Abstract
Description
Technical Field
[0001] This invention belongs to the field of data center cabinet heat dissipation technology, specifically a hot and cold aisle integrated cabinet with emergency air supply and exhaust modules and its application. Background Technology
[0002] In data center cabinets, to avoid the mixing of hot and cold air affecting the cooling effect, the cabinets are usually arranged in two rows with their doors facing each other. This creates a cold aisle between the two rows of cabinets, which is used to supply cold air. During use, the data center's air conditioning system delivers cold air into the cabinets through the cold aisle for cooling, while the hot air generated by the cabinets is exhausted from the hot aisle on the outside through a circulation system.
[0003] For example, invention application CN119584475A discloses a safe and reliable cold aisle for data center computer rooms in the field of data center heat dissipation and cooling device technology. The cold aisle includes a base plate component, a frame component, a data center cabinet, a fire-fighting skylight system, a passage door system, an access control system, and a monitoring and sensing system. Data center cabinets are arranged in pairs between the base plate component and the frame component. The fire-fighting skylight system is located at the top of the data center cabinet and the frame component and can be linked with the monitoring and sensing system for automatic opening and closing control. The passage door system is located on both sides of the cold aisle and can be linked with the access control system and the monitoring and sensing system to achieve safe opening and closing as well as emergency opening and closing.
[0004] Based on the above cases and actual situations, we have found the following problems: In the use of server racks, not all racks have the same load. Some racks have low load and low heat generation, while others have high load and high heat generation. Since the incoming cold air is the same, it is easy to cause uneven distribution of cold air, which is not only wasteful but also easily affects the use of the racks. At the same time, when the rack load is too high and the internal temperature is too high, although an alarm will be sounded, it is difficult to dissipate heat in time, causing the rack to overheat and damage internal components. Summary of the Invention
[0005] The purpose of this invention is to provide an integrated hot and cold aisle cabinet with emergency air supply and exhaust modules and its application. By setting up air guide plates and drive structures, the cabinets under different loads can be precisely cooled to reduce the waste of cold air. By setting up emergency air supply components, emergency exhaust channels and emergency air supply channels are formed when the temperature is too high to provide emergency cooling for the cabinet, thereby solving the above-mentioned problems of the prior art.
[0006] To achieve the above objectives, the present invention provides an integrated hot and cold aisle cabinet with emergency air supply and exhaust modules, including a cabinet body and two rows of cabinets regularly arranged inside the cabinet body. The aisle formed between the two rows of cabinets is a cold aisle for supplying cold air, and the top of the outer side wall of the cabinet is a hot aisle for exhausting hot air. The bottom of the side wall of the cabinet is provided with an air intake component, which includes a fan hood and several air guide plates regularly arranged inside the fan hood for controlling the entry of cold air. The outer side wall of the cabinet is provided with a drive structure for controlling the opening and closing angle of the air guide plates. The drive structure includes a servo motor, a push rod that is driven and connected to the output shaft of the servo motor, and two first transmission rods that are symmetrically arranged on the left and right sides at the bottom of the push rod. A rotating rod is fixed in the middle of the inner side of the air guide plate. The first transmission rod is connected to the rotating rod at the middle position on the same side through a first gear set. The rotating rod is coaxially fixed with first driven teeth at both ends. The first driven teeth on the same side are connected through the same first tooth plate. The top of the cabinet is equipped with an emergency air outlet assembly, which includes a heat dissipation window and several baffles regularly arranged inside the heat dissipation window. The top of the heat dissipation window is equipped with an emergency exhaust ventilation structure.
[0007] In this setup, data center server racks are typically arranged in two rows with their doors facing each other. This creates a cold aisle between the rows of racks, allowing cool air to enter. During operation, the data center's air conditioning system delivers cool air into the cold aisle to cool the racks, while hot air generated by the racks is exhausted through the hot aisle. This cooling process ensures the racks' safe operation. However, not all racks operate at the same load. Some racks have low loads and generate less heat, while others have high loads and generate more heat. Since the incoming cool air is uneven, this leads to uneven cooling distribution, which is wasteful and can affect rack performance. Furthermore, when a rack is overloaded and its internal temperature becomes too high, although an alarm will sound, it's difficult to dissipate heat in time, potentially causing damage to internal components. Therefore, this technical solution uses air guides and a drive structure to precisely cool racks with different loads, reducing cool air waste. By setting up an emergency air supply component, when the temperature is too high, an emergency exhaust channel and an emergency air intake channel are automatically formed, and the exhaust structure is triggered, so that cold air can quickly and in large quantities enter the cabinet in a short time under the action of air pressure, and provide emergency cooling for the cabinet.
