Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a blade server. Background Art

[0002] Blade servers can be installed with multiple card-type server units, i.e. "blades", in a standard height rack chassis. Each "blade" is actually a system motherboard, which can also be regarded as a board. They are each equipped with an "onboard" hard disk and can independently start the operating system, similar to the operation of a separate server. Under this architecture, each motherboard runs an independent system, serves different user groups, and has no direct connection with each other. Through system software, administrators can still integrate these motherboards into a server cluster. In cluster mode, all motherboards can be connected to each other to jointly build a high-speed network environment and share resources 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 plugging, the system can be easily replaced, thereby minimizing maintenance time.

[0003] Since blade servers have high density of boards and generate a lot of heat, they need to rely on high-power fans for heat dissipation. These fans improve heat dissipation efficiency by accelerating the air flow between boards. However, in this process, the connection structure between the board and the chassis must also withstand the wind force generated by the fan. Long-term wind impact may cause damage to the connection structure, which in turn affects the stable connection between the board and the chassis. Once the connection stability is damaged, the force-bearing area between the board and the fan may increase, further increasing the pressure of wind on the connection structure, thereby accelerating the damage of the connection structure. Summary of the invention

[0004] In view of this, the present invention provides a blade server to solve the problem that the connection structure of the fan of the blade server is damaged due to long-term wind impact.

[0005] The present invention provides a blade server, comprising a box body, a board device and a heat dissipation device; a mounting groove is arranged inside the box body; the board device is installed in the mounting groove; the heat dissipation device comprises a heat dissipation duct and a negative pressure structure, the heat dissipation duct and the mounting groove are arranged in sequence along a first direction, and the heat dissipation duct and the mounting groove are connected through a connecting port; the heat dissipation duct comprises a first air inlet and a first air outlet, the first air inlet and the first air outlet are respectively arranged at two ends of the heat dissipation 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 duct and the mounting groove are arranged adjacent to each other and are connected to the heat dissipation duct and the mounting groove are connected through the connecting port, when the negative pressure structure guides the airflow from the first air inlet to the first air outlet, the hot air accumulated in the mounting groove is sucked into the heat dissipation duct through the connecting port under the action of negative pressure, and then under the action of the negative pressure structure, the hot air in the heat dissipation duct is discharged from the first air outlet. The present application improves the efficiency of heat conduction and heat convection by optimizing the airflow path, realizes the efficient transfer and release of heat, and effectively avoids the problem of looseness or instability of the board device caused by the direct action of the fan wind force on the board device in the traditional heat dissipation method. While ensuring the heat dissipation effect, it also guarantees the stability of the installation of the board device and the reliability of long-term operation.

[0007] In an optional embodiment, the heat dissipation device also includes a fan structure, which is arranged at the connecting port, and the fan structure includes a second air inlet and a second air outlet, the second air inlet is arranged toward the board device, and the first air outlet is located in the heat dissipation duct.

[0008] Since the second air inlet of the fan structure is arranged toward the board device and the first air outlet is located in the heat dissipation duct, the second air inlet can actively inhale the hot air generated by the board device in the installation slot, and then the hot air is introduced into the heat dissipation 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 duct; this not only accelerates the process of hot air in the installation slot flowing to the heat dissipation duct, but also significantly enhances the overall heat dissipation effect.

[0009] In an optional embodiment, a partition structure is provided in the box body, and the mounting groove and the heat dissipation duct are respectively located on both sides of the partition structure along the second direction; the connecting port is arranged on the partition structure and extends along the second direction; the fan structure is slidably connected to the connecting port; and the board device extends along the second direction.

[0010] By setting up a partition structure, it is helpful to divide the interior of the box into two areas: the installation slot and the heat dissipation duct, ensuring the functional independence of the installation slot and the heat dissipation duct, and effectively avoiding mutual interference; the fan structure is slidably connected to the connecting port, so that the fan structure can flexibly adjust its position according to actual needs. Since the board device and the connecting port both extend along the second direction, the fan structure can be flexibly moved to the area where the board device is most heated, achieving precise heat dissipation, improving heat dissipation efficiency, and avoiding ineffective allocation and waste of resources.

