet 17 can be adjusted to meet the optimal heat dissipation and air guide requirements of different smart network cards.

[0032] like Figure 1-7 As shown, according to an embodiment of the present invention, an air guide structure 100 for an electrical device includes a card insertion structure and an air guide structure, and the air guide structure includes: an air guide cover 1 and a wind shield 2.

[0033] Among them, the wind guide cover 1 forms an air guide channel, and the air guide channel forms an air outlet 17, which is used to discharge air toward the card insertion structure; the wind shield 2 can be movably installed at the air outlet 17, and the wind shield 2 is used to adjust the opening size of the air outlet 17.

[0034] In practice, the airflow enters the air guide cover 1, flows in the air guide channel, and flows into the plug-in card structure through the air outlet 17 of the air guide channel. The plug-in card structure can be a PCIe module bracket 3 (high-speed serial computer expansion bus standard bracket). The smart network card can be plugged into the PCIe module bracket 3. The smart network card is regarded as a programmable network card. It can not only perform traditional network data transmission functions, but also accelerate network, storage and security functions, and perform tasks such as virtualization, load balancing and data path optimization. The smart network card is equipped with computing power, allowing it to offload all network functions, security functions and storage functions from the host server, thereby freeing up valuable processing power and enabling the server to focus on running critical applications and operating systems more efficiently.

[0035] Among them, the Smart NIC consumes a large amount of electricity and converts it into heat energy when performing network data transmission, accelerating network functions, and executing virtualization tasks. This high power consumption causes the Smart NIC to generate significant heat during operation, thus requiring heat dissipation for the Smart NIC. Specifically, the Smart NIC can be a single-width Smart NIC 31 or a dual-width Smart NIC 32. The dual-width Smart NIC 32 is generally larger and heavier than the single-width Smart NIC 31 and requires a larger heat dissipation system. Therefore, the single-width Smart NIC 31 and the dual-width Smart NIC 32 require different sizes of heat dissipation outlets 17.

[0036] Traditionally, different smart network cards correspond to different air guide covers 1, which is costly. Every time a different smart network card is set up, the air guide cover 1 needs to be replaced, which makes maintenance inconvenient and inefficient. However, an air guide cover 1 in the embodiment of the utility model can be suitable for smart network cards of different sizes by adjusting the wind shield 2. For example, a double-width smart network card 32 requires a larger air outlet 17 for heat dissipation to improve heat dissipation efficiency, while a single-width smart network card 31 requires a smaller air outlet 17 for heat dissipation, and the air volume is concentrated from the smaller air outlet 17 to the single-width smart network card 31, which can improve the heat dissipation efficiency of the single-width smart network card 31.

[0037] In practice, the wind shield 2 can be a wind shield plate, which is located at the air outlet 17 and movably installed at the air outlet 17. If the position and angle of the wind shield plate change, the blocking effect on the air outlet 17 can be different, thereby adjusting the size of the air outlet 17.

[0038] Therefore, the wind shield 2 of the embodiment of the utility model is set in an adjustable manner, so that the entire air guide structure is suitable for better heat dissipation of different smart network cards to improve the heat dissipation effect. At the same time, there is no need to set different air guide covers 1 for smart network cards with different structures, which saves costs.

[0039] In some embodiments, the wind shield 2 rotates relative to the wind guide cover 1 along the rotation axis to adjust the size of the air outlet 17 .

[0040] Among them, the wind shield 2 is rotated and connected to the wind guide cover 1, so that the angle of the wind shield 2 can be changed. The wind shield is a wind shield. When the wind shield rotates, the resistance to the airflow flowing out along the air outlet 17 changes, that is, the size of the air outlet 17 can be adjusted to meet different heat dissipation requirements, so that different smart network cards can obtain effective heat dissipation, and by setting the wind shield 2 to rotate relative to the wind guide cover 1 along the rotation axis, the adjustment efficiency of the wind shield 2 can be improved, and the different rotation angles will result in different blocking effects of the wind shield 2 on the airflow, which can produce a variety of heat dissipation effects of different degrees.

