Description

Technical Field

[0001] This application relates to power grid connection equipment, and more particularly to a JP cabinet for condensation diversion. Background Technology

[0002] JP cabinets (integrated distribution boxes) are key equipment installed on the low-voltage side of outdoor transformers in power distribution networks, undertaking comprehensive functions such as power distribution, metering, protection, and capacitor compensation. To ensure the heat dissipation requirements of internal components such as circuit breakers, busbars, and capacitors, ventilation holes are usually opened on the side walls and top cover of the cabinet, relying on natural air convection to dissipate the operating heat outside the cabinet.

[0003] However, this "vented heat dissipation" structure has inherent defects in outdoor high humidity environments: when humid air rich in moisture enters the cabinet through the heat dissipation holes, or when condensation forms on the cold cabinet top, inner wall and side wall due to the temperature difference between day and night, water droplets will drip directly onto the surface of live components, causing a sudden drop in insulation resistance, corrosion of metal parts, and in severe cases, short circuits, leakage, or even arc explosion accidents.

[0004] To address the aforementioned condensation problem, the industry has proposed various technical solutions, mainly including the following categories: Category 1: Active Dehumidification Solution. This solution uses a semiconductor cooling chip, condenser plate, and scraping mechanism to pre-treat the high-humidity air entering the cabinet, causing moisture to condense on the condenser plate surface before being discharged. This type of solution relies on active components such as the cooling chip, drive motor, and control system, resulting in high power consumption, numerous potential failure points, and frequent maintenance. It is unsuitable for large-scale deployment of ordinary outdoor JP cabinets. The second type is the heating and evaporation method. This method uses a heater to evaporate the condensation into water vapor, which is then removed by a dehumidifier. This method is energy-intensive, and the heating only increases the surface temperature without reducing the absolute humidity, thus only addressing the symptoms, not the root cause. Furthermore, there is a risk of condensation recurring after the heating plate stops working.

[0005] The third type: Passive drainage solution. Rigid components such as guide plates and channels are installed inside the cabinet to guide condensate to the drain outlet. This type of solution does not require an external power source, but it has the following drawbacks: First, the guide plates and channels are rigid, independent components, and gaps exist at the assembly interface with the inner wall of the cabinet, allowing condensate to leak through the interface; second, the drainage structure has a fixed geometry, which cannot adapt to the dynamic process of condensate randomly forming and rapidly rolling down the inner wall of the cabinet top, and when the water droplets flow too fast, they may overflow the edge of the channel and drip directly onto electrical components; third, the drainage structure is mostly integrated into the cabinet, and if it fails or needs upgrading, the cabinet must be cut and re-welded, making the modification of existing JP cabinets difficult and costly.

[0006] Category 4: Moisture-absorbing material solution. This involves placing desiccant packets or moisture-absorbing sheets inside the cabinet. This solution has limitations in terms of moisture absorption capacity, requires frequent replacement, and struggles to effectively manage and drain condensation from the inner wall of the cabinet top.

[0007] In summary, existing technologies suffer from the following technical problems: active solutions (dehumidification and heating) consume high power and require frequent maintenance; passive flow-guiding solutions, using a single material or single-layer structure, cannot simultaneously address both the "interception" and "guidance" functions of condensate, resulting in condensate potentially overflowing the flow-guiding boundary and dripping onto live components; and the flow-guiding structures are often welded and integrated with the cabinet, lacking modular design, necessitating cabinet cutting for retrofitting existing JP cabinets, leading to high retrofitting costs. Therefore, a technical solution that can simultaneously address these problems is urgently needed. Summary of the Invention

[0008] This application provides a JP cabinet for condensation diversion, which aims to solve the technical problems of high power consumption, frequent maintenance, difficulty in modification due to the integration of diversion structure in existing JP cabinet anti-condensation solutions, and the inability of a single material to simultaneously achieve the functions of interception and diversion.

[0009] The above-mentioned objective of this invention is achieved through the following technical solutions: A JP cabinet includes a cabinet body with a drainage hole on the bottom surface of the cabinet body, and also includes a condensation guiding module, which includes a horizontal guiding strip, a top guiding membrane and a vertical drainage strip. The horizontal guide strips are located on the inner wall of the side of the cabinet, and there are multiple of them, which are spaced apart in the vertical direction; the horizontal guide strips include a second adhesive layer, a second waterproof base layer, a first water guiding layer, and a first fast water guiding layer stacked in sequence, and the second adhesive layer is bonded and fixed to the inner side wall of the cabinet. The top drainage membrane is located on the inner top surface of the cabinet and includes a third adhesive layer, a third waterproof base layer, a second rapid water-guiding layer, and a second water-guiding layer stacked in sequence. The third adhesive layer is bonded and fixed to the inner side wall of the cabinet. The vertical drainage strip is located on the inner wall of the side of the cabinet and includes a first drainage layer, a second drainage layer, a first waterproof base layer, and a first adhesive layer stacked in sequence. The first adhesive layer is bonded to the inner wall of the cabinet. The second drainage layer at the upper end of the vertical drainage strip is connected to the second rapid water guiding layer of the top guide membrane. The vertical drainage strip and the horizontal guide strip are connected at their staggered positions through the first drainage layer, the second drainage layer and the first rapid water guiding layer. The lower end of the vertical drainage strip is suspended above the bottom surface of the cabinet. The first and second rapid water-conducting layers are ultra-fine glass fiber layers, which are composed of a plurality of glass fibers arranged in a disordered manner. Capillary gaps are formed between adjacent glass fibers. The diameter of the glass fibers is 0.5-3μm, the width of the capillary gaps between adjacent glass fibers is 0.1-10μm, and the capillary rise height is ≥150mm. The first and second drainage layers are made of glass fiber nonwoven fabric, with the glass fibers mainly oriented vertically for drainage.

