Description
Technical Field
[0001] This invention belongs to the field of electrical communication selection device technology, specifically a switch cabinet for improving the heat dissipation efficiency of a switch. Background Technology
[0002] With the large-scale deployment of gigabit, 10-gigabit, and high-power PoE switches in data centers, the integration, port density, and power consumption of switches continue to increase. Individual switches generate significant heat, and when multiple switches are vertically stacked in a standard switch cabinet, heat accumulation becomes a prominent issue. Prolonged high-temperature operation can lead to problems such as optical module packet loss, chip frequency reduction, port failures, and even system crashes, significantly shortening the switch's lifespan. Therefore, the heat dissipation structure of the switch cabinet directly determines the long-term operational stability of the communication network.
[0003] In existing technologies, industry-standard switch cabinets primarily rely on fixed cooling fans at the top and back of the cabinet, combined with louvered ventilation holes in the cabinet walls, to achieve natural and enhanced forced air cooling. For example, a switch cooling cabinet disclosed in publication number CN214879874U has cooling fans installed at the top and bottom of the cabinet, relying on vertical convection to remove heat from the cabinet; this is currently the most widely used basic cooling cabinet solution. Meanwhile, switch storage cooling cabinets disclosed in publication number CN221264334U incorporate layered airflow channels, delivering cool air to each switch mounting layer through distribution ducts, thus improving the layered cooling effect to some extent.
[0004] While the two types of existing switch cabinets mentioned above can achieve basic ventilation and heat dissipation, in actual long-term use in computer rooms, because the nuts and mounting plates are fixedly connected, it is impossible to independently fine-tune the height of a particular plate without affecting other plates. In scenarios where switches are installed layer by layer, after the upper support platform descends to contact the top surface of the installed switches, if further height adjustments are needed to avoid damaging the equipment or to leave a heat dissipation gap, operators can only manually disassemble the fixing bolts or rotate the threaded rod as a whole, which is cumbersome and difficult to accurately position. Moreover, the locking structure instantly and completely fails the moment the support platform descends with the load and the threaded lock is released. Without a transition buffer and auxiliary locking structure, the support platform is prone to sudden drop or slippage, impacting or damaging the installed switch equipment below. The single threaded locking structure relies on the friction of the thread engagement to support the weight and load of the equipment. After frequent lifting and lowering adjustments, the threads are prone to wear, stripping, jamming, and other problems, and the locking stability continues to decline. Meanwhile, in the existing solution, the height adjustment of the carrier platform and the installation and positioning of the switch are two independent operations. It is impossible to use the installation action of the switch itself to trigger the automatic unlocking and locking of the carrier platform, resulting in low installation efficiency and cumbersome operation steps.
[0005] While semi-circular clamps have been used in the field of communication cabinets, such as in patch panels for securing communication cables and in wire clamps inside server cabinets, these semi-circular clamps are static clamping elements. Their function is limited to clamping and fixing cables in a certain position, resulting in a stationary state after clamping, without involving any form of relative movement or state switching.
[0006] Therefore, the present invention provides a switch cabinet for improving the heat dissipation efficiency of a switch. Summary of the Invention
[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a switch cabinet for improving the heat dissipation efficiency of a switch, comprising a cabinet body, an exhaust port at the bottom front end of the cabinet body, a mesh plate on the rear wall of the cabinet body, a collection chamber at the top end of the cabinet body, an exhaust port on the inner wall of the collection chamber and the exhaust port communicating with the cabinet body, and an adjustment assembly provided in the cabinet body, wherein multiple support platforms are installed between the adjustment assemblies; The adjustment assembly includes grooves formed on both sides of the inner cavity of the cabinet. A threaded rod is rotatably connected to the inner cavity of the groove. Multiple threaded clamps are threadedly connected to the outside of the threaded rod. Each threaded clamp is configured as two semi-circular clamps, which are spliced together to form an integral threaded clamp. One end of the threaded clamp is slidably installed on the support platform. By driving the threaded rod to rotate, the threaded clamp can drive the support platform to move synchronously, thereby adjusting the distance between the multiple support platforms.
[0009] Preferably, a first T-shaped groove is provided on both sides of the bearing platform, and the threaded clamp is slidably connected in the inner cavity of the first T-shaped groove. A compression spring is fixedly connected to both ends of the inner cavity of the first T-shaped groove, and one end of the compression spring is fixedly connected to the threaded clamp.
