Description

Technical Field

[0001] This invention relates to the field of outdoor cabinet security protection technology, specifically to a heat-insulating and anti-condensation outdoor cabinet. Background Technology

[0002] Outdoor cabinets serve as the core installation and protection platform for outdoor electrical equipment, communication equipment, and control systems. Their primary function is to provide physical protection for internal equipment, isolating it from external elements such as wind, rain, dust, and insects, and maintaining a suitable internal operating environment. With the increasing demand for outdoor deployments in industries such as communications and power, outdoor cabinets are widely used in various complex environments, including urban fringe areas, rural areas, and mountainous regions. They must withstand long-term exposure to harsh conditions such as large diurnal temperature variations, drastic seasonal temperature fluctuations (summer temperatures can reach above 40℃, while winter temperatures can drop below -30℃), high humidity, rain, snow, fog, and frost.

[0003] Outdoor cabinets, as the core protective carriers for outdoor electrical equipment such as communication and power systems, must withstand the complex environmental effects of large temperature differences between day and night and high humidity for extended periods. They are prone to condensation due to factors such as the contact between high-temperature and high-humidity air inside and low-temperature surfaces, the contradiction between sealing and permeability, and fluctuations in equipment heating. Condensation adheres to the surfaces of electrical components such as circuit boards and terminals, reducing insulation performance and causing leakage and short circuits. It also corrodes metal structures, leading to decreased strength and equipment damage. Furthermore, it affects the detection accuracy and control stability of precision equipment such as sensors, causing equipment failure, performance degradation, shortened lifespan, and increased maintenance costs, seriously threatening the operational safety and stability of the equipment inside the cabinet. Summary of the Invention

[0004] The purpose of this invention is to provide a heat-insulating and anti-condensation outdoor cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-insulating and anti-condensation outdoor cabinet, comprising a cabinet body, a blower assembly for heat dissipation fixedly installed at the bottom of the inner cavity of the cabinet body, heat insulation assemblies for heat insulation of the cabinet body symmetrically arranged on both sides of the cabinet body, a drive assembly that can automatically open and close the heat insulation assembly to prevent condensation when the internal temperature of the cabinet body changes on one side of the heat insulation assembly, a blower assembly for temperature control of the heat insulation assembly symmetrically installed on both sides of the top of the cabinet body, and mounting openings on both sides of the cabinet body, the heat insulation assembly including a first mounting plate fixedly installed on one side of the mounting opening, a heat insulation groove opened on the side of the first mounting plate near the inside of the cabinet body, two identical heat insulation plates arranged inside the heat insulation groove, and a second mounting plate fixedly installed on the side of each of the two heat insulation plates near the inside of the cabinet body, the inner wall of the heat insulation groove being in contact with the surface of the adjacent second mounting plate.

[0006] With the above technical solution, when the internal temperature of the rack body rises, the drive component will automatically drive the heat insulation component to open due to the temperature change. The opening of the heat insulation component allows the lower external temperature to be transferred into the interior of the rack body. When the internal temperature of the rack body gradually decreases, the drive component will also gradually close the heat insulation component according to the temperature to prevent moisture from entering the interior of the rack body when the external temperature is low. The blowing component will continuously blow into the interior of the heat insulation component when the heat insulation component is closed, keeping the heat insulation component dry and preventing condensation from forming inside the rack body and on the heat insulation component.

[0007] Under normal use, both second mounting plates are located inside the heat insulation groove. Therefore, the two heat insulation plates fixedly installed on the second mounting plates are also located inside the heat insulation groove. Due to the restriction of the second mounting plates, the two heat insulation plates will be in contact with the inner wall of the heat insulation groove. Thus, the first mounting plate, the heat insulation plates, and the second mounting plates form a whole heat insulation layer that can effectively insulate the heat, thereby achieving heat insulation for the cabinet body.

[0008] Preferably, the cabinet body has support rods on both sides inside, and fixed plates are rotatably installed at both ends of the two support rods. Each fixed plate is fixedly installed on one side of the adjacent first mounting plate. Each second mounting plate has multiple first connecting blocks fixedly installed on the side near the support rod. Each first connecting block has a through-hole on one side, and each first connecting block is rotatably sleeved on the adjacent support rod through the through-hole.

