Description

Technical Field

[0001] This invention relates to the field of high-voltage metering cabinet technology, and more specifically, to a floor-standing high-voltage metering cabinet. Background Technology

[0002] As a key facility in the power system used to connect the transmission network and the user end, the main function of the floor-mounted high-voltage metering cabinet is to accurately measure the amount of electricity consumed. The existing floor-mounted high-voltage metering cabinets are usually composed of a cabinet, a high-voltage transformer, metering instruments, secondary circuit protection devices, and a basic temperature and humidity management module. The cabinet usually adopts a metal enclosed structure to ensure the isolation of the internal electrical components from the outside world.

[0003] However, due to their floor-mounted installation, floor-mounted high-voltage metering cabinets are exposed to complex and variable outdoor or semi-outdoor environments for extended periods during actual operation. This is especially true in hot and humid southern regions, during the rainy season, or in coastal areas with salt spray, where a microenvironment of heat and humidity can easily form inside the cabinet. When the relative humidity is too high and temperature changes occur, condensation can occur on the surface of the insulation material inside the cabinet, significantly reducing the effective insulation performance of the creepage distance. This is particularly true in island or heavily salted areas, where salt spray particles enter the cabinet with the humid air and adhere to the insulation surface, absorbing moisture and forming a conductive film layer, which greatly reduces the surface resistivity of the insulation material.

[0004] To address this issue, existing technologies typically employ the installation of electric heaters or axial fans inside the cabinet to reduce relative humidity through heating or forced ventilation. However, while heating alone can raise the temperature and suppress condensation, it cannot remove the existing moisture inside the cabinet. Furthermore, ventilation and heat dissipation, when the external humidity is high, can actually draw humid air into the cabinet, creating a vicious cycle where the more ventilation is used, the more humid the environment becomes. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a floor-standing high-voltage metering cabinet, which aims to solve the above-mentioned technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A floor-standing high-voltage metering cabinet includes a floor-standing metering cabinet housing. A modular assembly inner frame is fixedly installed in the middle of the interior of the floor-standing metering cabinet housing to assemble a high-voltage transformer module, a metering instrument module, and a protection device module. A U-shaped cavity area with an opening facing away from the cabinet door is reserved at the outer edge of the modular assembly inner frame inside the floor-standing metering cabinet housing. A lead screw servo drive motor is fixedly installed at the bottom of the U-shaped cavity area. A U-shaped condensate mechanism is configured to be placed in the U-shaped cavity area through the lead screw servo drive motor. The U-shaped condensate mechanism is driven by the lead screw to move up and down along the U-shaped cavity area to act on different positions of the modular assembly inner frame. The U-shaped condensation mechanism includes a U-shaped frame, and two parallel liquid cooling pipes are arranged on the U-shaped frame near the cabinet door of the floor-standing metering cabinet. Each liquid cooling pipe is slidably equipped with a self-controlled liquid collection mechanism to absorb the condensed liquid and actively suppress condensation. Temporary storage boxes are fixedly installed on both parallel sides of the U-shaped frame. Each of the self-controlled liquid collection mechanisms is equipped with a corresponding transfer sleeve unit. The adsorbed condensate is transferred in real time through the transfer sleeve unit and introduced into the temporary storage boxes on both sides, serving as a heat dissipation medium to heat the interior of the floor-standing metering cabinet.

[0008] As a further aspect of the present invention: an extended top frame is fixedly installed on the top of the floor-standing metering cabinet housing, the interior of which is an additional cavity area to accommodate the top-mounted U-shaped condensate mechanism; cooling fans are fixedly installed at the bottom of the floor-standing metering cabinet housing and the top of the extended top frame to form a vertically flowing cooling duct; a first heat exchange fan is fixedly installed on the parallel sides of the U-shaped frame at the position on the side of the temporary storage box, and a heat dissipation fin is fixedly installed on the surface of each first heat exchange fan; a liquid cooling pump is fixedly installed on the side of the heat dissipation fin near the cabinet door, and an independent liquid cooling pipe is fixedly installed on the output end of each liquid cooling pump; the two liquid cooling pipes are arranged in parallel on the outside of the module assembly embedded frame near the cabinet door.

[0009] As a further aspect of the present invention: the U-shaped condensate mechanism further includes a first servo motor fixedly installed on the side of the liquid cooling pump. The surface of the first servo motor is configured with two independent output ends, and each output end is fixedly installed with a partitioned bidirectional threaded rod. The partitioned bidirectional threaded rod is located directly below the bottom of the liquid cooling pipe. The partitioned bidirectional threaded rod is a bidirectional threaded straight rod, and a partition protrusion is fixedly installed at the midpoint of the straight rod to divide the two sides into independent areas. The self-controlled liquid collection mechanism includes a fitting block engaged on each independent area. A collection box is fixedly installed on the surface of each fitting block.

[0010] As a further aspect of the present invention: the transfer sleeve unit includes hollow guide rods fixedly installed at the four corners of the top of the collection box, and a hollow annular cylinder is suspended at the top of the collection box through the four hollow guide rods. The interior of each hollow annular cylinder is fitted with a multi-purpose cotton tube unit. The multi-purpose cotton tube unit includes annular spacers fixedly installed at the outer edges of both ends of the hollow annular cylinder, and absorbent annular cotton blocks are fitted inside the hollow annular cylinder through the annular spacers at both ends. The absorbent annular cotton blocks are fitted onto the outer surface of the liquid cooling pipe directly opposite the top of the partition-type bidirectional threaded rod, and several limiting ropes for positioning the absorbent annular cotton blocks are equidistantly connected in a circular pattern on the annular spacers at both ends.

[0011] As a further aspect of the present invention: the multi-purpose cotton tube unit further includes an annular opening at the middle section of the adsorption annular cotton block, and an annular negative pressure airbag is installed in each annular opening. An annular spray hose is fixedly installed on each annular negative pressure airbag. The inner diameter of the annular spray hose is slightly larger than the inner diameter of the adsorption annular cotton block so as to be housed in the annular opening at the middle section. The spray nozzle of the annular spray hose faces the center of the adsorption annular cotton block. An annular airbag sleeve is fitted on the outer surface of the adsorption annular cotton block, and a first air supply hose for supplying air is connected to the side wall of the annular airbag sleeve.

