Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, and in particular to a modular server heat dissipation structure and its usage method. Background Technology

[0002] A server is a high-performance computer system that provides data storage, computing, and resource sharing services to other devices on a network (such as computers and mobile phones). Server modularization is a new type of server architecture that breaks down computing, storage, and networking functions into independent modules that can be combined as needed, flexibly expanded, and uniformly managed.

[0003] A search revealed that patent CN220121208U proposes "a big data server with a protective device," which includes a shell, a groove, and a slider. The inner sidewalls at both ends of the shell are provided with grooves, and a slider is installed inside the grooves. A first support plate is installed at the end of the slider away from the groove, and the top of the first support plate is provided with the main body of the data server. By squeezing the piston rod through the first support plate, the hydraulic oil in the first hydraulic oil tank is pushed into the second hydraulic oil tank through the connecting pipe and squeezes the sealing plate and the main body of the first spring. Then, the deformation of the spring drives the sealing plate to push the hydraulic oil back into the first hydraulic oil tank, thereby improving the shock absorption effect of the main body of the data server.

[0004] The aforementioned patents have the following drawbacks: Servers operate under high load for extended periods, causing their internal core components, such as the CPU, power supply module, and hard drive, to continuously generate significant heat. A malfunctioning cooling system can lead to heat buildup and potentially a fire. Furthermore, aging wiring, short circuits, unstable external voltage causing electrical sparks, or static electricity from accumulated dust in the server room igniting surrounding insulation materials can all trigger server fires. Fires pose serious threats to equipment, data, personnel safety, and the server room itself. The aforementioned patents only improve vibration reduction and heat dissipation, failing to provide timely fire suppression in the event of a server fire. Therefore, there is an urgent need for a server structure that can simultaneously dissipate heat and extinguish fires, and can also disconnect power to the server before fire suppression. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the background art that accidental server fires cause serious damage to equipment, data, personnel safety, and computer rooms. The invention proposes a server structure that can extinguish fires while dissipating heat from the server, and can also cut off the power to the server before extinguishing the fire.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular server heat dissipation structure, comprising: a chassis and a server body, wherein the server body is installed at the bottom of the chassis cavity, and heat dissipation structures are provided on the top and side walls of the chassis cavity. The heat dissipation structures are used to dissipate heat from the server body. The heat dissipation structures are linked to a power-off structure and a fire extinguishing structure. The power-off structure cuts off power to the server body in the event of a fire, and the fire extinguishing structure is used to extinguish the fire. The heat dissipation structure is also linked to a separation structure, which, in the event of a fire, stops the heat dissipation structure and activates the power-off structure and the fire extinguishing structure. The heat dissipation structure includes a motor installed on the top of the chassis. The chassis has a support plate fixed inside, and a round rod is rotatably connected to the support plate. The bottom end of the round rod passes through the support plate and is fixed with a first blade. A groove is provided at the bottom of the first blade, and a slider is slidably connected inside the groove. A second blade is fixed at the bottom of the slider. The groove is connected to the slider by a fifth spring. The second blade is made of magnet. A slide plate is fixed to the side wall of the chassis, and a spoiler is slidably connected to the slide plate. The inner wall of the chassis is connected to the spoiler by a first spring. A magnetic rod extending towards the first blade is fixed to the spoiler. A temperature sensor is installed on the top of the chassis, and heat dissipation grooves are provided on the side wall of the chassis.

[0007] As a further embodiment of the present invention, the separation structure includes a circular sleeve slidably connected to the outside of a circular rod. A pad is fixed to the bottom of the circular rod, and a second spring is provided on the outside of the circular rod. The top end of the second spring is fixed to the bottom of the circular sleeve, and the bottom end of the second spring is fixed to the top of the pad. A circular pressure plate is fixed to the outside of the top end of the circular sleeve. A limiting plate made of fusible alloy is fixed to the top of the support plate. The circular sleeve passes through the limiting plate, and the pressure plate is located on top of the limiting plate. The second spring is in a stretched state. A slot is provided on the top of the circular sleeve, and a plug is fixed to the output end of the motor. The plug is inserted into the inside of the slot.

[0008] As a further embodiment of the present invention, the power-off structure includes a vertical rod fixed to the top of a support plate, a pressure block slidably connected to the outside of the vertical rod, a vertical plate fixed to the top of the support plate, a vertical groove provided on the vertical plate, a female connector slidably connected to the vertical plate along the vertical groove, a male connector fixed to the top of the female connector on the vertical plate, the plug of the male connector being inserted into the groove of the female connector, an extension plate fixed to the outside of the female connector, a power cord connected to the server body and the power cord being connected to the female connector, and another power cord connected to an external circuit being connected to the male connector.

