Description

Technical Field

[0001] This application relates to the field of computer technology, specifically to chassis and electronic equipment. Background Technology

[0002] Typical server racks are standard 19-inch (equipment mounting rails are 19 inches wide) rack-mount structures, suitable for most servers, switches, routers and other communication equipment.

[0003] In related technologies, quick-plug servers include rack-mount chassis and electronic modules installed within the chassis. A plug connector is located on one side of the chassis, and a door panel is rotatably connected to the other side. Multiple electronic modules are installed inside the chassis and secured by a clamping device within the chassis. Before opening or closing the door panel, the clamping device needs to be operated separately to press and secure the electronic modules, which is rather cumbersome.

[0004] The chassis in the related technology cannot achieve the cooperation between the clamping device and the door panel, so that the clamping device can automatically clamp and fix the electronic module after the door panel is closed. Summary of the Invention

[0005] In view of this, this application provides a chassis and electronic equipment to solve or improve the problem that the clamping device cannot automatically clamp the electronic module after the door panel is closed.

[0006] In a first aspect, this application provides a chassis, comprising:

[0007] The box has a door panel that rotates through an opening on one side;

[0008] Multiple cavities are spaced apart along a first direction on the inner side plate of the housing. Each cavity is provided with a first through hole and a second through hole. The axial direction of the first through hole is parallel to the first direction, and the axial direction of the second through hole intersects the first direction. A pressure transmission medium is provided inside the cavity.

[0009] The extrusion frame is provided with multiple filling blocks, and the multiple filling blocks are slidably and sealingly connected to multiple first through holes. One end of the extrusion frame can slide against the door panel.

[0010] Multiple compression blocks are slidably and sealingly connected to multiple second through holes, and the compression blocks are adapted to press the electronic module into the housing.

[0011] In this embodiment, the electronic module is placed into the housing through the opening. The door panel is rotated, and before the opening is completely closed, the door panel can abut against the extrusion frame. The extrusion frame is slidably connected to the housing along the first direction. As the door panel is completely closed, the door panel and the extrusion frame slide against each other, and the door panel drives the extrusion frame to move along the first direction. At the same time, the filling block on the extrusion frame passes through the corresponding first through hole. Before the filling block completely enters the cavity from the first through hole, the pressure of the pressure transmission medium in the cavity is the initial pressure. The filling block enters the cavity, compresses the volume of the pressure transmission medium in the cavity, thereby increasing the pressure of the pressure transmission medium. The increased pressure acts on the extrusion block, and the extrusion block extends out of the cavity along the axial direction of the second through hole and is suitable for pressing against the electronic module, thereby fixing the electronic module at multiple points to solve or improve the problem that the electronic module cannot be automatically pressed after the door panel is closed.

[0032] Typical server racks are standard 19-inch rack-mount structures (equipment mounting rails are 19 inches wide), suitable for the vast majority of servers, switches, routers and other communication equipment.

[0033] In related technologies, quick-plug servers include rack-mount chassis and electronic modules installed within the chassis. A plug connector is located on one side of the chassis, and a door panel is rotatably connected to the other side. Multiple electronic modules are installed inside the chassis and secured by a clamping device within the chassis. Before opening or closing the door panel, the clamping device needs to be operated separately to press and secure the electronic modules, which is rather cumbersome.

[0034] In related technologies, the chassis cannot achieve a proper fit between the clamping device and the door panel, allowing the clamping device to automatically clamp and secure the electronic modules when the door panel is closed. Therefore, this application provides a chassis and electronic equipment to solve or improve the problem of not being able to effectively secure multiple electronic modules at multiple points.

[0035] The following is combined with Figures 1 to 14 This describes an embodiment of the present application.

[0036] According to an embodiment of this application, in one aspect, a chassis is provided, including: a chassis 1, a plurality of cavities 3, an extrusion frame 5, and a plurality of extrusion blocks 7.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the housing 1 has a door panel 2 rotatably mounted on an opening on one side; multiple cavities 3 are spaced apart along a first direction X on the inner side plate of the housing 1, each cavity 3 having a first through hole 301 and a second through hole, the axis of the first through hole 301 being parallel to the first direction X, and the axis of the second through hole intersecting the first direction X, and a pressure transmission medium is provided inside the cavity 3; the extrusion frame 5 is provided with multiple filling blocks 6, the multiple filling blocks 6 being slidably sealed to the multiple first through holes 301, and one end of the extrusion frame 5 being able to slide against the door panel 2; multiple extrusion blocks 7 are slidably sealed to the multiple second through holes one-to-one, and the extrusion blocks 7 are suitable for pressing the electronic module 10 into the housing 1.