[0010] Preferably, a second T-shaped groove is provided at the bottom of the inner cavity of the first T-shaped groove, and a T-shaped insert is slidably connected to the inner cavity of the second T-shaped groove. One end of the T-shaped insert is set as an inclined arc surface, and two first springs are fixedly connected to the other end. One end of the first spring is fixedly connected to the bottom of the second T-shaped groove. By driving the T-shaped insert to squeeze the first spring, the T-shaped insert can be inserted between the threaded clamps, so that the threaded clamps squeeze the springs and disengage from the threaded rod.
[0011] Preferably, through slots are provided at the four corners on both sides of the support platform, and the two ends of the second T-shaped slide groove are connected to the through slots. A T-shaped slider is slidably connected to the inner cavity of the through slot. The T-shaped slider is set with an inclined arc surface on the side near the second T-shaped slide groove. Two second springs are fixedly connected to one end of the T-shaped slider, and one end of the second spring is fixedly connected to the bottom of the through slot.
[0012] Preferably, two toothed grooves are provided on both sides of the inner cavity of the cabinet, and the T-shaped slider is inserted into the toothed grooves for fixing the support platform.
[0013] Preferably, the inner cavity of the first T-shaped groove is slidably connected with four sliding frames, and each pair of sliding frames is arranged as a group. The lower ends of the two sliding frames are rotatably connected with push blocks, and the inner cavities at the other ends are rotatably connected with abutment blocks for pressing the T-shaped slider and the T-shaped insert.
[0014] Preferably, an air inlet is provided at the lower end of the cabinet, and a spiral air guide groove is provided inside the lower end of the cabinet. The spiral air guide groove is located at the center and communicates with the air inlet. One end of the spiral air guide groove is connected to the exhaust port. A metal sintered mesh is laid in the inner cavity of the spiral air guide groove to turbulent and uniformly flow the air, prolong the airflow residence time, realize the premixing of hot and cold air, and reduce the risk of condensation caused by the high temperature generated by the exchanger inside the cabinet 1.
[0015] Preferably, a sealing cover is installed on the upper end of the cabinet, a folding tube is fixedly connected to the upper end of the sealing cover, a fixing frame is fixedly connected to the inner cavity of the sealing cover, a servo motor is fixedly connected to the upper end of the fixing frame, a T-shaped rotating cylinder is fixedly connected to the output shaft end of the servo motor, an exhaust fan is fixedly connected to the outside of the T-shaped rotating cylinder, and a temperature and humidity monitor is installed at the top of the inner cavity of the cabinet for real-time monitoring of the temperature and humidity inside the cabinet.
[0016] Preferably, the inner cavity of the T-shaped rotating cylinder is rotatably connected to an umbrella-shaped gear disk, which is meshed with multiple umbrella gears. Each umbrella gear has an adjusting blade fixedly connected to one end through the T-shaped rotating cylinder. The umbrella gears are rotatably connected to the T-shaped rotating cylinder. A drive shaft is fixedly connected to the lower end of the umbrella-shaped gear disk, and a control motor is fixedly connected to one end of the drive shaft. This motor drives the drive shaft to rotate the umbrella-shaped gear disk, which in turn meshes with the drive umbrella gears to drive the adjusting blades to adjust the tilt angle. This allows the air extraction efficiency to be adjusted according to the temperature and humidity inside the cabinet cavity.
[0017] Preferably, the lower end of the cabinet is fixedly connected to a base, and the inner cavity of the base is provided with a lifting mechanism. The lower end of the lifting mechanism is fixedly connected to a sliding mesh plate, and the lower end of the sliding mesh plate is equipped with casters at the four corners.
[0018] The beneficial effects of this invention are as follows: This invention describes a switch cabinet for improving the heat dissipation efficiency of a switch. When the device is in normal operation without unlocking, the two semi-circular clamps are continuously pre-tightened by springs on both sides, ensuring a tight engagement between the threaded clamps and the threaded rod throughout the entire process. The rotation of the threaded rod stably drives the support platform to rise and fall synchronously, with high precision in adjusting the interlayer gap. When the sliding frame pushes the T-shaped insert to extend towards the center, the inclined arc surface of the T-shaped insert weds between the two semi-circular clamps, opening the semi-circular clamps to both sides. The semi-circular clamps overcome the spring force and slide towards both ends of the first T-shaped groove, completely disengaging the thread and the threaded rod. At this time, the support platform is no longer constrained by the threaded rod, allowing for quick manual lifting or lowering for fine-tuning of the height without disassembling any fasteners. When the switch is removed and the unlocking force disappears, the spring elastically retracts, automatically pushing the two semi-circular clamps together to form the threaded clamps. Furthermore, a strong magnet is installed inside the two semi-circular clamps, which, in conjunction with the strong magnet, quickly closes them to form the threaded clamps. The thread re-engages with the threaded rod, restoring rigid lifting transmission, thus meeting both precise fine-tuning and rapid loading / unloading requirements.
