Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servers, in particular to a blade server. BACKGROUND

[0002] A blade server can be plugged into a rack chassis of standard height, and each blade is actually a system mainboard, which can be regarded as a board card. Each blade is equipped with an on-board hard disk and can independently start an operating system, similar to a separate server operation. In this architecture, each mainboard runs an independent system and serves different user groups without direct association. Through system software, the administrator can still integrate these mainboards into a server cluster. In the cluster mode, all mainboards can be connected to each other to build a high-speed network environment and realize resource sharing to serve the same user group. By adding new blades to the cluster, the overall performance can be significantly improved. In addition, since each blade supports hot swapping, the system can easily perform replacement operations to minimize maintenance time.

[0003] Due to the high density of the board cards of the blade server and the large amount of heat generated, high-power fans are needed for heat dissipation. These fans accelerate the air flow between the board cards to improve the heat dissipation efficiency. However, in this process, the connection structure of the board card and the chassis also needs to withstand the wind force generated by the fan. Long-term wind impact can cause damage to the connection structure, thereby affecting the stable connection of the board card and the chassis. Once the connection stability is damaged, the stress area between the board card and the fan can increase, further increasing the pressure of the wind on the connection structure, thereby accelerating the damage to the connection structure. SUMMARY

[0004] Therefore, the present application provides a blade server to solve the problem that long-term wind impact of the fan of the blade server causes damage to the connection structure.

[0005] The present application provides a blade server, which comprises a box body, a board card device and a heat dissipation device. The box body is internally provided with a mounting groove. The board card device is mounted in the mounting groove. The heat dissipation device comprises a heat dissipation air duct and a negative pressure structure. The heat dissipation air duct and the mounting groove are sequentially arranged along a first direction, and the heat dissipation air duct and the mounting groove are communicated through a communication port. The heat dissipation air duct comprises a first air inlet and a first air outlet. The first air inlet and the first air outlet are respectively arranged at both ends of the heat dissipation air duct along a second direction. The negative pressure structure is used to guide the airflow from the first air inlet to the first air outlet. The first direction is perpendicular to the second direction.

[0006] Since the heat dissipation air duct is arranged adjacent to the mounting groove, and the heat dissipation air duct and the mounting groove are communicated through the communication port, when the negative pressure structure guides the airflow to flow from the first air inlet to the first air outlet, the hot air accumulated in the mounting groove is sucked into the heat dissipation air duct through the communication port under the action of negative pressure, and then the hot air in the heat dissipation air duct is discharged from the first air outlet under the action of the negative pressure structure. The application optimizes the airflow path, improves the efficiency of heat conduction and heat convection, realizes efficient transfer and release of heat, effectively avoids the problem that the fan wind force directly acts on the board card device in the traditional heat dissipation mode, which may cause the board card device to loosen or be unstable, ensures the heat dissipation effect, and also guarantees the stability of the board card device installation and the reliability of long-term operation.

[0007] In an alternative embodiment, the heat dissipation device further comprises a fan structure, the fan structure is arranged at the communication port, and the fan structure comprises a second air inlet and a second air outlet, the second air inlet is arranged towards the board card device, and the first air outlet is located in the heat dissipation air duct.

[0008] Since the second air inlet of the fan structure is arranged towards the board card device, and the first air outlet is located in the heat dissipation air duct, the second air inlet can actively suck the hot air generated by the board card device in the mounting groove, and then the hot air is introduced into the heat dissipation air duct through the second air outlet under the action of the fan structure, and finally discharged from the first air outlet of the heat dissipation air duct; not only accelerates the process of hot air in the mounting groove flowing to the heat dissipation air duct, but also significantly enhances the overall heat dissipation effect.

[0009] In an alternative embodiment, the box is provided with a partition structure, the mounting groove and the heat dissipation air duct are located on two sides of the partition structure along the second direction respectively; the communication port is arranged on the partition structure and extends along the second direction; the fan structure is slidably connected with the communication port; and the board card device extends along the second direction.