[0038] In this embodiment, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, an opening is provided on one side of the housing 1. The electronic module 10 is placed into the housing 1 through the opening. The door panel 2 is rotated. Before the opening is completely closed, the door panel 2 can abut against the extrusion frame 5. The extrusion frame 5 is slidably connected to the housing 1 along the first direction X. As the door panel 2 is completely closed, the door panel 2 and the extrusion frame 5 slide against each other. The door panel 2 drives the extrusion frame 5 to move along the first direction X, that is, along the depth direction of the housing 1. Simultaneously, the filling block 6 on the extrusion frame 5 is inserted into the corresponding first through hole 301. Before the filling block 6 is fully inserted into the cavity 3 from the first through hole 301, the pressure of the pressure transmission medium in the cavity 3 is the initial pressure. The filling block 6 is inserted into the cavity 3, compressing the volume of the pressure transmission medium in the cavity 3, thereby increasing the pressure of the pressure transmission medium. The increased pressure acts on the extrusion block 7. The extrusion block 7 extends out of the cavity 3 along the axial direction of the second through hole and is suitable for pressing on the electronic module 10, thereby fixing the electronic module 10 at multiple points to solve or improve the problem that the electronic module 10 cannot be automatically pressed after the door panel 2 is closed.

[0039] Specifically, the axial direction of the second through hole is perpendicular to the first direction X.

[0040] In one embodiment, along the first direction X, each cavity 3 has a first through hole 301 on its opposite side walls, and each cavity 3 has an elastic tube 4. The two ends of the elastic tube 4 are sealed and connected to the corresponding two first through holes 301. The extrusion frame 5 slides through multiple elastic tubes 4 in sequence along the first direction X, and multiple filling blocks 6 can be inserted into the corresponding elastic tubes 4.

[0041] like Figure 1 , Figure 5 and Figure 8 As shown, multiple cavities 3 are arranged at intervals along the first direction X. A compression frame 5 slides sequentially through multiple elastic tubes 4 along the first direction X. Multiple filling blocks 6 suitable for penetrating into the elastic tubes 4 are provided on the compression frame 5. Multiple filling blocks 6 can simultaneously penetrate their corresponding elastic tubes 4. A receiving space is formed between the outer wall of the elastic tube 4 and the inner wall of the cavity 3. A pressure transmission medium is provided within the receiving space. The pressure transmission medium fills the receiving space. Before the filling block 6 enters the elastic tube 4, the elastic tube 4 is compressed under the pressure of the pressure transmission medium. As the door panel 2 closes, multiple... The filling block 6 is inserted into the corresponding elastic tube 4 at the same time. The volume of the elastic tube 4 increases, which in turn squeezes the pressure transmission medium in the cavity 3, thereby increasing the pressure of the pressure transmission medium on the squeezing block 7. Under the pressure of the pressure transmission medium, the squeezing block 7 extends out of the cavity 3 along the axial direction of the second through hole and presses the squeezing block 7 onto the electronic module 10. The axial direction of the second through hole is parallel to the width direction of the housing 1. Multiple squeezing blocks 7 fix the electronic module 10 at multiple points. Moreover, the number of cavities 3 is large and the volume is small, which is suitable for the current dense installation of electronic modules 10.

[0042] In some embodiments, such as Figure 8 As shown, the filler block 6 has an inclined surface at one end near the first through hole 301 along the first direction X, which facilitates the filling block 6 to pass through the elastic tube 4.

[0043] In some embodiments, such as Figure 11 As shown, multiple cavities 3 are arranged inside the housing 1 and located on both sides of its width. Multiple cavities 3 on the left side are connected to an extrusion frame 5, and multiple cavities 3 on the right side are connected to an extrusion frame 5. The second through holes opened on the left and right cavities 3 are arranged opposite to each other. Rotating the door panel 2 can simultaneously drive the extrusion frames 5 on both sides to move along the first direction X.

[0044] In some embodiments, such as Figure 2 and Figure 8 As shown, it also includes a guide member 504, which is fixed to the inner wall of the housing 1. The guide member 504 has a first guide hole, the axis of which is parallel to the first direction X. The extrusion frame 5 is slidably connected to the first guide hole.