[0019] This invention describes a switch cabinet for improving the heat dissipation efficiency of switches. During switch installation, a first spring pulls a T-shaped plug into a second T-shaped groove, preventing it from contacting the threaded clamp. The threaded clamp remains locked, and the threaded rod allows for normal adjustment of the shelf height. After the switch is installed on the bottom support platform of the cabinet, the threaded rod drives the threaded clamp to move the upper support platform downwards. The push block of the support platform abuts against the top surface of the switch, simultaneously pushing the sliding frame to slide. The side blocks press against the tail of the T-shaped plug, causing the T-shaped plug to extend beyond the spring tension. The wedge surface opens the threaded clamp, separating the thread from the threaded rod. The support platform is then released from constraint and its height can be freely adjusted. After the switch is removed, the push block loses its load, the sliding frame and the block return to their original positions, the T-shaped plug is pulled back by the spring, and the semi-circular clamp re-closes under the action of the compression spring and a strong magnet. This design avoids the problems of traditional switch cabinets where the interlayer gaps are not adjustable, low-profile switches have ineffective upper spaces, and tall switches have narrow interlayers leading to poor airflow, heat accumulation, high-temperature alarms, and accelerated component aging.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] Example 1, as Figure 1 , Figure 2 and Figure 4 As shown in the figure, a switch cabinet for improving the heat dissipation efficiency of a switch according to an embodiment of the present invention includes a cabinet body 1. An exhaust port 12 is provided at the front end of the bottom of the inner cavity of the cabinet body 1. A grid plate is provided on the rear wall of the inner cavity of the cabinet body 1. A collection cavity 10 is provided at the upper end of the cabinet body 1. An exhaust port 11 is provided on the inner wall of the collection cavity 10 and is connected to the inner cavity of the cabinet body 1. An adjustment assembly 7 is provided in the inner cavity of the cabinet body 1. Multiple support platforms 5 are installed between the adjustment assemblies 7. The adjustment component 7 includes grooves 71 formed on both sides of the inner cavity of the cabinet 1. A threaded rod 72 is rotatably connected to the inner cavity of the groove 71. Multiple threaded clamps 73 are threadedly connected to the outside of the threaded rod 72. Each threaded clamp 73 is configured as two semi-circular clamps, which are spliced together to form an integral threaded clamp 73. One end of the threaded clamp 73 is slidably installed with the support platform 5. By driving the threaded rod 72 to rotate, the threaded clamp 73 can drive the support platform 5 to move synchronously, which can adapt to the spacing adjustment requirements of installing switches layer by layer from bottom to top.
[0024] Specifically, in the existing technology, the traditional switch cabinet shelves are fixed welded structures with non-adjustable gaps between shelves. When low-profile switches are placed, too much unused space is reserved at the top, while when tall switches are placed, the gaps between shelves are narrow, and the equipment is tightly attached to the shelves on all four sides, blocking the airflow channels and causing continuous accumulation of working heat. This can easily trigger high-temperature alarms and accelerate the aging of components.
[0025] When the spacing between multiple support platforms 5 needs to be adjusted to accommodate switches of different heights, this invention uses an external drive mechanism to rotate a threaded rod 72 around its own axis. The threaded rod 72 uses its external thread to form a threaded transmission with the internal thread of the threaded clamp 73, thereby causing the threaded clamp 73 to move synchronously along the axial direction of the threaded rod 72. This achieves proportional adjustment of the spacing between multiple support platforms 5, ensuring that the height of each support platform 5 is precisely matched with the installed switch. This avoids the problem of traditional fixed shelves where large switches cannot be installed or where space is wasted after installing small switches due to the non-adjustable spacing. When the threaded rod 72 drives all the threaded clamps 73 to move upward synchronously through thread engagement, the threaded clamps 73 drive the support platforms 5 to rise synchronously, expanding the upper... The vertical heat dissipation gap between the lower support platforms 5 drives the threaded rod 72 to rotate in the opposite direction. The threaded clamp 73 moves downward along the threaded rod 72, and the support platform 5 descends synchronously, reducing the installation height between layers. The air duct can be precisely matched according to the height of the switch body. Under normal conditions, the compression spring 74 continuously squeezes the two semi-circular clamps in the middle to ensure that the internal threads are completely in contact with the threaded rod 72. The threaded transmission is smooth without slippage, and the lifting and lowering of the support platform 5 is synchronous without deviation. When the T-shaped insert 710 is wedged between the two semi-circular clamps, the semi-circular clamps slide towards both ends of the first T-shaped slide groove 75 to squeeze the compression spring 74. The thread disengages from the threaded rod 72, and the support platform 5 can be freed from the thread constraint and its height can be freely adjusted. The dual structure can not only adjust precisely but also unlock quickly, adapting to the rapid loading and unloading of batch switches, thereby solving the above problems.