[0011] In an optional embodiment, the heat dissipation device also includes a power assembly, which includes a screw and a power mechanism; the screw is located in the housing, rotatably connected to the housing, and extends along the second direction; the power mechanism is transmission-connected to the screw for driving the screw to rotate; a bevel gear is rotatably connected to the fan structure; the bevel gear is used to mesh with the screw.

[0012] Through the cooperation of the screw and the bevel gear, when the screw rotates, the bevel gear can be driven to move along the axial direction of the screw. Since the screw extends along the second direction, the fan structure can slide along the second direction in the connecting port, thereby adjusting the position of the fan structure.

[0013] In an optional embodiment, the fan structure is provided with a plurality of fan structures, and the plurality of fan structures are arranged in sequence along the second direction. The heat dissipation device also includes a plurality of groups of separation components, and each group of the fan structures corresponds to a group of the separation components; the separation components are used to control the fan structure to have a separation position separated from the screw rod, and a reset position of the screw rod transmission connection.

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

[0015] In an optional embodiment, the separation component includes a telescopic member and an elastic member; the telescopic member is located in the heat dissipation duct, and the telescopic member and the bevel gear are respectively located on two adjacent sides of the fan structure; the fixed end of the telescopic member is connected to 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 extended state and a first contracted state; the elastic member is located in the heat dissipation duct, arranged on a side of the fan structure away from the telescopic member, and connected to the fan structure; the elastic member has a second extended state and a second contracted state; when the telescopic member is in the first extended state, the elastic member is in the second contracted state, and the telescopic member and the elastic member are respectively abutted against two opposite inner walls of the heat dissipation duct, and the fan structure is in the separation position; when the telescopic member is in the first contracted state, the elastic member is in the second extended state, and the telescopic member is separated from the inner wall of the heat dissipation duct, and the fan structure is in the reset position.

[0016] By setting a telescopic member, when the fan structure moves into position, the telescopic member enters a first extension state, and its thrust acts on the fan structure to move it to the side away from the screw. At this time, the bevel gear and the screw are automatically separated, and the fan structure enters a separation position, ensuring that the fan structure will not be affected by the rotation of the screw in a fixed state, and the telescopic member and the elastic member are respectively in contact with the two inner walls opposite to the heat dissipation duct, thereby fixing the fan structure; by setting an elastic member, when the position of the fan structure needs to be adjusted, the telescopic member enters a first contraction state, and the elastic member automatically enters a second extension state, and pushes the fan structure to move to the side close to the screw under the action of elastic potential energy, until the bevel gear and the screw are re-engaged, and the fan structure enters a reset position, at which time the fan structure can be driven to adjust its position by rotating the screw. The synergistic effect of the telescopic member and the elastic member not only realizes the adjustment and firm fixation of the fan structure position, but also improves the flexibility and reliability of the entire heat dissipation device.

[0017] In an optional embodiment, an air inlet section is provided at the first air inlet, and a flow cross-section of the air inlet section gradually decreases toward the first air inlet.

[0018] Since the flow cross-section of the air inlet section gradually decreases towards the first air inlet, as the flow cross-section decreases, the flow velocity of the air passing through this area will gradually increase, thereby increasing the flow velocity of the air entering the heat dissipation duct. Since the air flow velocity inside the heat dissipation duct is faster and the pressure is smaller, the air in the installation slot is accelerated to flow toward the heat dissipation duct, which not only increases the flow velocity of the air entering the heat dissipation duct, but also further enhances the flow of air from the installation slot to the inside of the heat dissipation duct, thereby improving the heat dissipation efficiency of the entire heat dissipation device.

[0019] In an optional embodiment, the board device includes a board body and a connecting component; the board body is detachably connected to the connecting component, and the connecting component is detachably connected in the installation slot.

[0020] Since the board body is detachably connected to the connection component, and the connection component is detachably connected to the installation slot, the flexibility and maintainability of the board device are improved. When the board body needs to be upgraded, repaired or replaced, the board body can be removed from the connection component without large-scale disassembly of the entire system; when the connection component itself fails or needs to be upgraded, it can also be easily taken out of the installation slot for maintenance or replacement.