[0009] With the above technical solution, when it is necessary to open the heat insulation component, simply rotate the first connecting block sleeved on the support rod. This will cause the first connecting block to drive the second mounting plate, which is fixedly installed thereto, to rotate around the adjacent support rod. The rotation of the second mounting plate will cause the heat insulation plate to rotate along with it, thus moving the heat insulation plate away from the inner wall of the heat insulation groove of the first mounting plate. When the heat insulation plate is away from the first mounting plate, the first mounting plate will lose the heat insulation effect provided by the heat insulation plate, allowing the external temperature to quickly enter the interior of the cabinet. Conversely, moving the heat insulation plate away from the first mounting plate will close both heat insulation plates. When the heat insulation plate is in contact with the inner wall of the heat insulation groove of the first mounting plate, the heat insulation groove of the first mounting plate will be filled, thus giving the first mounting plate a heat insulation effect. This opening and closing of the heat insulation plates can quickly change the internal temperature of the cabinet, thereby making the internal temperature of the cabinet consistent with the external temperature and reducing the generation of condensation.

[0010] Preferably, the drive assembly includes two second connecting blocks fixedly mounted on the side of the second mounting plate near the support rod. The two second connecting blocks are rotatably sleeved on the adjacent support rod. The two second connecting blocks are arranged vertically. The bottom end of the two second connecting blocks has a spirally arranged drive hole. A drive rod is inserted into the interior of each of the two drive holes. The drive rod is spirally arranged. A drive column is fixedly mounted inside the cabinet body. Two drive rings are slidably sleeved on the drive column. A third connecting block is fixedly mounted on one side of each of the two drive rings. The top of each of the two third connecting blocks is fixedly mounted to the bottom end of the adjacent drive rod.

[0011] With the above technical solution, when the drive ring slides on the drive column, the upward sliding of the drive ring will drive the third connecting block to move upward. The third connecting block will push the drive rod upward. Since the top of the drive rod is inserted into the opening of the drive hole, and both the drive rod and the drive hole are spirally arranged, when the drive rod moves upward, the spiral outer surface will contact and push the spiral inner wall of the drive hole. The inner wall of the drive hole being pushed will cause the second connecting block to rotate around the support rod. The rotation of the second connecting block will cause the second mounting plate fixed to it to also rotate around the support rod, thereby driving the heat insulation plate to move and completing the opening of the heat insulation plate.

[0012] When the drive ring slides down on the drive column, the drive ring, the third connecting block and the drive rod will move down together. This will cause the drive rod to push the inner wall of the drive hole in the opposite direction, so that the second connecting block, the second mounting plate and the heat insulation plate will rotate in the opposite direction around the support rod, thus completing the closure of the heat insulation plate.

[0013] Preferably, the top of the drive column is provided with a drive groove, a sealing plate is slidably disposed inside the drive groove, a push rod is fixedly installed at the top of the sealing plate, a drive plate is fixedly installed at the top of the push rod, and connecting plates are fixedly installed on both sides of the bottom end of the drive plate. The bottom end of one of the connecting plates extends downward and is fixedly installed with the drive ring located at the top, and the bottom end of the other connecting plate extends downward and passes through the drive ring located at the top and is fixedly installed with the drive ring located at the bottom. Paraffin wax is disposed inside the drive groove, and the sealing plate is located on top of the paraffin wax.

[0014] With the above technical solution, when the internal temperature of the cabinet body rises, the high temperature will melt the paraffin inside the drive column. After the paraffin melts, its volume will expand. The expansion of the paraffin will push the sealing plate upward. The upward movement of the sealing plate will cause the push rod to move upward, thereby causing the drive plate to move upward. This will cause the connecting plate to move upward, and the upward movement of the connecting plate will drive the drive ring fixed to it to move upward, thereby allowing the third connecting block to complete the upward movement of the drive rod.

