Description

Technical Field

[0001] This invention relates to the field of distribution box technology, specifically a combined low-voltage integrated distribution box. Background Technology

[0002] As a core power distribution device at the end of urban and rural power distribution networks, factories, communities, and outdoor transformer substations in the smart grid, the combined low-voltage integrated distribution box integrates functions such as incoming line protection, power metering, reactive power compensation, leakage protection, and branch power supply. It is widely used in rural power grid transformation, industrial and commercial power distribution, and distributed photovoltaic power supply scenarios. Patent application CN224249159U includes a distribution box body with a rainproof cover fixedly connected to its top. A heat dissipation assembly is installed inside the distribution box body, comprising louvers that open and close. The outer wall of the louvers is fixedly connected to the inside of the distribution box body. A connecting pipe is fixedly connected inside the distribution box body, with a miniature fan fixedly connected to one end of the connecting pipe. A protective cover is fixedly connected to one side of the miniature fan, and a baffle ring is fixedly connected to the inner wall of the connecting pipe. A storage and organization assembly is also installed inside the distribution box body. This design utilizes a miniature fan to drive airflow, thereby efficiently dissipating heat from the electronic components inside the distribution box body. This achieves high-efficiency heat dissipation, solving the problem of poor heat dissipation in traditional distribution boxes leading to easy damage to electrical components and unstable operation, thus improving the efficiency of continuous and stable operation of the distribution box.

[0003] In the aforementioned patent, the low-voltage integrated distribution box needs to dissipate heat through ventilation during operation. However, conventional heat dissipation structures often directly introduce outside air. In a hot, humid, and dusty environment, the hot and humid airflow containing a large amount of water vapor and suspended particles continuously enters the box. When it comes into contact with the surface of the metal components with a lower temperature, it is very easy to reach the dew point and condense. At the same time, the accumulation of dust can easily lead to a decrease in insulation strength, creepage, and local overheating, which seriously threaten the safe and stable operation of the equipment. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a combined low-voltage integrated distribution box to solve the problems mentioned in the background.

Of the four perforated plates, the first and third perforated plates closest to the grooves are connected to a U-shaped rod. A first spring is fixed between one side of the U-shaped rod and the side wall of the connecting shell. An extension rod is fixedly connected to the end of the U-shaped rod away from the groove. A motor is fixedly installed on one side of the connecting shell. The output end of the motor is connected to a cam, and the cam cooperates with the extension rod. Two fixed elongated rods are fixedly disposed on the side wall of the connecting shell. Each fixed elongated rod has a rotatable connecting rod. Each connecting rod is connected to two adjacent slide rods via a movable assembly.

[0009] Preferably, the movable component includes two limiting grooves formed on each connecting rod, and the two limiting grooves on each connecting rod are symmetrical. Each sliding rod is fixedly provided with a fixing rod, and each fixing rod is movably disposed in the limiting groove closest to it.

[0010] Preferably, the circulation assembly includes a fixed box fixed to one side of the connecting shell. The side wall of the fixed box is fixed with four U-shaped blocks, each U-shaped block being hollow. The fixed box has eight through slots, arranged in pairs. The two through slots in each pair are staggered vertically and communicate with the corresponding U-shaped blocks. The lower input end of each serpentine tube is inserted into the lower corresponding through slot, and the upper output end of each serpentine tube is inserted into the upper corresponding through slot. The two lower U-shaped blocks are connected to the output ends of the inlet pipe, and the two upper U-shaped blocks are connected to the input ends of the outlet pipe.

[0011] Preferably, the input ends of the two water inlet pipes both pass through the water tank and are connected to the output pipe, and the other end of the output pipe is connected to the water pump.

[0012] Preferably, the outlet end of the water pipe extends into the water tank through a groove, and the portion of each water pipe located in the groove is a continuous S-bend, with both water pipes located on one side of the partition plate.

[0013] Preferably, the shielding assembly includes two fixing plates fixed on each serpentine tube and close to the inlet and outlet ends, and each through groove is provided with a sliding groove, and each fixing plate is slidably disposed in its corresponding sliding groove.