[0012] As a further aspect of the present invention: the transfer sleeve unit further includes an adsorption coating fixedly installed at the top of the inner ring of the hollow annular cylinder. The bottom of the hollow annular cylinder is an open shape that is not closed, and a collection cover is fixedly installed on both sides of the open shape. The collection cover has an inward-facing structure that extends towards the top of the collection box. The hollow guide rod is embedded with an adsorption transfer rope, and the adsorption transfer rope passes through the inner cavity of the hollow annular cylinder and is connected to the four corners of the adsorption coating. A hollow drainage block for wrapping the adsorption transfer rope is fixedly installed at the junction of the hollow guide rod and the hollow annular cylinder.

[0013] As a further aspect of the present invention: the self-controlled liquid collection mechanism further includes a partition plate fixedly installed at the bottom of the collection tank. The partition plate divides the inside of the collection tank into an upper cavity for collecting liquid and a lower cavity for transferring liquid. A second servo motor is fixedly installed inside the lower cavity for transferring liquid. A drain pipe is fixedly installed on the top of the second servo motor. One end of the drain pipe is connected to the upper cavity for collecting liquid inside the collection tank, and the other end extends out of the collection tank and is connected to a second conveying hose. The second conveying hose is fixedly connected to a temporary storage box.

[0014] As a further aspect of the present invention: the self-controlled liquid collection mechanism further includes a gear sleeve fixedly installed at the output end of the second servo motor. The gear sleeve extends through the side wall of the collection box. Inside the collection box, irregularly shaped cavity blocks are fixedly installed through cavity drainage blocks on both sides. The irregularly shaped cavity blocks are racetrack-shaped cavities. A first sleeve is fixedly installed at the position between the two irregularly shaped cavity blocks. A second sleeve with the same center is fixedly installed inside the first sleeve. The adsorption transfer ropes all pass through the cavity drainage blocks into the interior of the irregularly shaped cavity blocks and through the irregularly shaped cavity blocks into the annular cavity between the first sleeve and the second sleeve.

[0015] As a further aspect of the present invention: a gear heat dissipation rotating rod is movably installed inside the second sleeve. The side end of the gear heat dissipation rotating rod is fixedly connected to a gear head identical to that of the gear sleeve head, and it is sealed through the side wall of the collection box and positioned directly above the gear sleeve head. A gear track that meshes with the gear sleeve head is installed on the outer surface of the second sleeve. A round opening is provided at the end of the second sleeve away from the gear track for the gear heat dissipation rotating rod to dissipate heat.

[0016] As a further aspect of the present invention: a surrounding sleeve is fixedly installed on one side of the collection cover extending into the top of the collection box, the surrounding sleeve being fitted onto the outer surface of the first sleeve, a number of heat-conducting metal sheets covering the outside of the drain pipe are fixedly installed on the top of the second servo motor, and a second heat exchange fan is fixedly installed on the side of the U-shaped frame near the cabinet door at the outer end of the liquid cooling pipe, and a humidity detection sensor is configured on the second heat exchange fan.

[0017] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: (1) By integrating active condensation and condensate transfer into a movable U-shaped condensate mechanism, active management of the humid and hot environment inside the cabinet is achieved. Compared with the existing technology that simply uses heating or ventilation, it actively promotes water vapor condensation by utilizing the low temperature of the liquid cooling pipe surface. The self-controlled liquid collection mechanism moves back and forth along the liquid cooling pipe to wipe away and absorb the condensed liquid water in real time, effectively avoiding the insulation risk caused by condensate dripping down the pipe wall onto electrical components. At the same time, the collected condensate is not directly discharged, but is transported to the temporary storage box as a heat dissipation medium and recycled back to the liquid cooling pipe by the liquid cooling pump. This solves the problem that traditional technology cannot remove existing moisture and that ventilation and heat dissipation easily introduce humid air in the external high humidity environment.

[0018] (2) The U-shaped condensation mechanism is driven to move up and down by the screw servo drive motor, so that the condensation treatment range can cover different height areas of the module assembly frame, adapt to the differences in humidity distribution in the cabinet, so that the adsorption ring cotton block is in close contact with the surface of the liquid cooling pipe to absorb liquid evenly, and then the condensation is periodically squeezed out by the ring airbag sleeve. With the combination of gravity dripping and capillary conduction dual transfer path, the condensation is efficiently collected into the collection box and transported to the temporary storage box through the drain pipe, ensuring that the adsorption material recovers its liquid absorption capacity after each squeeze and maintains a continuous condensation inhibition effect.

[0019] (3) By integrating condensation suppression with heat dissipation inside the cabinet, the cooling fans at the bottom and top form a vertically flowing heat dissipation channel, which does not interfere with the movement path of the U-shaped condensate mechanism, maintaining the overall heat dissipation capacity inside the cabinet. The cooling capacity carried by the condensate in the temporary storage box is transported towards the embedded frame of the module assembly, which helps to reduce the temperature inside the cabinet. The second servo motor drives the gear heat dissipation rod to rotate through the gear track, and works with the heat-conducting metal sheet to absorb the heat of the condensate in the drain pipe, further optimizing the cooling efficiency of the condensate, which helps to improve the operational reliability of the high-pressure metering cabinet in high temperature and high humidity or coastal salt spray environments.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0024] The following is a detailed description of a floor-standing high-voltage metering cabinet provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement them. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 9As shown, this embodiment of the invention provides a floor-standing high-voltage metering cabinet, including a floor-standing metering cabinet housing 1. A modular assembly inner frame 2 is fixedly installed in the middle of the interior of the floor-standing metering cabinet housing 1 to assemble a high-voltage transformer module, a metering instrument module, and a protection device module. A U-shaped cavity area with an opening facing away from the cabinet door is reserved at the outer edge of the modular assembly inner frame 2 inside the floor-standing metering cabinet housing 1. A lead screw servo drive motor 5 is fixedly installed at the bottom of the U-shaped cavity area. A U-shaped condensation mechanism 6, which is integrally placed in the U-shaped cavity area, is engaged by the lead screw servo drive motor 5. The U-shaped condensation mechanism 6 is driven by the lead screw to move up and down along the U-shaped cavity area to act on different positions of the modular assembly inner frame 2. The U-shaped condensation mechanism 6 includes a U-shaped frame 61, and two parallel liquid cooling pipes 65 are arranged on the side of the U-shaped frame 61 near the door of the floor-standing metering cabinet 1. Each liquid cooling pipe 65 is slidably equipped with a self-controlled liquid collection mechanism 7 to absorb the condensed liquid and actively suppress condensation. Temporary storage boxes 9 are fixedly installed on both parallel sides of the U-shaped frame 61. Each of the self-controlled liquid collection mechanisms 7 is equipped with a corresponding transfer sleeve unit 79. The adsorbed condensate is transferred in real time through the transfer sleeve unit 79 and introduced into the temporary storage boxes 9 on both sides, serving as a heat dissipation medium to heat the interior of the floor-standing metering cabinet 1.