[0026] like Figures 4 to 6 As shown, the bearing platform 5 has a first T-shaped groove 75 on both sides. The threaded clamp 73 is slidably connected in the inner cavity of the first T-shaped groove 75. A compression spring 74 is fixedly connected to both ends of the inner cavity of the first T-shaped groove 75. One end of the compression spring 74 is fixedly connected to the threaded clamp 73. A strong magnet is set inside the two semi-circular clamps located at both ends of the inner cavity of the first T-shaped groove 75.
[0027] Specifically, during normal operation without unlocking, the two side springs 74 continuously pre-tighten the two semi-circular clamps, ensuring that the threaded clamp 73 and the threaded rod 72 are tightly engaged throughout the entire process. The rotation of the threaded rod 72 can stably drive the bearing platform 5 to rise and fall synchronously, with high precision in adjusting the interlayer gap. When the sliding frame 714 pushes the T-shaped insert 710 to extend towards the middle, the inclined arc surface of the T-shaped insert 710 weds between the two semi-circular clamps, opening the semi-circular clamps to both sides. The semi-circular clamps overcome the elastic force of the springs 74 and slide towards both ends of the first T-shaped slide groove 75. The thread and the threaded rod 72 are completely disengaged. At this time, the bearing platform 5 is no longer constrained by the threaded rod 72, and its height can be finely adjusted by manual quick lifting or lowering. No fasteners need to be disassembled or reassembled. When the switch is removed and the external force for unlocking disappears, the spring 74 elastically retracts, automatically pushing the two semi-circular clamps together to form a threaded clamp 73. Moreover, a strong magnet is set inside the two semi-circular clamps, which, together with the strong magnet, makes them quickly close to form the threaded clamp 73. The threads re-engage the threaded rod 72, restoring the rigid lifting transmission. This can meet the dual needs of precise fine adjustment and rapid installation and removal, thus solving the problem that existing switch cabinets used to improve the heat dissipation efficiency of switches rely on only a single thread to lock the traditional adjustable cabinet shelves. Unlocking requires manual disassembly of the fastening bolts, which is a cumbersome disassembly and assembly process and cannot quickly adjust the shelf height, resulting in extremely low efficiency for batch debugging in computer rooms.
[0028] like Figures 4 to 6 As shown, a second T-shaped groove 76 is provided at the bottom of the inner cavity of the first T-shaped groove 75. A T-shaped insert 710 is slidably connected to the inner cavity of the second T-shaped groove 76. One end of the T-shaped insert 710 is set as an inclined arc surface, and two first springs 79 are fixedly connected to the other end. One end of the first spring 79 is fixedly connected to the bottom of the second T-shaped groove 76. By driving the T-shaped insert 710 to squeeze the first spring 79, the T-shaped insert 710 can be inserted between the threaded clamps 73, so that the threaded clamps 73 squeeze the compression spring 74 and disengage the threaded rod 72 from the threaded connection.