[0015] When the temperature inside the cabinet body decreases, the paraffin inside the drive column cools down. After cooling, the paraffin shrinks in volume. Since the paraffin is sealed inside the drive groove of the drive column by the sealing plate, the shrinkage of the paraffin creates negative pressure, which drags the sealing plate downward. At this time, the sealing plate moves down, which in turn moves the push rod, drive plate, connecting plate and drive ring down. In this way, the third connecting block moves the drive rod down, allowing the drive rod to push the inner wall of the drive hole.

[0016] Preferably, the blowing assembly includes a collection block fixedly installed on the top of the inner cavity of the cabinet body. The bottom of the collection block has a gathering groove that penetrates itself. The top of the collection block is fixedly connected to an exhaust pipe. The exhaust pipe is square in shape. The exhaust end of the exhaust pipe passes through the cabinet body and the adjacent first mounting plate in sequence and extends into the interior of the heat insulation groove. One end of the exhaust pipe inside the heat insulation groove is located between the top of the heat insulation plate and the second mounting plate.

[0017] With the above technical solution, when the blower assembly blows air, the hotter air rises to the top of the inner cavity of the cabinet body. After the gas enters the top, it enters the collection groove of the collection block. Due to the continuous blowing of the blower assembly, the air below moves upward, allowing the hot air in the collection groove to move along the exhaust pipe. When the hot air enters the heat insulation groove along the exhaust pipe, it blows on the heat insulation board. The temperature of the heat insulation board and the second mounting plate will rise slightly and keep the surface dry, reducing the possibility of condensation on the surface of the heat insulation board and the second mounting plate.

[0018] Preferably, each of the two heat insulation plates has a plurality of first air passages arranged in an array on the side near the adjacent second mounting plate, and each of the two second mounting plates has a plurality of second air passages arranged in an array on the side near the adjacent heat insulation plate, and each first air passage is connected to an adjacent second air passage.

[0019] With the above technical solution, when the blower assembly blows air, the air entering the exhaust pipe will be discharged from the top of the heat insulation plate and the second mounting plate. The discharged air will enter the interior of the first air passage and the second air passage, and descend along the first air passage and the second air passage. This facilitates the overall blowing and drying of the heat insulation plate and the second mounting plate, and avoids the center of the heat insulation plate and the second mounting plate not being dried by the blowing.

[0020] Preferably, the bottom of the two first mounting plates is provided with a plurality of exhaust holes arranged in an array, and each exhaust hole is connected to an adjacent first vent hole and a second vent hole.

[0021] Through the above technical solution, the air entering the first and second vents will gradually descend and then be discharged from the exhaust port, allowing air to circulate.

[0022] Preferably, each of the two first mounting plates has a filter plate at its bottom, each of the exhaust holes is located above the adjacent filter plate, and each of the two filter plates has an "L"-shaped baffle at both ends. Both ends of each filter plate extend to the inner right angle of the adjacent baffle, and one end of each baffle is fixedly installed to the bottom of the adjacent first mounting plate.

[0023] The above technical solution allows for the filtration of air entering the cabinet body by installing a filter plate under the exhaust port. Since it works in conjunction with the baffle, it can be pulled out directly between the two baffles for cleaning or replacement. Installation is also simple: insert both ends into the right angle of the baffle and then slide it to the exhaust port.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. Adopting a paraffin thermal expansion and contraction driven structure, it can automatically control the opening and closing of the heat insulation components according to the temperature changes inside the cabinet without the need for an additional power source, realizing intelligent switching between heat insulation and heat dissipation, and adapting to complex outdoor temperature change environments. 2. The heat insulation component adopts a double-layer heat insulation board and mounting plate structure. When closed, it forms a sealed heat insulation layer with good heat insulation effect. When opened, the heat dissipation channel is unobstructed and the heat dissipation efficiency is high. 3. The blowing component works in conjunction with the air vent and exhaust vent to form a circulating airflow, continuously blowing and drying the heat insulation component, effectively preventing condensation and avoiding equipment damage due to condensation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 10 The present invention provides a technical solution: a heat-insulating and anti-condensation outdoor cabinet, including a cabinet body 1, a blower assembly 2 for heat dissipation is fixedly installed at the bottom of the inner cavity of the cabinet body 1, heat insulation components for heat insulation of the cabinet body 1 are symmetrically arranged on both sides of the cabinet body 1, a drive assembly is provided on one side of the heat insulation component that can automatically open and close the heat insulation component to prevent condensation when the internal temperature of the cabinet body 1 changes, and blowing components for temperature control of the heat insulation component are symmetrically installed on both sides of the top of the cabinet body 1.