[0010] By adopting the above technical solution, a condensation guiding module is installed on the inner wall of the JP cabinet. This module consists of horizontal guiding strips, a top guiding membrane, and vertical drainage strips, forming a three-dimensional guiding network. Multiple horizontal guiding strips are spaced vertically on the inner wall of the cabinet side, and each horizontal guiding strip independently undertakes the task of intercepting condensation in its height area. The top guiding membrane fully covers the inner wall of the top of the cabinet and is responsible for collecting water droplets condensed on the top of the cabinet. The vertical drainage strips serve as the main vertical channels. The second drainage layer at the top of the vertical drainage strips is connected to the second rapid water guiding layer of the top guiding membrane. The staggered positions of the vertical drainage strips and the horizontal guiding strips are connected by the first drainage layer, the second drainage layer, and the first rapid water guiding layer. The lower end is suspended above the bottom surface of the cabinet, thereby converging all horizontally intercepted water flows into the same vertical channel and guiding them to the drainage outlet. This structure allows condensation formed at any location on the inner wall of the cabinet to be intercepted nearby, converged layer by layer, and discharged centrally within the shortest path, preventing condensation from dripping freely inside the cabinet or flowing disorderly along the wall to live components. Within the internal structure of the transverse guide strip and the top guide membrane, condensed water undergoes a progressive migration process of "transient buffering—capillary suction—rapid diversion." The condensed water first contacts the first water-guiding layer of the transverse guide strip or the second water-guiding layer of the top guide membrane. Both layers decelerate and temporarily store the water flow through the microporous structure of the hydrophilic polyurethane foam, preventing the water from rapidly rolling over the guide boundary. Subsequently, driven by capillary pressure difference, the water is drawn into the ultrafine glass fiber capillary network of the first or second rapid water-guiding layer. Both the first and second rapid water-guiding layers are composed of disordered ultrafine glass fibers with a diameter of 0.5-3 μm. The arrangement of the fibers creates capillary gaps with an average width of 0.1-10 μm and a capillary rise height of ≥150 mm, generating a strong capillary suction force that instantly captures water from the secondary water-conducting layer and rapidly transports it horizontally to the vertical drainage strip. The vertical drainage strip includes a first drainage layer and a second drainage layer, both of which are made of glass fiber nonwoven fabric with the fibers mainly oriented vertically, allowing the water flow to migrate downwards to the drainage holes under the combined action of gravity and capillary force. The entire flow guidance process relies entirely on the inherent capillary properties of the material and is driven by the gravitational field, requiring no external energy or moving parts, thus achieving zero-power, maintenance-free passive condensation control. Therefore, this application, through the above structural design, not only solves the problem that existing rigid guide plates can only collect condensation locally and cannot adapt to large-area random condensation on the top of the cabinet, but also solves the functional contradiction that a single material or single-layer structure cannot simultaneously take into account both "interception" and "dredging" through the division of labor and cooperation of multiple composite materials; at the same time, the guide structure is decoupled from the integrated manufacturing of the cabinet into an independent module, and is installed by adhesive layer without changing the original structure of the cabinet, so that the anti-condensation upgrade of existing JP cabinets does not require cutting the cabinet or re-testing the type.

[0011] Optionally, the thickness of the first rapid water-conducting layer is 0.1-0.3 mm, and the thickness of the second rapid water-conducting layer is 0.2-0.4 mm.

[0012] By adopting the above technical solution, the thickness parameter is designed differently according to the water-guiding load borne by the transverse guide strip and the top guide membrane respectively. The transverse guide strip mainly intercepts condensation on the inner wall of the cabinet side. Its single-point condensation is relatively small and dispersed. Therefore, the first rapid water guiding layer is thinner at 0.1-0.3mm. While ensuring sufficient water guiding cross-sectional area, it minimizes the material's own obstruction of water flow, allowing water to migrate quickly in the capillary network with a shorter path. At the same time, it helps to reduce the overall thickness of the module and avoids occupying too much electrical space inside the cabinet. The top guide membrane fully covers the inner wall of the cabinet top and bears the collection of condensation on the cabinet top. The condensation is large and concentrated. Therefore, the second rapid water guiding layer is thicker at 0.2-0.4mm, providing a larger water guiding cross-sectional area and higher water holding capacity. It ensures that the capillary suction capacity will not be lost due to local saturation under high flow conditions, and maintains the continuous and efficient transmission of condensation on the top. Through the aforementioned thickness-differentiated design, both the first and second rapid water-conducting layers achieve optimal water-conducting performance within their respective working areas. The synergistic cooperation in thickness ensures that the entire flow system maintains efficient water-conducting capacity across different condensation load areas. This avoids redundancy and waste in thin-layer areas while preventing water-conducting bottlenecks in thick-layer areas. The first and second rapid water-conducting layers are adapted to the different water-conducting load requirements of the transverse guide strip and the top guide membrane, respectively. While ensuring water-conducting efficiency, the overall module thickness is optimized, balancing flow performance and spatial adaptability, thereby improving the reliability and engineering practicality of the JP cabinet anti-condensation system.