[0010] By arranging the partition structure, the interior of the box can be divided into two areas of the mounting groove and the heat dissipation air duct, ensuring the functional independence of the mounting groove and the heat dissipation air duct, and effectively avoiding the interference between them; by slidably connecting the fan structure with the communication port, the fan structure can be flexibly adjusted in position according to actual needs. Since the board card device and the communication port both extend along the second direction, the fan structure can be flexibly moved to the area where the board card device generates the most heat, realizing precise heat dissipation, improving the heat dissipation efficiency, and avoiding the invalid allocation and waste of resources.

[0011] In an alternative embodiment, the heat dissipation device further comprises a power assembly, the power assembly comprising a screw rod and a power mechanism; the screw rod is located in the box body, rotatably connected with the box body, and extends along the second direction; the power mechanism is in transmission connection with the screw rod, for driving the screw rod to rotate; the fan structure is rotatably connected with a helical gear; the helical gear is used for meshing connection with the screw rod.

[0012] Through the cooperation of the screw rod and the helical gear, when the screw rod rotates, the helical gear can be driven to move along the axial direction of the screw rod, and since the screw rod extends along the second direction, the sliding of the fan structure along the second direction in the communication opening is realized, and the adjustment of the position of the fan structure is realized.

[0013] In an alternative embodiment, the fan structure is provided in plurality, the plurality of fan structures are arranged in sequence along the second direction, and the heat dissipation device further comprises a plurality of separation assemblies, each of the fan structures corresponds to one of the separation assemblies; the separation assembly is used for controlling the fan structure to have a separation position separated from the screw rod and a reset position in transmission connection with the screw rod.

[0014] Since the fan structure has the separation position separated from the screw rod and the reset position in transmission connection with the screw rod, when the screw rod is continuously rotated to drive other fan structures to move subsequently, the fan structure already in the separation position will not be affected by the rotation of the screw rod.

[0015] In an alternative embodiment, the separation assembly comprises an elastic member and a telescopic member; the telescopic member is located in the heat dissipation air duct, and the telescopic member and the helical gear are located on two sides adjacent to the fan structure respectively; the fixed end of the telescopic member is connected with the fan structure, and the extension direction of the telescopic end of the telescopic member is perpendicular to the second direction; the telescopic member has a first extension state and a first contraction state; the elastic member is located in the heat dissipation air duct, arranged on the side of the fan structure away from the telescopic member, and connected with the fan structure; the elastic member has a second extension state and a second contraction state; when the telescopic member is in the first extension state, the elastic member is in the second contraction state, and the telescopic member and the elastic member abut against two inner walls of the heat dissipation air duct respectively, and the fan structure is in the separation position; when the telescopic member is in the first contraction state, the elastic member is in the second extension state, and the telescopic member is separated from the inner wall of the heat dissipation air duct, and the fan structure is in the reset position.

[0016] By setting the telescopic part, when the fan structure is moved into position, the telescopic part enters the first elongated state, the thrust force acts on the fan structure, so that it moves away from the side of the screw, at this time, the bevel gear is automatically separated from the screw, and the fan structure enters the separation position, ensuring that the fan structure will not be affected by the rotation of the screw in the fixed state, and the telescopic part and the elastic part are respectively abutted with the two inner walls of the heat dissipation air duct opposite to each other, so as to realize the fixation of the fan structure; by setting the elastic part, when it is necessary to adjust the position of the fan structure, the telescopic part enters the first contracted state, at this time, the elastic part automatically enters the second elongated state, and under the action of the elastic potential, the fan structure is pushed to move to the side close to the screw until the bevel gear is re-engaged with the screw, and the fan structure enters the reset position, at this time, by rotating the screw, the position adjustment of the fan structure can be realized. Through the cooperative action of the telescopic part and the elastic part, not only the position adjustment and stable fixation of the fan structure are realized, but also the flexibility and reliability of the entire heat dissipation device are improved.

[0017] In an alternative embodiment, an air inlet section is arranged at the first air inlet, and the flow cross section of the air inlet section gradually decreases in the direction close to the first air inlet.

[0018] Since the flow cross section of the air inlet section gradually decreases in the direction close to the first air inlet, the flow rate of air gradually increases when passing through this area, thus the flow rate of air entering the heat dissipation air duct is strengthened. Since the flow rate of air inside the heat dissipation air duct is faster and the pressure is smaller, the air in the mounting groove is accelerated to flow to the heat dissipation air duct, thus not only the flow rate of air entering the heat dissipation air duct is strengthened, but also the flow of air from the mounting groove to the inside of the heat dissipation air duct is further enhanced, thereby improving the heat dissipation efficiency of the entire heat dissipation device.