[0045] In some embodiments, such as Figure 8As shown, the extrusion frame 5 includes a connecting rod 502 and multiple connecting plates 501. Two adjacent filling blocks 6 are connected by connecting plates 501. The connecting plates 501 can pass through the elastic tube 4. The surface of the connecting plate 501 is provided with a sliding hole 5011. The extension direction of the sliding hole 5011 is parallel to the first direction X. The inner wall of the box 1 is provided with a connecting block 503. The connecting block 503 is slidably connected to the sliding hole 5011 to support the connecting plate 501 and guide the connecting plate 501. The connecting rod 502 is slidably connected to the first guide hole.

[0046] Specifically, such as Figure 7 and Figure 8 As shown, each cavity 3 is provided with two first through holes 301 on one side along the first direction X. The two first through holes 301 are arranged at intervals along the height direction of the cavity 3, that is, at intervals along the second direction Z. The height direction of the cavity 3 is parallel to the height direction of the box 1. Multiple connecting plates 501 form two rows, each row corresponding to a set of first through holes 301 along the first direction X. The connecting block 503 is a U-shaped frame. The two side plates of the U-shaped frame are slidably connected to the sliding holes 5011 of the upper and lower rows of connecting plates 501 respectively. The connecting rod 502 is bent to form a U-shaped rod. The U-shaped rod is connected to the two filling blocks 6 at the head end of the extrusion frame 5.

[0047] In some embodiments, the pressure transmission medium is water or an incompressible liquid, or it may be a gas, or it may be a flowing substance, such as sand or particles.

[0048] In some embodiments, such as Figure 1 As shown, a handle 21 is provided on the door panel 2.

[0049] In some embodiments, such as Figure 5 As shown, it also includes a sealing member 14 with a cavity. The sealing member 14 has a first connecting hole and a second connecting hole. The sealing member 14 is disposed in the cavity 3, and the first connecting hole corresponds to the second through hole. The edge of the first connecting hole is sealed to the edge of the second through hole, and the edge of the second connecting hole is sealed to the periphery of the extrusion block 7.

[0050] In this embodiment, such as Figure 5 As shown, the first connecting hole of the seal 14 is sealed to the edge of the second through hole, and the second connecting hole is sealed to the periphery of the extrusion block 7, which can prevent the pressure transmission medium in the cavity 3 from leaking out from the second through hole and improve the sealing effect of the second through hole.

[0051] In one implementation, such as Figure 5 and Figure 6As shown, it also includes at least one thermal expansion block 11. The inner wall of the extrusion block 7 corresponding to the second through hole is provided with an installation groove. The thermal expansion block 11 is installed in the installation groove. When the thermal expansion block 11 reaches the threshold temperature, it can extend out of the groove and abut against the outer wall of the cavity 3.

[0052] In this embodiment, after the door panel 2 is closed, the extrusion block 7 extends out of the second through hole under the pressure of the pressure transmission medium and extrudes into the electronic module 10. The thermal expansion block 11 extends out of the second through hole along with the extrusion block 7 and expands along the first direction X. After the electronic module 10 has been working for a period of time, its temperature rises. After the temperature of the thermal expansion block 11 reaches the threshold temperature, it expands, extends out of the mounting groove, and abuts against the outer wall of the cavity 3. When the door panel 2 is opened, under the pressure of the pressure transmission medium, or when the operator pulls the extrusion frame 5, the filling block 6 is pulled out from the elastic tube 4. The pressure inside the cavity 3 decreases, and the extrusion block 7 tends to retract into the cavity 3. However, the thermal expansion block 11 abuts against the outer wall of the cavity 3, so that the extrusion block 7 continues to extrude into the electronic module 10, preventing the operator from removing the electronic module 10 before its temperature drops below the threshold temperature and burning the operator. After opening the door panel 2, once the temperature of the electronic module 10 drops below the threshold temperature, the thermal expansion block 11 retracts into the mounting groove, and the compression block 7 retracts into the cavity 3, away from the electronic module 10. At this time, the staff can remove the electronic module 10 from the box 1 for replacement or repair.

[0053] In some embodiments, such as Figure 5 As shown, the extrusion block 7 is provided with two mounting slots, which are located on opposite sides of the extrusion block 7, and two thermal expansion blocks 11 are respectively located in the two mounting slots.

[0054] Specifically, the volume of the thermal expansion block 11 undergoes a normal transformation between 40°C and 70°C.

[0055] Specifically, the threshold temperature is 40℃.

[0056] Specifically, the thermal expansion block 11 is made of a thermal expansion polymer, which can be a low cross-linking rubber (such as silicone rubber, EPDM); or a thermoplastic (such as LDPE, HDPE).