[0009] As a further embodiment of the present invention, one end of the pressure block is located at the bottom of the pressure plate, and the other end of the pressure block is located directly above the extension plate.

[0010] As a further embodiment of the present invention, a cutter is fixed to one end of the pressure block, and a cutting groove that cooperates with the cutter is provided on the top of the support plate.

[0011] As a further embodiment of the present invention, the fire extinguishing structure includes a nitrogen tank fixed to the top of the chassis, a valve and an exhaust port installed at the bottom of the nitrogen tank, a gear fixed to the bottom of the valve stem, a horizontal plate fixed to the side of the support plate, a movable block slidably connected inside the horizontal plate and provided with a No. 3 spring, one end of the movable block being fixedly connected to the No. 3 spring, and a rack fixed to the movable block and meshing with the gear.

[0012] As a further embodiment of the present invention, the fire extinguishing structure also includes a horizontal groove on the side wall of the chassis located at the heat dissipation slot. A horizontal block is slidably connected inside the horizontal groove and a No. 4 spring is provided. One end of the No. 4 spring is fixedly connected to the horizontal block. A fireproof plate is fixed to the outside of the horizontal block, and a pull rope is fixed to the top protrusion of the support plate.

[0013] As a further embodiment of the present invention, a limit block is fixed at the top of the support plate, the pull rope passes through the limit block and through the third spring and the horizontal block and then exits from the bottom of the horizontal plate. After exiting the horizontal plate, the pull rope is divided into two strands and passes through the fourth spring and is fixedly connected to the horizontal block. The pull rope and the horizontal block are fixedly connected as a whole, and the third spring and the fourth spring are in a compressed state.

[0014] As a further embodiment of the present invention, the method of using the modular server heat dissipation is as follows: S1: When the server body is running normally, blade number one rotates at low speed. When the temperature sensor detects high temperature, it will increase the rotation speed of blade number one. At the same time, the increased rotation speed will increase the centrifugal force, causing blade number two to extend. Blade number two uses magnetic repulsion to drive the baffle to move and break the stratification of hot air, thus achieving efficient heat dissipation. S2: When high-temperature smoke appears inside the chassis before an open flame, the limit plate made of fusible alloy will melt, which will cause the plug to automatically detach from the slot, thus separating the connection between the motor and the round rod. Then the first blade will stop rotating to prevent the airflow from fueling the fire. S3: The above disconnection will forcibly separate the female and male connectors, quickly cutting off the power supply to the server body to prevent the fire from worsening. S4: When the power is cut off, the pull rope will be cut off, and then the compressed No. 3 and No. 4 springs will be reset. On the one hand, the nitrogen tank will release nitrogen to suffocate the flame, and on the other hand, the heat dissipation tank will be automatically closed to prevent external oxygen from entering and extinguishing the fire.

[0015] The modular server heat dissipation structure and its usage method proposed in this invention have the following advantages: 1. Through the set fire extinguishing structure, the pressure block descends, which also brings down the cutter. When the cutter descends, it enters the cutting groove and cuts the pull rope. Under normal conditions, the pull rope is taut, compressing the No. 3 and No. 4 springs. Therefore, when the pull rope is cut, the No. 3 and No. 4 springs will extend and return to their original state from the compressed state. The return of the No. 3 spring moves the movable block, which in turn moves the rack and pinion, causing the gear to rotate and open the valve. Then, the nitrogen in the nitrogen tank is discharged from the exhaust port to dilute the oxygen in the chassis, thereby extinguishing the fire in the chassis. In addition, the return of the No. 4 spring moves the horizontal block in the horizontal groove, and the movement of the horizontal block moves the fireproof plate to seal the heat sink, which helps to prevent outside air from entering the chassis and fueling the fire.

[0016] 2. Through the designed heat dissipation structure, under normal operating conditions, the motor drives the circular rod and the first blade to rotate through the connection between the plug and the circular sleeve for conventional heat dissipation. When the temperature inside the chassis rises to the high temperature threshold due to server load, the motor is controlled to speed up. The high-speed rotation of the first blade increases the centrifugal force on the second blade, causing it to extend and increase the sweeping area to enhance heat dissipation. At the same time, the rotating second blade repels the magnetic rod, forcing the spoiler to compress the first spring and then reset under the action of the first spring, generating continuous vibration and reciprocating motion, which in turn disturbs the gas inside the chassis, breaks up air stratification and dead zones, and greatly improves heat dissipation efficiency.

