Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an anti-condensation device, cabinet, and method for an air conditioning unit. Background Technology

[0002] With the rise of domestic industry, non-standard automated equipment electrical cabinets have been widely used in the industrial field. Due to the enclosed space inside the electrical cabinet and the high temperature in factories during summer, the heat generated by various wires and electrical components during operation accumulates. Over time, this heat can easily reach the protection temperature of the internal circuits of the electrical cabinet, affecting the normal use and lifespan of the electrical components. Therefore, air conditioning is needed to cool the interior of the electrical cabinet.

[0003] The applicant has discovered at least the following technical problems with the existing technology: Due to limitations such as site and space, electrical cabinet air conditioners are generally installed above electrical cabinets. However, during daily use of these air conditioners, condensation frequently occurs at the connection between the air conditioner's outlet and the electrical cabinet. Upon verification and investigation, it was found that this is caused by the lower temperature at the air conditioner's outlet and the higher operating temperature of the high-voltage power lines distributed above the electrical cabinet, resulting in a temperature difference between the two. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-condensation device, cabinet, and method for air conditioners in electrical cabinets, so as to solve the technical problem of condensation at the air outlet of air conditioners in electrical cabinets in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an anti-condensation device, comprising a gas collection component and a drainage pipe; wherein: the gas collection component is installed at the air conditioning outlet in the high-temperature area at the top of the equipment, and the first end of the drainage pipe is connected to the gas collection component, and the second end extends to the low-temperature area of ​​the equipment.

[0006] This invention collects low-temperature cold air from the air conditioner outlet through a gas collection device and directs the cold air to a higher-temperature low-temperature area (such as the bottom) inside the electrical cabinet through a drainage pipeline. This avoids the cold air from directly contacting the high-temperature power wires, thus blocking the conditions for the convergence of cold and heat at the source and eliminating the basis for condensation. At the same time, it utilizes the natural heat dissipation characteristics of the low-temperature area to improve the efficiency of cold air utilization and maintain the overall temperature balance of the electrical cabinet.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] As a further improvement of the present invention, a cold air diffuser connected to the second end is also included.

[0009] As a further improvement of the present invention, the cold air diffuser includes a cubic body and air guides disposed on different sides of the body; the air guides on different sides have different air outlet directions; and / or, the air guides on the same side have different air outlet directions.

[0010] The cold air diffuser of this invention evenly diffuses the centrally delivered cold air to the target area (such as the bottom of the electrical cabinet) through multi-sided air guides, avoiding excessive temperature gradients caused by local overcooling (for example, the temperature at a certain point suddenly drops below the dew point), and further reducing the risk of condensation.

[0011] As a further improvement of the present invention, the gas collection component includes a channel body and a mounting plate; wherein: The top opening of the trough body faces the air conditioner outlet; The mounting plate is disposed on one side of the groove body and is used for fixed connection with the equipment; The drainage pipe is connected to the inner cavity of the tank body.

[0012] The open design of the trough body of this invention ensures that all the cold air from the air conditioner outlet is efficiently collected, reducing the loss of cold energy; the mounting plate provides a standardized fixing interface, simplifying the installation process of the device and the top of the electrical cabinet and enhancing structural stability; the direct connection between the inner cavity and the drainage pipe ensures the shortest airflow transmission path, reduces flow resistance, and maintains the efficiency of cold air delivery.

[0013] As a further improvement of the present invention, a first connection port and a second connection port are respectively provided on opposite sides of the tank body; a third connection port is provided at the bottom of the tank body; The number of drainage pipes is three, and the three drainage pipes are respectively connected to the first connection port, the second connection port and the third connection port.

[0014] As a further improvement of the present invention, a 5mm gap is reserved between the drainage pipe and the top of the device.

[0015] As a further improvement of the present invention, the drainage pipeline is made of PVC steel wire hose.

[0016] As a further improvement of the present invention, the diameters of the first connection port, the second drainage port and the third drainage port are all 55mm.

[0017] As a further improvement of the present invention, the inner diameter of the drainage pipe is 51 mm and the wall thickness is 2 mm.

[0018] The multi-channel layout of this invention enables multi-directional distribution of cold air (such as left and right side walls + bottom vertical downward), covering high-temperature risk areas at different heights within the electrical cabinet (such as high-voltage wires usually distributed on the side walls, and the control module located at the bottom), and specifically solves the problem of local heat and cold convergence; the design of three pipelines balances the distribution of cold energy in each area, avoiding uneven pressure or local overcooling caused by excessive flow in a single pipeline.