[0057] Specifically, the thermal expansion block 11 can be made of shape memory alloy, depending on the actual situation. Shape memory alloy (such as Nitinol) is the first choice, and its expansion rate can reach 8%.

[0058] In one implementation, such as Figure 5 and Figure 6As shown, it also includes at least one hydraulic rod assembly 12, which is disposed in the cavity 3, and the piston rod of the hydraulic rod assembly 12 is connected to the extrusion block 7. The pressure transmission medium is adapted to enter and exit the liquid hole of the hydraulic rod assembly 12 to drive the piston rod of the hydraulic rod assembly 12 to extend and retract.

[0059] In this embodiment, such as Figure 5 and Figure 6 As shown, the pressure transmission medium enters and exits the hydraulic rod assembly 12 through the liquid hole to control the extension and retraction of the piston rod. When the filling block 6 enters the elastic tube 4, the volume of the elastic tube 4 increases, compressing the pressure transmission medium in the cavity 3. The pressure transmission medium enters the hydraulic rod assembly 12 through the liquid hole, pushing its piston rod to extend. The piston rod pushes the extrusion block 7 out of the cavity 3.

[0060] In some embodiments, the hydraulic rod assembly 12 includes a first cylinder, a first piston, and a first piston rod. The first piston is slidably connected to the first cylinder. One end of the first piston rod is connected to the first piston, and the other end is connected to the compression block 7. A rodless cavity is formed between the first piston and the first cylinder. A liquid hole is provided on the first cylinder, and the liquid hole communicates with the rodless cavity.

[0061] Specifically, the hydraulic rod assembly 12 can be a hydraulic telescopic rod from related technologies.

[0062] In one implementation, such as Figure 6 As shown, it also includes at least one first elastic component 13, which is disposed in the cavity 3. One end of the first elastic component 13 is connected to the inner wall of the cavity 3, and the other end is connected to the extrusion block 7. Under the elastic force of the first elastic component 13, the extrusion block 7 has a tendency to retract into the cavity 3.

[0063] In this embodiment, such as Figure 5 and Figure 6 As shown, when the door panel 2 is opened, the door panel 2 loses pressure on the extrusion frame 5. Under the pressure of the pressure transmission medium, the filling block 6 is extruded out of the elastic tube 4. Alternatively, the operator can pull the extrusion frame 5 to pull the filling block 6 out of the elastic tube 4. The pressure transmission medium loses pressure on the hydraulic rod assembly 12. At the same time, the first elastic component 13 applies a pulling force to the extrusion block 7, pulling the extrusion block 7 back into the cavity 3. This ensures that after the door panel 2 is opened, the extrusion block 7 loses its extrusion force on the electronic module 10, making it convenient for the operator to disassemble the electronic module 10.

[0064] Specifically, the first elastic component 13 may be a first spring or a spring-type telescopic rod in the related art.

[0065] In some embodiments, any number of first elastic components 13 may be provided according to actual needs.

[0066] In one implementation, such as Figure 5 As shown, the sealing element 14 is a flexible tube. One end of the flexible tube is sealed to the edge of the second through hole, and the other end is sealed to the periphery of the extrusion block 7 through the sealing ring 22.

[0067] In this embodiment, the length of the flexible tube can change with the movement of the extrusion block 7 without affecting the movement of the extrusion block 7.

[0068] In some embodiments, the flexible tube is a corrugated tube, the axial direction of which is the same as the direction of extension and retraction of the extrusion block 7, and the flexible tube is made of rubber.

[0069] In one implementation, such as Figure 1 , Figure 9 and Figure 11 As shown, it also includes multiple mounting components 8, which are spaced apart in the housing 1 along the second direction Z. Multiple receiving slots 15 are formed between the multiple mounting components 8 and the housing 1. The opening of each receiving slot 15 is parallel to the first direction X. Multiple cavities 3 are provided in each receiving slot 15. The second direction Z is the height direction of the housing 1.

[0070] In this embodiment, such as Figure 1 , Figure 9 and Figure 11 As shown, the staff installs the electronic module 10 from the slot into the receiving slot 15. Each receiving slot 15 contains an electronic module 10. The receiving slot 15 has multiple cavities 3. The pressing blocks 7 on the multiple cavities 3 press against the electronic module 10, fixing the electronic module 10 in the receiving slot 15. This multi-point fixation of the electronic module 10 improves the fixing effect.