[0026] To address the problem that existing floor-standing high-pressure metering cabinets frequently experience condensation due to heat and moisture accumulation in high-temperature and high-humidity environments, and that heating or ventilation alone cannot effectively remove existing moisture, the above-mentioned technical solution is adopted. This solution mainly consists of a floor-standing metering cabinet housing 1, a modular assembly embedded frame 2, a lead screw servo drive motor 5, a U-shaped condensation mechanism 6, a self-controlled liquid collection mechanism 7, a temporary storage box 9, and a transfer sleeve unit 79.

[0027] Specifically, the floor-standing metering cabinet housing 1 serves as the overall load-bearing structure, adopting a metal enclosed cabinet structure. A modular assembly embedded frame 2 is fixedly installed in the middle of its interior. This modular assembly embedded frame 2 is used to centrally assemble core electrical units such as high-voltage transformer modules, metering instrument modules, and protection device modules, forming a relatively concentrated working area. Inside the floor-standing metering cabinet housing 1, at the outer edge of the modular assembly embedded frame 2, a U-shaped cavity area with an opening facing away from the cabinet door is reserved. This U-shaped cavity area spatially surrounds the front and sides of the modular assembly embedded frame 2, forming an independent channel area to accommodate the U-shaped condensate mechanism 6 and provide its reciprocating movement path.

[0028] A lead screw servo drive motor 5 is fixedly installed at the bottom of the U-shaped cavity area. Its output end is engaged with a U-shaped condensation mechanism 6, which is placed inside the U-shaped cavity area, through a lead screw transmission mechanism. Driven by the lead screw servo drive motor 5, the U-shaped condensation mechanism 6 moves up and down reciprocally along the extension direction of the U-shaped cavity area, thereby enabling it to act on different height positions of the module assembly embedded frame 2. This allows the condensation treatment to actively cover the entire module assembly area according to the humidity distribution inside the cabinet, achieving active intervention on condensation at multiple points and in multiple areas. The U-shaped condensation mechanism 6 has a U-shaped configuration, including a U-shaped frame 61 as a supporting skeleton. On the U-shaped frame 61, near the cabinet door of the floor-standing metering cabinet 1, two parallel liquid cooling pipes 65 are arranged. As a cooling element, when the surface temperature of the liquid cooling pipes 65 is lower than the dew point of the air inside the cabinet, it can cause the moisture in the air to condense into liquid water on its surface, thereby actively reducing the humidity of the air inside the cabinet. Each liquid cooling pipe 65 is equipped with a self-controlled liquid collection mechanism 7. The self-controlled liquid collection mechanism 7 can move along the surface of the liquid cooling pipe 65 and absorb the liquid condensed on the surface of the liquid cooling pipe 65 during the movement. Compared with the passive waiting for the droplets to fall naturally, it can remove the condensate in time and prevent the condensate from flowing along the pipe wall or dripping onto the electrical components below, thereby actively suppressing condensation and avoiding secondary pollution and insulation risks. Temporary storage boxes 9 are fixedly installed on both parallel sides of the U-shaped frame 61 for temporarily storing condensate collected and transferred from the self-controlled liquid collection mechanism 7. Each self-controlled liquid collection mechanism 7 is equipped with a corresponding transfer sleeve unit 79. The transfer sleeve unit 79 serves as a liquid conduction channel, enabling the real-time transfer of the condensate adsorbed by the self-controlled liquid collection mechanism 7 into the temporary storage boxes 9 on both sides. The condensate collected and temporarily stored in the temporary storage box 9 is not simply discharged as waste liquid, but is used as a heat dissipation medium in the reverse heat dissipation process inside the floor-standing metering cabinet shell 1, realizing the active management and resource utilization of the humid and hot environment inside the cabinet, and improving the operational reliability of the metering cabinet in complex environments.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, an extended top frame 3 is fixedly installed on the top of the floor-standing metering cabinet housing 1. The interior of the extended top frame 3 is an additional cavity area to accommodate the top-mounted U-shaped condensate mechanism 6. Cooling fans 4 are fixedly installed at the bottom of the floor-standing metering cabinet housing 1 and the top of the extended top frame 3 to form a vertically flowing cooling duct. First heat exchange fans 62 are fixedly installed on the parallel sides of the U-shaped frame 61 at the positions on the sides of the temporary storage box 9. Each side of the first heat exchange fan 62 has a heat dissipation fin 63 fixedly installed on its surface. A liquid cooling pump 64 is fixedly installed on the side of the heat dissipation fin 63 near the cabinet door. An independent liquid cooling pipe 65 is fixedly installed on the output end of each side of the liquid cooling pump 64. The two liquid cooling pipes 65 are arranged in parallel on the outside of the module assembly embedded frame 2 near the cabinet door.

[0030] The extended top frame 3 is fixedly installed on the top of the floor-standing metering cabinet housing 1. The interior of the extended top frame 3 forms an additional cavity area. This cavity area is located above the top of the floor-standing metering cabinet housing 1. Its size matches the U-shaped configuration of the U-shaped condensate mechanism 6. It is used to store the U-shaped condensate mechanism 6 when it moves to the top limit position. This allows the U-shaped condensate mechanism 6 to be completely housed inside the extended top frame 3 during non-working periods or maintenance, avoiding long-term occupation of the effective space inside the cabinet. It also reduces obstruction of the module assembly embedded frame 2, facilitating daily inspection and maintenance.