[0029] When the internal temperature of the rack body 1 rises, the drive component will automatically activate the heat insulation component due to the temperature change. The opening of the heat insulation component allows the lower external temperature to enter the interior of the rack body 1. When the internal temperature of the rack body 1 gradually decreases, the drive component will gradually close the heat insulation component according to the temperature to prevent moisture from entering the interior of the rack body 1 when the external temperature is low. The blowing component will continuously blow on the interior of the heat insulation component when it is closed, keeping the heat insulation component dry and preventing condensation from forming inside the rack body 1 and on the heat insulation component.

[0030] The rack body 1 has mounting openings 6 on both sides. The heat insulation component includes a first mounting plate 301 fixedly installed on one side of the mounting opening 6. The first mounting plate 301 has a heat insulation groove 302 on the side near the inside of the rack body 1. The heat insulation groove 302 has two identical heat insulation plates 303 inside. The side of each heat insulation plate 303 near the inside of the rack body 1 is fixedly installed with a second mounting plate 304. The inner wall of the heat insulation groove 302 is in contact with the surface of the adjacent second mounting plate 304.

[0031] Under normal use, both second mounting plates 304 are located inside the heat insulation groove 302. Therefore, the two heat insulation plates 303 fixedly installed on the second mounting plates 304 are also located inside the heat insulation groove 302. Due to the restriction of the second mounting plates 304, the two heat insulation plates 303 will fit against the inner wall of the heat insulation groove 302. Thus, the first mounting plate 301, the heat insulation plate 303 and the second mounting plate 304 form a whole heat insulation layer that can effectively insulate the heat, so as to achieve heat insulation for the cabinet body 1.

[0032] The cabinet body 1 has support rods 7 on both sides inside. The two ends of the support rods 7 are rotatably mounted with fixing plates 8. Each fixing plate 8 is fixedly mounted to one side of the adjacent first mounting plate 301. Each second mounting plate 304 has multiple first connecting blocks 9 fixedly mounted on the side near the support rods 7. Each first connecting block 9 has a through-hole on one side. Each first connecting block 9 is rotatably sleeved on the adjacent support rod 7 through the through-hole.

[0033] When the heat insulation assembly needs to be opened, simply rotate the first connecting block 9, which is sleeved on the support rod 7. This will cause the first connecting block 9 to drive the second mounting plate 304, which is fixedly installed thereto, to rotate around the adjacent support rod 7. The rotation of the second mounting plate 304 will cause the heat insulation plate 303 to rotate along with it, thereby moving the heat insulation plate 303 away from the inner wall of the heat insulation groove 302 of the first mounting plate 301. Once the heat insulation plate 303 is away from the first mounting plate 301, the first mounting plate 301 will lose the support of the heat insulation plate 303. The resulting heat insulation effect allows external temperature to quickly enter the interior of the cabinet body 1. Conversely, closing the two heat insulation plates 303 closes the heat insulation plates 303. When the heat insulation plates 303 are in contact with the inner wall of the heat insulation groove 302 of the first mounting plate 301, the heat insulation groove 302 of the first mounting plate 301 will be filled, thus giving the first mounting plate 301 a heat insulation effect. This opening and closing of the heat insulation plates 303 can quickly change the internal temperature of the cabinet body 1, thereby making the internal temperature of the cabinet body 1 the same as the external temperature and reducing the generation of condensation.

[0034] The drive assembly includes two second connecting blocks 401 fixedly installed on the side of the second mounting plate 304 near the support rod 7. The two second connecting blocks 401 are rotatably sleeved on the adjacent support rod 7. The two second connecting blocks 401 are arranged vertically. The bottom end of the two second connecting blocks 401 is provided with a spirally arranged drive hole 402. A drive rod 403 is inserted into the interior of the two drive holes 402. The drive rod 403 is spirally arranged. A drive column 404 is fixedly installed inside the cabinet body 1. Two drive rings 405 are slidably sleeved on the drive column 404. A third connecting block 406 is fixedly installed on one side of each of the two drive rings 405. The top of each of the two third connecting blocks 406 is fixedly installed to the bottom end of the adjacent drive rod 403.