[0014] Preferably, the heat dissipation assembly includes a protective shell fixed to the bottom of the water tank, a heat sink installed inside the protective shell with its top surface in contact with the bottom surface of the water tank, a fixing frame fixed to the bottom surface of the inner wall of the water tank, a rotating wheel rotatably mounted on the fixing frame, and multiple sets of stirring blades arrayed on the outer surface of the rotating wheel, with one of the water outlet pipes having its output end located above and at a certain distance from one of the sets of stirring blades.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention significantly reduces the moisture content of the air entering the distribution box by combining condensation dehumidification with airflow mixing. When the distribution box is working, hot and humid external air is drawn in and passes through multiple perforated plates kept at a low temperature by circulating cooling water. Since the plate surface temperature is lower than the air dew point, water vapor quickly condenses into water droplets and separates from the air, greatly reducing the absolute moisture content of the air. Subsequently, the deeply dehumidified low-temperature clean air is divided into two paths by a partition plate. One path is kept at a low temperature as a bypass cold air, while the other path is heated by circulating hot water to become a high-temperature dry airflow. The two paths are fully mixed in a circular groove, and temperature neutralization is achieved through hot and cold mixing. This delivers clean air with a temperature similar to the environment but with a significantly reduced absolute moisture content into the distribution box. The delivered gas not only has a temperature close to ambient temperature but also a moisture content far lower than the original air, eliminating the hidden danger of internal condensation caused by temperature differences. At the same time, it takes into account the heat dissipation requirements of the equipment and ensures the safe operation of electrical equipment in humid environments.

[0016] 2. This invention achieves dust reduction through the formation of condensation. During the process of forming a condensate film on the surface of the perforated plate, fine dust in the airflow is effectively adsorbed and wrapped by the water film. The condensate and dust-laden wastewater flow downwards along the plate surface and are discharged into a water tank for temporary storage through a connecting channel, thus preventing dust from accumulating inside the distribution box. At the same time, the drive component drives the four perforated plates to move laterally and crosswise. Combined with the collision structure and spring system at the bottom, high-frequency micro-vibration is generated, which can shake off dust and residual water droplets on the plate surface in real time. This design reduces the dust in the gas entering the distribution box, significantly reducing maintenance costs. Even in outdoor or industrial environments with a large amount of dust, it can still ensure that the air supplied to the distribution box is highly clean.

[0017] 3. This invention achieves dual utilization of cold and heat by combining a serpentine tube and a circulation component. The serpentine tube on the back of the perforated plate absorbs heat from the humid air, causing it to condense, thus achieving efficient utilization of cold energy. The heated water is not directly discharged but is transported to a continuous S-shaped pipe in the groove, which acts as a heat source to heat the bypass airflow on one side, generating high-temperature, low-humidity dry air. This achieves efficient recovery and reuse of heat energy. The warm water after heat exchange is sent back to the water tank, while the impact agitator drives the rotor to rotate, accelerating the evaporation and heat dissipation of the water surface. Combined with the cooling fins at the bottom, this completes the self-cooling cycle of the water, greatly improving the overall energy utilization efficiency, reducing the consumption of external cooling resources, and lowering long-term operating costs.

[0020] Please see Figures 1 to 14This invention provides a technical solution: a combined low-voltage integrated distribution box, including a distribution box body 10, a connecting shell 20 fixed to the rear end of the distribution box body 10, an air inlet pipe 21 fixedly connected to the other end of the connecting shell 20, a filter screen 22 fixedly installed inside the air inlet pipe 21, a groove 23 opened on the connecting shell 20 facing the air inlet pipe 21, four mounting slots 24 vertically arranged in sequence in the groove 23, two sliders 27 movably installed in each mounting slot 24, the tops of the two sliders 27 located in the same mounting slot 24 are jointly fixedly connected to a perforated plate 25, and multiple communicating slots 44 are opened through each mounting slot 24. The plate 25 furthest from the air intake pipe 21 has a fan 28 fixedly installed behind it. A partition plate 46 is fixedly installed at the middle position of the rear end of the inner wall of the groove 23. A circular groove 29 is opened at the end of the groove 23. Two exhaust pipes 47 extending into the circular groove 29 are fixedly installed in the groove 23, and the two exhaust pipes 47 are respectively located on both sides of the partition plate 46. An exhaust port 11 is opened on one side of the power distribution box body 10, and a one-way valve is installed in the exhaust port 11. A vibration component that cooperates with the perforated plate 25 is installed in the mounting groove 24. The perforated plate 25 is driven to move laterally and crosswise by a drive component. A heat conduction component is provided on the back of each perforated plate 25.