[0019] In an alternative embodiment, the board card device comprises a board card body and a connecting assembly; the board card body is detachably connected with the connecting assembly, and the connecting assembly is detachably connected in the mounting groove.

[0020] Since the board card body is detachably connected with the connecting assembly, and the connecting assembly is detachably connected in the mounting groove, the flexibility and maintainability of the board card device are improved. When the board card body needs to be upgraded, repaired or replaced, the board card body can be detached from the connecting assembly without the need to disassemble the entire system on a large scale; when the connecting assembly itself fails or needs to be upgraded, it can also be conveniently taken out of the mounting groove for maintenance or replacement operation.

[0021] In an alternative embodiment, the connecting assembly comprises a fixing member and a locking member; the fixing member is provided with a connecting groove on one side along the second direction, and the board card body is detachably connected with the connecting groove; the locking member is connected with the end of the fixing member along the first direction, and the locking member protrudes from the board card body; the locking member is provided with a locking groove on one side along the first direction; the mounting groove is provided with a locking buckle, and the locking buckle is rotatably connected with the box body through a torsional spring; the locking buckle has a locking position located in the locking groove and abutting against the groove wall of the locking groove, and an unlocking position separated from the locking member.

[0022] When the board card device slides into the mounting groove along the second direction, the fixing member contacts the locking buckle and drives it to rotate to the unlocking position, avoiding the installation path of the board card device, so as to ensure that the installation process of the board card device is not hindered; after the board card device is installed in place, the locking buckle and the locking groove are in a corresponding position, and the locking buckle is driven to rotate reversely under the elastic force of the torsional spring until it is completely embedded in the locking groove, thereby fixing the board card device, and the physical locking mode enhances the reliability and safety of the installation of the entire board card device.

[0023] In an alternative embodiment, the connecting groove is provided with a conductive contact; and the board card body is provided with a conductive contact piece on one end along the second direction, the conductive contact piece is insertedly connected with the connecting groove and electrically connected with the conductive contact.

[0031] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] The embodiments of the present application will be described below in connection with Figs. 1 to 3 .

[0034] Since the heat dissipation air duct 31 is arranged adjacent to the mounting groove 11, and the heat dissipation air duct 31 and the mounting groove 11 are communicated through the communication port, when the negative pressure structure guides the airflow to flow from the first air inlet 311 to the first air outlet 312, the hot air accumulated in the mounting groove 11 is sucked into the heat dissipation air duct 31 under the action of negative pressure, and then the hot air in the heat dissipation air duct 31 is discharged from the first air outlet 312 under the action of the negative pressure structure. The application optimizes the airflow path, improves the efficiency of heat conduction and heat convection, realizes efficient transfer and release of heat, and effectively avoids the problem that the fan wind force directly acts on the board card device 2 in the traditional heat dissipation mode, which may cause the board card device 2 to be loose or unstable. While ensuring the heat dissipation effect, the stability of the installation of the board card device 2 and the reliability of the long-term operation are also ensured.

[0035] In one embodiment of the present embodiment, the negative pressure structure can be located inside the heat dissipation air duct 31 and arranged between the first air inlet 311 and the first air outlet 312. In another embodiment of the present embodiment, the negative pressure structure can be located outside the heat dissipation air duct 31 and arranged at the position of the first air inlet 311.

[0036] In a specific embodiment, the negative pressure structure is a high-power fan.

[0037] In one embodiment, the heat dissipation device further comprises a fan structure 32, the fan structure 32 is arranged at the communication port, and the fan structure 32 comprises a second air inlet and a second air outlet, the second air inlet is arranged towards the board card device 2, and the first air outlet 312 is located in the heat dissipation air duct 31.