[0008] In the technical solution of the present invention, the servo motor is fixed to the top of the outer side wall of the cabinet, the output shaft of the servo motor passes through the outer side wall of the cabinet, a cam is fixed to the end of the output shaft of the servo motor, the larger end of the cam is coaxially fixed with the output shaft of the servo motor, a hinge rod is hinged to the smaller end of the cam, the push rod is vertically set, and the top end of the push rod is hinged to the bottom end of the hinge rod.
[0009] In this setup, by using a cam and a hinge rod, when the temperature sensor detects a high cabinet temperature, the servo motor will start and drive the cam to rotate counterclockwise, which in turn pushes the push rod downwards via the hinge rod.
[0010] In the technical solution of the present invention, the push rod is generally in the shape of an inverted T. A limiting seat is fixed in the middle of the inner side of the outer side wall of the cabinet. The middle section of the push rod passes through the limiting seat and the two are slidably connected. Vertical second tooth plates are fixed at the left and right ends of the horizontal section at the bottom of the push rod. A second driven tooth is coaxially fixed at the outer end of the first transmission rod. The second driven tooth meshes with the second tooth plate on the corresponding side.
[0011] In this setup, a limit seat restricts the position of the push rod, preventing it from wobbling and rendering the entire device unusable. By incorporating a second toothed plate, when the push rod moves downwards, the second toothed plates on both sides drive the second driven tooth to rotate, causing the first transmission rod to rotate, which in turn drives all subsequent air guide plates to rotate, increasing the opening and closing angle.
[0012] In the technical solution of the present invention, the wind cover is fixed with a dustproof plate inside the air guide plate. The dustproof plate is provided with a cleaning structure inside. The cleaning structure includes a plurality of cleaning plates arranged in a regular manner, two third toothed plates fixed to the left and right ends of the cleaning plate in the middle position, and two gears meshing with the corresponding third toothed plates. The cleaning plates are in close contact with the inner side of the dustproof plate, and the gears are coaxially fixed with the inner end of the first transmission rod on the corresponding side.
[0013] In this setup, a dustproof plate is installed to prevent cold air from carrying dust into the cabinet and damaging the components inside. A cleaning mechanism is also included; when the push rod moves downwards, it rotates the first drive rod, causing the gears on both sides to rotate synchronously with the first drive rod, which in turn moves the third gear plate downwards, thereby driving the cleaning plate to clean the surface of the dustproof plate.
[0014] In the technical solution of the present invention, a plurality of cleaning plates are arranged in parallel and adjacent cleaning plates are fixedly connected by fixing rods. Sliding rods are symmetrically fixed on the left and right sides between the upper and lower inner walls of the wind hood. The sliding rods pass through the plurality of cleaning plates and are slidably connected to the cleaning plates.
[0015] In this setup, fixed rods are used to make several cleaning plates move up and down synchronously as a whole. Sliding rods are used to limit the sliding of the cleaning plates, preventing them from detaching from the dustproof plates and thus ensuring effective cleaning.
[0016] In the technical solution of the present invention, the bottom surface of the wind baffle is symmetrically fixed with third driven teeth, and the cabinet is symmetrically provided with trigger rods near the top. The middle part of the trigger rod is a toothed plate part, which meshes with the third driven teeth. Both the inner and outer ends of the trigger rod are provided with slidably connected rod sleeves. The rod sleeves are fixed to the inner wall of the corresponding side of the cabinet, and a spring is provided between the trigger rod and the outer rod sleeve.
[0017] In this setup, a trigger rod is incorporated. When the trigger rod slides outward, the toothed plate rotates, causing the third driven tooth to rotate and open the baffle, forming an emergency ventilation channel. A spring is also included; when the spring's restoring force is triggered, it pushes the corresponding trigger rod horizontally outward, initiating subsequent structural movement.
[0018] In the technical solution of the present invention, a crossbeam is symmetrically fixed between the left and right trigger rods. Two L-shaped locking rods are fixed in the middle section of the outer crossbeam. An extension rod is fixedly connected to the push rod near the top side wall. The extension rod is symmetrically provided with locking grooves on the left and right sides. The end of the locking rod is embedded in the corresponding locking groove. The locking groove is vertically L-shaped.