[0013] Optionally, the first and second water-conducting layers are hydrophilic polyurethane foam with a thickness of 0.5-0.8 mm; the surface of the first water-conducting layer facing the first rapid water-conducting layer has a pore size gradient structure, with the surface pore size gradually changing to 20-50 μm; the surface of the second water-conducting layer facing the second rapid water-conducting layer has a pore size gradient structure, with the surface pore size gradually changing to 20-50 μm.

[0014] By employing the above technical solution, a capillary force gradient decreasing from deep large pore size (50-200μm) to surface small pore size (20-50μm) is constructed inside both the transverse guide strip and the top guide membrane. When condensed water contacts the surface of the first or second water-conducting layer, the microporous structure of the hydrophilic polyurethane foam wets the surface and draws the water into the micropores within 1 second. After entering the deep large pore size region, the water experiences relatively small capillary binding force. As the water migrates towards the surface, the pore size gradually decreases, and the capillary force gradually... The system enhances the capillary suction force field, which extends from the deep layer to the surface. This force field causes water to spontaneously migrate from the deep layer to the surface, generating a strong capillary pressure difference in the small-pore area of ​​the surface layer. This actively pushes the water to the interface with the first or second rapid water-conducting layer, where it awaits suction from the next layer. At the same time, since the pore size of the surface layer is only 20-50 μm, its instantaneous water retention capacity is stronger than that of the deep layer, which acts as a deceleration and temporary storage mechanism, preventing water from rapidly penetrating and dripping directly within the first or second water-conducting layer. Through the above structure, both the first and second water-conducting layers achieve synergistic layered functions of "deep water collection, surface pressurization, and directional transmission." The deep, large-aperture region is responsible for rapidly absorbing condensate water rolling off the inner wall of the cabinet top or side, providing sufficient volume to temporarily store transient water flow. The surface, small-aperture region acts as a capillary pressurization layer, transforming water from passive reception to active output, ensuring that water can overcome interfacial resistance and enter the first or second rapid water-conducting layer. This gradient design enables the dominant migration of water within the first and second water-conducting layers. The direction is locked from the deep layer through the surface to the corresponding fast-flowing aquifer. During reverse migration, since the capillary force decreases with the increase of pore size, the reverse migration resistance is significantly greater than that in the forward direction, thus realizing the unidirectional dominant flow of water at the physical level. At the same time, since the gradient transition is gradual rather than abrupt, the reverse channel is not completely blocked. Under special working conditions where drainage of the first or second fast-flowing aquifer is obstructed, water can still flow back along the gradient to the deep region of the first or second aquifer for temporary storage, avoiding the formation of a "dead water zone" at the interface. Ultimately, both the first and second water-conducting layers are transformed from passively absorbent materials with uniform pore size in existing technologies into active water-conducting media with directional driving capabilities. The secondary water-conducting layers in the transverse guide strips and the top guide membrane work together to not only achieve rapid absorption and deceleration of condensate on the top and sides of the cabinet, but also ensure the directional transfer of water to their respective rapid water-conducting layers through capillary gradient. At the same time, a reverse migration channel is retained to prevent interface blockage in case of drainage abnormalities, which significantly improves the overall treatment efficiency and operational reliability of the JP cabinet anti-condensation system.

[0015] Optionally, the first water-conducting layer and the first rapid water-conducting layer are connected by anchoring with discrete dot-shaped adhesive and supplemented by thermo-pressing mechanical interlocking, and the second water-conducting layer and the second rapid water-conducting layer are connected by anchoring with discrete dot-shaped adhesive and supplemented by thermo-pressing mechanical interlocking.

[0016] By adopting the above technical solution, except for the adhesive dot anchoring area, there is no adhesive barrier in the other interface areas. The micropores of the secondary water-conducting layer and the capillary gaps of the rapid water-conducting layer are in direct physical contact, forming an open capillary channel network. This open capillary channel network accounts for more than 70% of the interlayer interface area. The hot-pressing process further promotes the micro-melting flow of the surface layer of the secondary water-conducting layer, enabling the foam surface layer to form a shallow interlock with the glass fiber even in non-adhesive dot areas. This enhances the overall connection strength without clogging the capillary channels. This connection method is implemented simultaneously in the transverse guide strip and the top guide film, ensuring that the secondary water-conducting layer and the rapid water-conducting layer on the sides and top of the cabinet have the same interface structure, ensuring the consistency and reliability of the interlayer connection of the entire guide system. The interlayer interface forms an interface structure of "strong point connection and area capillary passage". The adhesive dot anchoring area provides the main The required mechanical connection strength ensures that the two layers will not peel off due to vibration, temperature changes, or water erosion during long-term operation; the molten interlocking zone forms an auxiliary connection around the adhesive dots, further enhancing the integrity of the interface; while the open capillary zone, accounting for more than 70% of the interface area, completely preserves the capillary continuity between the secondary water-conducting layer and the rapid water-conducting layer, allowing water to migrate freely in both directions between the two layers; in actual operation, when condensate enters the rapid water-conducting layer from the secondary water-conducting layer, it does not need to pass through any adhesive barrier and can be transferred directly through the open capillary zone; when the drainage of the rapid water-conducting layer is blocked, the water can also flow back to the secondary water-conducting layer along the same path for temporary storage, avoiding "dead water zones" or water conduction interruptions at the interface; this "point-surface" combined interface design allows the originally contradictory requirements of connection strength and capillary unobstructed flow to be met simultaneously; Therefore, this application enables both the connection strength and capillary permeability to be met between the first water-conducting layer and the first rapid water-conducting layer, and between the second water-conducting layer and the second rapid water-conducting layer. This connection method not only ensures that the interlayer peel strength meets the mechanical reliability requirements for long-term operation, but also retains more than 70% of the open capillary channel area, ensuring the efficient transfer and bidirectional migration of condensate between the two layers, significantly improving the structural stability and water-conducting reliability of the JP cabinet anti-condensation system during long-term operation.