[0038] Since the second air inlet of the fan structure 32 is arranged towards the board card device 2, and the first air outlet 312 is located in the heat dissipation air duct 31, the second air inlet can actively suck the hot air generated by the board card device 2 in the mounting groove 11, and then the hot air is introduced into the heat dissipation air duct 31 through the second air outlet under the action of the fan structure 32, and finally discharged from the first air outlet 312 of the heat dissipation air duct 31. Not only accelerates the process of hot air in the mounting groove 11 flowing to the heat dissipation air duct 31, but also significantly enhances the overall heat dissipation effect.

[0039] In one embodiment, the box 1 is provided with a partition structure 12, the mounting groove 11 and the heat dissipation air duct 31 are located on two sides of the partition structure 12 along the second direction respectively; the communication port is arranged on the partition structure 12 and extends along the second direction; the fan structure 32 is slidably connected with the communication port; and the board card device 2 extends along the second direction.

[0040] By setting the separation structure 12, the interior of the box 1 is divided into two areas of the mounting groove 11 and the heat dissipation air duct 31, the functional independence of the mounting groove 11 and the heat dissipation air duct 31 is ensured, and interference between them is effectively avoided; the fan structure 32 is slidably connected with the communication port, so that the fan structure 32 can be flexibly adjusted in position according to actual needs. Since the board card device 2 and the communication port both extend along the second direction, the fan structure 32 can be flexibly moved to the area where the board card device 2 generates the most heat, precise heat dissipation is achieved, the heat dissipation efficiency is improved, and invalid allocation and waste of resources are avoided.

[0041] In a specific embodiment, the separation structure 12 is a plate-shaped structure.

[0042] In one embodiment, the heat dissipation device further comprises a power assembly, the power assembly comprising a screw rod 331 and a power mechanism; the screw rod 331 is located in the box 1 and rotatably connected with the box 1 and extends along the second direction; the power mechanism is in transmission connection with the screw rod 331 and used for driving the screw rod 331 to rotate; the fan structure 32 is rotatably connected with a helical gear 34; the helical gear 34 is used for meshing connection with the screw rod 331.

[0043] Through cooperation of the screw rod 331 and the helical gear 34, when the screw rod 331 rotates, the helical gear 34 can be driven to move along the axial direction of the screw rod 331, and since the screw rod 331 extends along the second direction, the sliding of the fan structure 32 along the second direction in the communication port is realized, and adjustment of the position of the fan structure 32 is realized.

[0044] In a specific embodiment, the power mechanism can be a rotating handle or an electric motor.

[0045] Specifically, the power mechanism is a rotating handle, which is arranged outside the box 1 and rotatably connected with the box 1, and the end of the screw rod 331 penetrates through a through hole on the box 1 and connected with the rotating handle.

[0046] In an alternative embodiment, the fan structure 32 is provided in plurality, the plurality of fan structures 32 are arranged in sequence along the second direction, the heat dissipation device further comprises a plurality of separation assemblies, each of the fan structures 32 corresponds to a group of the separation assemblies; the separation assembly is used for controlling the fan structure 32 to have a separation position separated from the screw rod 331 and a reset position in transmission connection with the screw rod 331.

[0047] Since the fan structure 32 has the separated position separated from the screw rod 331 and the reset position driven by the screw rod 331, when the screw rod 331 continues to rotate to drive other fan structures 32 to move, the fan structure 32 already in the separated position is not affected by the rotation of the screw rod 331.

[0048] In an embodiment, the separating assembly further comprises a telescopic member 351 and an elastic member; the telescopic member 351 is located in the heat dissipation air duct 31 and is located on the two sides adjacent to the fan structure 32 respectively with the bevel gear 34; the fixed end of the telescopic member 351 is connected with the fan structure 32, and the telescopic end of the telescopic member 351 extends in a direction perpendicular to the second direction; the telescopic member 351 has a first extended state and a first contracted state; the elastic member is located in the heat dissipation air duct 31 and is arranged on the side of the fan structure 32 away from the telescopic member 351 and is connected with the fan structure 32; the elastic member has a second extended state and a second contracted state; when the telescopic member 351 is in the first extended state, the elastic member is in the second contracted state, and the telescopic member 351 and the elastic member abut against the two inner walls of the heat dissipation air duct 31 opposite to each other respectively, and the fan structure 32 is in the separated position; when the telescopic member 351 is in the first contracted state, the elastic member is in the second extended state, and the telescopic member 351 is separated from the inner wall of the heat dissipation air duct 31, and the fan structure 32 is in the reset position.