[0017] 3. Through the set power-off structure, the pressure plate descends and presses the pressure block, causing it to descend outside the vertical rod. When the pressure block descends, one end of it will press the extension plate, causing the female connector to descend along the vertical groove. Then, the female connector and the male connector separate, causing the server body to lose power. By quickly cutting off the power supply to the server body, the continuous power supply to the circuit is prevented from increasing the risk of fire or causing secondary failures.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0022] A modular server heat dissipation structure includes: a chassis 1 and a server body 2. The server body 2 is installed at the bottom of the inner cavity of the chassis 1. The top and side walls of the inner cavity of the chassis 1 are provided with heat dissipation structures for cooling the server body 2. The heat dissipation structure is linked to a power-off structure and a fire extinguishing structure. The power-off structure cuts off the power to the server body 2 in the event of a fire. The fire extinguishing structure is used for fire extinguishing. The heat dissipation structure is also linked to a separation structure. The separation structure stops the heat dissipation structure from working and activates the power-off structure and the fire extinguishing structure in the event of a fire.

[0023] Furthermore, the heat dissipation structure includes a motor 3 mounted on the top of the chassis 1, a support plate 4 fixed inside the chassis 1, a round rod 5 rotatably connected to the support plate 4, the bottom end of the round rod 5 passing through the support plate 4 and fixed with a first blade 6, a groove 7 provided at the bottom of the first blade 6, a slider 8 slidably connected inside the groove 7, a second blade 9 fixed at the bottom of the slider 8, a fifth spring 46 connecting the inside of the groove 7 to the slider 8, the second blade 9 being made of magnet, a sliding plate 10 fixed to the side wall of the chassis 1, a baffle 11 slidably connected to the sliding plate 10, a first spring 12 connecting the inner wall of the chassis 1 to the baffle 11, a magnetic rod 13 extending towards the first blade 6 fixed to the baffle 11, a temperature sensor 14 mounted on the top of the chassis 1, and heat dissipation grooves 15 provided on the side wall of the chassis 1.

[0024] It should be noted that in the non-extinguishing state, the plug 21 is located inside the slot 20, and the heat dissipation slot 15 is in the open state. The motor 3 starts and rotates the round rod 5 and the first blade 6. In this state, the centrifugal force on the second blade 9 is less than the resistance of the first spring 12, so the second blade 9 will not extend. This helps to prevent the second blade 9 from extending and increasing the load on the motor 3 under normal conditions. When the temperature inside the chassis 1 has not reached the high temperature threshold, the motor 3 rotates the first blade 6 normally (without speed adjustment) to dissipate heat from the server body 2, and works with the heat dissipation slot 15 to improve the heat dissipation effect. When the temperature inside the chassis 1 reaches the set high temperature threshold, the temperature sensor 14 senses the temperature inside the chassis 1 and converts it into an electrical signal. After receiving the signal, the controller directly controls the speed of the motor 3, thereby increasing the speed of the first blade 6 at high temperatures (this part of the speed adjustment is existing technology and will not be described in detail here). By adjusting the speed, the heat dissipation efficiency can be ensured at high temperatures to stabilize the server operation, and the energy consumption and noise of the motor 3 can be reduced at low temperatures.

[0025] As the rotational speed of blade 6 increases at high temperatures, the centrifugal force on blade 9 increases beyond the resistance exerted by spring 46. Therefore, when the rotational speed of blade 6 increases at high temperatures, blade 9 extends to increase the sweeping range of blade 6, thereby improving heat dissipation. When the rotational speed decreases, spring 46 returns to its original position, causing blade 9 to retract. Simultaneously, the extension and rotation of blade 9 acts on magnet rod 13. Since both blade 9 and magnet rod 13 are made of magnets and have the same pole design, the rotation of blade 9 is subject to magnetic repulsion. Under the action of the first spring 12, the spoiler 11 moves backward and presses against the first spring 12. When the second blade 9 leaves the magnet rod 13, the spoiler 11 returns to its original position under the action of the first spring 12. Through the reciprocating motion of the spoiler 11 and the vibration applied to the spoiler 11 by the first spring 12, the airflow inside the chassis 1 is disturbed by the spoiler 11, thereby breaking the airflow stratification inside the chassis 1, eliminating the heat dissipation dead zone, and allowing the airflow entering from the outside and the airflow blown out by the first blade 6 and the second blade 9 to fully contact the heat sink body 1, thereby greatly improving the heat dissipation efficiency.