[0029] Specifically, during switch installation, the first spring 79 continuously pulls the T-shaped plug 710 backward, causing it to be completely retracted into the second T-shaped slide groove 76 without contacting the threaded clamp 73. The threaded clamp 73 remains engaged and locked, allowing the threaded rod 72 to adjust the shelf height normally. The switch is then installed onto the support platform 5 at the bottom of the cabinet 1. At this time, the threaded rod 72 drives the threaded clamp 73 to move the upper support platform 5 downward. The support platform 5 causes the push block 78 to move downward and abut against the top surface of the switch. Simultaneously, the push block 78 pushes the sliding frame 714 to slide towards the center of the second T-shaped slide groove 76. The two side blocks 713 simultaneously press against the tail of the T-shaped plug 710, causing the T-shaped plug 710 to extend forward against the pull of the first spring 79, forming an inclined wedge. The two semi-circular clamps are inserted between the two pieces, and the threaded clamp 73 is opened laterally. The thread and the threaded rod 72 are separated, and the bearing platform 5 automatically releases the thread constraint, allowing for free fine adjustment of the height. After the switch is removed, the push block 78 loses its downward pressure load, the sliding frame 714 and the stop block 713 are reset, the T-shaped plug 710 has no lateral squeezing force, the first spring 79 rebounds and pulls the T-shaped plug 710 back, and the semi-circular clamps re-close and mesh under the action of the compression spring 74 and the strong magnet. This avoids the situation where the gap between the shelves of the traditional switch cabinet is not adjustable, the upper part is left with too much ineffective space when the low switch is placed, and the gap between the shelves is narrow when the tall switch is placed. The equipment is tightly attached to the shelves on all four sides, the airflow channel is blocked, the working heat continues to accumulate, and it is very easy to trigger the high temperature alarm of the equipment, causing the components to age faster.
[0030] like Figures 4 to 6 As shown, through slots 77 are provided at the four corners on both sides of the support platform 5. The two ends of the second T-shaped slide groove 76 are connected to the through slots 77. A T-shaped slider 711 is slidably connected to the inner cavity of the through slot 77. The side of the T-shaped slider 711 near the second T-shaped slide groove 76 is set with an inclined arc surface. Two second springs 712 are fixedly connected to one end of the T-shaped slider 711, and one end of the second spring 712 is fixedly connected to the bottom of the through slot 77. Two toothed grooves 8 are provided on both sides of the inner cavity of the cabinet 1. The T-shaped slider 711 is inserted into the toothed grooves 8 to fix the support platform 5. Four sliding frames 714 are slidably connected to the inner cavity of the first T-shaped slide groove 75, and each pair of sliding frames 714 is set as a group. A push block 78 is rotatably connected to the lower end of each of the two sliding frames 714, and a stop block 713 is rotatably connected to the inner cavity of the other end to press the T-shaped slider 711 and the T-shaped insert block 710.
[0031] Specifically, two toothed grooves 8 are provided on both sides of the inner cavity of the cabinet 1. When the support platform 5 is not carrying the switch or is in a high position awaiting installation, the second spring 712 is in a naturally extended state, continuously pushing the T-shaped slider 711 into the through groove 77, causing the T-shaped slider 711 to retract into the through groove 77. The threaded clamp 73 and the threaded rod 72 are threadedly connected to form a rigid mechanical lock, preventing the support platform 5 from slipping or falling under its own weight and the weight of the switch. During the process of installing the switch layer by layer from bottom to top, when the support platform 5 carries... When the switch descends and contacts the top surface of the switch below, the push block 78 is pushed upward and moves outward through the sliding bracket 714, causing the abutment block 713 to move outward. The outer end of the abutment block 713 pushes the inclined arc surface of the T-shaped insert 710, causing the T-shaped insert 710 to insert into the threaded clamp 73, thereby disengaging the threaded clamp 73 from the threaded rod 72. At the same time, the abutment block 713 pushes the T-shaped slider 711, squeezing the second spring 712 out of the through groove 77, causing the outer end of the T-shaped slider 711 to insert into the inner cavity of the toothed groove 8, between the support platform 5 and the side wall of the cabinet 1. The locking mechanism prevents the support platform 5 from suddenly falling and damaging the switch after the threaded clamp 73 and threaded rod 72 are connected. It also automatically reserves heat dissipation space between the support platform 5 and the switch below, preventing the support platform 5 from being too tightly attached to the switch and affecting the switch's heat dissipation efficiency. This solves the problem that existing switch cabinets used to improve the heat dissipation efficiency of switches usually only have a single-stage threaded locking structure for the support platform 5. When the switches and support platforms are installed layer by layer, the locking structure will instantly fail completely when the load is lowered and the threaded lock is released. Without a transition buffer and auxiliary locking structure, the support platform 5 is prone to sudden drop or slippage, which may cause it to hit or damage the switch equipment that has been installed below. Moreover, the single threaded locking structure relies on the friction of the thread engagement to support the weight and load of the equipment. After long-term use or frequent lifting and lowering adjustments, the threads are prone to wear or stripping and jamming. The locking stability will continue to decline, and the support platform 5 may become loose, offset, or mispositioned. The installation accuracy of the equipment and the overall assembly firmness of the cabinet 1 are difficult to guarantee.