[0049] By arranging the telescopic member 351, when the fan structure 32 is moved to the position, the telescopic member 351 enters the first extended state, and the thrust force of the telescopic member 351 acts on the fan structure 32 to move the fan structure 32 to the side away from the screw rod 331, at this time, the bevel gear 34 is automatically separated from the screw rod 331, and the fan structure 32 enters the separated position, so that the fan structure 32 is not affected by the rotation of the screw rod 331 in the fixed state, and the telescopic member 351 and the elastic member abut against the two inner walls of the heat dissipation air duct 31 opposite to each other respectively, so that the fan structure 32 is fixed; by arranging the elastic member, when it is necessary to adjust the position of the fan structure 32, the telescopic member 351 enters the first contracted state, at this time, the elastic member automatically enters the second extended state, and the elastic member pushes the fan structure 32 to move to the side close to the screw rod 331 under the action of the elastic potential energy until the bevel gear 34 is re-engaged with the screw rod 331, and the fan structure 32 enters the reset position, at this time, the screw rod 331 is rotated to drive the fan structure 32 to adjust the position. Through the cooperation of the telescopic member 351 and the elastic member, the adjustment and stable fixation of the position of the fan structure 32 are realized, and the flexibility and reliability of the entire heat dissipation device are improved.

[0050] In a specific embodiment, when the telescopic member 351 is in the first extended state, the telescopic member 351 abuts against the first inner wall of the heat dissipation air duct 31, and the length of the telescopic member 351 is greater than the distance between the screw rod 331 and the first inner wall, thus when the telescopic member 351 is in the first extended state, the telescopic member 351 helps to push the fan structure 32 to the side away from the screw rod 331, so as to separate the helical gear 34 from the screw rod 331.

[0051] In a specific embodiment, the elastic member is a spring.

[0052] In a specific embodiment, the side wall of the fan structure 32 is provided with a mounting hole, and the end of the elastic member connected with the fan structure 32 is located in the mounting hole. When the elastic member is in the second contracted state, the elastic member is contracted in the mounting hole, and at this time, the other end of the elastic member and the fan structure 32 both abut against the second inner wall of the heat dissipation air duct 31, so as to ensure the fixing effect of the fan structure 32. Specifically, the first inner wall and the second inner wall are oppositely arranged.

[0053] In a specific embodiment, the side of the fan structure 32 close to the screw rod 331 is provided with a connecting rod, and the helical gear 34 is rotatably connected to the connecting rod.

[0054] In a specific embodiment, the second air inlet of the fan structure 32 can be arranged protruding from the partition structure 12 and extending into the mounting groove 11. Specifically, the fan structure 32 is located in the heat dissipation air duct 31, and the width of the fan structure 32 in the third direction is greater than the width of the second air inlet in the third direction. The third direction is perpendicular to the first direction and the second direction.

[0055] In one embodiment of the present embodiment, the screw rod 331 and the fan structure 32 are spaced apart along the first direction, and the telescopic member 351 and the elastic member are arranged on the two sides of the fan structure 32 along the third direction, and the first inner wall and the second inner wall are oppositely arranged along the third direction. When the telescopic member 351 is in the first extended state, the telescopic member 351 pushes the fan structure 32 to slide along the third direction. Specifically, the width of the fan structure 32 in the third direction is greater than the width of the communication port in the third direction, and the width of the second air inlet in the third direction is less than the width of the communication port in the third direction, so as to ensure that when the fan structure 32 is pushed by the telescopic member 351 to abut against the inner wall of the heat dissipation air duct 31, the second air inlet can still remain in the position of the communication port and draw air in the mounting groove 11.

[0056] In another embodiment of the present embodiment, the screw rod 331 and the fan structure 32 are spaced apart along the third direction, and the telescopic member 351 and the elastic member are arranged on the two sides of the fan structure 32 along the first direction, and the first inner wall and the second inner wall are oppositely arranged along the first direction. Specifically, the screw rod 331 can be located in the mounting groove 11 or in the heat dissipation air duct 31.