[0021] In practice, when the distribution box is working, the fan 28 starts. Under the suction of the fan 28, external air enters through the intake pipe 21 and is first coarsely filtered by the filter screen 22. After entering the groove 23 of the connecting shell 20, the airflow passes through the perforated plates 25 in the four mounting slots 24 in sequence, and is then divided into left and right paths by the partition plate 46. The low-temperature clean air, after being dehumidified and dust-reduced by the perforated plate 25, enters the rear section of the groove 23 and is divided into two airflows by the partition plate 46. One of the airflows is discharged through the exhaust pipe 47 located on one side of the partition plate 46, serving as a low-temperature clean airflow. The bypass airflow is cool and dry, while the other airflow is retained in the groove 23 and heated to form a dry airflow that is hot and dry. It is then discharged through the exhaust pipe 47 on the other side of the partition plate 46. The two airflows converge in the circular groove 29 and achieve temperature complementarity through mixing. The high temperature of the bypass cold air is neutralized by the hot air, and finally air with a temperature close to the ambient temperature and a reduced absolute humidity is formed. This air is sent into the distribution box body 10 by the fan 28, which simultaneously meets the requirements of anti-condensation and equipment heat dissipation. Excess gas in the distribution box body 10 is discharged through the one-way valve of the exhaust port 11.

[0022] As a further embodiment of the present invention, the heat-conducting component includes a serpentine groove 26 formed on the back of each perforated plate 25, and a serpentine tube 50 is fixedly installed in the serpentine groove 26. Water flows inside the serpentine tube 50 through a circulation component at both ends.

[0023] In practice, the serpentine tube 50 fixedly installed in the serpentine groove 26 on the back of the perforated plate 25 is filled with circulating cooling water, which keeps the surface of the perforated plate 25 at a low temperature. When hot and humid air flows over the plate surface, the water vapor condenses into water droplets when it encounters the condensation. At the same time, the condensate forms a water film on the plate surface, adsorbing and capturing fine dust in the air. The condensate and dust-laden wastewater flow down the surface of the perforated plate 25 and are discharged into the water tank 45 for temporary storage through the connecting groove 44 at the bottom of the mounting groove 24. The water inside the serpentine tube 50 is kept flowing continuously through the circulation components at both ends, ensuring that the plate surface is kept at a low temperature.

[0024] As a further embodiment of the present invention, the vibration assembly includes three first triangular blocks 42 fixedly disposed at the bottom of each group of perforated plates 25, two second triangular blocks 43 that cooperate with the first triangular blocks 42 are fixedly disposed on the bottom of the inner wall of each mounting groove 24, a crossbar 40 is slidably disposed in each mounting groove 24, and three second springs 41 are fixedly disposed at the top of the crossbar 40, with the other end of each second spring 41 fixedly connected to the top of the inner wall of the mounting groove 24.

[0025] In practice, when the drive assembly moves the perforated plate 25, the three first triangular blocks 42 at the bottom of each perforated plate 25 periodically collide with the two second triangular blocks 43 fixedly installed on the bottom of the inner wall of each mounting groove 24. At the same time, under the elastic action of the crossbar 40 slidably installed in each mounting groove 24 and the three second springs 41 fixedly installed at the top of the crossbar 40, the other end of the second spring 41 is fixedly connected to the top of the inner wall of the mounting groove 24, so that each perforated plate 25 generates regular high-frequency micro-vibration, which promptly shakes off the dust and water droplets on the plate surface to prevent blockage. The sewage falls into the water tank 45 through the connecting groove 44.

[0026] As a further embodiment of the present invention, the driving assembly includes a first elongated groove 30 formed on one side of each perforated plate 25 and on one side of a slider 27 fixed below it. The connecting shell 20 has four second elongated grooves 31 corresponding to the four first elongated grooves 30. A sliding rod 32 is slidably disposed within the first elongated groove 30. The sliding rod 32 slides within the second elongated grooves 31 and extends to the outside of the connecting shell 20. Among the four perforated plates 25, the first and third perforated plates 25 closest to the groove 23 are jointly connected to a U-shaped rod 35. A first spring 36 is fixed between one side of the U-shaped rod 35 and the side wall of the connecting shell 20. An extension rod 37 is fixedly connected to the end of the U-shaped rod 35 away from the groove 23. A motor 38 is fixedly installed on one side of the connecting shell 20. The output end of the motor 38 is connected to a cam 39, and the cam 39 cooperates with the extension rod 37. Two fixed long rods 33 are fixedly provided on the side wall of the connecting shell 20. A connecting rod 34 is rotatably provided on each fixed long rod 33. Each connecting rod 34 is connected to two adjacent sliding rods 32 through a movable component.