[0026] Next, the separation structure includes a circular sleeve 16 slidably connected to the outside of the circular rod 5. A pad 19 is fixed to the bottom of the circular rod 5. A second spring 17 is provided on the outside of the circular rod 5. The top end of the second spring 17 is fixed to the bottom of the circular sleeve 16, and the bottom end of the second spring 17 is fixed to the top of the pad 19. A circular pressure plate 47 is fixed to the outside of the top of the circular sleeve 16. A fusible alloy limiting plate 18 is fixed to the top of the support plate 4. The circular sleeve 16 passes through the limiting plate 18, and the pressure plate 47 is located on top of the limiting plate 18. The second spring 17 is in a stretched state. A slot 20 is provided on the top of the circular sleeve 16. A plug 21 is fixed to the output end of the motor 3. The plug 21 is inserted into the inside of the slot 20.

[0027] It can be concluded that the limiting plate 18 is made of a fusible alloy and its melting point is lower than the temperature of the smoke when it is smoking but higher than the temperature of the chassis 1 at high temperature. Therefore, the limiting plate 18 will melt during the smoking stage but will not melt at high temperature inside the chassis 1. After the limiting plate 18 melts due to the fire and smoke, it loses its blocking force on the pressure plate 47. Therefore, the previously stretched second spring 17 will return to its original position and descend, thus sliding down outside the round rod 5 with the round sleeve 16 and the pressure plate 47. After the round sleeve 16 descends, the insert 21 leaves the inside of the slot 20. Then the motor 3 will only run idle and will not rotate the first blade 6, thereby preventing the airflow from increasing the fire. When the separation structure closes the heat dissipation structure, it is exactly when the power-off structure and the fire extinguishing structure are working.

[0028] The next step is to include a vertical rod 22 fixed to the top of the support plate 4, a pressure block 23 slidably connected to the outside of the vertical rod 22, a vertical plate 24 fixed to the top of the support plate 4, a vertical groove 25 provided on the vertical plate 24, a female connector 26 slidably connected to the vertical plate 24 along the vertical groove 25, a male connector 27 fixed to the top of the female connector 26 on the vertical plate 24, the plug of the male connector 27 being inserted into the groove of the female connector 26, an extension plate 28 fixed to the outside of the female connector 26, a power cord 45 connected to the server body 2 and the power cord 45 being connected to the female connector 26, another power cord 45 connected to an external circuit being connected to the male connector 27, one end of the pressure block 23 being located at the bottom of the pressure plate 47, the other end of the pressure block 23 being located directly above the extension plate 28, a cutter 29 fixed to one end of the pressure block 23, and a cutting groove 30 cooperating with the cutter 29 being provided on the top of the support plate 4.

[0029] Specifically, the pressure plate 47 descends and presses the pressure block 23, causing it to descend outside the vertical rod 22. When the pressure block 23 descends, one end of it presses the extension plate 28, causing the female connector 26 to descend along the vertical groove 25. Then, the female connector 26 separates from the male connector 27, causing the server body 2 to lose power. By quickly cutting off the power supply to the server body 2, the continuous power supply to the circuit is prevented from increasing the risk of fire or causing secondary failures.

[0030] Furthermore, the fire extinguishing structure includes a nitrogen tank 31 fixed to the top of the chassis 1. A valve 32 and an exhaust port 33 are installed at the bottom of the nitrogen tank 31. A gear 34 is fixed to the bottom of the valve stem of the valve 32. A horizontal plate 35 is fixed to the side of the support plate 4. A movable block 36 is slidably connected inside the horizontal plate 35 and a No. 3 spring 37 is provided. One end of the movable block 36 is fixedly connected to the No. 3 spring 37. A rack 38 is fixed to the movable block 36, and the rack 38 meshes with the gear 34. The fire extinguishing structure also includes a horizontal groove 39 located on the side wall of the chassis 1 at the heat dissipation slot 15. A horizontal block 40 is slidably connected inside the horizontal groove 39 and four... Spring 41, one end of which is fixedly connected to the horizontal block 40. A fireproof board 42 is fixed to the outside of the horizontal block 40. A pull rope 43 is fixed to the top protrusion of the support plate 4. The fireproof board 42 is made of a common material on the market. A limit block 44 is fixed to the top of the support plate 4. The pull rope 43 passes through the limit block 44, passes through the third spring 37 and the horizontal block 40, and then exits from the bottom of the horizontal plate 35. After exiting the horizontal plate 35, the pull rope 43 splits into two strands and passes through the fourth spring 41 before being fixedly connected to the horizontal block 40. The pull rope 43 and the horizontal block 40 are fixedly connected as a whole. The third spring 37 and the fourth spring 41 are in a compressed state.