[0032] like Figure 2 , Figure 3 and Figure 11 As shown, an air inlet 9 is provided at the lower end of the cabinet 1, and a spiral air guide groove 21 is provided inside the lower end of the cabinet 1. The spiral air guide groove 21 is located at the center and is connected to the air inlet 9. One end of the spiral air guide groove 21 is connected to the exhaust port 12. The inner cavity of the spiral air guide groove 21 is lined with a sintered metal mesh for turbulence and uniform flow, extending the airflow residence time, realizing the premixing of hot and cold air, and reducing the phenomenon of condensation caused by the high temperature generated by the exchanger inside the cabinet.
[0033] Specifically, ambient temperature air in the server room is drawn in through air inlet 9 and slowly flows along the spiral path after entering the spiral air guide channel 21. The sintered metal mesh forms multiple obstructions and turbulences on the airflow, dispersing the concentrated airflow and achieving uniform flow throughout the entire area. This prolongs the residence time of the cold air inside the channel, allowing for thorough heat exchange and premixing between the low-temperature air and the high-temperature heat conducted from the cabinet base plate. This significantly reduces the temperature difference between the cold and hot air, preventing the low-temperature air from directly contacting the high-temperature cabinet wall 1 and the switch housing, thus avoiding condensation caused by temperature differences and preventing short circuits due to moisture in the components inside the cabinet. The preheated air after heat exchange is then horizontally ejected from exhaust outlet 12, forming a uniform horizontal air curtain at the bottom of the cabinet 1. It then passes upward through the heat dissipation gaps between the support platforms 5, carrying away the heat generated by the switch operation layer by layer. Finally, the hot air gathers upward to the top of the cabinet 1. The collection chamber 10, while the cabinet 1 remains sealed, reduces the noise generated during the operation of the switch cabinet. This addresses the problem that existing switch cabinets designed to improve heat dissipation efficiency often have a direct-flow, open-hole structure, resulting in concentrated and disordered airflow. The bottom intake directly impacts the lower-level equipment, causing excessive airflow in the lower level and insufficient airflow in the upper level. This leads to uneven heat dissipation among the switches in the cabinet, resulting in long-term heat accumulation in the upper level and localized overheating. The overall heat dissipation efficiency is low due to poor heat dissipation consistency. Furthermore, open-ventilation cabinets lack a sealed airflow channel, allowing unrestricted airflow in and out. This causes turbulent and opposing airflows, with operating noise spreading directly outwards, resulting in excessive noise levels in the computer room and poor equipment quietness, which fails to meet the noise reduction and maintenance requirements of high-standard computer rooms.
[0034] like Figure 1 , Figures 8 to 10 As shown, a sealing cover 3 is installed on the upper end of the cabinet 1. A folding tube 6 is fixedly connected to the upper end of the sealing cover 3. A fixing frame 15 is fixedly connected to the inner cavity of the sealing cover 3. A servo motor 14 is fixedly connected to the upper end of the fixing frame 15. A T-shaped rotating cylinder 20 is fixedly connected to the output shaft end of the servo motor 14. An exhaust fan 13 is fixedly connected to the outside of the T-shaped rotating cylinder 20. A temperature and humidity monitor is installed at the top of the inner cavity of the cabinet 1 to monitor the temperature and humidity of the inner cavity of the cabinet 1 in real time.
[0035] Specifically, when there are differences in the installation spacing and height of the exhaust ducts at the top of the computer room, the folded pipe 6 can be stretched or compressed to match the pipe height. The flange is sealed and connected to the computer room exhaust duct. The sealing cover 3 completely covers the collection chamber 10 at the top of the cabinet 1, forming a closed negative pressure air duct. All hot air in the cabinet can only enter the sealing cover 3 through the exhaust port 11, and then be discharged to the computer room exhaust duct through the folded pipe 6. This avoids the high-temperature exhaust gas from the switch from directly diffusing into the computer room and causing an overall increase in room temperature. Centralized directional exhaust improves the overall temperature control stability of the computer room. The servo motor 14 drives the T-shaped rotating cylinder 20 to rotate at high speed, which synchronously drives the peripheral exhaust fan 13 to rotate in a circle, forming a continuous negative pressure suction effect inside the sealing cover 3. This creates a forced airflow from top to bottom in the inner cavity of the cabinet 1, while the preheated cold air at the bottom of the cabinet 1 flows upward through each layer. The switch removes heat, and the hot air enters the sealed cover 3 through the top exhaust port 11. It is then quickly discharged through the folded pipe 6 by the negative pressure suction of the exhaust fan 13. The top of the cabinet 1 is equipped with a temperature and humidity monitoring sensor to collect real-time temperature and humidity data inside the cabinet and transmit the monitoring signal to the control terminal to realize adaptive adjustment of the exhaust fan 13. This solves the problem that most existing switch cabinets used to improve the heat dissipation efficiency of switches adopt side wall openings and top open ventilation structures without sealed air collection and directional exhaust channels. The high-temperature exhaust gas generated by the switch is directly diffused and accumulated in the computer room and cannot be discharged in a concentrated manner. The simultaneous operation of multiple cabinets can easily cause the computer room to accumulate heat and the room temperature to rise continuously. The central air conditioning of the computer room alone is not enough to offset the heat dissipation of the equipment. The switch will be in a high-temperature environment for a long time, which will accelerate the aging of components, shorten its service life, and the computer room cooling energy consumption is high.