[0017] Optionally, the thickness of the first drainage layer and the second drainage layer is 1.2-2 mm.

[0018] By adopting the above technical solution, sufficient water-guiding cross-sectional area and water-holding capacity are provided for the vertical drainage strip. As the vertical main channel of the entire three-dimensional flow guiding network, the vertical drainage strip needs to simultaneously receive condensate collected from the top of the cabinet by the top flow guiding membrane and condensate intercepted from the sides by the horizontal flow guiding strips of each layer. Multiple water flows converge within the vertical drainage strip and then migrate downwards. If the drainage layer is too thin and the water-guiding cross-sectional area is insufficient, local saturation is likely to occur when multiple water flows rush in simultaneously, causing the capillary channels to be filled with water and lose their ability to continue pumping. This can lead to water accumulation at the top of the vertical drainage strip or even overflow into the horizontal flow guiding strips. By setting the thickness of the first and second drainage layers to 1.2-2mm, their water-guiding cross-sectional area is significantly larger than that of the horizontal water-guiding layer, which can easily withstand the instantaneous convergence flow of multiple water flows. This design ensures that even during peak condensation periods, there will be no drainage bottleneck due to insufficient water-conducting capacity. Simultaneously, this thickness, combined with the vertically oriented glass fiber structure defined in claim 1, allows water to migrate rapidly downwards along the oriented capillary channels under the combined action of gravity and capillary force. The ample volume provided by the thickened layer ensures that the drainage strip will not lose its water-conducting capacity due to local saturation. Even if the lower end of the drainage strip is briefly immersed in water, the upper part can still continuously draw water through capillary force. Therefore, through the design of the aforementioned thickness parameters, this application provides sufficient water-conducting capacity for both the first and second drainage layers while maintaining flexibility and adhesion. This, combined with the directional fiber arrangement, effectively solves the drainage bottleneck problem when multiple water flows converge, significantly improving the drainage reliability and overall anti-condensation effect of the vertical drainage strip under high condensation conditions.

[0019] Optionally, the transverse guide strip includes two inclined connecting segments and two horizontally extending segments. The lower ends of the two inclined connecting segments are connected, and the upper ends of each of the two inclined connecting segments are connected to a horizontal segment. The transverse guide strip is connected to the vertical drainage strip at the lower end connection of the two inclined connecting segments.

[0020] By adopting the above technical solution, the horizontal guide strip forms a three-section guide path of "horizontal collection - inclined guide - node convergence" along its length. When condensation forms on the inner wall of the cabinet side, it is first intercepted by the horizontal section and migrates to both ends horizontally. After the water reaches the end of the horizontal section, it enters the inclined connecting section. Since the inclined connecting section is inclined downward towards the convergence node, the water flow converges towards the center along the inclined connecting section under the drive of gravity. After the multiple water flows merge at the convergence node, they directly enter the vertical drainage strip through this node. This structure concentrates the ends of multiple guide strips that may have been scattered in multiple places and connected to the vertical drainage strip into a unified connection point, simplifying the connection structure between the guide strip and the vertical drainage strip. At the same time, by utilizing the inclined guiding effect of the inclined connecting section, the water flow naturally converges towards the center under the assistance of gravity, avoiding the stagnation or backflow of water at the end of the horizontal section due to the sudden change in flow direction, ensuring that all intercepted condensation can smoothly complete the direction conversion from horizontal guide to vertical drainage. Therefore, the horizontal guide strip is transformed from the straight single-end connection structure in the existing technology into a symmetrical branching and converging structure, so that the water flow converges from both ends to the center and enters the vertical drainage strip in a unified manner. This shortens the migration path of water flow on one side, and at the same time merges multiple connection points into one, reducing the flow resistance and leakage risk at the connection points. This significantly improves the confluence efficiency of condensate from the horizontal guide strip to the vertical drainage strip and the overall flow guidance reliability.

[0021] Optionally, at the intersection of the vertical drainage strip and the horizontal guide strip, the horizontal guide strip is partially stripped of all layers except the first rapid water guiding layer, and the first rapid water guiding layer is sandwiched between the first drainage layer and the second drainage layer.