[0031] Cooling fans 4 are fixedly installed at the bottom of the floor-standing metering cabinet housing 1 and the top of the extended top frame 3. The two cooling fans 4 are arranged opposite each other in the vertical direction. The cooling fan 4 at the bottom introduces cooler air from outside into the cabinet, while the cooling fan 4 at the top draws out the hot air accumulated inside the cabinet. This forms a cooling air duct that flows from bottom to top inside the floor-standing metering cabinet housing 1. The vertically connected forced convection air duct works in conjunction with the U-shaped condensation mechanism 6. When the U-shaped condensation mechanism 6 moves up and down in the U-shaped cavity area, its own structure does not block the continuity of the cooling air duct. Thus, while actively suppressing condensation, the overall heat dissipation capacity inside the cabinet remains stable.

[0032] The U-shaped frame 61 serves as the supporting skeleton for the U-shaped condensation mechanism 6. A first heat exchange fan 62 is fixedly installed on each of its parallel sides at a position on the side of the temporary storage box 9. Each first heat exchange fan 62 is arranged adjacent to the temporary storage box 9 on the same side. The air outlet direction of the first heat exchange fan 62 is directed towards the inner frame 2 of the module assembly, used to transport low-temperature air from the temporary storage box 9 and its surrounding area towards the inner frame 2 of the module assembly. Furthermore, each surface of the first heat exchange fan 62 is fixedly equipped with heat dissipation fins 63. The heat dissipation fins 63 adopt a dense fin structure, with their fin extension direction consistent with the air outlet direction of the first heat exchange fan 62, used to increase the contact area with the air. When the first heat exchange fan 62 is working, the airflow passes over the surface of the heat dissipation fins 63, enhancing local heat dissipation efficiency through heat exchange, while simultaneously reducing the temporary storage temperature of the temporary storage box 9. The liquid cooling pump 64 serves as the power source for coolant circulation. Its input end is connected to the temporary storage box 9 via a pipeline. It is used to extract and pressurize the condensate collected in the temporary storage box 9 for output. Each side of the liquid cooling pump 64 has an independent liquid cooling pipe 65 fixedly installed at its output end. That is, the left liquid cooling pump 64 is connected to the left liquid cooling pipe 65, and the right liquid cooling pump 64 is connected to the right liquid cooling pipe 65. The two liquid cooling pipes 65 are independent of each other and are not connected. During operation, one is the main pipe and the other is the auxiliary pipe. The main pipe is responsible for cooling and condensation, while the auxiliary pipe is responsible for temperature compensation to prevent the main pipe from freezing or the temperature inside the cabinet from being too low and affecting the operation of the equipment. The surface of the pipe body serves as a cooling interface. The liquid cooling pump 64 drives the condensate in the temporary storage box 9 to circulate inside the liquid cooling pipe 65, so that the surface of the liquid cooling pipe 65 is maintained at a temperature lower than the dew point of the air inside the cabinet, which promotes the active condensation of water vapor in the air on the surface of the liquid cooling pipe 65.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the U-shaped condensate mechanism 6 also includes a first servo motor 66 fixedly installed on the side of the liquid cooling pump 64. The surface of the first servo motor 66 is configured with two independent output ends, and each output end is fixedly installed with a partitioned bidirectional threaded rod 67. The partitioned bidirectional threaded rod 67 is located directly below the bottom of the liquid cooling pipe 65. The partitioned bidirectional threaded rod 67 is a bidirectional threaded straight rod, and a partition protrusion is fixedly installed at the midpoint of the straight rod to divide the two sides into independent areas. The self-controlled liquid collection mechanism 7 includes a fitting block 71 engaged with each independent area on both sides. A collection box 72 is fixedly installed on the surface of the fitting block 71.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the transfer sleeve unit 79 includes hollow guide rods 791 fixedly installed at the four corners of the top of the collection box 72, and hollow annular cylinders 792 are suspended at the top of the collection box 72 through the four hollow guide rods 791. Each hollow annular cylinder 792 is fitted with a multi-purpose cotton tube unit 710. The multi-purpose cotton tube unit 710 includes annular spacers 7101 fixedly installed at the outer edges of both ends of the hollow annular cylinder 792, and absorbent annular cotton blocks 7102 are fitted inside the hollow annular cylinder 792 through the annular spacers 7101 at both ends. The absorbent annular cotton blocks 7102 are fitted onto the outer surface of the liquid cooling pipe 65 directly opposite the top of the partition-type bidirectional threaded rod 67, and several limiting ropes 7103 for positioning the absorbent annular cotton blocks 7102 are equidistantly connected in a circular pattern on the annular spacers 7101 at both ends.

[0035] The first servo motor 66 is fixedly installed on the side of the liquid cooling pump 64, serving as the power source for driving the reciprocating movement of the self-controlled liquid collection mechanism 7. The first servo motor 66 is a drive motor with two independent output ends, capable of independent servo control, as is common in the prior art. The two output ends are parallel to each other in space and extend towards the liquid cooling pipes 65 on both sides. Each output end is fixedly equipped with a partitioned bidirectional threaded rod 67, forming a one-to-one corresponding driving relationship. The partitioned bidirectional threaded rod 67 is a bidirectional threaded straight rod with two sections of threads in a helical direction machined on its surface. A fitting block 71 engages with the threads in each independent section. The fitting block 71 has an internal thread that matches the thread. When the partitioned bidirectional threaded rod 67 rotates, the fitting block 71 reciprocates along the axial direction of the rod. A collection box 72 is fixedly installed on the surface of the sleeve block 71. The collection box 72 moves synchronously with the sleeve block 71, thereby realizing the bidirectional sliding of the self-controlled liquid collection mechanism 7 on the liquid cooling pipe 65, so as to actively adsorb condensate in different sections of the liquid cooling pipe 65. The configured transfer sleeve unit 79 is used to transfer the condensate absorbed by the adsorption ring cotton block 7102 to the collection box 72 in real time. There are four hollow guide rods 791, which are fixedly installed at the four corners of the top of the collection box 72. All four hollow guide rods 791 extend vertically upward, and their tops jointly support and suspend a hollow ring cylinder 792. The hollow ring cylinder 792 has a cylindrical structure, and its inner wall has a hollow cavity for containing and conducting liquid. The hollow annular cylinder 792 is coaxially fitted with a multi-purpose cotton tube unit 710. The multi-purpose cotton tube unit 710 includes annular spacers 7101 and adsorption annular cotton blocks 7102. There are two annular spacers 7101, which are fixedly installed at the outer edges of both ends of the hollow annular cylinder 792. They are used to limit and fix the adsorption annular cotton blocks 7102 at both ends in the axial direction. The adsorption annular cotton blocks 7102 are generally annular, and their inner diameter matches the outer diameter of the liquid cooling pipe 65. The adsorption annular cotton blocks 7102 are held inside the hollow annular cylinder 792 by the annular spacers 7101 at both ends, and are fitted as a whole on the outer pipe surface of the liquid cooling pipe 65, which is located opposite the top of the partitioned bidirectional threaded rod 67.