[0035] When the drive ring 405 slides on the drive column 404, the upward sliding of the drive ring 405 will drive the third connecting block 406 to move upward. The third connecting block 406 will push the drive rod 403 upward. Since the top of the drive rod 403 is inserted into the opening of the drive hole 402, and both the drive rod 403 and the drive hole 402 are spirally arranged, when the drive rod 403 moves upward, the spiral outer surface will contact and push the spiral inner wall of the drive hole 402. The inner wall of the drive hole 402 being pushed will cause the second connecting block 401 to rotate around the support rod 7. The rotation of the second connecting block 401 will also cause the second mounting plate 304, which is fixedly installed thereto, to rotate around the support rod 7, thereby driving the heat insulation plate 303 to move and completing the opening of the heat insulation plate 303.

[0036] When the drive ring 405 slides downward on the drive column 404, the drive ring 405, the third connecting block 406 and the drive rod 403 will move downward together. In this way, the drive rod 403 will push the inner wall of the drive hole 402 in the opposite direction, so that the second connecting block 401, the second mounting plate 304 and the heat insulation plate 303 will rotate in the opposite direction around the support rod 7, thus completing the closure of the heat insulation plate 303.

[0037] A drive groove 10 is provided at the top of the drive column 404. A sealing plate 11 is slidably arranged inside the drive groove 10. A push rod 12 is fixedly installed at the top of the sealing plate 11. A drive plate 13 is fixedly installed at the top of the push rod 12. Connecting plates 14 are fixedly installed on both sides of the bottom end of the drive plate 13. The bottom end of one connecting plate 14 extends downward and is fixedly installed with the drive ring 405 located at the top. The bottom end of the other connecting plate 14 extends downward and passes through the drive ring 405 located at the top and is fixedly installed with the drive ring 405 located at the bottom. Paraffin wax 15 is provided inside the drive groove 10. The sealing plate 11 is located on top of the paraffin wax 15.

[0038] When the internal temperature of the cabinet body 1 rises, the high temperature will melt the paraffin 15 inside the drive column 404. After the paraffin 15 melts, its volume will expand. The expansion of the paraffin 15 will push the sealing plate 11 upward. The upward movement of the sealing plate 11 will cause the push rod 12 to move upward, thereby causing the drive plate 13 to move upward, which will move the connecting plate 14 upward. The upward movement of the connecting plate 14 will drive the drive ring 405 fixedly installed thereto to move upward, thereby allowing the third connecting block 406 to complete the upward movement of the drive rod 403.

[0039] When the temperature inside the cabinet body 1 decreases, the paraffin wax 15 inside the drive column 404 will cool down. After cooling down, the volume of the paraffin wax 15 will shrink. Since the paraffin wax 15 is sealed inside the drive groove 10 of the drive column 404 by the sealing plate 11, when the volume of the paraffin wax 15 shrinks, a negative pressure will be generated, which will drag the sealing plate 11 downward. At this time, the sealing plate 11 will move down. The downward movement of the sealing plate 11 will also move the push rod 12, drive plate 13, connecting plate 14 and drive ring 405 down. In this way, the third connecting block 406 will move the drive rod 403 down, allowing the drive rod 403 to push the inner wall of the drive hole 402.

[0040] The blowing assembly includes a collection block 501 fixedly installed on the top of the inner cavity of the cabinet body 1. The bottom of the collection block 501 has a gathering groove that passes through it. The top of the collection block 501 is fixedly connected to an exhaust pipe 502. The exhaust pipe 502 is square in shape. The exhaust end of the exhaust pipe 502 passes through the cabinet body 1 and the adjacent first mounting plate 301 in sequence and extends into the interior of the heat insulation groove 302. One end of the exhaust pipe 502 located inside the heat insulation groove 302 is located between the top of the heat insulation plate 303 and the second mounting plate 304.