[0019] In this setup, by setting up a lever and a slot, when the temperature sensor detects that the cabinet temperature is too high, the extension lever moves down synchronously with the push rod until the end of the lever slides down to the horizontal section at the bottom of the slot. At this time, the restoring force of the spring pulls the lever outward from the slot and pushes the crossbeam and the trigger levers on both sides to move outward synchronously.
[0020] In the technical solution of the present invention, the exhaust structure includes a fan blade rotatably connected to the top surface of the heat dissipation window, a rotating shaft fixed coaxially with the fan blade, and a fixed seat fixedly connected to the inner walls on both sides of the heat dissipation window. The rotating shaft is inserted into the fixed seat, and the rotating shaft and the fixed seat are rotatably connected coaxially. A spring is provided between the middle section of the rotating shaft and the fixed seat. The bottom end of the rotating shaft passes through the fixed seat and a stop block is fixedly connected to the end. The left side wall of the stop block is provided with a quarter-circle arc-shaped stop groove.
[0021] In this setup, by incorporating a spring and a stop block, when the fan blade's shaft is unobstructed, the compressed spring releases its restoring force, causing the fan blade to rotate rapidly for a short period. This drives the hot air generated by the cabinet to be quickly expelled through the emergency exhaust duct, and briefly creates a negative pressure state inside the cabinet. This allows cold air to enter the cabinet quickly and in large quantities under the influence of negative pressure, providing emergency cooling for the cabinet's interior.
[0022] In the technical solution of the present invention, a vertical third transmission rod is provided at the left end of the shaft of the third driven tooth in the middle position, and a horizontal second transmission rod is provided at the top end of the third transmission rod. The left end of the shaft of the third driven tooth and the bottom end of the third transmission rod are connected by a third gear set. The top end of the third transmission rod and the left end of the second transmission rod are connected by a second gear set. A stop rod is fixed to the upper part of the right side wall of the second transmission rod, and the stop rod is inserted into the top of the stop groove.
[0023] In this configuration, by setting a stop rod, when the toothed plate drives the third driven tooth to rotate counterclockwise, the shaft of the third driven tooth drives the third transmission rod to rotate counterclockwise synchronously through the third gear set, and under the transmission action of the second gear set, drives the second transmission rod to rotate clockwise, thereby driving the stop rod to rotate clockwise synchronously and disengage from the stop groove. At this time, the fan blade shaft is no longer obstructed.
[0024] On the other hand, the present invention also provides the application of integrated hot and cold aisle cabinets with emergency air supply and exhaust modules, which is the application of integrated hot and cold aisle cabinets with emergency air supply and exhaust modules in data center integrated hot and cold aisle cabinets.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up air guide plates and a drive structure, when the temperature sensor detects that the cabinet temperature is high, the servo motor will start and drive the cam to rotate counterclockwise, which will push the push rod downward through the hinge rod. The second toothed plates on both sides will drive the second driven teeth to rotate, which will cause the first transmission rod to rotate, thereby driving all subsequent air guide plates to rotate and increasing the opening degree, so that the amount of cold air entering matches the internal temperature of the cabinet, improving the cooling effect while reducing the waste of cold air.
[0026] 2. In this invention, by setting up a cleaning structure, when the servo motor drives the push rod to move and drives the first transmission rod to rotate, the gears on both sides rotate synchronously with the first transmission rod and drive the third gear plate to move, thereby driving the cleaning plate to clean the surface of the dustproof plate, avoiding excessive dust clogging the dustproof plate and affecting the entry of cold air.
[0027] 3. In this invention, by setting up an emergency air outlet component, when the cabinet temperature is too high, the outward extension rod moves down synchronously with the push rod until the end of the locking rod slides down to the horizontal section at the bottom of the locking slot. At this time, the restoring force of the spring pulls the locking rod outward from the locking slot and pushes the crossbeam and the trigger rods on both sides to move outward synchronously, so that the baffle plate opens vertically at 90° to form an emergency exhaust channel. At this time, the air guide plate is in a 90° horizontal opening state to form an emergency air intake channel for emergency heat dissipation of the cabinet.