[0057] Preferably, the screw 331 is driven by a motor, the telescopic piece 351 is an electric telescopic rod, the server includes a control system, a plurality of detection devices are arranged on the board card device 2 along the second direction, the detection devices are integrated with temperature sensors and in-place sensors, the temperature sensors, the in-place sensors, the electric telescopic rod and the motor are in communication connection with the control system; when the temperature sensor of a certain area on the board card device 2 detects that the temperature exceeds the preset value, the control system first identifies and instructs the electric telescopic rod of the fan structure 32 located in the area with a temperature lower than the preset value to enter the first contraction state, so that the fan structure 32 located in the low-temperature area is separated from the inner wall of the heat dissipation air duct 31 and is in the reset position. Subsequently, the control system controls the motor to start and drive the screw 331 to rotate, driving the fan structure 32 to start moving along the second direction, when the fan structure 32 reaches the high-temperature area indicated by the temperature sensor, the in-place sensor will send a confirmation signal to the control system in time. After receiving the signal of the in-place sensor, the control system controls the motor to stop running, and then controls the electric telescopic rod to switch to the first elongation state, so that the fan structure 32 abuts against the inner wall of the heat dissipation air duct 31 and is in the separation position. The automation control of the movement of the fan structure 32 is realized, without the need for manual intervention, improving the efficiency and accuracy of the heat dissipation management, ensuring that the heat dissipation resources are effectively allocated to the positions that need them most, avoiding the waste of resources, improving the heat dissipation efficiency, and enhancing the flexibility and adaptability of the heat dissipation device.

[0058] In one embodiment, the first air inlet 311 is provided with an air inlet section 36, and the flow cross section of the air inlet section 36 gradually decreases in the direction close to the first air inlet 311.

[0059] Since the flow cross section of the air inlet section 36 gradually decreases in the direction close to the first air inlet 311, the flow rate of air gradually increases when passing through this area, thus strengthening the flow rate of air entering the inside of the heat dissipation air duct 31. Since the air flow rate in the heat dissipation air duct 31 is faster and the pressure is smaller, the air in the mounting groove 11 is accelerated to flow to the inside of the heat dissipation air duct 31, not only strengthening the flow rate of air entering the inside of the heat dissipation air duct 31, but also further enhancing the flow of air from the mounting groove 11 to the inside of the heat dissipation air duct 31, thereby improving the heat dissipation efficiency of the entire heat dissipation device.

[0060] In one embodiment, the air inlet section 36 is arranged outside the box body 1.

[0061] By setting the air inlet section 36 outside the cabinet 1, not only the more open space environment outside the cabinet 1 is utilized, the obstruction and limitation of the internal structure are effectively avoided, but also the smoothness and freedom of air flow are greatly promoted, the air inlet area is increased, more sufficient air source is provided for the heat dissipation air duct 31, the air flow into the heat dissipation air duct 31 is increased, and the heat dissipation efficiency is improved.

[0062] In one embodiment, the board card device 2 comprises a board card body 21 and a connecting assembly 22; the board card body 21 is detachably connected with the connecting assembly 22, and the connecting assembly 22 is detachably connected in the mounting slot 11.

[0063] Since the board card body 21 is detachably connected with the connecting assembly 22, and the connecting assembly 22 is detachably connected in the mounting slot 11, the flexibility and maintainability of the board card device 2 are improved. When the board card body 21 needs to be upgraded, repaired or replaced, the board card body 21 can be detached from the connecting assembly 22 without disassembling the entire system; when the connecting assembly 22 itself fails or needs to be upgraded, it can also be conveniently taken out of the mounting slot 11 for maintenance or replacement operation.

[0064] In one embodiment, the connecting assembly 22 comprises a fixing member 221 and a locking member 222; the fixing member 221 is provided with a connecting groove on one side along the second direction, and the board card body 21 is detachably connected with the connecting groove; the locking member 222 is connected with the end of the fixing member 221 along the first direction, and the locking member 222 protrudes from the board card body 21; the locking member 222 is provided with a locking groove 2221 on one side along the first direction; the mounting slot 11 is provided with a locking buckle 13, which is rotatably connected with the cabinet 1 through a torsion spring, and the locking buckle 13 has a locking position located in the locking groove 2221 and abutting against the groove wall of the locking groove 2221, and an unlocking position separated from the locking member 222.