[0041] When the blower assembly 2 blows air, the hotter air rises to the top of the inner cavity of the cabinet body 1. After the gas enters the top, it enters the gathering groove of the collection block 501. Due to the continuous blowing of the blower assembly 2, the air below moves upward, causing the hot air inside the gathering groove to move along the exhaust pipe 502. When the hot air enters the heat insulation groove 302 along the exhaust pipe 502, it blows on the heat insulation plate 303. The temperature of the heat insulation plate 303 and the second mounting plate 304 will rise slightly and keep the surface dry, reducing the possibility of condensation on the surface of the heat insulation plate 303 and the second mounting plate 304.

[0042] Each of the two heat insulation plates 303 has a plurality of first air passage holes 503 arranged in an array on the side near the adjacent second mounting plate 304, and each of the two second mounting plates 304 has a plurality of second air passage holes 504 arranged in an array on the side near the adjacent heat insulation plate 303, and each first air passage hole 503 is connected to the adjacent second air passage hole 504.

[0043] When the blower assembly 2 blows air, the air entering the exhaust pipe 502 will be discharged from the top of the heat insulation plate 303 and the second mounting plate 304. The discharged air will enter the interior of the first air passage 503 and the second air passage 504, and descend along the first air passage 503 and the second air passage 504. This facilitates the overall blowing and drying of the heat insulation plate 303 and the second mounting plate 304, and avoids the center of the heat insulation plate 303 and the second mounting plate 304 not being dried by the blowing.

[0044] The bottom of the two first mounting plates 301 is provided with a plurality of exhaust holes 16 arranged in an array, and each exhaust hole 16 is connected to the adjacent first vent hole 503 and second vent hole 504.

[0045] The air entering the first vent 503 and the second vent 504 will gradually descend and then be discharged from the exhaust port 16, allowing air to circulate.

[0046] The bottom of each of the two first mounting plates 301 is provided with a filter plate 17, and each exhaust hole 16 is located above the adjacent filter plate 17. Both ends of the two filter plates 17 are provided with baffles 18 arranged in an "L" shape. Both ends of each filter plate 17 extend to the inner right angle of the adjacent baffle 18, and one end of each baffle 18 is fixedly installed to the bottom of the adjacent first mounting plate 301.

[0047] Installing a filter plate 17 under the exhaust port 16 can filter the air entering the cabinet body 1. Since it works in conjunction with the baffle 18, it can be pulled out directly between the two baffles 18 for cleaning or replacement. Installation is also simple: insert both ends into the right angle of the baffle 18 and then slide it to the exhaust port 16.

[0048] Working principle: 1. Under heat insulation conditions, the internal temperature of the cabinet is normal or slightly low. In the initial state, the internal temperature of the cabinet body 1 is within the normal range or slightly low. The paraffin 15 inside the drive column 404 is solid and stable in volume. The sealing plate 11 is held in the initial position in the drive groove 10 by the support of the paraffin 15. At this time, the drive plate 13 drives the two drive rings 405 to the low position on the drive column 404 through the connecting plate 14. The third connecting block 406 drives the drive rod 403 to the low position. The drive rod 403 is screwed into the opening of the drive hole 402 of the second connecting block 401, so that the second connecting block 401 remains stationary. Then, the second mounting plate 304 pushes the heat insulation plate 303 to adhere to the inner wall of the heat insulation groove 302 of the first mounting plate 301. The first mounting plate 301, the heat insulation plate 303 and the second mounting plate 304 together form a sealed heat insulation layer, which effectively blocks the external low temperature from being transmitted to the inside of the cabinet body 1 and prevents the internal temperature of the cabinet from being too low and causing condensation.