[0071] In some embodiments, such as Figure 1 , Figure 9 and Figure 11 As shown, multiple cavities 3 are provided on both sides of the receiving groove 15. After the door panel 2 is closed, the pressing blocks 7 on both sides of the cavity 3 simultaneously pressurize the electronic module 10, thereby achieving multi-point fixation of the electronic module 10.

[0072] In one implementation, such as Figure 9 , Figure 10 and Figure 11 As shown, the mounting assembly 8 includes a groove 801 and a mounting bracket 802. Specifically, the groove 801 is connected to the housing 1 and extends through the groove 801 along the first direction X. The mounting bracket 802 is disposed inside the groove 801 and has a first gap 16 between it and the bottom plate of the groove 801. Multiple rollers 803 are rotatably disposed on the mounting bracket 802 and are adapted to roll against the bottom of the electronic module 10.

[0073] In this embodiment, such as Figure 9 , Figure 10 and Figure 11 As shown, the slots 801 are spaced apart in the housing 1 along the second direction Z, and the mounting brackets 802 are disposed in the slots 801. The mounting brackets 802 are provided with rollers 803. When installing or removing the electronic module 10, the rollers 803 roll against the bottom of the electronic module 10, making installation or removal easier and reducing wear on the bottom of the electronic module 10 during installation or removal. A first gap 16 is provided between the mounting brackets 802 and the bottom plate of the slots 801, which can improve the heat dissipation effect of the electronic module 10.

[0074] In one implementation, such as Figure 3 , Figure 10 and Figure 11 As shown, the tank 801 has a receiving cavity 8011 inside its wall. The receiving cavity 8011 is connected to a plurality of corresponding cavities 3. The receiving cavity 8011 contains a pressure transmission medium. The bottom plate of the tank 801 is elastic. The mounting bracket 802 has a second gap 24. The bottom plate of the tank 801 expands under the action of the pressure transmission medium and can pass through the second gap 24 to abut against the bottom of the electronic module 10.

[0075] In this embodiment, such as Figure 3 , Figure 10 and Figure 11 As shown, multiple cavities 3 within a receiving groove 15 are connected to corresponding receiving cavities 8011. Receiving cavities 8011 are filled with a pressure transmission medium. When the door panel 2 is closed, multiple filling blocks 6 simultaneously penetrate into corresponding elastic tubes 4, increasing the volume of the elastic tubes 4 and increasing the pressure of the pressure transmission medium within the cavities 3. The pressure within the receiving cavities 8011 is the same as the pressure within the cavities 3, causing the bottom plate of the groove 801 to expand. Part of the bottom plate of the groove 801 passes through the second gap 24 and abuts against the bottom of the electronic module 10, with pressure between them. This further secures the electronic module 10, improving the stability of the electronic module 10 installed within the housing 1. Simultaneously, the pressure transmission medium, by abutting against the bottom of the electronic module 10, carries away the heat from the electronic module 10, improving its heat dissipation effect.

[0076] In some embodiments, such as Figure 2 and Figure 7 As shown, the cavity 3 has an outlet, and the tank 801 has an inlet that connects to the receiving cavity 8011. The outlet and the inlet are connected by the infusion pipe 23.

[0077] Specifically, such as Figure 10 As shown, the bottom plate of the tank 801 is a rubber sheet 804.

[0078] In one implementation, such as Figure 11As shown, the mounting bracket 802 includes: multiple support rods 8021, all of which extend along a third direction Y and are connected at both ends to the side wall of the groove 801. The multiple support rods 8021 are arranged at intervals along a first direction X, and the gap between two adjacent support rods 8021 is a second gap 24. Multiple rollers 803 are rotatably connected to the multiple support rods 8021.

[0079] In this embodiment, such as Figure 9 As shown, multiple support rods 8021 are connected to the groove 801, and multiple rollers 803 are rotatably connected to each support rod 8021. The tops of the multiple rollers 803 along the second direction Z are on the same plane, ensuring that each roller 803 is in contact with the bottom of the electronic module 10.

[0080] In one embodiment, a heat dissipation component 9 is also included, disposed on the housing 1, for dissipating heat from the electronic module 10.

[0081] In this embodiment, the heat dissipation effect on the electronic module 10 is further improved.

[0082] In one implementation, such as Figure 1 , Figure 12 and Figure 13 As shown, the heat dissipation assembly 9 includes at least one air duct 901 and at least one heat-conducting plate 903. Specifically, at least one air duct 901 is disposed on the outer wall of the housing 1. One end of the air duct 901 is adapted to connect to an air supply device, and the other end is provided with an exhaust valve 902. At least one fourth through hole is opened on the side wall of the air duct 901. The housing 1 is provided with a first through hole corresponding to the fourth through hole, and the groove 801 is provided with a first through hole corresponding to the first through hole. The first through hole communicates with the receiving cavity 8011. The heat-conducting plate 903 passes through the fourth through hole, the first through hole, and the first through hole in sequence.