[0021] In an optional embodiment, the connecting assembly includes a fixing member and a locking member; a connecting groove is provided on one side of the fixing member along the second direction, and the board body is detachably connected to the connecting groove; the locking member is connected to the end of the fixing member along the first direction, and the locking member protrudes from the board body; a locking groove is provided on one side of the locking member along the first direction; a locking buckle is provided in the installation groove, and the locking buckle is rotatably connected to the box body through a torsion spring, and 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] Since the locking buckle is rotatably connected to the box body through the torsion spring, when the board device slides along the second direction into the installation groove, the fixing member contacts the locking buckle and pushes it to rotate to the unlocking position, avoiding the installation path of the board device, thereby ensuring that the installation process of the board device is not hindered in any way; when the board device is installed in place, the locking buckle and the locking groove are in corresponding positions, and the locking buckle is driven to rotate in the opposite direction under the elastic force of the torsion spring until it is completely embedded in the locking groove, thereby fixing the board device, and enhancing the reliability and safety of the entire board device installation through physical locking.

[0023] In an optional embodiment, a conductive contact is provided in the connection slot; a conductive contact is provided at one end of the board body along the second direction, and the conductive contact is plug-connected to the connection slot and electrically connected to the conductive contact.

[0024] By providing the conductive contacts and the conductive contact sheets, electrical connection between the board body and the fixing member is achieved, which helps to achieve connection between the board body and the system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0033] According to an embodiment of the present invention, on the one hand, a blade server is provided, comprising a housing 1, a board device 2 and a heat dissipation device; a mounting groove 11 is provided inside the housing 1; the board device 2 is installed in the mounting groove 11; the heat dissipation device comprises a heat dissipation duct 31 and a negative pressure structure, the heat dissipation duct 31 and the mounting groove 11 are arranged in sequence along a first direction, and the heat dissipation duct 31 and the mounting groove 11 are connected through a connecting port; the heat dissipation duct 31 comprises a first air inlet 311 and a first air outlet 312, the first air inlet 311 and the first air outlet 312 are respectively arranged at two ends of the heat dissipation duct 31 along a second direction; the negative pressure structure is used to guide the airflow from the first air inlet 311 to the first air outlet 312; the first direction is perpendicular to the second direction.

[0034] Since the heat dissipation duct 31 is arranged adjacent to the mounting groove 11 and the heat dissipation duct 31 is connected to the mounting groove 11 through the connecting port, when the negative pressure structure guides the airflow 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 duct 31 through the connecting port under the action of the negative pressure, and then under the action of the negative pressure structure, the hot air in the heat dissipation duct 31 is discharged from the first air outlet 312. The present application improves the efficiency of heat conduction and heat convection by optimizing the airflow path, realizes the efficient transfer and release of heat, and effectively avoids the problem of looseness or instability of the board device 2 caused by the direct action of the fan wind force on the board device 2 in the traditional heat dissipation method. While ensuring the heat dissipation effect, it also guarantees the stability of the installation of the board device 2 and the reliability of long-term operation.

[0035] In one implementation of this embodiment, the negative pressure structure may be located inside the heat dissipation duct 31, and disposed between the first air inlet 311 and the first air outlet 312. In another implementation of this embodiment, the negative pressure structure may be located outside the heat dissipation duct 31, and disposed at the location where the first air inlet 311 is located.

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

[0037] In one embodiment, the heat dissipation device also includes a fan structure 32, which is arranged at the connecting port, and the fan structure 32 includes a second air inlet and a second air outlet, the second air inlet is arranged toward the board device 2, and the first air outlet 312 is located in the heat dissipation duct 31.

[0038] Since the second air inlet of the fan structure 32 is arranged toward the board device 2 and the first air outlet 312 is located in the heat dissipation duct 31, the second air inlet can actively inhale the hot air generated by the board device 2 in the installation slot 11, and then the hot air is introduced into the heat dissipation 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 duct 31; this not only accelerates the process of hot air in the installation slot 11 flowing to the heat dissipation duct 31, but also significantly enhances the overall heat dissipation effect.