[0019] As a further improvement of the present invention, the outer wall of the drainage pipe is wrapped with a heat insulation layer.

[0020] As a further improvement of the present invention, the heat insulation layer is made of nitrile foam.

[0021] As a further improvement of the present invention, the thickness of the heat insulation layer is 20 mm.

[0022] The insulation layer of this invention uses a low thermal conductivity material (nitrile sponge has an extremely low thermal conductivity) to block heat exchange between the outer wall of the pipeline and the surrounding high-temperature environment (such as the surface of a high-voltage power line), preventing water droplets from condensing on the surface of the cold air pipeline due to temperature differences; the softness of the nitrile sponge also has a buffering and protective function, reducing the risk of damage to the pipeline from external impacts.

[0023] As a further improvement of the present invention, it also includes a modularly configured positioning component, through which the drainage pipe is positioned on the inner wall of the device.

[0024] As a further improvement of the present invention, the positioning component includes a positioning plate and a protective cover; wherein: The positioning plate is used to position the drainage pipe on the top of the equipment; The protective cover is used to seal the drainage pipe on the side wall of the equipment.

[0025] The modular design of this invention allows for flexible adjustment of the specifications of the positioning plate / protective cover according to the size of the electrical cabinet, without the need for a customized overall device; the positioning plate ensures that the pipelines are firmly fixed at the top, preventing them from falling off due to vibration of the electrical cabinet; the protective cover protects the side wall pipelines from scratches during manual maintenance, while hiding the pipelines to improve the cleanliness of the interior of the electrical cabinet and indirectly extend the service life of the device.

[0026] The present invention provides an electrical cabinet, comprising an electrical cabinet box, an electrical cabinet air conditioner, and the aforementioned anti-condensation device; wherein: The top of the electrical cabinet box has a through-hole; The air outlet of the air conditioner in the electrical cabinet is directly opposite the through-hole; The gas collection component is installed at the through-hole; The end of the drainage pipe extends to the lower part of the electrical cabinet box.

[0027] The through-hole design of this invention enables unobstructed transmission of air conditioning cold air from the top air outlet to the air collection component; the layout of three pipes extending vertically along the left and right side walls and the middle covers the main high-temperature areas in the electrical cabinet (side wall power cables, bottom control module), and extends the cold air delivery path to the low-temperature area, avoiding direct contact with high-temperature surfaces; the symmetrical left and right + vertical middle distribution takes into account both space utilization and airflow uniformity.

[0028] As a further improvement of the present invention, the number of drainage pipes is three, of which two extend along the left and right side walls of the electrical cabinet box, and the third extends vertically downward along the middle of the electrical cabinet box.

[0029] This invention addresses the condensation problem at the air outlet of an electrical cabinet air conditioner caused by the convergence of hot and cold air. Through the synergistic effect of an innovative airflow guiding structure design, heat insulation protection measures, and an intelligent temperature control system, it fundamentally solves the potential condensation problem caused by the contact between the low-temperature cold air at the air outlet and the surface of the high-temperature power wires / components inside the cabinet when the traditional electrical cabinet air conditioner is installed on the top. At the same time, it optimizes the uniformity of temperature distribution inside the cabinet, improving the reliability and stability of the electrical equipment operation.

[0030] This invention provides a control method for temperature control of an electrical cabinet, wherein the electrical cabinet is equipped with an intelligent temperature control system, the intelligent temperature control system including a temperature and humidity sensor, a controller, and an air conditioning adjustment module; the method includes the following steps: Temperature acquisition: Real-time temperature and humidity data of key areas inside the electrical cabinet are collected using several temperature and humidity sensors; Data processing and analysis: The controller receives temperature and humidity data from the temperature and humidity sensor, compares it with the preset control temperature reference set, and makes a status judgment; the control temperature reference set includes dew point temperature threshold, air outlet temperature difference set value, and relative humidity. Dynamically adjust the air conditioner's outlet air temperature: Based on the status judgment result, the controller sends a command to the air conditioner's air conditioning adjustment module to adjust the air conditioner's outlet air temperature; It also includes alarm and feedback mechanisms: when the controller detects abnormal temperature or system failure, it will issue an alarm to the operator through an audible and visual alarm or a remote communication module, and record the abnormal data for subsequent analysis.