[0027] In specific implementation, motor 38 drives cam 39 to rotate. Cam 39 cooperates with extension rod 37 to push U-shaped rod 35. U-shaped rod 35 drives the first and third perforated plates 25 connected to it near groove 23 to move laterally. When each perforated plate 25 moves, a first long groove 30 is opened on one side of each perforated plate 25 and on the side of the slider 27 fixed below it, and four second long grooves 31 are opened on one side of the connecting shell 20 to provide sliding space for slide rod 32. Slide rod 32 slides in the first long groove 30 and the second long groove 31 and extends to the outside of connecting shell 20. A first spring 36 fixed between one side of U-shaped rod 35 and the side wall of connecting shell 20 provides a restoring force. A connecting rod 34 is rotatably provided on each of the two fixed long rods 33 fixed on the side wall of connecting shell 20. Each connecting rod 34 is connected to two adjacent slide rods 32 through a movable component to transmit the motion to other perforated plates 25.

[0028] As a further embodiment of the present invention, the movable component includes two limiting grooves 340 formed on each connecting rod 34, and the two limiting grooves 340 on each connecting rod 34 are symmetrical. Each sliding rod 32 is fixedly provided with a fixing rod 341, and each fixing rod 341 is movably disposed in the limiting groove 340 closest to it.

[0029] In specific implementation, when the U-shaped rod 35 drives the first and third perforated plates 25 to move, the fixed rod 341 on the slide rod 32 connected to the two perforated plates 25 slides in the limiting groove 340 of the corresponding connecting rod 34, pushing the connecting rod 34 to rotate around the fixed long rod 33. Each connecting rod 34 has two symmetrical limiting grooves 340. The limiting groove 340 at the other end of the connecting rod 34 drives the fixed rod 341 on the slide rod 32 connected to the second and fourth perforated plates 25 to move, thereby driving the second and fourth perforated plates 25 to move in opposite directions, realizing the lateral cross movement of the four perforated plates 25.

[0030] As a further embodiment of the present invention, the circulation component includes a fixed box 51 fixed to one side of the connecting shell 20. Four U-shaped blocks 52 are fixedly provided on the side wall of the fixed box 51. The U-shaped blocks 52 are hollow. Eight through slots 53 are provided on the fixed box 51. The through slots 53 are arranged in pairs. The two through slots 53 in each pair are staggered and connected to the corresponding U-shaped blocks 52. The lower input end of each serpentine tube 50 is inserted into the lower corresponding through slot 53. The upper output end of each serpentine tube 50 is inserted into the upper corresponding through slot 53. The two lower U-shaped blocks 52 are connected to the output end of the water inlet pipe 56, and the two upper U-shaped blocks 52 are connected to the input end of the water outlet pipe 59. The fixed box 51 is provided with a shielding component that cooperates with the serpentine tube 50. A water tank 45 is fixedly provided at the bottom of the connecting shell 20 and corresponds to the connecting slot 44. A heat dissipation component is provided below the water tank 45.

[0031] In specific implementation, four hollow U-shaped blocks 52 are fixedly installed on the side wall of the fixed box 51 fixed to one side of the connecting shell 20. The fixed box 51 has eight through slots 53, which are arranged in pairs. The two through slots 53 in each pair are staggered and connected to the corresponding U-shaped blocks 52. The water pump 58 sends the water in the water tank 45 through the output pipe 57 and the inlet pipe 56 into the two U-shaped blocks 52 located below, and then distributes it to each serpentine pipe 50 through the corresponding through slots 53. The lower input end of each serpentine pipe 50 is inserted into the lower corresponding through slot 53. Cooling water enters the input end of each serpentine tube 50 through the lower through groove 53. After absorbing heat from the perforated plate 25, it enters the upper through groove 53 from the output end and flows into the two upper U-shaped blocks 52. The two upper U-shaped blocks 52 are respectively connected to the input end of the water outlet pipe 59. Hot water is output through the two water outlet pipes 59. The fixed box 51 is equipped with a shielding component that cooperates with the serpentine tube 50 to keep it sealed when the serpentine tube 50 moves. The bottom end of the connecting shell 20 is fixed with a water tank 45, which corresponds to the connecting groove 44 and is used to receive condensate and dusty sewage.