[0022] By adopting the above technical solution, a sandwich-like interlayer structure of "drainage layer - rapid water guiding layer - drainage layer" is formed, eliminating the obstruction of water flow path by other layers in the transverse guide strip. This allows the ultra-fine glass fiber capillary network in the first rapid water guiding layer to directly and physically contact the oriented glass fiber capillary channels in the first and second drainage layers, achieving seamless cross-layer connection of capillary channels. After condensed water migrates from the horizontal section of the transverse guide strip to the collection node via the oblique connecting section, it directly enters the capillary network of the first and second drainage layers from the first rapid water guiding layer without needing to cross any intermediate interface or overcome additional interface resistance. This significantly reduces the flow loss of water at the connection point, ensuring efficient and unobstructed transfer of condensed water from the transverse guide strip to the vertical drainage strip. Therefore, the connection between the transverse guide strip and the vertical drainage strip eliminates redundant interfaces, achieving direct connection of capillary channels. This fundamentally solves the water guiding bottleneck problem at the connection point, significantly improving the confluence efficiency of condensed water from the transverse guide strip to the vertical drainage strip and the overall flow guiding reliability.

[0023] Optionally, the outermost layer of the horizontal guide strip and the vertical drainage strip may also include a water-permeable and air-permeable layer.

[0024] By adopting the above technical solution, the film acts as a physical barrier, completely enclosing the ultrafine glass fibers of the first rapid water-conducting layer in the horizontal guide strip and the glass fibers of the first and second drainage layers in the vertical drainage strip. This effectively prevents the fibers from falling into the cabinet space or drifting into the air due to vibration or airflow disturbance during transportation, installation, or long-term operation, thus avoiding the risk of glass fibers irritating the respiratory tract of maintenance personnel and causing pollution or short circuits to the precision electronic components inside the cabinet.

[0025] In summary, this application has at least the following beneficial effects: 1. A three-dimensional flow guiding network is constructed through horizontal guide strips, a top flow guiding membrane, and vertical drainage strips to achieve nearby interception, layer-by-layer convergence, and centralized discharge of condensate. The entire flow guiding process relies entirely on capillary action and gravity drive, requiring no external energy or moving parts, achieving zero power consumption, maintenance-free operation, and extending the module's design life; 2. The first water-conducting layer and the first rapid water-conducting layer are anchored by discrete dot-shaped adhesive and connected by thermo-press mechanical interlocking, which optimizes the adhesive application rate, improves the peel strength, and increases the proportion of open capillary channels, allowing water to migrate bidirectionally between the two layers; the vertical drainage strip adopts a thickened glass fiber layer with vertically oriented fibers, and works with a one-way valve at the lower end to achieve efficient directional drainage and prevent external moisture from invading in the reverse direction; 3. The module is attached to the inner wall of the cabinet as an independent component through an adhesive layer. It does not penetrate the cabinet wall, does not change the original structure of the cabinet, and does not affect the protection level, temperature rise and electrical safety indicators.

[0027] As attached Figure 1 As shown, a JP cabinet includes a cabinet body 1 and a condensation diversion module 2 installed inside the cabinet body 1. One side of the cabinet body 1 is open for equipment installation and cabinet door installation.

[0028] The condensation diversion module 2 is installed on the top surface and the other three inner sides inside the cabinet 1. The condensation diversion module 2 includes vertical drainage strips 21, horizontal diversion strips 22, and a top diversion membrane 23.

[0029] As attached Figure 2 As shown, vertical drainage strips 21 are provided on all three vertical inner sides of the cabinet 1.

[0030] The vertical drain strip 21 is installed vertically and attached to the inside of the cabinet 1. The upper end of the vertical drain strip 21 is flush with the top surface of the cabinet 1, and its lower end extends downwards, leaving a gap of 1.5-2.5cm between it and the bottom surface of the cabinet 1. The lower ends of the vertical drain strip 21 are cut into V-shapes on both sides. The width of the vertical drain strip 21 is 3-3.5cm.

[0031] As attached Figure 3 As shown, the vertical drainage strip 21 itself has a multi-layer structure, consisting of a first water-permeable and breathable layer 211, a first drainage layer 212, a second drainage layer 213, a first waterproof base layer 214, and a first adhesive layer 215 stacked sequentially. The first adhesive layer 215 is bonded to the inner wall of the cabinet 1, and the first water-permeable and breathable layer 211 faces the center of the interior of the cabinet 1.

[0032] The first water-permeable and air-permeable layer 211 is a commercially available flame-retardant PET microporous film coating with a thickness of 0.02 mm and a pore size of >100 μm.

[0033] The first drainage layer 212 and the second drainage layer 213 are the same, using commercially available glass fiber nonwoven fabric with a thickness of 1.2-2 mm, which is 1.8 mm in this embodiment. The glass fibers in the first drainage layer 212 and the second drainage layer 213 are mainly oriented vertically to form oriented capillary channels consistent with the direction of gravity.

[0034] The first waterproof base layer 214 uses commercially available flame-retardant polyethylene terephthalate film with a thickness of 0.05mm.

[0035] The first adhesive layer 215 uses commercially available acrylic double-sided pressure-sensitive tape with a thickness of 0.1 mm and a temperature resistance range of -40℃ to +120℃.