[0031] Specifically, the descent of the pressure block 23 also causes the cutter 29 to descend. When the cutter 29 descends, it enters the cutting groove 30 and cuts the pull rope 43. Under normal conditions, the pull rope 43 is taut and compresses the No. 3 spring 37 and the No. 4 spring 41. Therefore, when the pull rope 43 is cut, the No. 3 spring 37 and the No. 4 spring 41 will extend and return to their original state from the compressed state. The return of the No. 3 spring 37 causes the movable block 36 to move. The movement of the movable block 36 causes the rack 38 to move and causes the gear 34 to rotate, opening the valve 32. Then, the nitrogen in the nitrogen tank 31 is discharged from the exhaust port 33 to dilute the oxygen in the chassis 1, thereby extinguishing the fire in the chassis 1. In addition, the return of the No. 4 spring 41 causes the horizontal block 40 to move in the horizontal groove 39. Then, the movement of the horizontal block 40 causes the fireproof plate 42 to move and seal the heat dissipation slot 15, which helps to prevent outside air from entering the chassis 1 and fueling the fire.

[0032] The following are methods for cooling servers: S1: When the server body 2 is running normally, the first blade 6 rotates at low speed. When the temperature sensor 14 detects high temperature, it will increase the speed of the first blade 6. At the same time, the centrifugal force increases after the speed increases, which will cause the second blade 9 to extend. The second blade 9 uses magnetic repulsion to drive the baffle 11 to move and break the hot air stratification, so as to achieve efficient heat dissipation. S2: When high-temperature smoke appears inside the chassis 1 before an open flame, the limit plate 18 made of fusible alloy will melt, which will cause the plug 21 to automatically separate from the slot 20, and the connection between the motor 3 and the round rod 5 will be separated. Then the first blade 6 will stop rotating to prevent the airflow from fueling the fire. S3: The above disconnection will forcibly separate the female connector 26 and the male connector 27, quickly cutting off the power supply to the server body 2 to prevent the fire from worsening. S4: When the power is cut off, the pull rope 43 will be cut off. Then the compressed No. 3 spring 37 and No. 4 spring 41 will be reset. On the one hand, the nitrogen tank 31 will release nitrogen to suffocate the flame, and on the other hand, the heat sink 15 will be automatically closed to prevent external oxygen from entering and extinguishing the fire.

[0033] Working principle: Through the heat dissipation structure, the plug 21 in the non-extinguishing state is located inside the slot 20, and the heat dissipation slot 15 is in the open state. The motor 3 starts and drives the round rod 5 and the first blade 6 to rotate. In this state, the centrifugal force on the second blade 9 is less than the resistance of the first spring 12, so the second blade 9 will not extend. This helps to prevent the second blade 9 from extending and increasing the load on the motor 3 under normal conditions. When the temperature inside the chassis 1 does not reach the high temperature threshold, the motor 3 drives the first blade 6 to rotate normally (without speed adjustment) to dissipate heat from the server body 2, and works with the heat dissipation slot 15 to improve the heat dissipation effect.

[0034] When the temperature inside the chassis 1 reaches the set high temperature threshold, the temperature sensor 14 senses the temperature inside the chassis 1 and converts it into an electrical signal. After receiving the signal, the controller directly controls the speed of the motor 3, thereby increasing the speed of the first blade 6 at high temperatures (this part of the speed adjustment is existing technology and will not be described in detail here). By adjusting the speed, heat dissipation efficiency can be ensured at high temperatures to stabilize server operation, and the energy consumption and noise of the motor 3 can be reduced at low temperatures.

[0035] As the rotational speed of blade 6 increases at high temperature, the centrifugal force on blade 9 increases to a greater extent than the resistance applied by spring 46. Therefore, when the rotational speed of blade 6 increases at high temperature, blade 9 will extend to increase the sweeping range of blade 6 and thus improve the heat dissipation effect. After the rotational speed decreases, spring 46 resets and takes blade 9 back.