[0032] As a further embodiment of the present invention, the input ends of the two water inlet pipes 56 pass through the water tank 45 and are connected to the output pipe 57. The other end of the output pipe 57 is connected to the water pump 58.

[0033] In practice, the input ends of the two inlet pipes 56 pass through the water tank 45 and are connected to an output pipe 57. The other end of the output pipe 57 is connected to the water pump 58. The water pump 58 draws cooling water from the water tank 45 and distributes it through the output pipe 57 to the two inlet pipes 56, which are then sent into the two U-shaped blocks 52 below the side wall of the fixed box 51 to provide continuous circulating cooling water for the serpentine pipe 50.

[0034] As a further embodiment of the present invention, the output end of the water outlet pipe 59 extends into the water tank 45 through the groove 23, and the portion of each water outlet pipe 59 located in the groove 23 is in a continuous S-shape, and both water outlet pipes 59 are located on one side of the partition plate 46.

[0035] In practice, the output ends of the two water outlet pipes 59 extend into the water tank 45 through the groove 23. The portion of each water outlet pipe 59 located in the groove 23 is in a continuous S-shape. Both water outlet pipes 59 are located on one side of the partition plate 46. When the hot water flowing out of the serpentine pipe 50 flows back through the water outlet pipe 59, the continuous S-shape portion in the groove 23 increases the heat exchange area and contact time with the airflow stagnating on one side of the partition plate 46, thus fully heating the airflow on that side and forming a high-temperature, low-humidity dry airflow. The warm water after heat exchange is finally discharged into the water tank 45.

[0036] As a further embodiment of the present invention, the shielding assembly includes two fixing plates 54 fixed on each serpentine tube 50 and close to the water inlet and water outlet, and each through groove 53 is provided with a sliding groove 55, and each fixing plate 54 is slidably disposed in the corresponding sliding groove 55.

[0037] In specific implementation, when the serpentine tube 50 moves laterally and crosswise with the perforated plate 25, two fixed plates 54 fixed on each serpentine tube 50 and close to the inlet and outlet ends slide in the sliding grooves 55 opened in the corresponding through grooves 53. Each fixed plate 54 is slidably set in its corresponding sliding groove 55. The sliding stroke of the fixed plate 54 in the sliding groove 55 is matched with the lateral movement stroke of the perforated plate 25 to ensure that the connection between the serpentine tube 50 and the U-shaped block 52 is maintained during the movement, preventing the pipeline from falling off or leaking, and achieving dynamic sealing.

[0038] As a further embodiment of the present invention, the heat dissipation assembly includes a protective shell 60 fixed to the bottom of the water tank 45, a heat sink 61 installed inside the protective shell 60, and the top surface of the heat sink 61 being in contact with the bottom surface of the water tank 45. A fixing frame 62 is fixedly provided on the bottom surface of the inner wall of the water tank 45, and a rotating wheel 63 is rotatably provided on the fixing frame 62. Multiple sets of stirring blades 64 are arrayed on the outer surface of the rotating wheel 63. One of the water outlet pipes 59 has its output end located above one set of stirring blades 64 and maintaining a certain distance from it.

[0039] In practice, when the return water flows through the outlet pipe 59 into the water tank 45, the output end of one of the outlet pipes 59 is located above and at a certain distance from one of the agitators 64. The return water flows at a certain speed to impact the agitators 64, driving the rotor 63 to rotate around the fixed frame 62 fixed on the bottom surface of the inner wall of the water tank 45. The multiple sets of agitators 64 arranged in an array on the outer surface of the rotor 63 continuously agitate the water in the water tank 45, accelerating the evaporation and heat dissipation of the water surface. At the same time, a heat sink 61 is installed in the protective shell 60 fixed at the bottom of the water tank 45. The top surface of the heat sink 61 is in contact with the bottom surface of the water tank 45, transferring the heat of the water in the water tank 45 to the heat sink 61 and dissipating it into the outside air, further enhancing the cooling effect, so that the water temperature is reduced and recycled again, ensuring that the perforated plate 25 maintains the condensation temperature for a long time.