[0065] Since the locking buckle 13 is rotatably connected with the cabinet 1 through a torsion spring, when the board card device 2 slides along the second direction to be installed in the mounting slot 11, the fixing member 221 contacts the locking buckle 13 and drives it to rotate to the unlocking position, avoiding the installation path of the board card device 2, so as to ensure that the installation process of the board card device 2 is not hindered; after the board card device 2 is installed in place, the locking buckle 13 and the locking groove 2221 are in corresponding positions, and the locking buckle 13 is driven to rotate reversely under the elastic force of the torsion spring until it is completely embedded in the locking groove 2221, realizing the fixation of the board card device 2, and enhancing the reliability and safety of the installation of the entire board card device 2 through physical locking.

[0066] In a specific embodiment, the locking groove 2221 is an arc groove.

[0067] Preferably, an arc-shaped slide is provided on the side wall of the installation groove 11, and the arc-shaped slide is aligned with the side wall of the installation groove 11. Fig. 2 The arcuate profile of the locking groove 2221 is shown to match the torsion spring. A protruding stopper is provided on the end of the locking member 222 facing away from the torsion spring. The stopper is located on the side of the arcuate slideway and is slidably disposed within the arcuate slideway. The arcuate slideway and the stopper limit the rotation angle of the locking buckle 13, effectively preventing the risk of unexpected loosening or displacement of the locking buckle 13 from the predetermined locking position after reaching the locked state. This significantly enhances the stability and operational reliability of the board and card assembly 2 after installation. The limiting action of the arcuate slideway and the stopper not only enhances the locking effect of the locking buckle 13 but also ensures a tight connection between the board and card assembly 2 and the housing 1 through physical constraints.

[0068] Preferably, one end of the limit block is connected to the locking buckle 13, and the other end passes through the arc slide and extends to the outside of the box body 1, so that the purpose of visually judging whether the board clamping device 2 has been correctly installed is achieved by observing the sliding position of the limit block in the arc slide. Fig. 2 Rotate the limit block in the counterclockwise direction as shown until the locking buckle 13 reaches the unlocked state (as shown in FIG. Fig. 2 As shown), the board device 2 can be disassembled at this time.

[0069] In a specific embodiment, in the natural state, the locking buckle 13 is in a locked position under the action of the torsion spring. Fig. 2 The diagram shows a structure in which the board clamping device 2 is installed in place and the locking buckle 13 has not yet been rotated to the locking position under the action of the torsion spring.

[0070] In a specific embodiment, two locking members 222 are provided. The two locking members 222 are respectively provided at two ends of the fixing member 221 along the first direction. Each locking member 222 is correspondingly provided with a locking buckle 13 .

[0071] In a specific embodiment, one or more board devices 2 are provided in the blade server. When multiple board devices 2 are provided in the blade server, multiple installation slots 11 are provided in the box 1. The multiple installation slots 11 are arranged in sequence along the third direction, and the locking buckles 13 are fixed on the slot walls of the installation slots 11. Each board device 2 is installed in a corresponding installation slot 11.

[0072] Specifically, a partition is arranged between two adjacent installation grooves 11, which not only divides the box 1 into multiple independent installation grooves 11, but also serves as a heat isolation barrier to reduce the mutual influence of adjacent board card devices 2 when generating heat, so that the heat generated by the board card device 2 with high heat generation temperature can be effectively isolated, and the adverse effect on the board card device 2 with low heat generation temperature around can be avoided.

[0073] Specifically, the partition structure 12 is provided with multiple communication openings, which correspond to the multiple installation grooves 11 one by one, and each communication opening is provided with a set of fan structures 32 and a set of power components.

[0074] In one embodiment, the connecting groove is provided with a conductive contact 2211; the board card body 21 is provided with a conductive contact piece at one end along the second direction, the conductive contact piece is connected with the connecting groove in a plug-in manner, and the conductive contact piece is electrically connected with the conductive contact 2211.

[0075] Through the arrangement of the conductive contact 2211 and the conductive contact piece, the electrical connection between the board card body 21 and the fixing part 221 is realized, which is helpful for the connection between the board card body 21 and the system.

[0076] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