[0036] The absorbent ring cotton block 7102 is made of highly absorbent hydrophilic fiber material, including but not limited to moisture-absorbing cotton felt made of sodium polyacrylate highly absorbent resin fiber and hydrophilic polyester fiber. It has excellent moisture absorption and water retention properties during operation and can quickly absorb condensed water droplets when in contact with the surface of the liquid cooling pipe 65. It also has good heat resistance and aging resistance, and is suitable for long-term operation environment inside the high-pressure metering cabinet. At both ends of the adsorption ring cotton block 7102, several limiting ropes 7103 are circumferentially and equidistantly connected on the ring spacer 7101 at each end. The limiting ropes 7103 extend axially and are tightly attached to the outer surface of the adsorption ring cotton block 7102, firmly binding the adsorption ring cotton block 7102 to the outer surface of the liquid cooling pipe 65. This prevents the adsorption ring cotton block 7102 from axially shifting or radially loosening during the movement of the collection box 72, ensuring that the adsorption ring cotton block 7102 is always in close contact with the surface of the liquid cooling pipe 65. This maintains a stable liquid absorption efficiency and also avoids scratching the outer surface of the liquid cooling pipe 65 at the limiting end. When the self-controlled liquid collection mechanism 7 moves along the liquid cooling pipe 65, the adsorption ring cotton block 7102 wipes away and absorbs the liquid condensed on the surface of the liquid cooling pipe 65 in real time. The absorbed liquid is guided to the collection box 72 through the internal channel of the subsequent transfer sleeve unit 79, realizing the active collection and transfer of condensate.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the multi-purpose cotton tube unit 710 also includes an annular opening at the middle section of the adsorption annular cotton block 7102, and an annular negative pressure airbag 7105 is installed in each annular opening. An annular spray hose 7106 is fixedly installed on each annular negative pressure airbag 7105. The inner diameter of the annular spray hose 7106 is slightly larger than the inner diameter of the adsorption annular cotton block 7102 so that it can be stored in the annular opening at the middle section. The spray nozzle of the annular spray hose 7106 faces the center of the adsorption annular cotton block 7102. An annular airbag sleeve 7104 is fitted on the outer surface of the adsorption annular cotton block 7102, and a first air supply hose 7107 is connected to the side wall of the annular airbag sleeve 7104.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the transfer sleeve unit 79 also includes an adsorption coating 793 fixedly installed at the top of the inner ring of the hollow annular cylinder 792. The bottom of the hollow annular cylinder 792 is an open shape that is not closed, and a collection cover 796 is fixedly installed on both sides of the open shape. The collection cover 796 has an inward-facing structure that extends towards the top of the collection box 72. The hollow guide rod 791 is embedded with an adsorption transfer rope 794, and the adsorption transfer rope 794 passes through the inner cavity of the hollow annular cylinder 792 and is connected to the four corners of the adsorption coating 793. A hollow guide block 795 for wrapping the adsorption transfer rope 794 is fixedly installed at the junction of the hollow guide rod 791 and the hollow annular cylinder 792.

[0039] The configured absorbent ring cotton block 7102 has a ring opening at the middle section. The ring opening surrounds the entire circumference of the absorbent ring cotton block 7102 and is used to accommodate and install the ring-shaped negative pressure airbag 7105 and the ring-shaped spray hose 7106. The ring-shaped negative pressure airbag 7105 is installed in the ring opening. The ring-shaped negative pressure airbag 7105 is pre-stored with a hydrophilic modification reagent. The hydrophilic modification reagent is a hydrophilic water solution containing surfactants, which is used to form a hydrophilic film layer on the surface of the liquid cooling pipe 65, reduce the water contact angle, and promote the uniform condensation of water vapor on the surface of the liquid cooling pipe 65. A circular spray hose 7106 is fixedly installed on the circular negative pressure airbag 7105. The circular spray hose 7106 has an overall ring structure, and its inner diameter is slightly larger than that of the absorbent circular cotton block 7102. This allows the circular spray hose 7106 to be housed in the circular opening at the middle section of the absorbent circular cotton block 7102 and to be coaxially arranged with the absorbent circular cotton block 7102. Multiple spray nozzles are provided on the wall of the circular spray hose 7106. These nozzles are all oriented towards the center of the absorbent circular cotton block 7102, i.e., towards the outer surface of the liquid cooling pipe 65, and are used to spray the hydrophilic modification reagent stored in the circular negative pressure airbag 7105 onto the surface of the liquid cooling pipe 65. The annular negative pressure airbag 7105 is equipped with a one-way valve at its air inlet. The external air supply line is connected to the annular negative pressure airbag 7105 through this one-way valve. Only when it is necessary to release the reagent, the external air source applies air pressure to the annular negative pressure airbag 7105, forcing the internal reagent to be discharged through the spray port of the annular spray hose 7106. In the non-working state, the one-way valve remains closed to prevent reagent leakage or evaporation.