[0036] The first water-permeable and air-permeable layer 211 and the first drainage layer 212 are joined by hot-pressing and melting. The first water-permeable and air-permeable layer 211 is covered on one side of the first drainage layer 212. The entire structure is hot-pressed at a temperature of 270~290℃ and pressured to more than 120Pa. This softens a portion of the first water-permeable and air-permeable layer 211 and embeds it into the gaps between the glass fibers on the surface of the first drainage layer 212 to form a physical interlock within the area. After hot pressing, the structure is cooled to room temperature, and the first water-permeable and air-permeable layer 211 and the first drainage layer 212 are combined into one.

[0037] The first drainage layer 212 and the second drainage layer 213 are connected by discrete dot adhesive anchoring and thermo-press mechanical interlocking. Except for the adhesive dot anchoring area, the capillary gaps of the first drainage layer 212 and the second drainage layer 213 are directly connected to form a continuous capillary channel network.

[0038] The second drainage layer 213 and the first waterproof base layer 214 are connected by applying adhesive evenly and then hot-pressing. The adhesive is applied evenly to the surface of the first waterproof base layer 214 (10g / m², do not apply too much), and then the second drainage layer 213 is placed on top of it. The mixture is then hot-pressed at 80~100℃ and 0.1~0.2MPa for 20~30 seconds to cure.

[0039] The first waterproof base layer 214 and the first adhesive layer 215 are directly bonded and fixed by the double-sided adhesive of the first adhesive layer 215.

[0040] As attached Figure 2 As shown, there are multiple horizontal guide strips 22, which are arranged at intervals from top to bottom with a spacing of 10-15cm.

[0041] As attached Figure 4As shown, the transverse guide strip 22 has a layered structure, which includes a second water-permeable and breathable layer 221, a first rapid water-conducting layer 222, a first water-conducting layer 223, a second waterproof base layer 224, and a second adhesive layer 225 stacked sequentially. The second adhesive layer 225 is bonded to the inner wall of the cabinet 1, and the second water-permeable and breathable layer 221 faces the center of the interior of the cabinet 1.

[0042] The second water-permeable and air-permeable layer 221 is a flame-retardant PET microporous film coating with a thickness of 0.02 mm and a pore size of >100 μm.

[0043] The first rapid water-conducting layer 222 is a commercially available ultrafine glass fiber layer, composed of a plurality of glass fibers of various diameters arranged in a disordered manner, with capillary gaps formed between adjacent glass fibers. The diameter distribution range of the glass fibers is 0.5-3μm, and the average width of the capillary gaps formed between adjacent glass fibers is 0.1-10μm. The thickness of the first rapid water-conducting layer 222 is 0.1-0.3mm, and in this embodiment it is 0.2mm. The capillary rise height of the first rapid water-conducting layer 222 is ≥150mm.

[0044] The first water-conducting layer 223 is a commercially available hydrophilic polyurethane foam with a thickness of 0.5-0.8 mm, and in this embodiment, it is 0.6 mm. The surface of the first water-conducting layer 223 facing the first rapid water-conducting layer 222 has a pore size gradient structure, with the surface pore size gradually changing to 20-50 μm.

[0045] The second waterproof base layer 224 uses commercially available flame-retardant polyethylene terephthalate film with a thickness of 0.05mm.

[0046] The second adhesive layer 225 uses commercially available acrylic double-sided pressure-sensitive tape with a thickness of 0.1 mm and a temperature resistance range of -40℃ to +120℃.

[0047] The connection between the second permeable and breathable layer 221 and the first rapid water-conducting layer 222 is achieved through hot-pressing fusion bonding. The second permeable and breathable layer 221 is placed over one side of the first rapid water-conducting layer 222, and the entire structure is hot-pressed at a temperature of 270-290°C and pressured to over 120 Pa. This softens a portion of the second permeable and breathable layer 221, embedding it into the gaps between the glass fibers on the surface of the first rapid water-conducting layer 222, forming a physical interlocking effect over a surface area. After hot pressing and cooling to room temperature, the second permeable and breathable layer 221 and the first rapid water-conducting layer 222 are integrally bonded.

[0048] The connection between the first rapid water-conducting layer 222 and the first water-conducting layer 223 is achieved by anchoring with discrete dot-shaped adhesive and supplementing with thermo-pressing mechanical interlocking, with a dot-matrix adhesive application rate of 5%-10%. Except for the adhesive dot anchoring area, the micropores of the first water-conducting layer 223 are directly connected to the capillary gaps of the first rapid water-conducting layer 222 at the interlayer interface, forming a continuous capillary channel network. The continuous capillary channel network accounts for more than 70% of the interlayer interface area.

[0049] The first water-conducting layer 223 and the second waterproof base layer 224 are connected by a flame-retardant adhesive being applied evenly and then hot-pressed. The adhesive is applied evenly to the surface of the second waterproof base layer 224 (coating amount 5g / m²), and then the first water-conducting layer 223 is placed on top of it. The mixture is then hot-pressed at 80~100℃ and 0.1~0.2MPa for 20~30s to cure.

[0050] The second waterproof base layer 224 and the second adhesive layer 225 are directly bonded and fixed by the double-sided adhesive of the second adhesive layer 225.