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

[0040] By setting the partition structure 12, it is helpful to divide the interior of the box body 1 into two areas, the installation slot 11 and the heat dissipation duct 31, to ensure the functional independence of the installation slot 11 and the heat dissipation duct 31, and effectively avoid mutual interference; the fan structure 32 is slidably connected to the connecting port, so that the fan structure 32 can flexibly adjust its position according to actual needs. Since the board device 2 and the connecting port both extend along the second direction, the fan structure 32 can be flexibly moved to the area where the board device 2 is most heated, so as to achieve precise heat dissipation, improve heat dissipation efficiency, and avoid ineffective allocation and waste of resources.

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

[0042] In one embodiment, the heat dissipation device also includes a power assembly, which includes a screw 331 and a power mechanism; the screw 331 is located in the housing 1, rotatably connected to the housing 1, and extends along the second direction; the power mechanism is transmission-connected to the screw 331, and is used to drive the screw 331 to rotate; a bevel gear 34 is rotatably connected to the fan structure 32; the bevel gear 34 is used to mesh with the screw 331.

[0043] Through the cooperation between the screw 331 and the bevel gear 34, when the screw 331 rotates, the bevel gear 34 can be driven to move along the axial direction of the screw 331. Since the screw 331 extends along the second direction, the fan structure 32 can slide in the connecting port along the second direction, thereby realizing the adjustment of the position of the fan structure 32.

[0044] In a specific implementation, the power mechanism may be a rotary handle or a motor.

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

[0046] In an optional embodiment, the fan structure 32 is provided in plurality, and the plurality of fan structures 32 are arranged in sequence along the second direction, and the heat dissipation device further includes a plurality of groups of separation components, and each group of the fan structures 32 corresponds to a group of the separation components; the separation components are used to control the fan structure 32 to have a separation position separated from the screw 331, and a reset position in which the screw 331 is transmission-connected.

[0047] Since the fan structure 32 has a separation position separated from the screw 331 and a reset position in transmission connection with the screw 331 , when the screw 331 is subsequently rotated to drive other fan structures 32 to move, the fan structure 32 that is already in the separation position will not be affected by the rotation of the screw 331 .

[0048] In one embodiment, the separation component further includes a telescopic member 351 and an elastic member; the telescopic member 351 is located in the heat dissipation duct 31, and the telescopic member 351 and the bevel gear 34 are respectively located on two sides adjacent to the fan structure 32; the fixed end of the telescopic member 351 is connected to the fan structure 32, and the extension direction of the telescopic end of the telescopic member 351 is 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 duct 31, and is arranged on a side of the fan structure 32 away from the telescopic member 351, and is connected to the fan structure 32. The fan structure 32 is connected; 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 are respectively abutted against two inner walls opposite to the heat dissipation duct 31, 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 duct 31, and the fan structure 32 is in the reset position.

[0049] By setting the telescopic member 351, when the fan structure 32 moves into place, the telescopic member 351 enters the first extended state, and its thrust acts on the fan structure 32 to move it to the side away from the screw 331. At this time, the bevel gear 34 and the screw 331 are automatically separated, and the fan structure 32 enters the separated position, ensuring that the fan structure 32 will not be affected by the rotation of the screw 331 in the fixed state, and the telescopic member 351 and the elastic member are respectively abutted against the two opposite inner walls of the heat dissipation duct 31, thereby fixing the fan structure 32; by setting the elastic member, when the position of the fan structure 32 needs to be adjusted, the telescopic member 351 enters the first contracted state, at which time the elastic member automatically enters the second extended state, and under the action of elastic potential energy, pushes the fan structure 32 to move to the side close to the screw 331 until the bevel gear 34 and the screw 331 are re-engaged, and the fan structure 32 enters the reset position, at which time the position of the fan structure 32 can be adjusted by rotating the screw 331. The coordinated action of the telescopic member 351 and the elastic member not only realizes the adjustment and firm fixation of the position of the fan structure 32 , but also improves the flexibility and reliability of the entire heat dissipation device.

[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 duct 31, and the length of the telescopic member 351 is greater than the distance between the screw 331 and the first inner wall. Therefore, when the telescopic member 351 is in the first extended state, it helps to push the fan structure 32 to the side away from the screw 331, thereby realizing the separation of the bevel gear 34 and the screw 331.