[0036] like Figure 1 , Figures 8 to 10 As shown, an umbrella-shaped gear disk 17 is rotatably connected to the inner cavity of the T-shaped rotating cylinder 20. The umbrella-shaped gear disk 17 is meshed with multiple bevel gears 18, and one end of each bevel gear 18 passes through the T-shaped rotating cylinder 20 and is fixedly connected to an adjusting blade 19. The bevel gear 18 is rotatably connected to the T-shaped rotating cylinder 20. A drive shaft 16 is fixedly connected to the lower end of the umbrella-shaped gear disk 17. A control motor is fixedly connected to one end of the drive shaft 16 to drive the drive shaft 16 to rotate the umbrella-shaped gear disk 17, which in turn meshes with the bevel gears 18 to drive the adjusting blades 19 to adjust the tilt angle. The air extraction efficiency can be adjusted according to the temperature and humidity inside the cabinet 1.
[0037] Specifically, when the temperature and humidity monitor detects that the temperature inside the cabinet is too high or that heat is accumulating, it controls the motor to drive the transmission shaft 16 to rotate, which in turn drives the bevel gear 17 to rotate synchronously. The bevel gear 17 meshes with all the bevel gears 18 on the outer periphery, which rotate synchronously in the same direction. The bevel gears 18 drive the outer adjusting blades 19 to deflect synchronously, increasing the tilt angle. When the exhaust fan 13 rotates, the blade's frontal area increases, the negative pressure suction volume increases, and the speed at which hot air is discharged from the cabinet is accelerated, enhancing heat dissipation efficiency. When it detects that the temperature inside the cabinet is too low or the humidity is too high, which may cause condensation, it controls the motor to drive the bevel gear 17 in the opposite direction, causing all the adjusting blades 19 to retract synchronously, reducing the tilt angle and lowering the effective ventilation of the exhaust fan 13. Air volume reduces airflow speed, prolongs the premixing and heat exchange time of hot and cold air, stabilizes the temperature and humidity range inside the cabinet, suppresses condensation from the source, and enables dynamic adaptive adjustment of exhaust efficiency based on real-time temperature and humidity inside the cabinet. This solves the problem that existing switch cabinets used to improve the heat dissipation efficiency of switches mostly rely on natural convection or fixed-speed exhaust modes for heat dissipation, and do not have a structure for real-time temperature and humidity monitoring and adaptive control. They cannot dynamically adjust the heat dissipation air volume according to the load of the equipment inside the cabinet and changes in ambient temperature and humidity. Continuous high-power exhaust under low temperature and low humidity conditions will waste energy, while insufficient exhaust air volume under high temperature and high humidity conditions will lead to untimely heat dissipation, heat accumulation and condensation inside the cabinet, and cause short circuit and shutdown failure of the switch.
[0038] like Figure 1 and Figure 12 As shown, a base 2 is fixedly connected to the lower end of the cabinet 1, and a lifting mechanism is provided in the inner cavity of the base 2. A sliding mesh plate 4 is fixedly connected to the lower end of the lifting mechanism, and universal wheels 22 are installed at the four corners of the lower end of the sliding mesh plate 4.
[0039] Specifically, during the transport of the entire unit, the lifting mechanism extends the sliding mesh plate 4 downwards, allowing the casters 22 to contact the ground and the base 2 to be lifted off the ground. The cabinet can be freely pushed to the designated location in the computer room. After positioning, the lifting mechanism retracts the sliding mesh plate 4, the base 2 lands on the ground to bear the weight, and the casters 22 are suspended in the air, ensuring the stability of the cabinet. The sliding mesh plate 4 has a hollow mesh structure, allowing cold air from the bottom of the computer room to pass through the mesh plate and enter the interior from the air inlet 9 at the bottom of the cabinet 1 without obstructing the airflow from the bottom.