[0051] As attached Figure 2 As shown, the transverse guide strip 22 is divided into a horizontal segment 226 and an inclined segment 227 along the horizontal direction, with two of each. The horizontal segment 226 and the inclined segment 227 are integrally formed from a single piece of multi-layered structural material.

[0052] Horizontal sections 226 are located at both ends of the transverse guide strip 22, and inclined sections 227 are located between the two horizontal sections 226. The two inclined sections 227 are inclined downward and symmetrically arranged. The upper end of the inclined section 227 is connected to the end of one horizontal section 226, and the lower end of the inclined section 227 is connected to the lower end of the other inclined section 227.

[0053] As attached Figure 2 As shown, the horizontal water guide strip is connected to the vertical drainage strip 21 at the lower end connection point of the two inclined sections 227.

[0054] As attached Figure 5 As shown, the lower ends of the two inclined sections 227 are partially peeled off by a tool (such as a scaffolding knife) to remove the second permeable and breathable layer 221, the first water-conducting layer 223, the waterproof base layer and the adhesive layer. Thin mica sheets can be pre-attached to both sides of the first fast water-conducting layer 222 at this point to prevent the multi-layer structure from sticking together.

[0055] Cut open the side of the vertical drainage strip 21 to partially separate the connection interface between the first drainage layer 212 and the second drainage layer 213. Then pass the horizontal water guide strip between the first drainage layer 212 and the second drainage layer 213 so that the lower end connection point of the two inclined sections 227 is sandwiched between the first drainage layer 212 and the second drainage layer 213 by a separate first fast water guide layer 222.

[0056] Because the thicknesses of the horizontal water guide strips and the vertical drainage strips 21 are different, the length of the first rapid water guide layer 222 exposed is greater than the width of the vertical drainage strips 21, and the excess part is bent and attached to the side of the second drainage layer 213.

[0057] As attached Figure 2 and Figure 6 As shown, the number of horizontal water guide strips on the vertical sidewalls of different cabinets 1 is equal, and their heights correspond one-to-one.

[0058] The transverse water-guiding strips of the same height are connected at the ends of horizontal segments 226. The connection method involves removing the second permeable and breathable layer 221 and the second rapid water-guiding layer 233 from the end of one horizontal segment 226, and removing the adhesive layer, waterproof base layer, and second water-guiding layer 232 from the end of the other horizontal segment 226. These are then overlapped on the first horizontal segment and bonded together with adhesive. The partial removal lengths of the two horizontal segments 226 are the same, ensuring a perfect fit after overlap.

[0059] As attached Figure 2 and attached Figure 7 As shown, the top drainage membrane 23 covers the entire inner top surface of the cabinet 1. The top drainage membrane 23 includes a third water-permeable and breathable layer 231, a second water-guiding layer 232, a second rapid water-guiding layer 233, a third waterproof base layer 234, and a third adhesive layer 235, which are stacked sequentially. The third adhesive layer 235 is bonded to the inner top surface of the cabinet 1, and the third water-permeable and breathable layer 231 faces downward.

[0060] The third water-permeable and air-permeable layer 231 is a flame-retardant PET microporous film coating with a thickness of 0.02 mm and a pore size of >100 μm.

[0061] The second water-conducting layer 232 is a commercially available hydrophilic polyurethane foam with a thickness of 0.5-0.8 mm, which is 0.6 mm in this embodiment. The surface of the second water-conducting layer 232 facing the second rapid water-conducting layer 233 has a pore size gradient structure, with the surface pore size gradually changing to 20-50 μm.

[0062] The second rapid water-conducting layer 233 is a commercially available ultrafine glass fiber layer, composed of a plurality of glass fibers of various diameters arranged in a disordered manner, with capillary gaps formed between adjacent glass fibers. The diameter distribution of the glass fibers ranges from 0.5 to 3 μm, and the average width of the capillary gaps formed between adjacent glass fibers is 0.1 to 10 μm. The capillary rise height of the second rapid water-conducting layer 233 is ≥150 mm, and the thickness of the second rapid water-conducting layer 233 is 0.2-0.4 mm, which is 0.3 mm in this embodiment.

[0063] The third waterproof base layer 234 uses commercially available flame-retardant polyethylene terephthalate film with a thickness of 0.05mm.

[0064] The third adhesive layer 235 uses commercially available acrylic double-sided pressure-sensitive tape with a thickness of 0.1 mm and a temperature resistance range of -40℃ to +120℃.

[0065] The connection between the third permeable and breathable layer 231 and the second water-conducting layer 232 is achieved by hot-pressing and melting composite.

[0066] The connection between the second rapid water-conducting layer 233 and the second water-conducting layer 232 is achieved by anchoring with discrete dot-shaped adhesive and supplementing with thermo-press mechanical interlocking, with a dot-matrix adhesive application rate of 5%-10%. Except for the adhesive dot anchoring area, the micropores of the second water-conducting layer 232 are directly connected to the capillary gaps of the second rapid water-conducting layer 233 at the interlayer interface, forming a continuous capillary channel network. The continuous capillary channel network accounts for more than 70% of the interlayer interface area.

[0067] The second rapid water-conducting layer 233 and the third waterproof base layer 234 are connected by a flame-retardant adhesive being applied evenly and then hot-pressed. The adhesive is applied evenly to the surface of the third waterproof base layer 234 (coating amount 5g / m²), and then the second water-conducting layer 232 is placed on top of it. The mixture is then hot-pressed at 80~100℃ and 0.1~0.2MPa for 20~30s to cure.