[0041] like Figure 5 As shown, when the single-width smart network card 31 is facing the bottom of the windshield, the airflow is mainly guided and concentrated to flow out from the bottom of the windshield 2 to improve the heat dissipation effect of the single-width smart network card 31. Figure 6 As shown, when the smart network card is a double-width smart network card 32, the air outlet 17 can be adjusted to the maximum through the wind shield to improve the heat dissipation effect of the larger double-width smart network card 32. Figure 5 and Figure 6 The thickness in the height direction is different, so the relative position with the air outlet 17 is different. By adjusting the opening size of the air outlet 17, different airflows can be directed to different smart network cards to meet different heat dissipation requirements.

[0042] In some embodiments, the wind guide cover 1 is provided with an arc-shaped guide portion 121 on one side of the rotation axis, and the wind shield 2 is adapted to be rotated along the rotation axis and guided along the arc-shaped guide portion 121 at the same time.

[0043] In practice, the arc-shaped guide portion 121 can be an arc-shaped guide groove, and the windshield has a rotating shaft 21 and a guide shaft 22, and the rotating shaft 21 and the guide shaft 22 are parallel. When the rotating shaft 21 rotates relative to the rotating axis, the guide shaft 22 guides along the arc-shaped guide groove, thereby maintaining the stability of the windshield rotation and adjusting the required position. In addition, the arc-shaped guide groove can also be used to limit the rotation of the windshield, so that the windshield rotates according to a predetermined path, thereby ensuring that the windshield can rotate according to the required size of the air outlet 17.

[0044] In addition, assuming that the rotation axis is the central axis of a circle, the distance between the rotation axis and the arc-shaped guide groove can basically be regarded as the radius of the circle. When the windshield is a rectangular windshield, the rotation axis 21 and the guide axis 22 can be spaced apart along the width direction of the rectangular windshield, so that when the rotation axis 21 of the windshield rotates along the rotation axis, the guide axis 22 is simultaneously guided and rotated along the arc-shaped guide groove to change the angle of the windshield.

[0045] In some embodiments, a limiting portion 1213 is provided at each end of the arc-shaped guide portion 121 , so that the wind shield 2 is limited at the limiting portion 1213 when it is guided to the end along the arc-shaped guide portion 121 .

[0046] In practice, the wind deflector 1 is a sheet metal part. The main body of the wind deflector 1 is made of iron, which can enhance the structural strength. The sheet metal structure is simple and the mold cost is low. The wind deflector is a plastic part, that is, the guide shaft 22 of the wind deflector can be deformed under extrusion. The arc-shaped guide portion 121 is constructed as an arc-shaped guide groove. The arc-shaped guide groove includes a main groove body 1211 and a first end groove body 1212 and a second end groove body 1214 at both ends of the main groove body 1211. The two ends of the main groove body 1211 are respectively connected to the first end groove body 1212 and the second end groove body 1214. The two ends of the windshield 1214 are connected and form a limiting portion 1213. When the guide shaft 22 rotates and guides from the main slot body 1211 to reach the first end slot body 1212 or the second end slot body 1214, it is squeezed by the limiting portion 1213, enters the end slot body, and is finally limited by the limiting portion 1213. Without applying external force, the rotation position of the windshield is fixed, thereby ensuring the stability of the windshield after it is adjusted to the fixed position, and also ensuring the stability of the windshield under the action of airflow, so that the windshield can block to form an air outlet 17 with a stable size.

[0047] For example, when the rotating shaft 21 of the wind shield is located at a second end slot 1214, the wind shield can be adjusted to a larger angle, and when the rotating shaft 21 of the wind shield is rotated to the first end slot 1212, the wind shield can be adjusted to another smaller angle. Moreover, when the wind shield is located at the position of the main slot 1211, in actual design, the wind shield and the main slot 1211 can be set in the form of extrusion friction. The wind shield can be adjusted to another angle through the force of the extrusion friction. It can be adjusted to different angles according to actual needs, thereby improving the wind-guiding flexibility of the wind-guiding structure.