[0028] 4. In this invention, by setting up an exhaust structure, when the cabinet temperature is too high, the toothed plate drives the third driven tooth to rotate counterclockwise. The shaft of the third driven tooth, through the sequential transmission of the third gear set, the third transmission rod, and the second gear set, drives the second transmission rod to rotate clockwise, which in turn drives the stop rod to rotate 90° clockwise and disengage from the stop groove. At this time, the fan blade shaft is unobstructed, and the compressed spring will release its restoring force, pushing the fan blade to rotate rapidly in a short time. This causes the hot air generated in the cabinet to be quickly discharged from the emergency exhaust channel, and the air pressure inside the cabinet to briefly present a negative pressure state. This allows cold air to enter the cabinet quickly and in large quantities under the action of negative pressure, providing emergency heat dissipation for the cabinet and protecting the components inside the cabinet.

[0030] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0031] Unless otherwise expressly stated, throughout this specification, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0032] Reference Figures 1-14 As shown, this embodiment provides a technical solution: Integrated hot and cold aisle cabinets with emergency air supply and exhaust modules are used in data center integrated hot and cold aisle cabinets. They include a cabinet body 100 and two rows of cabinets 101 arranged regularly within the cabinet body 100. The outer wall of each cabinet 101, near the top, forms a hot aisle 102 for exhausting hot air. In the data center cabinet body 100, the cabinets 101 are typically arranged in two rows with their doors facing each other, creating a cold aisle 103 between the two rows of cabinets 101. During operation, the data center's air conditioning system delivers cold air into the cold aisle 103 to cool the cabinets 101, while the hot air generated by the cabinets 101 is exhausted through the outer hot aisle 102, preventing the mixing of hot and cold air and thus avoiding reduced cooling efficiency. This is existing technology in data centers and will not be elaborated upon here.
[0033] The side wall of the cabinet 101 is provided with an air intake component 200 near the bottom. The air intake component 200 includes a fan hood 201 and several air guides 202 regularly arranged inside the fan hood 201 to control the entry of cold air. The inner side wall of the cabinet 101 is provided with a drive structure 210 for controlling the opening and closing angle of the air guides 202. The cold air in the cold aisle 103 enters from the air intake component 200 of each cabinet 101, and the opening and closing angle of the air guides 202 controls the amount of cold air entering, so as to achieve precise cooling of the cabinets 101 with different loads and reduce the waste of cold air.
[0034] The drive structure 210 includes a servo motor 211, a push rod 212 connected to the output shaft of the servo motor 211, and two first transmission rods 214 symmetrically arranged at the bottom of the push rod 212. It should be noted that each cabinet 101 is equipped with a temperature sensor near the hot aisle 102. The servo motor 211 is started by the temperature sensor; the specific connection method is existing technology and will not be described in detail here. When the temperature sensor detects a high temperature in the cabinet 101, the servo motor 211 starts and drives the push rod 212 downwards, which in turn rotates the first transmission rods 214 on both sides.
[0035] A rotating rod 2021 is fixed to the middle of the inner side of the air guide plate 202. The front end of the first transmission rod 214 is connected to the rotating rod 2021 at the middle position on the same side through a first gear set 2142. The rotating rod 2021 is coaxially fixed with first driven teeth 2022 at both ends. The first driven teeth 2022 on the same side are connected through the same first toothed plate 2023. When the first transmission rod 214 rotates, it drives the rotating rod 2021 at the middle position to rotate through the first gear set 2142. In turn, the first toothed plate 2023 and the first driven teeth 2022 drive all the air guide plates 202 to rotate, increasing the opening and closing degree, thereby increasing the amount of cold air entering and cooling the cabinet 101.
[0036] The top of the rack 101 is equipped with an emergency air outlet assembly 300, which includes a heat dissipation window 301 and several baffles 302 regularly arranged within the heat dissipation window 301. An emergency exhaust ventilation structure 310 is located at the top of the heat dissipation window 301. By setting up the emergency air outlet assembly 300, when the temperature sensor detects that the temperature of the rack 101 is higher than the preset safe temperature, the baffles 302 will open, increasing the area of the total air outlet channel. Simultaneously, the exhaust ventilation structure 310 will be triggered, creating negative pressure inside the rack 101. At this time, cold air enters the rack 101 rapidly and in large quantities under the action of air pressure, providing emergency cooling for the rack 101. In addition, the air guide plate 202 is horizontal at this time, ensuring the maximum cross-sectional area of the air intake channel, forming an emergency air intake channel.
[0037] Please see Figures 1-5As shown, the servo motor 211 is fixed to the top of the outer side wall of the cabinet 101, and the output shaft of the servo motor 211 passes through the outer side wall of the cabinet 101.