[0040] Working principle: When the distribution box is working, the fan 28 starts. Under the suction of the fan 28, the outside air enters through the air inlet pipe 21. First, it is coarsely filtered by the filter screen 22. After the airflow enters the groove 23 of the connecting shell 20, it passes through the perforated plate 25 in the four mounting slots 24 in sequence, and is then divided into left and right paths by the partition plate 46. Under the suction of the fan 28, air passes through each perforated plate 25 in sequence. At this time, circulating cooling water flows through the serpentine tube 50 on the back of the perforated plate 25 to keep the plate surface low. When the hot and humid air flows through the plate surface, the water vapor condenses into water droplets when it encounters the condensation. At the same time, the condensate forms a water film on the plate surface, adsorbing and capturing fine dust in the air. The condensate and dust-laden wastewater flow down along the surface of the perforated plate 25 and are discharged into the water tank 45 for temporary storage through the connecting groove 44 at the bottom of the mounting groove 24. The low-temperature clean air, after being dehumidified and dust-reduced by the perforated plate 25, enters the rear section of the groove 23 and is divided into two airflows by the partition plate 46. One airflow is discharged through the exhaust pipe 47 located on one side of the partition plate 46 as a low-temperature and low-humidity bypass airflow. The other airflow is retained in the groove 23 and heated by the hot water discharged into the water outlet pipe 29 by the serpentine pipe 50 to form a high-temperature and low-humidity dry airflow. Then it is discharged through the exhaust pipe 47 on the other side of the partition plate 46. The two airflows converge in the circular groove 59 and achieve temperature complementarity through mixing. The high temperature of the bypass cold air is neutralized by the hot air, and finally air with a temperature close to the ambient temperature and a reduced absolute moisture content is formed. This air is sent into the electrical distribution box body 10 by the fan 28, which simultaneously meets the requirements of anti-condensation and equipment heat dissipation. Excess gas in the box is discharged through the one-way valve of the exhaust port 11. To maintain the continuous dehumidification efficiency of the perforated plate 25, the motor 38 drives the cam 39 to rotate, which in turn pushes the U-shaped rod 35 to reciprocate through the extension rod 37. This causes the first and third perforated plates 25 connected to it to move laterally. At the same time, the U-shaped rod 35, through the cooperation of the connecting rod 34 and the slide rod 32, drives the second and fourth perforated plates 25 to move in the opposite direction. Combined with the collision between the first triangular block 42 at the bottom of the perforated plate 25 and the second triangular block 43 in the mounting groove 24, each perforated plate 25 generates high-frequency micro-vibration, which promptly shakes off dust and water droplets on the plate surface to prevent blockage. Wastewater falls into the water tank 45 through the connecting groove 44. During the cooling water circulation process, the water pump 58 pumps water from the water tank 45 through the output pipe 57 and the inlet pipe 56 into two U-shaped blocks 52 below the side wall of the fixed box 51. Each U-shaped block 52 is hollow and connected to two corresponding through slots 53 on the fixed box 51. The cooling water enters the input end of each serpentine tube 50 through the lower through slot 53, absorbs heat from the perforated plate 25 after flowing through the serpentine tube 50, and then enters the upper through slot 53 from the output end, flows into the upper U-shaped block 52, and is then output through two outlet pipes 59. The output ends of the two outlet pipes 59 extend into the water tank 45 through the groove 23, and the part of them in the groove 23 is continuous in an S-shape. The curved sections, all located on one side of the partition plate 46, are used to heat the airflow on that side. The returning water flow impacts the agitator 64 inside the water tank 45, driving the rotating wheel 63 to rotate around the fixed frame 62, agitating the water inside the water tank 45 to accelerate evaporation and heat dissipation. At the same time, the bottom surface of the water tank 45 is attached to the heat dissipation fins 61 installed inside the protective shell 60, further enhancing cooling, so that the water temperature is reduced and recycled again, ensuring that the perforated plate 25 maintains the condensation temperature for a long time. When the serpentine tube 50 moves with the perforated plate 25, the fixed plates 54 fixed at the water inlet and water outlet ends of the serpentine tube 50 slide in the corresponding sliding grooves 55 of the through groove 53, maintaining a stable and reliable connection and achieving dynamic sealing.