[0040] Based on the above, it is important to note that the function of the semi-circular clamp in this embodiment is fundamentally different from that of the semi-circular clamp in the communication cabinet patch panel. The semi-circular clamp in the communication cabinet patch panel clamps the communication line using a first spring; its working state is static, meaning the semi-circular clamp remains stationary after clamping, and the communication line is fixed in a certain position. However, the semi-circular clamp in this embodiment, i.e., the threaded clamp 73 formed by two semi-circular clamps joined together, is dynamic. It can normally close and engage with the threaded rod 72 under the action of the compression spring 74 and a strong magnet (e.g., ...). Figure 4 As shown in the diagram, when the T-shaped insert 710 is wedged in, it overcomes the elastic force of the compression spring 74 and separates to both sides, causing the threads to disengage (as shown). Figure 5 As shown in the diagram, after the external force disappears, it automatically closes and resets under the action of the compression spring 74 and the strong magnet. In this invention, the semi-circular clamp is in a continuous state change, and its two states of closing and opening actively switch according to the adjustment requirements of the support platform 5, rather than maintaining a single closed clamping state as in the prior art. This transforms the semi-circular clamp from a passive fixing element into an active control element.
[0041] Working principle: During switch installation, the first spring 79 continuously pulls the T-shaped plug 710 backward, causing it to be completely retracted into the second T-shaped slide groove 76 without contacting the threaded clamp 73. The threaded clamp 73 remains engaged and locked, allowing the threaded rod 72 to adjust the shelf height normally. The switch is then installed onto the support platform 5 at the bottom of the cabinet 1. At this time, the threaded rod 72 drives the threaded clamp 73 to move the upper support platform 5 downward. The support platform 5 causes the push block 78 to move downward and abut against the top surface of the switch. Simultaneously, the push block 78 pushes the sliding frame 714 to slide towards the center of the second T-shaped slide groove 76. The two side blocks 713 simultaneously press against the tail of the T-shaped plug 710, causing the T-shaped plug 710 to extend forward against the pull of the first spring 79, forming an inclined wedge. The face is inserted between two semi-circular clamps, and the threaded clamp 73 is laterally opened. The thread and threaded rod 72 are separated, and the bearing platform 5 automatically releases the thread constraint. The height can be freely adjusted. After the switch is removed, the push block 78 loses the downward pressure load, the sliding frame 714 and the stop block 713 are reset, the T-shaped plug 710 has no lateral squeezing force, the first spring 79 rebounds and pulls the T-shaped plug 710 back, and the semi-circular clamps re-close and mesh under the action of the compression spring 74 and the strong magnet. This avoids the situation where the gap between the shelves of the traditional switch cabinet is not adjustable, the upper part is reserved with too much ineffective space when the low switch is placed, and the gap between the shelves is narrow when the high switch is placed. The equipment is tightly attached to the shelves on all four sides, the airflow channel is blocked, the working heat continues to accumulate, and the high temperature alarm of the equipment is easily triggered, which will cause the components to age faster. When the equipment is in normal operation without unlocking, the two side springs 74 continuously pre-tighten the two semi-circular clamps, ensuring that the threaded clamp 73 and the threaded rod 72 are tightly engaged throughout the entire process. The rotation of the threaded rod 72 can stably drive the bearing platform 5 to rise and fall synchronously, with high precision in adjusting the interlayer gap. When the sliding frame 714 pushes the T-shaped insert 710 to extend to the middle, the inclined arc surface of the T-shaped insert 710 weds between the two semi-circular clamps, opening the semi-circular clamps to both sides. The semi-circular clamps overcome the elastic force of the springs 74 and slide towards both ends of the first T-shaped slide groove 75. The thread and the threaded rod 72... Completely disengaged, the support platform 5 is no longer constrained by the threaded rod 72, allowing for quick manual lifting or lowering for height adjustments without disassembling any fasteners. When the switch is removed and the unlocking force disappears, the spring 74 elastically retracts, automatically pushing the two semi-circular clamps together to form the threaded clamp 73. Furthermore, the two semi-circular clamps are equipped with powerful magnets, which work together to quickly close them together to form the threaded clamp 73. The threads re-engage with the threaded rod 72, restoring rigid lifting transmission, thus meeting both precise fine-tuning and rapid loading and unloading needs.