[0040] A circular airbag sleeve 7104 is fitted on the outer surface of the adsorption circular cotton block 7102. The circular airbag sleeve 7104 is made of elastic airtight material, and its inner wall is tightly attached to the outer surface of the adsorption circular cotton block 7102. A first delivery hose 7107 for supplying air is connected to the side wall of the circular airbag sleeve 7104. The other end of the first delivery hose 7107 is connected to an external servo air supply module. When the self-controlled liquid collection mechanism 7 moves to the designated section of the liquid cooling pipe 65 and needs to discharge the condensate absorbed in the adsorption circular cotton block 7102, the external servo air supply module fills the circular airbag sleeve 7104 with compressed gas through the first delivery hose 7107, causing the circular airbag sleeve 7104 to expand. After the annular airbag sleeve 7104 expands, it radially compresses and adsorbs the annular cotton block 7102. Because the adsorbent annular cotton block 7102 is limited in both the axial and radial directions by the annular spacers 7101 at both ends and the limiting ropes 7103, it cannot move axially under radial pressure and can only be compressed in the radial direction. This creates an effect similar to squeezing a sponge, squeezing the condensate absorbed inside the adsorbent annular cotton block 7102 from its inner wall. The squeezed-out condensate drips downwards along the surface of the liquid cooling pipe 65 or flows along the pipe wall, entering the collection structure below.

[0041] During non-squeezing drainage cycles, when pretreatment of the liquid cooling tube 65 surface is required to enhance condensation, an external air source applies air pressure to the annular negative pressure airbag 7105 through a one-way valve. This deforms the annular negative pressure airbag 7105, squeezing the hydrophilic modification reagent stored inside into the annular spray hose 7106. The reagent is then sprayed out through the spray nozzle of the annular spray hose 7106, uniformly coating the outer surface of the liquid cooling tube 65. This hydrophilic modification reagent forms a hydrophilic film on the surface of the liquid cooling tube 65, reducing the nucleation barrier when water vapor condenses on the surface of the liquid cooling tube 65. This makes it easier for water vapor to form a uniform thin layer of condensation on the surface of the liquid cooling tube 65, rather than dispersed bead-like condensation, thereby improving condensation efficiency. This allows the liquid cooling tube 65 to more efficiently capture and remove moisture from the air inside the cabinet, providing a more stable liquid source for subsequent condensation suppression and heat dissipation cycles.

[0042] The adsorption coating 793 is fixedly installed at the top of the inner ring of the hollow annular cylinder 792. The adsorption coating 793 is made of a highly absorbent porous material with a capillary structure on its surface, which can adsorb the condensate squeezed out from the adsorption annular cotton block 7102, and facilitate better transfer of the liquid at the top of the adsorption annular cotton block 7102. The bottom of the hollow annular cylinder 792 is designed to be an open shape, allowing the condensate squeezed out from the absorbent annular cotton block 7102 to drip downwards through the opening. Collection covers 796 are fixedly installed on both sides of the bottom opening of the hollow annular cylinder 792. The collection covers 796 have an inward-facing structure that extends towards the top of the collection box 72. That is, the open end of the collection cover 796 faces the inside of the hollow annular cylinder 792, while its narrow end extends towards the top of the collection box 72. This is used to collect and guide the condensate dripping from the bottom of the hollow annular cylinder 792 into the upper cavity of the collection box 72.

[0043] The hollow guide rod 791 is internally embedded with adsorption transfer ropes 794. The adsorption transfer ropes 794 are fiber bundles with capillary conduction properties in the prior art, including capillary ropes woven from polypropylene fibers in the prior art, which can realize spontaneous liquid transport by utilizing capillary effect. One end of the adsorption transfer rope 794 is inserted into the inner cavity of the hollow annular cylinder 792 and fixedly connected to the four side corners of the adsorption coating 793, so that the condensate adsorbed by the adsorption coating 793 can be discharged outward along the adsorption transfer rope 794 through capillary action. The other end of the adsorption transfer rope 794 extends downward along the inside of the hollow guide rod 791 and finally connects to the liquid collection structure inside the collection box 72. Hollow guide blocks 795 are fixedly installed at the junction of the hollow guide rod 791 and the hollow annular cylinder 792. The hollow guide blocks 795 are wrapped around the outside of the adsorption transfer rope 794 to position and seal the adsorption transfer rope 794, prevent liquid from overflowing at the junction, and ensure the continuity of the capillary conduction path.

[0044] When the annular airbag sleeve 7104 expands and squeezes the adsorbent annular cotton block 7102, part of the squeezed-out condensate drips down along the surface of the liquid cooling pipe 65, enters the collection hood 796 through the bottom opening of the hollow annular cylinder 792, and finally flows into the upper cavity of the collection box 72. The other part of the condensate is absorbed by the adsorption coating 793 and is conducted downward along the adsorption transfer rope 794 through capillary action. Through the internal channels of the hollow guide block 795 and the hollow guide rod 791, it also flows into the annular cavity between the first sleeve 712 and the second sleeve 713 on the upper side of the collection box 72, ensuring that one end of the adsorbent annular cotton block 7102 can dissipate heat better and maintain the condensation effect better. Through the dual transfer path combining gravity dripping and capillary conduction, the condensate absorbed by the adsorbent ring cotton block 7102 is transferred to the collection box 72 in real time, ensuring that the adsorbent ring cotton block 7102 can restore its liquid absorption capacity after each squeeze, and maintaining a continuous cycle of condensation adsorption and transfer.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the self-controlled liquid collection mechanism 7 also includes a partition plate 73 fixedly installed at the bottom of the collection tank 72. The partition plate 73 divides the inside of the collection tank 72 into an upper cavity for collecting liquid and a lower cavity for transferring liquid. A second servo motor 76 is fixedly installed inside the lower cavity for transferring liquid. A drain pipe 74 is fixedly installed on the top of the second servo motor 76. One end of the drain pipe 74 is connected to the upper cavity for collecting liquid inside the collection tank 72, and the other end extends out of the collection tank 72 and is connected to a second delivery hose 10. The second delivery hose 10 is fixedly connected to the temporary storage box 9.