[0083] In this embodiment, such as Figure 1 , Figure 12 and Figure 13 As shown, the gas supply device provides gas into the gas supply pipe 901. An exhaust valve 902 is provided at the other end of the gas supply pipe 901. When the gas pressure in the gas supply pipe 901 reaches the rated gas pressure, the exhaust valve 902 automatically opens. The heat-conducting plate 903 passes through the fourth through hole, the first through hole, and the first through hole in sequence. Part of the heat-conducting plate 903 is set in the gas supply pipe 901, and part of it is set in the receiving cavity 8011 and contacts the pressure transmission medium. The pressure transmission medium exchanges heat with the electronic module 10 through the bottom plate of the tank 801. The heat-conducting plate 903 transfers the heat of the pressure transmission medium to the gas supply pipe 901. When the exhaust valve 902 opens, the heat on the heat sink is discharged.

[0084] In some embodiments, such as Figure 1As shown, multiple air guide pipes 901 are provided, with air guide pipes 901 on both sides of each tank 801.

[0085] In some embodiments, such as Figure 12 and 13 As shown, multiple heat-conducting plates 903 are provided, and multiple heat-conducting plates 903 are provided in each air duct 901.

[0086] In one implementation, such as Figure 10 , Figure 12 and Figure 13 As shown, the heat dissipation assembly 9 further includes: at least one baffle 904, at least one pneumatic rod assembly 905, and at least one second elastic component 906. Specifically, at least one baffle 904 is disposed within the receiving cavity 8011, and the baffle 904 is provided with a guide groove, which is slidably connected to the heat-conducting plate 903; at least one pneumatic rod assembly 905 is disposed within the air guide pipe 901, and the piston rod of the pneumatic rod assembly 905 passes through the housing 1 and the groove 801 and is connected to the baffle 904, allowing gas in the air guide pipe 901 to enter and exit the air holes of the pneumatic rod assembly 905 to drive the piston rod of the pneumatic rod assembly 905 to extend and retract; at least one second elastic component 906 is disposed within the receiving cavity 8011, with one end of the second elastic component 906 connected to the baffle 904 and the other end connected to the groove 801, and under the elastic force of the second elastic component 906, the baffle 904 tends to move towards the air guide pipe 901 along the third direction Y.

[0087] In this embodiment, such as Figure 10 , Figure 12 and Figure 13 As shown, when the air pressure in the air duct 901 increases but has not yet reached the rated air pressure, the gas enters the air pressure rod assembly 905 through the air hole, driving the piston rod of the air pressure rod assembly 905 to extend and push the baffle 904 to move away from the air duct 901 in the third direction Y. During this process, the guide groove of the baffle 904 is slidably connected to the heat conduction plate 903, which can limit the movement direction of the baffle 904, so that the plate surface of the baffle 904 is perpendicular to its movement direction, increasing the contact area with the pressure transmission medium in its movement direction. When the air pressure inside the heat pipe reaches the rated air pressure, the exhaust valve 902 opens. The rated air pressure is adjustable from 0.3 MPa to 0.7 MPa, and the gas in the air pipe 901 is discharged. As the air pressure in the air pipe 901 decreases, the piston rod of the air pressure rod assembly 905 retracts, and the second elastic component pushes the baffle 904 toward the air pipe 901. The baffle 904 moves within the receiving cavity 8011 and agitates the pressure transmission medium within the receiving cavity 8011, making the temperature of the pressure transmission medium within the receiving cavity 8011 more uniform and further improving the heat dissipation effect on the electronic module 10.

[0088] In some embodiments, such as Figure 10 and Figure 14 As shown, the heat dissipation assembly 9 also includes at least one pipe 909, one end of which is sealed. The side wall of the air duct 901 is provided with at least one third through hole. The housing 1 is provided with at least one second through hole corresponding to the third through hole. The slot 801 is provided with at least one second through hole and at least one third through hole 8012 corresponding to the second through hole. The open end of the pipe 909 passes through the third through hole, the second through hole, the second through hole and the third through hole 8012 in sequence. The open end of the pipe 909 is connected to the first gap 16. A water absorption component 910 is provided inside the pipe 909. The water absorption component 910 is provided at the open end of the pipe 909.