[0048] In addition, it should be noted that the contact surface between the limiting portion 1213 and the rotating shaft 21 is set to be an arc surface contact, so as to prevent stress concentration on the rotating shaft 21 and enable the guide shaft 22 to enter the first end groove body 1212 or the second end groove body 1214 more smoothly from the main groove body 1211.

[0049] In some embodiments, the wind guide cover 1 is provided with a bottom plate 11 , the wind shield 2 is spaced apart from the bottom plate 11 , and the angle between the wind shield 2 and the bottom plate 11 when rotating is a, and satisfies 0≤a≤90°.

[0050] Among them, the wind guide cover 1 is provided with a base plate 11, and two side plates 12 are connected to both sides of the bottom plate 11. An air guide channel is defined between the base plate 11 and the two side plates 12, and the wind shield is connected between the two side plates 12. The two side plates 12 are both provided with a rotating connection hole 23, and a rotating shaft 21 is provided on both sides of the wind shield. Each rotating shaft 21 is rotatably connected to the rotating connection hole 23 on the corresponding side; at the same time, an arc-shaped guide groove is also provided on one side of the rotating connection hole 23 of each side plate 12, and the guide shaft 22 of the wind shield moves along the arc-shaped guide groove, and the line connecting the center of the first end groove body 1212 of the arc-shaped guide groove and the center of the rotating connection hole 23 is perpendicular to the line connecting the center of the second end groove body 1214 and the rotating connection hole 23, so that the angle of rotation of the rotating shaft 21 along the rotating connection hole 23 is 0-90 degrees.

[0051] Specific, combined Figure 1 and Figure 3 As shown, the rotation connection hole 23 can be set in the middle of the side plate 12 in the height direction, the first end groove 1212 is located on the side plate 12 and on one side of the rotation connection hole 23 in the height direction, wherein the second end groove 1214 is located on the side plate 12 and on the side of the rotation connection hole 23 away from the air outlet 17, when the rotation shaft 21 rotates and the guide shaft 22 of the windshield moves along the arc-shaped guide groove to the first end groove 1212, the windshield and the bottom plate 11 are in a vertical state. At this time, that is, Figure 5 As shown, the size of the air outlet 17 is the area between the bottom of the wind shield and the base plate 11. At this time, the corresponding smart network card set in the PCIe module bracket 3 is a single-width smart network card 31, and the single-width smart network card 31 is opposite to the air outlet 17. The wind shield blocks the wind from above, so that the air outlet at the lower opening is larger, that is, the air inlet into the card structure is larger, so that the single-width smart network card 31 has a better heat dissipation effect.

[0052] When the windshield rotates along the rotating shaft 21 and the guide shaft 22 rotates along the arc-shaped guide groove to the second end groove body 1214, the windshield and the bottom plate 11 are parallel to each other. Figure 2 and Figure 6 As shown, the air outlet 17 is the area on both sides of the wind shield in the height direction of the wind guide cover 1. The height direction of the wind guide cover 1 is Figure 1 and Figure 2In the direction of the height of the side panel 12, the wind direction at the height of the side panel 12 intersects with the direction of the air outlet 17. When the wind shield and the bottom plate 11 are parallel, air is discharged on both sides of the wind shield along the height direction of the wind guide cover 1. At this time, the smart network card set in the card structure can be a double-width smart network card 32. The thickness of the double-width smart network card 32 along the height direction of the wind guide cover 1 is greater than the thickness of the single-width smart network card 31. That is, when the wind shield is parallel to the bottom plate 11, the air outlet 17 is set to the maximum, which can have a better heat dissipation effect when the card structure has a double-width smart network card 32.

[0053] In some embodiments, a support portion 13 is provided on a side of the bottom plate 11 close to the card insertion structure. The support portion 13 is suitable for supporting the smart network card in the card insertion structure.