[0038] Specifically, a cam 2111 is fixed to the end of the output shaft of the servo motor 211. The larger end of the cam 2111 is coaxially fixed with the output shaft of the servo motor 2111, and a hinge rod 2112 is hinged to the smaller end of the cam 2111. The push rod 212 is vertically arranged, and the top end of the push rod 212 is hinged to the bottom end of the hinge rod 2112. When the temperature sensor detects that the temperature of the cabinet 101 is high, the servo motor 211 will start and drive the cam 2111 to rotate counterclockwise, which will push the push rod 212 downward through the hinge rod 2112.
[0039] Please see Figure 5 and Figure 7 As shown, the push rod 212 is generally inverted T-shaped. A limit seat 2121 is fixed to the middle of the inner side of the outer side wall of the cabinet 101. The middle section of the push rod 212 passes through the limit seat 2121 and the two are slidably connected. The limit seat 2121 is used to limit the position of the push rod 212 and prevent the push rod 212 from shaking, which would render the entire device unusable.
[0040] In addition, vertical second toothed plates 213 are fixed to the left and right ends of the horizontal section at the bottom of the push rod 212, and a second driven tooth 2141 is coaxially fixed to the outer end of the first transmission rod 214. The second driven tooth 2141 meshes with the corresponding second toothed plate 213. By setting the second toothed plates 213, when the push rod 212 moves downward, the second toothed plates 213 on both sides will drive the second driven tooth 2141 to rotate, thereby causing the first transmission rod 214 to rotate, which in turn drives all subsequent air guide plates 202 to rotate, increasing the opening and closing degree.
[0041] Please see Figures 8-9 As shown, the fan cover 201 is located inside the air guide plate 202 and a dustproof plate 203 is fixed thereon. By setting the dustproof plate 203, cold air carrying dust is prevented from entering the cabinet 101 and causing damage to the parts inside the cabinet 101.
[0042] Specifically, a cleaning structure 220 is provided on the inner side of the dustproof plate 203. The cleaning structure 220 includes several cleaning plates 221 arranged in a regular manner, two third toothed plates 223 fixed to the left and right ends of the cleaning plate 221 in the middle position, and two gears 224 that mesh with the corresponding third toothed plates 223. The cleaning plates 221 are in close contact with the inner side of the dustproof plate 203, and the gears 224 are coaxially fixed with the inner end of the corresponding first transmission rod 214.
[0043] By setting up the cleaning structure 220, when the push rod 212 moves down and drives the first transmission rod 214 to rotate, the gears 224 on both sides rotate synchronously with the first transmission rod 214 and drive the third tooth plate 223 to move downward, thereby driving the cleaning plate 221 to clean the surface of the dustproof plate 203.
[0044] It should be noted that since the first transmission rod 214 drives the air guide plate 202 to rotate at a relatively small angle, the gear 224 also rotates at a relatively small angle. Since the dustproof plate 203 needs to be supplied with cold air, too many cleaning plates 221 cannot be provided. In order to ensure that the movement of the cleaning plate 221 can completely clean the surface of the dustproof plate 203, the diameter of the gear 224 must be larger than the rod diameter of the first transmission rod 214. This ensures that when the rotation angle is small, the distance that it drives the cleaning plate 221 to move is sufficient to clean the entire surface of the dustproof plate 203.
[0045] In addition, several cleaning plates 221 are arranged in parallel, and adjacent cleaning plates 221 are fixedly connected by fixing rods 222. By setting the fixing rods 222, the several cleaning plates 221 form a whole and move up and down synchronously. Sliding rods 225 are symmetrically fixed on the left and right sides between the upper and lower inner walls of the fan cover 201. The sliding rods 225 pass through the several cleaning plates 221 and are slidably connected to the cleaning plates 221. By setting the sliding rods 225, the sliding of the cleaning plates 221 is limited, so as to prevent the cleaning plates 221 from detaching from the dustproof plate 203 and failing to achieve the cleaning effect.
[0046] Please see Figures 10-12 As shown, the bottom surface of the baffle plate 302 is symmetrically fixed with third driven teeth 303. Inside the cabinet 101, near the top, symmetrically arranged trigger rods 304 have a toothed plate in the middle, which meshes with the third driven teeth 303. By setting the trigger rod 304, when it slides outward, the toothed plate will drive the third driven teeth 303 to rotate, thereby causing the baffle plate 302 to rotate and open, forming an emergency ventilation channel.