[0036] At the same time, when the second blade 9 extends and rotates, it acts on the magnetic rod 13. Since both the second blade 9 and the magnetic rod 13 are made of magnets and have the same pole design, when the second blade 9 rotates, the deflector 11 moves back under the action of magnetic repulsion and presses the first spring 12. When the second blade 9 leaves the magnetic rod 13, the deflector 11 returns to its original position under the action of the first spring 12. Through the reciprocating motion of the deflector 11 and the vibration applied to the deflector 11 by the first spring 12, the airflow inside the chassis 1 is disturbed by the deflector 11, thereby breaking the airflow stratification inside the chassis 1, eliminating heat dissipation dead zones, and allowing the airflow entering from the outside and the airflow blown out by the first blade 6 and the second blade 9 to fully contact the heat sink body 1, thereby greatly improving the heat dissipation efficiency.

[0037] By setting up a separation structure, if blade 6 is still blowing air during a fire, the airflow will make the fire more intense. Therefore, when smoke appears (smoke will appear before flames are generated), blade 6 of the heat dissipation structure needs to stop working. The specific operation is as follows: the limit plate 18 is made of a fusible alloy and its melting point is lower than the temperature of the smoke when it appears but higher than the temperature of the chassis 1 at high temperature. So the limit plate 18 will melt during the smoke stage but will not melt at the high temperature inside the chassis 1. After the limit plate 18 melts due to the smoke from the fire, it loses its blocking force on the pressure plate 47. Therefore, the previously stretched spring 17 will return to its original position and descend, thus sliding the sleeve 16 and the pressure plate 47 downward outside the round rod 5. After the sleeve 16 descends, the insert 21 leaves the inside of the slot 20. Then the motor 3 will only run idle and will not rotate blade 6, thus preventing the airflow from increasing the fire. When the separation structure closes the heat dissipation structure, it is exactly when the power-off structure and the fire extinguishing structure are working.

[0038] By using the power-off structure, the descending pressure plate 47 presses down on the pressure block 23, causing it to descend outside the vertical rod 22. As the pressure block 23 descends, one end presses down on the extension plate 28, causing the female connector 26 to descend along the vertical groove 25. Then, the female connector 26 separates from the male connector 27, de-energizing the server body 2. This rapid power cut-off of the server body 2 prevents the circuit from continuously energizing, thus avoiding increased fire risk or secondary malfunctions. The separation of the heat dissipation structure, the de-energization of the server body 2, and the cutting of the pull rope 43 are all characteristic of this configuration. Figure 9 As shown.

[0039] The fire extinguishing structure allows the pressure block 23 to descend, which in turn causes the cutter 29 to descend as well. When the cutter 29 descends, it enters the cutting groove 30 and cuts the pull rope 43. Normally, the pull rope 43 is taut, compressing the No. 3 spring 37 and the No. 4 spring 41. Therefore, when the pull rope 43 is cut, the No. 3 spring 37 and the No. 4 spring 41 will extend and return to their original state from the compressed state. The return of the No. 3 spring 37 causes the movable block 36 to move. The movement of the movable block 36 causes the rack 38 to move, which in turn causes the gear 34 to rotate and open the valve 32. Then, the nitrogen in the nitrogen tank 31 is discharged from the exhaust port 33 to dilute the oxygen in the chassis 1, thereby extinguishing the fire in the chassis 1. In addition, the return of the No. 4 spring 41 causes the horizontal block 40 to move in the horizontal groove 39. Then, the movement of the horizontal block 40 causes the fireproof plate 42 to move and seal the heat dissipation slot 15, which helps to prevent outside air from entering the chassis 1 and fueling the fire.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

4. A method of using a modular server heat dissipation structure, characterized in that, The modular server heat dissipation structure is the modular server heat dissipation structure according to any one of claims 1-3, and the steps of using the heat dissipation structure are as follows: S1: When the server body (2) is running normally, the first blade (6) operates at low speed. When the temperature sensor (14) detects high temperature, it will increase the speed of the first blade (6). At the same time, the centrifugal force increases after the speed increases, which will cause the second blade (9) to extend. The second blade (9) uses magnetic repulsion to drive the baffle (11) to move and break the hot air stratification, so as to achieve efficient heat dissipation. S2: When high-temperature smoke before open flame appears inside the chassis (1), the limit plate (18) made of fusible alloy will melt, which will cause the plug (21) to automatically separate from the slot (20), so that the connection between the motor (3) and the round rod (5) is separated, and then the first blade (6) stops rotating to prevent the airflow from fueling the fire.