[0054] In practice, the support portion 13 can be constructed as a protruding plate extending along the bottom plate 11 toward the side of the air outlet 17, and an insulating sheet is provided on the protruding plate. The card insertion structure is located on one side of the air outlet 17 of the air guide cover 1, and an intermediate slot is provided in the card insertion structure. The intermediate slot is used to plug in a smart network card, such as plugging in a single-width smart network card 31 or a double-width smart network card 32. When the single-width smart network card 31 is plugged in, the single-width smart network card 31 can be supported on the insulating sheet, that is, the insulating sheet will contact the single-width smart network card 31, thereby supporting the tail of the single-width smart network card 31 and enhancing the structural stability.

[0055] In some embodiments, the bottom plate 11 is provided with a chassis mounting hole 111 , and the air guide structure is adapted to be connected to the chassis through the chassis mounting hole 111 .

[0056] In practice, when the air guide cover 1 is used in the chassis of an electrical device, the chassis mounting hole 111 and the chassis of the electrical device can be penetrated by a connecting piece to make the air guide cover 1 and the chassis detachable. In this way, the air guide cover 1 can be installed in the direction of the airflow according to actual needs, and the installation position of the air guide cover 1 is related to the position where the plug-in card structure is installed in the chassis, but the air outlet 17 of the air guide cover 1 is always kept facing the plug-in card structure to dissipate heat for the smart network card in the plug-in card structure.

[0057] For example, there can be at least two chassis mounting holes 111, and different chassis mounting holes 111 can be connected to the chassis through connectors. At the same time, when the position of the air guide cover 1 relative to the chassis needs to be adjusted, the air guide cover 1 can be moved to different positions of the chassis, and different chassis mounting holes 111 can be penetrated through connectors to connect to the base plate 11.

[0058] In some embodiments, the air guide structure 100 for electrical equipment further includes a first mounting portion 16 . The first mounting portion 16 is located on a side of the air guide cover 1 away from the card insertion structure. The first mounting portion 16 is used to mount the main air cover 4 .

[0059] Specifically, the heat dissipation fan is located in the main air cover 4, and the air flow in the main air cover 4 flows into the air guide cover 1, and then flows to the air outlet 17 through the main air cover 4, and flows into the plug-in structure through the air outlet 17; the first mounting portion 16 is constructed as a plate body extending and protruding along the side of the bottom plate 11 away from the air outlet 17, and the first mounting portion 16 is provided with a first mounting hole 161. When the main air cover 4 is connected to the air guide cover 1 through the first mounting hole 161 provided by the connecting piece, the main air cover 4 can achieve the effect of gathering wind on the air guide cover 1, and the first mounting portion 16 supports the main air cover 4, and at the same time, the main air cover 4 and the air guide cover 1 can be detachable, which is convenient for the maintenance and replacement of the air guide cover 1 or the main air cover 4.

[0060] Specific reference Figure 7 As shown, the airflow along Figure 7 The left side enters the main wind cover 4, and the main wind cover 4 and the wind guide structure 100 are detachably connected through the first mounting portion 16 and the connecting piece, so that the airflow enters the wind guide structure 100, and the airflow continues to flow out from the air outlet 17 of the wind guide structure 100 toward the right side, and the size of the air outlet 17 can be adjusted by the wind shield. When the wind shield rotates at different angles, the size of the air outlet 17 is different. In the embodiment of the present invention, the wind shield mainly has an angle parallel to the bottom plate 11 and an angle perpendicular to the bottom plate 11. When the wind shield is perpendicular to the bottom plate 11, it has the effect of gathering the airflow toward the lower side of the wind shield. When the wind shield is parallel to the bottom plate 11, the resistance to airflow can be reduced to meet the heat dissipation requirements of the single-width smart network card 31 and the double-width smart network card 32.