[0047] Furthermore, both the inner and outer ends of the trigger rod 304 are slidably connected to rod sleeves 3041. The rod sleeves 3041 are fixed to the corresponding inner wall of the cabinet 101. A spring 306 is provided between the trigger rod 304 and the outer rod sleeve 3041. By providing the spring 306, when the restoring force of the spring 306 is triggered, it will push the corresponding trigger rod 304 to slide horizontally outward, thereby triggering the subsequent structural movement.
[0048] Please see Figure 6 and Figure 11As shown, a crossbeam 305 is symmetrically fixed between the left and right trigger rods 304, and two L-shaped locking rods 3051 are fixed in the middle section of the outer crossbeam 305. An extension rod 215 is fixedly connected to the push rod 212 upward near the top side wall. The extension rod 215 has symmetrically provided slots 2151 on the left and right sides. The ends of the locking rods 3051 are embedded in the corresponding slots 2151. The slots 2151 are vertically L-shaped, and the ends of the locking rods 3051 are slidably connected to the corresponding slots 2151.
[0049] By setting up the lever 3051 and the slot 2151, when the temperature sensor detects that the temperature of the cabinet 101 is too high, the extension rod 215 moves down synchronously with the push rod 212 until the end of the lever 3051 slides down to the horizontal section at the bottom of the slot 2151. At this time, the restoring force of the spring 306 pulls the lever 3051 outward from the slot 2151 and pushes the crossbeam 305 and the trigger rods 304 on both sides to move outward synchronously.
[0050] Please see Figure 13 and Figure 14 As shown, a vertical third transmission rod 317 is provided at the left end of the shaft of the third driven gear 303 in the middle position. A horizontal second transmission rod 316 is provided at the top of the third transmission rod 317. The left end of the shaft of the third driven gear 303 and the bottom end of the third transmission rod 317 are connected by a third gear set 3171. The top end of the third transmission rod 317 and the left end of the second transmission rod 316 are connected by a second gear set 3162. A stop rod 3161 is fixed to the upper part of the right side wall of the second transmission rod 316, and the stop rod 3161 is inserted into the top of the stop groove 3151. A support member is rotatably connected to the wall of the second transmission rod 316, and the top of the support member is fixed to the left side of the inner top surface of the heat dissipation window 301.
[0051] When the toothed plate drives the third driven tooth 303 to rotate counterclockwise, the shaft of the third driven tooth 303 drives the third transmission rod 317 to rotate counterclockwise through the third gear set 3171, and drives the second transmission rod 316 to rotate clockwise under the transmission action of the second gear set 3162, which in turn drives the stop rod 3161 to rotate clockwise in sync. It should be noted that at this time, the opening and closing angle of the wind deflector 302 needs to be at its maximum. Therefore, the wind deflector 302 needs to change from a horizontal state to a vertical state, which requires a 90° rotation. Therefore, the third driven tooth 303 needs to rotate 90°.
[0052] Specifically, the exhaust structure 310 includes a fan blade 311 rotatably connected to the top surface of the heat dissipation window 301, a rotating shaft 312 fixed coaxially with the fan blade 311, and a fixed seat 313 fixedly connected to the inner walls on both sides of the heat dissipation window 301. The rotating shaft 312 is inserted into the fixed seat 313, and the rotating shaft 312 and the fixed seat 313 are rotatably connected coaxially. A spring-loaded spring 314 is provided between the middle section of the rotating shaft 312 and the fixed seat 313. The bottom end of the rotating shaft 312 passes through the fixed seat 313 and is fixedly connected to a stop block 315. The left side wall of the stop block 315 is provided with a quarter-circle arc-shaped stop groove 3151.
[0053] By setting up a spring 314 and a stop block 315, when the stop rod 3161 rotates 90° clockwise and disengages from the stop groove 3151, the rotating shaft 312 of the fan blade 311 is no longer obstructed. The compressed spring 314 will release its restoring force and push the fan blade 311 to rotate rapidly in a short time, thereby driving the hot air generated by the cabinet 101 to be quickly discharged from the emergency exhaust channel. This also causes the air pressure inside the cabinet 101 to briefly present a negative pressure state, allowing cold air to enter the cabinet 101 quickly and in large quantities under the action of negative air pressure, thus providing emergency heat dissipation for the inside of the cabinet 101.