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

[0052] In a specific embodiment, a mounting hole is provided on the side wall of the fan structure 32, and one end of the elastic member connected to the fan structure 32 is located in the mounting hole. When the elastic member is in the second contracted state, the elastic member contracts in the mounting hole. At this time, the fan structure 32 and the other end of the elastic member are both in contact with the second inner wall of the heat dissipation duct 31, thereby ensuring the fixing effect of the fan structure 32; specifically, the first inner wall and the second inner wall are arranged relative to each other.

[0053] In a specific implementation, a connecting rod is provided on one side of the fan structure 32 close to the screw rod 331 , and the bevel 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 protruded from the partition structure 12 and extended into the mounting groove 11. Specifically, the fan structure 32 is located in the heat dissipation 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 implementation of the present embodiment, the screw 331 and the fan structure 32 are spaced apart along the first direction, and the telescopic member 351 and the elastic member are respectively arranged on both sides of the fan structure 32 along the third direction, and the first inner wall and the second inner wall are arranged relatively along the third direction. When the telescopic member 351 is in the first extended state, it will push 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 connecting port in the third direction, and the width of the second air inlet in the third direction is less than the width of the connecting port in the third direction, ensuring that when the fan structure 32 is pushed by the telescopic member 351 to closely abut against the inner wall of the heat dissipation duct 31, the second air inlet can still remain at the position of the connecting port and extract air from the mounting groove 11.

[0056] In another implementation of this embodiment, the screw 331 and the fan structure 32 are spaced apart along the third direction, the telescopic member 351 and the elastic member are respectively arranged on both sides of the fan structure 32 along the first direction, and the first inner wall and the second inner wall are arranged opposite to each other along the first direction. Specifically, the screw 331 can be located in the installation groove 11 or in the heat dissipation duct 31.

[0057] Preferably, the screw rod 331 is driven by a motor, the telescopic member 351 is an electric telescopic rod, the blade server includes a control system, and a plurality of detection devices are arranged along the second direction on the board device 2, the detection device integrates a temperature sensor and an in-place sensor, and the temperature sensor, the in-place sensor, the electric telescopic rod and the motor are all connected to the control system in communication; when the temperature sensor in a certain area of ​​the board 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 where the temperature is 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 duct 31 and is in the reset position. Subsequently, the control system controls the motor to start, drives the screw rod 331 to rotate, and drives 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 immediately send a confirmation signal to the control system. After receiving the signal from 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 extension state, so that the fan structure 32 abuts against the inner wall of the heat dissipation duct 31 and is in a separated position. Automatic control of the movement of the fan structure 32 is achieved without manual intervention, which improves the efficiency and accuracy of heat dissipation management, ensures that heat dissipation resources are effectively allocated to the locations where they are most needed, avoids waste of resources, improves heat dissipation efficiency, and enhances the flexibility and adaptability of the heat dissipation device.

[0058] In one embodiment, an air inlet section 36 is disposed at the first air inlet 311 , and a flow cross-section of the air inlet section 36 gradually decreases toward the first air inlet 311 .

[0059] Since the flow cross-section of the air inlet section 36 gradually decreases towards the first air inlet 311, as the flow cross-section decreases, the flow velocity of the air passing through this area will gradually increase, thereby increasing the flow velocity of the air entering the heat dissipation duct 31. Since the air flow velocity inside the heat dissipation duct 31 is faster and the pressure is smaller, the air in the installation groove 11 is accelerated to flow toward the heat dissipation duct 31, which not only increases the flow velocity of the air entering the heat dissipation duct 31, but also further enhances the flow of the air from the installation groove 11 to the inside of the heat dissipation 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 box body 1, not only the more open space environment outside the box body 1 is utilized, effectively avoiding the obstruction and limitation of the internal structure, but also the smoothness and freedom of air flow are greatly promoted, the air inlet area is increased, and a more sufficient air source is provided for the heat dissipation duct 31, which increases the air flow entering the heat dissipation duct 31 and improves the heat dissipation efficiency.

[0062] In one embodiment, the board device 2 includes a board body 21 and a connecting component 22 ; the board body 21 is detachably connected to the connecting component 22 , and the connecting component 22 is detachably connected to the installation slot 11 .