[0046] The second delivery hose 10 is configured to stably transfer the actively precipitated condensate inside the cabinet to the temporary storage box 9.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the self-controlled liquid collection mechanism 7 also includes a gear sleeve 77 fixedly installed at the output end of the second servo motor 76. The gear sleeve 77 extends through the side wall of the collection box 72. Inside the collection box 72, an irregularly shaped cavity block 711 is fixedly installed through cavity drainage blocks 795 on both sides. The irregularly shaped cavity block 711 is a racetrack-shaped cavity, and a first sleeve 712 is fixedly installed at the position between the two irregularly shaped cavity blocks 711. Inside the first sleeve 712, a second sleeve 713 with the same center is fixedly installed. The adsorption transfer rope 794 passes through the cavity drainage block 795 into the interior of the irregularly shaped cavity block 711, and passes through the irregularly shaped cavity block 711 into the annular cavity between the first sleeve 712 and the second sleeve 713.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a gear cooling rod 714 is movably installed inside the second sleeve 713. The side end of the gear cooling rod 714 is fixedly connected to a gear head identical to that of the gear sleeve 77, and it passes through the side wall of the collection box 72 and is positioned directly above the gear sleeve 77. A gear track 78 that meshes with the gear sleeve 77 is installed on the outer surface. The end of the second sleeve 713 away from the gear track 78 has a round opening for the gear cooling rod 714 to dissipate heat.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a surrounding sleeve 797 is fixedly installed on one side of the collection cover 796 extending into the top of the collection box 72. The surrounding sleeve 797 is fitted onto the outer surface of the first sleeve 712. Several heat-conducting metal sheets 75 covering the outside of the drain pipe 74 are fixedly installed on the top of the second servo motor 76. A second heat exchange fan 8 is fixedly installed on the side of the U-shaped frame 61 near the cabinet door at the outer end of the liquid cooling pipe 65. A humidity detection sensor is configured on the second heat exchange fan 8.

[0050] The partition plate 73 is fixedly installed at the bottom of the collection box 72, dividing the internal space of the collection box 72 into two independent areas: an upper cavity and a lower cavity. The upper cavity is used to collect the condensate flowing in from the collection cover 796, forming a liquid storage area. The lower cavity is used to accommodate the second servo motor 76 and related liquid transfer components, forming a drive and transfer area. The second servo motor 76 is fixedly installed inside the lower cavity used for liquid transfer. One end of the drain pipe 74 is connected to the upper cavity inside the collection box 72 for collecting liquid, and is used to absorb the condensate accumulated in the upper cavity. The other end of the drain pipe 74 extends out of the side wall of the collection box 72 and is connected to a second delivery hose 10. The end of the second delivery hose 10 is fixedly connected to the temporary storage box 9. When there is condensate in the upper cavity, it can be transported to the temporary storage box 9 through the second delivery hose 10. The configured gear sleeve 77 is fixedly installed at the output end of the second servo motor 76. The gear sleeve 77 protrudes through the side wall of the collection box 72 and is used to transmit the rotational power of the second servo motor 76 outward. Inside the collection box 72, an irregular cavity block 711 is fixedly installed through the cavity guide blocks 795 on both sides. The irregular cavity block 711 has a racetrack-shaped cavity structure, that is, a hollow cavity that extends along the length direction and has semi-circular ends. This cavity is located in the middle of the internal space of the collection box 72. A first sleeve 712 is fixedly installed between the two irregularly shaped cavity blocks 711. The first sleeve 712 is a cylindrical structure with its axis extending horizontally. A second sleeve 713 with the same center is fixedly installed inside the first sleeve 712. The outer diameter of the second sleeve 713 is smaller than the inner diameter of the first sleeve 712, so that an annular cavity channel is formed between the first sleeve 712 and the second sleeve 713. The adsorption transfer rope 794 passes through the cavity guide block 795 into the interior of the irregularly shaped cavity block 711 and extends along the internal cavity of the irregularly shaped cavity block 711. Finally, it passes into the annular cavity between the first sleeve 712 and the second sleeve 713, so that the end of the adsorption transfer rope 794 is exposed in the annular cavity, which facilitates the collection of the condensate in the annular cavity. The collected liquid is used as a medium to further stabilize the temperature of the adsorption ring cotton block 7102, so as to more stably complete the work of actively condensing the liquid in the cabinet at low temperature.

[0051] The configured gear cooling rotating rod 714 is movably installed inside the second sleeve 713. A gear head is fixedly connected to the side end of the gear cooling rotating rod 714. The gear head has the same gear structure as the gear sleeve 77. The gear head is sealed and protrudes through the side wall of the collection box 72 and is positioned directly above the gear sleeve 77. A gear track 78 is meshed on the outer surfaces of the gear head and the gear sleeve 77. The gear track 78 is an annular toothed transmission belt that transmits the rotational power from the output end of the second servo motor 76 from the gear sleeve 77 to the gear cooling rotating rod. The gear head of 714 drives the gear heat dissipation rod 714 to rotate inside the second sleeve 713. The end of the second sleeve 713 away from the gear track 78 has a round opening that passes through the end of the second sleeve 713. When the gear heat dissipation rod 714 rotates, the heat generated by the friction between the gear heat dissipation rod 714 and the second sleeve 713, as well as the heat of the surrounding air, is dissipated outward through the round opening. At the same time, the round opening also provides an evaporation channel for the condensate conducted by the adsorption transfer rope 794 to the annular cavity, thus helping to improve the heat dissipation efficiency. A surrounding sleeve 797 is fixedly installed on one side of the collection cover 796 extending into the top of the collection tank 72. The surrounding sleeve 797 is entirely fitted onto the outer surface of the first sleeve 712, used to further guide the condensate introduced from the collection cover 796 to the outer surface area of ​​the first sleeve 712, enhancing the contact heat exchange effect between the liquid and the first sleeve 712. Simultaneously, to ensure that the liquid guided to the outer surface area of ​​the first sleeve 712 can fall better into the collection tank 72, the surrounding sleeve 797 is made of a thermally conductive and water-permeable material. Several thermally conductive metal sheets 75 are fixedly installed on the top of the second servo motor 76. The thermally conductive metal sheets 75 are thin sheets covering the outside of the drain conduit 74. The thermally conductive metal sheets 75 are made of a high thermal conductivity metal material in the prior art, used to absorb the heat carried by the condensate flowing inside the drain conduit 74 and the heat generated by the second servo motor 76 during operation, and conduct the heat to the surrounding air, helping to lower the temperature of the condensate.