[0089] Specifically, the absorbent component 910 is an absorbent sponge or a desiccant such as quicklime or calcium chloride.

[0090] In some embodiments, such as Figure 13 As shown, the pipe fitting 909 extends along the third direction Y, and the spoiler 904 has a second guide hole, which is slidably connected to the pipe fitting 909.

[0091] In some embodiments, fitting 909 is a square tube.

[0092] In some embodiments, such as Figure 12 and Figure 14 As shown, the pipe fitting 909 is configured along its length as a fixed section 9091, a venting section 9092, and a guide section 9093. The pipe wall of the air guide pipe 901 is provided with a fixing hole, and the fixed section 9091 is fixed in the fixing hole. The venting section 9092 is disposed in the air guide pipe 901 and includes two branch pipes 90921. The two branch pipes 90921 are respectively connected to the fixed section 9091 and the guide section 9093, and there is a third gap 20 between the two branch pipes 90921 to facilitate the passage of gas in the air guide pipe 901. The guide section 9093 is disposed in the receiving cavity 8011.

[0093] In some embodiments, such as Figure 10 and 12 and Figure 13 As shown, both the pneumatic rod assembly 905 and the second elastic assembly 906 are configured in multiple ways.

[0094] In some embodiments, such as Figure 10 and Figure 13 As shown, the second elastic component 906 includes a second spring 9061 and a fixing plate 9062. The fixing plate 9062 is disposed in the receiving cavity 8011 and fixed on the cavity wall of the receiving cavity 8011. The two ends of the second spring 9061 are respectively connected to the spoiler 904 and the fixing plate 9062.

[0095] Specifically, the pneumatic rod assembly 905 includes a second cylinder, a second piston, and a second piston rod. The second piston is slidably connected to the second cylinder. One end of the second piston rod is connected to the second piston, and the other end is connected to the spoiler 904. A rodless chamber is formed between the second piston and the second cylinder. An air hole is provided on the second cylinder, and the air hole communicates with the rodless chamber.

[0096] Specifically, the pneumatic rod assembly 905 can be a pneumatic telescopic rod from related technologies.

[0097] In one implementation, such as Figure 1 As shown, the heat dissipation assembly 9 also includes an air pump 907 and a connecting pipe 908. Specifically, the air pump 907 is installed on the housing 1; one end of the connecting pipe 908 is sealed, and the other end is connected to the air pump 907. Multiple air outlets are provided on the connecting pipe 908; the heat dissipation assembly 9 is provided with multiple air guide pipes 901, and the end of the multiple air guide pipes 901 away from the exhaust valve 902 is connected to the multiple air outlets one by one.

[0098] In this embodiment, such as Figure 1 As shown, each tank 801 has an air guide pipe 901 on both sides. The connecting pipe 908 is a U-shaped pipe. One end of the U-shaped pipe is connected to the air pump 907, and the other end is sealed. The U-shaped pipe is provided with multiple air outlets, which are connected to multiple air guide pipes 901 one by one. The U-shaped pipe is connected to multiple air guide pipes 901 at the same time.

[0099] On the other hand, an electronic device, such as Figure 1 , Figure 3 and Figure 4 As shown, it includes:

[0100] The chassis, the back panel of the enclosure 1 is provided with a quick-connect connector 17 and a quick-connect connector 18 for electrical connection;

[0101] The electronic module 10 is provided with a connecting groove 19 corresponding to the extrusion block 7. The extrusion block 7 can be inserted into the connecting groove 19 to restrict the movement of the electronic module 10 along the first direction X. The quick-connect connector 17 can be electrically connected to the electronic module 10.