[0049] Meanwhile, the blower assembly 2 continues to operate, blowing air into the cabinet body 1 for heat dissipation. After the airflow rises to the top inside the cabinet, it enters the gathering groove of the collection block 501. Under the continuous air pressure of the blower assembly 2, the airflow is transported to the interior of the heat insulation groove 302 through the exhaust pipe 502 and blown out from the gap between the top of the heat insulation plate 303 and the second mounting plate 304. Part of the blown airflow directly blows onto the surface of the heat insulation plate 303 and the second mounting plate 304, increasing their surface temperature and keeping them dry. Another part of the airflow passes through the second air passage 504 on the second mounting plate 304 and the first air passage 503 on the heat insulation plate 303, flows through the entire heat insulation plate 303 and the second mounting plate 304, and is discharged from the exhaust hole 16 at the bottom of the first mounting plate 301 to the outside of the cabinet, forming a complete airflow cycle. During this process, the filter plate 17 filters the air entering the cabinet through the exhaust hole 16 to prevent dust and impurities from entering.

[0050] II. Heat Dissipation Status: Rising Internal Temperature of the Server Rack When the internal equipment of the cabinet body 1 generates heat during operation, causing the internal temperature to rise, the high temperature is transferred to the drive column 404, causing the paraffin wax 15 inside the drive groove 10 to melt. After the paraffin wax 15 melts, it expands in volume and pushes the sealing plate 11 upward to slide along the inner wall of the drive groove 10. The upward movement of the sealing plate 11 causes the push rod 12 to move upward synchronously, and the drive plate 13 at the top of the push rod 12 moves upward accordingly. The drive plate 13 drives the two drive rings 405 to slide upward along the drive column 404 through the connecting plates 14 on both sides. The upward movement of the drive rings 405 causes the third connecting block 406 on one side to move upward synchronously, and the drive rod 403 at the top of the third connecting block 406 moves upward accordingly.

[0051] Since the drive rod 403 is spiral-shaped and is inserted into the spiral drive hole 402 at the bottom of the second connecting block 401, when the drive rod 403 moves upward, its spiral outer surface interacts with the spiral inner wall of the drive hole 402, generating a circumferential driving force, which pushes the second connecting block 401 to rotate around the support rod 7. The rotation of the second connecting block 401 drives the second mounting plate 304, which is fixedly connected to it, to rotate synchronously around the support rod 7. The first connecting block 9 on one side of the second mounting plate 304 rotates synchronously along the support rod 7, ensuring that the second mounting plate 304 rotates smoothly. The rotation of the second mounting plate 304 drives the heat insulation plate 303 on the other side to move away from the inner wall of the heat insulation groove 302 of the first mounting plate 301, so that the heat insulation groove 302 is in an open state. The lower temperature air outside quickly enters the cabinet body 1 through the mounting port 6 and the open heat insulation groove 302, and exchanges heat with the hot air inside the cabinet to achieve efficient heat dissipation.

[0052] III. Temperature reduction inside the rack after resetting to thermal insulation status As the internal temperature of the cabinet body 1 gradually decreases, the temperature of the drive column 404 decreases synchronously, and the paraffin wax 15 inside the drive groove 10 cools and solidifies, shrinking in volume. Since the paraffin wax 15 is sealed inside the drive groove 10 by the sealing plate 11, the shrinkage of the paraffin wax 15 generates negative pressure, pulling the sealing plate 11 downward and sliding it in the opposite direction along the inner wall of the drive groove 10. The downward movement of the sealing plate 11 causes the push rod 12, drive plate 13, and connecting plate 14 to move downward synchronously, and the connecting plate 14 causes the drive ring 405 to slide downward along the drive column 404. The drive ring 405 moves down, causing the third connecting block 406 and the drive rod 403 to move down synchronously. The drive rod 403 generates a reverse circumferential driving force on the inner wall of the drive hole 402, pushing the second connecting block 401 to rotate in the opposite direction around the support rod 7. The reverse rotation of the second connecting block 401 causes the second mounting plate 304 and the heat insulation plate 303 to rotate in the opposite direction synchronously until the heat insulation plate 303 is re-attached to the inner wall of the heat insulation groove 302. The heat insulation component is closed, the heat insulation state is restored, and external moisture is prevented from entering the cabinet and causing condensation.

[0053] Throughout the process, the blowing component 2 remains operational, continuously blowing on the insulation component to ensure that the surfaces of the insulation plate 303 and the second mounting plate 304 are dry, fundamentally preventing condensation. At the same time, it enables intelligent switching between insulation and heat dissipation, ensuring stable operation of the equipment inside the cabinet in complex outdoor environments.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