[0052] A second heat exchange fan 8 is fixedly installed on the side of the U-shaped frame 61 near the cabinet door, at the outer end of the liquid cooling pipe 65. The air outlet direction of the second heat exchange fan 8 is set towards the inner frame 2 of the module assembly. It is used to deliver cold energy towards the inner frame 2 of the module assembly while condensation treatment is performed on the surface of the liquid cooling pipe 65, thus assisting in heat dissipation inside the cabinet. The second heat exchange fan 8 is equipped with a humidity detection sensor, which is electrically connected to the control system inside the cabinet. It is used to detect the relative humidity of the air inside the cabinet in real time and feed the humidity signal back to the control system. Based on the feedback signal from the humidity detection sensor, the control system adjusts the lead screw servo drive motor 5 to move the entire U-shaped condensation mechanism 6 to the most humid height position inside, realizing the coordinated control of condensation suppression and heat dissipation functions.

[0053] The usage method provided by this invention is as follows: In use, the present invention firstly uses a humidity sensor mounted on the second heat exchange fan 8 to monitor the relative humidity inside the floor-standing metering cabinet housing 1 in real time. When the detected humidity value exceeds a preset threshold, the control system initiates a condensation suppression process. The lead screw servo drive motor 5 starts, driving the U-shaped condensation mechanism 6, which is placed within the U-shaped cavity, to move up and down along the U-shaped cavity, moving it to the higher humidity area corresponding to the embedded frame 2 of the module assembly. Simultaneously, the liquid cooling pump 64 starts, extracting and pressurizing the condensate stored in the temporary storage box 9 and delivering it to the inside of the liquid cooling pipe 65. This lowers the surface temperature of the liquid cooling pipe 65 to below the dew point temperature of the air inside the cabinet, causing water vapor in the air to condense into liquid water on the surface of the liquid cooling pipe 65. The first servo motor 66 drives the partitioned bidirectional threaded rod 67 to rotate. The partitioned bidirectional threaded rod 67 drives the sleeve block 71 to reciprocate along the rod axis. The sleeve block 71 drives the collection box 72 and the cavity guide rod 791, the cavity annular cylinder 792 and the adsorption annular cotton block 7102 fixed on the top of the collection box 72 to slide synchronously along the surface of the liquid cooling pipe 65. During the sliding process, the adsorption annular cotton block 7102 adheres closely to the outer surface of the liquid cooling pipe 65, wiping away and absorbing the liquid condensed on the surface of the liquid cooling pipe 65 in real time.

[0054] Then, when the self-controlled liquid collection mechanism 7 moves along the liquid cooling pipe 65 to the designated section, the external servo gas supply module fills the annular airbag sleeve 7104 with compressed gas through the first delivery hose 7107. After the annular airbag sleeve 7104 expands, it radially squeezes and adsorbs the annular cotton block 7102. The adsorbed annular cotton block 7102 is limited by the annular spacers 7101 at both ends and the limiting rope 7103. Under radial compression, the condensate absorbed inside it is squeezed out from the inner wall surface. Part of the squeezed condensate drips down the surface of the liquid cooling pipe 65 and enters the collection hood 796 through the unsealed opening at the bottom of the hollow annular cylinder 792. The collection hood 796 concentrates and guides the dripping condensate into the upper cavity of the collection box 72. The other part of the condensate is absorbed by the adsorption coating 793 on the top of the inner ring of the hollow annular cylinder 792. The condensate adsorbed by the adsorption coating 793 is conducted downward along the adsorption transfer rope 794 through capillary action and flows into the annular cavity between the first sleeve 712 and the second sleeve 713 through the internal channels of the hollow guide block 795 and the hollow guide rod 791 for heat dissipation to better maintain the temperature of the adsorption annular cotton block 7102.

[0055] Then, during the condensation suppression process, the first heat exchange fan 62 starts, with its air outlet direction facing the inner frame 2 of the module assembly. This transports the low-temperature air from the temporary storage box 9 and surrounding area towards the inner frame 2. Simultaneously, the heat dissipation fins 63 increase their contact area with the air, enhancing local heat dissipation efficiency. The second servo motor 76 drives the gear cooling rod 714 to rotate inside the second sleeve 713 via the gear sleeve 77 and gear track 78. As the gear cooling rod 714 rotates, the heat generated by friction between it and the second sleeve 713, as well as the heat from the surrounding air, is dissipated outwards through the round opening at the end of the second sleeve 713. The heat-conducting metal sheet 75 absorbs the heat carried by the condensate flowing inside the drain pipe 74 and the heat generated by the second servo motor 76 during operation, and conducts this heat to the surrounding air, assisting in lowering the temperature of the condensate. The second heat exchange fan 8 starts, transporting the cold energy generated on the surface of the liquid cooling pipe 65 towards the inner frame 2 of the module assembly, assisting in heat dissipation within the cabinet.

[0056] Finally, when the humidity sensor detects that the humidity inside the cabinet has dropped below the preset threshold, the control system stops the operation of the lead screw servo drive motor 5, the first servo motor 66, the liquid cooling pump 64, the first heat exchange fan 62, the second servo motor 76, and the second heat exchange fan 8. The lead screw servo drive motor 5 drives the U-shaped condensation mechanism 6 to move into the cavity area inside the extended top frame 3 for storage, so that the U-shaped condensation mechanism 6 is completely housed inside the extended top frame 3, completing the condensation suppression and heat dissipation coordinated control process.

[0057] During long-term operation, when it is necessary to pre-treat the surface of the liquid cooling pipe 65 to enhance the condensation effect, an external air source applies air pressure to the inside of the annular negative pressure airbag 7105 through the one-way valve. After the annular negative pressure airbag 7105 deforms, the hydrophilic modification reagent stored inside is squeezed into the annular spray hose 7106. The reagent is released through the spray nozzle of the annular spray hose 7106 and evenly coated on the outer surface of the liquid cooling pipe 65, forming a hydrophilic film on the surface of the liquid cooling pipe 65 to improve the subsequent condensation efficiency.