[0063] Since the board body 21 is detachably connected to the connection component 22, and the connection component 22 is detachably connected to the installation slot 11, the flexibility and maintainability of the board device 2 are improved. When the board body 21 needs to be upgraded, repaired or replaced, the board body 21 can be removed from the connection component 22 without large-scale disassembly of the entire system; when the connection component 22 itself fails or needs to be upgraded, it can also be conveniently taken out of the installation slot 11 for maintenance or replacement.

[0064] In one embodiment, the connecting component 22 includes 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 body 21 is detachably connected to the connecting groove; the locking member 222 is connected to the end of the fixing member 221 along the first direction, and the locking member 222 protrudes from the board body 21; the locking member 222 is provided with a locking groove 2221 on one side along the first direction; a locking buckle 13 is provided in the mounting groove 11, and the locking buckle 13 is rotatably connected to the box body 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 to the box body 1 through the torsion spring, when the board card device 2 slides along the second direction into the installation groove 11, the fixing piece 221 contacts the locking buckle 13 and pushes it to rotate to the unlocking position, avoiding the installation path of the board card device 2, thereby ensuring that the installation process of the board card device 2 is not hindered in any way; when the board card device 2 is installed in place, the locking buckle 13 and the locking groove 2221 are in corresponding positions to each other, and the locking buckle 13 is driven to rotate in the opposite direction under the elastic force of the torsion spring until it is completely embedded in the locking groove 2221, thereby fixing 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 implementation, the locking groove 2221 is an arc groove.

[0067] Preferably, an arc-shaped slideway is provided on the side wall of the installation groove 11, and the arc-shaped slideway is Figure 2 The arc-shaped profile of the locking groove 2221 shown matches, and a protruding stop block is provided at one end of the locking member 222 away from the torsion spring. The stop block is located on the side where the arc-shaped slideway is located, and is slidably arranged in the arc-shaped slideway. The rotation angle of the locking buckle 13 is limited by the arrangement of the arc-shaped slideway and the stop block, which effectively avoids the risk of unexpected loosening or deviation of the locking buckle 13 from the predetermined locking position after reaching the locked state, thereby greatly improving the stability and operational reliability of the board and card device 2 after the installation operation is completed. The limiting effect of the arc-shaped slideway and the stop block not only enhances the locking effect of the locking buckle 13, but also ensures the tight connection between the board and card device 2 and the box body 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 by observing the sliding position of the limit block in the arc slide, it is possible to visually judge whether the board card device 2 has been correctly installed. Figure 2 Rotate the limit block counterclockwise as shown until the locking buckle 13 reaches the unlocked state (as shown in FIG. Figure 2 As shown), the board device 2 can be disassembled at this time.

[0069] In a specific embodiment, in a natural state, the locking buckle 13 is in a locked position under the action of the torsion spring. Figure 2 It is a schematic structural diagram showing that the board clamp device 2 is installed in place, and the locking buckle 13 has not yet 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 arranged at two ends of the fixing member 221 along the first direction, and 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 body 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 correspondingly installed in a corresponding installation slot 11.

[0072] Specifically, a partition is provided between two adjacent installation grooves 11. The provision of the partition can not only divide the interior of the box body 1 into a plurality of independent installation grooves 11, but also can serve as a thermal isolation barrier to reduce the mutual influence of adjacent board devices 2 when generating heat, thereby ensuring that the heat generated by the board device 2 with a higher heating temperature is effectively isolated, thereby avoiding its adverse effect on the surrounding board devices 2 with a lower heating temperature.

[0073] Specifically, the partition structure 12 is provided with a plurality of communication ports, the plurality of communication ports correspond one-to-one to the plurality of mounting slots 11, and a group of fan structures 32 and a group of power components are correspondingly arranged at each communication port.

[0074] In one embodiment, a conductive contact 2211 is disposed in the connection slot; a conductive contact piece is disposed at one end of the board body 21 along the second direction, and the conductive contact piece is plug-connected to the connection slot and electrically connected to the conductive contact 2211 .

[0075] By providing the conductive contact 2211 and the conductive contact sheet, an electrical connection between the board body 21 and the fixing member 221 is achieved, which helps to achieve the connection between the board body 21 and the system.

[0076] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