[0102] In this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, an opening is provided on one side of the housing 1. The electronic module 10 is placed into the housing 1 through the opening. The door panel 2 is rotated, and before the opening is completely closed, the door panel 2 can abut against the extrusion frame 5. As the door panel 2 is completely closed, the door panel 2 slides against the extrusion frame 5, and the door panel 2 drives the extrusion frame 5 to move along the first direction X. The extrusion frame 5 slides along the first direction X and passes through multiple elastic tubes 4 in sequence. Multiple filling blocks 6 can simultaneously enter their corresponding elastic tubes 4. Before the filling block 6 enters the elastic tube 4, the elastic tube 4 is compressed under the pressure of the pressure transmission medium. As the door panel 2 closes, multiple filling blocks 6 simultaneously enter their corresponding elastic tubes. Inside the tube 4, the volume of the elastic tube 4 increases, increasing the pressure of the pressure transmission medium in the cavity 3. The pressure transmission medium enters the rodless cavity of the hydraulic rod assembly 12 from the liquid hole, pushing its piston rod to extend. The piston rod pushes the extrusion block 7 to extend out of the cavity 3 along the axial direction of the second through hole. The extrusion block 7 is inserted into the connecting groove 19 and presses against the bottom of the connecting groove 19. An installation groove is opened on the side of the extrusion block 7. A thermal expansion block 11 is provided in the installation groove. After the electronic module 10 has been working for a period of time, the temperature rises. After the temperature of the thermal expansion block 11 reaches the threshold temperature, it expands, extends out of the installation groove, and presses against the groove wall of the connecting groove 19. When the door panel 2 is opened, the door panel 2 loses pressure on the extrusion frame 5. Under the pressure of the pressure transmission medium, the filling block 6 is extruded out of the elastic tube 4. Alternatively, the operator can pull the extrusion frame 5 to pull the filling block 6 out of the elastic tube 4. At the same time, the first elastic component 13 applies a pulling force to the extrusion block 7 to pull it back into the cavity 3. However, the thermal expansion block 11 is pressed against the groove wall of the connecting groove 19, and the extrusion block 7 cannot retract into the cavity 3. This prevents the operator from removing the electronic module 10 before the temperature of the electronic module 10 drops below the threshold temperature, which could burn the operator.

[0103] Once the temperature of the electronic module 10 drops below the threshold temperature, the thermal expansion block 11 retracts into the mounting groove, moving away from the wall of the connecting groove 19. The extrusion block 7 retracts into the cavity 3, moving away from the electronic module 10. At this point, the staff can remove the electronic module 10 from the housing 1 for replacement or repair.

[0104] In some embodiments, the driving force Fhyd of the hydraulic rod assembly 12 and the pressure transmission medium satisfy the following functional relationship:

[0105] Fhyd = ΔP × Apiston; where ΔP is the pressure increment of the pressure transmission medium, and Apiston is the piston cross-sectional area of ​​the hydraulic rod assembly 12.

[0106] ΔP = pfill + (β / V0)ΔV, where pfill is the initial filling pressure of the pressure transmission medium, ΔV is the volume change of the elastic tube 4, β is the liquid compressibility modulus, and V0 is the initial volume of the pressure transmission medium.

[0107] Specifically, when pfill = 100000 Pa; V0 = 0.001 m 3 ΔV = 0.00002 m 3 β = 2.0 × 10 9 Pa; Apisin = 0.01 m 2 At this point, Fhyd = 401000N.

[0108] In some embodiments, the frictional force Ffric(T) between the thermal expansion block 11 and the connecting groove 19 varies with temperature as follows:

[0109] Ffric(T) = μ(T) × N(T); where μ(T) is the coefficient of friction at temperature T; and N(T) is the normal pressure generated by expansion at temperature T.

[0110] μ(T) = μ0 + α(T - T0), where T0 is the reference temperature (e.g., room temperature 25℃), μ0 is the friction coefficient at the reference temperature T0, α is the temperature coefficient, and T is the current operating temperature.

[0111] N(T) = kexp × (T - Tact), where Tact is the activation temperature threshold of thermal expansion block 11, and kexp is the coefficient of thermal expansion.

[0112] Specifically, when μ0=0.25; α=0.002; T0=25; kexp=120; Tact=40.

[0113] When T=30℃, Ffric=0.26×0=0N.

[0114] When T=45℃, Ffric=0.29×600=174N.

[0115] When T=70℃, Ffric=0.34×3600=1224N.

[0116] In some embodiments, the restoring force Fspring = kmur × (X0 + ΔX) provided by the spring-type telescopic rod is given by the spring force Fspring = kmur × (X0 + ΔX), where X0 is the initial length of the spring-type telescopic rod, ΔX is the deformation of the spring-type telescopic rod, and kmur is the stiffness coefficient of the spring-type telescopic rod.

[0117] Specifically, when kspring=500N / m, X0=0.02m, and ΔX=0.03m, Fspring=500×(0.02+0.03)=500×0.05=25N.

[0118] The system equilibrium condition (when the door is closed) is Fhyd + Ffric(T) ≥ Fspring + Fload, where Fload is the external load such as vibration of the electronic module 10.

[0119] The specific parameters mentioned above are only virtual parameters used for calculation and display. The actual parameters should be based on the specific parameters of the relevant parts in the application.

[0120] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