[0068] The third waterproof base layer 234 and the third adhesive layer 235 are directly bonded and fixed by the double-sided adhesive of the second adhesive layer 225.

[0069] As attached Figure 3 and Figure 7 As shown, the upper end of the vertical drainage strip 21 is inserted into the top water-guiding membrane. After peeling off the remaining layers except for the second drainage layer 213, the upper end of the vertical drainage strip 21 is inserted between the second rapid water-guiding layer 233 and the second water-guiding layer 232 of the top water-guiding membrane.

[0070] As attached Figure 8 As shown, a circumferential edge 11 is provided at the outer edge of the inner bottom surface of the cabinet 1. The circumferential edge 11 is arranged around the outer edge of the inner bottom surface and is spaced 2.5-3.5cm apart from the side surface, thus forming a square annular groove 12 between the circumferential edge 11 and the side surface of the cabinet 1.

[0071] As attached Figure 9 and attached Figure 10 As shown, drainage holes 13 are opened on the bottom surface of all four sides of the surrounding groove 12. The drainage holes 13 are long rectangular holes. A one-way drainage component 3 is embedded in the drainage hole 13.

[0072] As attached Figure 10 As shown, the one-way drainage assembly 3 includes a drainage trough 31, the upper end of which is inserted into the drainage hole 13 and is press-fitted into the drainage hole 13. The upper end of the drainage trough 31 is open, and the outer edge of the upper end opening of the drainage trough 31 is surrounded by a mounting edge 311. The bottom surface of the mounting edge 311 abuts against the bottom of the surrounding groove 12.

[0073] The drainage trough 31 has an internal cavity that is rectangular. Its inner bottom surface is divided into an inclined guide surface 312 and an arc-shaped guide surface 313 along a horizontal direction parallel to the interior of the adjacent cabinet 1. The inclined guide surface 312 slopes downward toward the arc-shaped guide surface 313, and the arc-shaped guide surface 313 descends along an arc-shaped trajectory toward the inclined guide surface 312. A water outlet hole 314 penetrating the bottom of the drainage trough is opened at the connection between the inclined guide surface 312 and the arc-shaped guide surface 313.

[0074] Hollow floats 32 are placed inside the drainage trough. The hollow floats 32 are made of rubber or plastic, and their diameter is larger than the diameter of the water outlet 314 but smaller than the width of the drainage trough. In addition, the hollow floats 32 can float naturally on the water surface.

[0075] The upper opening of the drainage channel is fitted with a cover plate 33, and the upper end of the cover plate 33 has a water inlet hole 331 for water supply. The width of the water inlet hole 331 is smaller than the diameter of the hollow float 32.

[0076] The mechanism of action and beneficial effects of this embodiment: After the condensate forms on the inner wall of the top and the inner wall of the side of the cabinet 1, it is first intercepted by the top guide film 23 and the horizontal guide strip 22. When condensed water comes into contact with the first water-conducting layer 223 or the second water-conducting layer 232, the microporous structure of the hydrophilic polyurethane foam provides transient buffering and deceleration for the water flow, preventing the water from rolling over the flow boundary rapidly. Subsequently, driven by the capillary force gradient formed by the pore size gradient structure, water spontaneously migrates directionally from the deep layer to the surface layer, and generates a strong capillary pressure difference in the small pore size region of the surface layer, actively pushing the water to the interface of the first rapid water-conducting layer 222 or the second rapid water-conducting layer 233. The ultra-fine glass fiber layer generates a capillary rise height of ≥150mm with its micron-level capillary gap, forming a capillary suction force much greater than that of the secondary water-conducting layer, instantly capturing the water and rapidly transmitting it horizontally to the vertical drainage strip 21. The glass fiber nonwoven fabric in the vertical drainage strip 21, with its fibers oriented vertically, guides water downwards into the enclosure groove 12 at the bottom of the cabinet under the combined action of gravity and capillary force. After the condensate in the surrounding trough 12 flows into the drainage trough 31, it causes the hollow float 32 to float, and the condensate flows out from the outlet 314.

[0077] The entire flow diversion process relies entirely on the inherent capillary properties of the material and is driven by the gravitational field, requiring no external power supply, sensors, or moving parts, thus achieving zero-power, maintenance-free passive condensation control.

[0078] The one-way drainage component 3 utilizes the cooperation of hollow float 32 with inclined guide surface 312 and arc-shaped guide surface 313 to achieve a one-way sealing function that allows water to flow from inside the cabinet to outside the cabinet and prevents external moisture from invading in the reverse direction.

[0079] In addition, the entire condensation diversion module 2 is attached to the inner wall of the cabinet 1 as an independent component through an adhesive layer. It does not penetrate the cabinet wall, does not change the original structure of the cabinet 1, and does not affect the protection level, temperature rise and electrical safety indicators. When upgrading existing JP cabinets, there is no need to cut the cabinet 1. When the module fails, it can be replaced as a whole, which significantly reduces the implementation threshold and operation and maintenance cost of anti-condensation upgrade.

[0080] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of protection claimed by the present invention, they are protected by patent law.