[0061] Furthermore, multiple air guide structures 100 are connected in parallel, the main wind cover 4 can be connected to multiple groups of air guide structures 100, and multiple PCIe module brackets 3 (high-speed serial computer expansion bus standard brackets) are connected to one side of the air outlet 17 of the multiple air guide structures 100, and are connected one-to-one, so that the PCIe module bracket 3 can connect to more smart network cards, that is, through the one-to-one correspondence between multiple air guide structures 100 and the smart network cards in multiple PCIe module brackets 3, the different heat dissipation requirements of multiple smart network cards can be met.

[0062] In some embodiments, the windshield 2 is provided with a plurality of heat dissipation holes 24. The plurality of heat dissipation holes 24 are arranged in an array on the windshield, and the windshield has a 40% opening ratio, which can meet the heat dissipation requirements of a PCIe (PCIe Express) card installed on the single-width smart network card 31. A PCIe card is a high-speed expansion card that is connected to a computer system to expand the system's input and output capabilities. The PCIe card provides high-speed data transmission and processing capabilities.

[0063] That is, when the windshield is adjusted to a position perpendicular to the bottom plate 11, the airflow can be mainly directed to the area between the bottom of the windshield and the bottom plate 11, thereby increasing the concentration of airflow toward the single-width smart network card 31 for heat dissipation. However, at the same time, part of the airflow can flow along the heat dissipation holes 24 of the windshield into the PCIe module bracket 3 and dissipate heat for the conventional PCIe card installed above the single-width smart network card 31. In addition, referring to Figure 1 As shown, the diameter of the heat dissipation holes 24 can decrease from the air inlet side of the windshield to the air outlet, thereby improving the airflow collection effect. In addition, the aperture ratio can be adjusted according to actual heat dissipation requirements. When the heat dissipation requirement is high, more heat dissipation holes 24 can be opened, and when the heat dissipation requirement is low, fewer heat dissipation holes 24 can be opened.

[0064] In some embodiments, the air guide cover 1 is further provided with a second mounting portion 14, and the second mounting portion 14 is used for mounting a card insertion structure.

[0065] Reference Figure 2 As shown, the second mounting portion 14 is constructed as a plate body for installing the plug-in structure, which is connected to the top of the side panel 12 and is arranged parallel to the bottom plate 11. The second mounting portion 14 is provided with a second mounting hole 141, which is a threaded hole. Part of the structure of the plug-in structure extends to the position of the second mounting portion 14, and a screw is passed through the second mounting hole 141 and through the plug-in structure to connect the plug-in structure to the air guide cover 1.

[0066] Among them, the plug-in card structure is a PCIe module bracket 3 (high-speed serial computer expansion bus standard bracket). The PCIe module bracket 3 is mainly used for the installation and fixation of high-speed components such as servers and high-end graphics cards. The main function of the PCIe module bracket is to reduce the burden on the motherboard through an additional support structure. This can effectively prevent the smart network card and slot from loosening and deformation due to long-term heavy pressure, thereby affecting the stability of the system and the service life of the hardware.

[0067] Connecting the PCIe module bracket to the air guide cover 1 at the second mounting portion 14 allows the air outlet 17 of the air guide cover 1 to face the PCIe module bracket 3 at a relatively close distance, thereby improving the heat dissipation effect on the smart network card in the PCIe module bracket.

[0068] In addition, the air guide cover 1 of the embodiment of the present invention further has a connecting portion 15, referring to Figure 2As shown, the connecting portion 15 is connected to the side panel 12 on one side of the air outlet 17, and the connecting portion 15 is constructed as a connecting plate, which is bent and connected to the side panel 12. When a double-width smart network card 32 is provided in the card insertion structure, the double-width smart network card 32 is thicker along the height direction of the air guide cover 1, and the card tail of the double-width smart network card 32 has a screw hole. In this form of the air guide cover 1, the connecting part passes through the connecting hole 151 of the connecting portion 15 and the screw hole at the card tail of the double-width smart network card 32, so as to form a connection between the double-width smart network card 32 and the air guide cover 1, thereby supporting the card tail of the double-width smart network card 32.

[0069] An embodiment of the present utility model also discloses a server, including a plug-in card structure, a smart network card and the above-mentioned air guide structure 100 for electrical equipment.