[0031] As a further improvement of the present invention, the controller receives temperature and humidity data acquired by the temperature and humidity sensor, compares it with a preset control temperature reference group, and performs a status judgment, including: When the temperature in a certain area inside the electrical cabinet is lower than the dew point temperature threshold and the relative humidity is high, the controller determines that there is a risk of condensation in that area. When the temperature difference between a certain area inside the electrical cabinet and the air outlet exceeds the set value for the air outlet temperature difference, the controller determines that there is a risk of hot and cold air mixing.

[0032] As a further improvement of the present invention, the controller sends a command to the air conditioning adjustment module of the air conditioner according to the judgment result to adjust the air conditioner outlet temperature, including: If it is determined that there is a risk of condensation, the air conditioner outlet temperature will be increased to reduce the temperature difference between hot and cold air and reduce the possibility of condensation. If it is determined that there is a risk of heat and cold converging, the air conditioner outlet temperature will be lowered to improve cooling efficiency.

[0033] Through selection calculations and experimental verification, the cold air flow rate of the drainage pipe of this invention can meet the temperature control requirements of the electrical cabinet per unit time without losing the cold air flow and cooling efficiency.

[0034] This invention replaces manual experience-based adjustments with real-time monitoring and intelligent decision-making, ensuring that the internal temperature and humidity of the electrical cabinet are always within a safe range; dynamic adjustment balances anti-condensation and cooling efficiency, avoiding energy waste caused by excessive cooling; and the remote alarm function shortens fault response time and improves operation and maintenance efficiency.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] Example 1 like Figures 1-10 As shown, the present invention provides an anti-condensation device, including an air collecting component 3 and a drainage pipe 4; wherein: the air collecting component 3 is installed at the air conditioner outlet 11 in the high-temperature area at the top of the equipment, for receiving and collecting the cold air blown out from the air conditioner outlet 11 of the electrical cabinet; the first end of the drainage pipe 4 is connected to the air collecting component 3, and the second end extends to the low-temperature area of ​​the equipment, specifically the bottom area of ​​the electrical cabinet.

[0040] This invention collects the low-temperature cold air from the air conditioner outlet 11 through the air collection component 3, and directs the cold air to the high-temperature low-temperature area (such as the bottom) inside the electrical cabinet through the diversion pipe 4. This avoids the cold air from directly contacting the high-temperature power wires, blocking the conditions for the convergence of cold and heat from the source and eliminating the basis for condensation. At the same time, it utilizes the natural heat dissipation characteristics of the low-temperature area to improve the efficiency of cold air utilization and maintain the overall temperature balance of the electrical cabinet.

[0041] In order to distribute the cold air to different areas of the electrical cabinet, this embodiment also includes a cold air diffuser 7 connected to the second end. The cold air diffuser 7 is added at the end of the drainage pipe 4 so that the cold air is evenly distributed under the electrical cabinet and avoids local overcooling.

[0042] Furthermore, such as Figure 10 As shown, the cold air diffuser 7 includes a cubic body 71 and air vents 72 disposed on different sides of the body 71. It should be noted that the shape of the body 71 is firstly determined by the size of the bottom space of the electrical cabinet 2, and in order to save costs and reduce the volume of the body 71, in this embodiment, the body 71 is a cubic structure with one end larger than the other and has four sides. In order to achieve multi-angle diffusion of cold air, the air vents 72 on different sides have different air outlet directions; and / or, the air vents 72 on the same side have different air outlet directions.

[0043] Specifically, such as Figure 10 As shown in the figure, the air vents 72 on the two visible sides are oriented in different directions, and the air vents 72 on the two invisible sides are symmetrically arranged with respect to the air vents 72 on the two visible sides. Figure 10 The air vent 72 located on the front side has an inclined air guide plate, and the inclination direction of the air guide plate is different, so that the air outlet direction of the air vent 72 on the same side is different.

[0044] Of course, in order to achieve full diffusion of cold air, the air guide can also be set to an adjustable angle structure.

[0045] The cold air diffuser 7 of the present invention uses multi-sided air guide ports 72 to evenly diffuse the centrally delivered cold air to the target area (such as the bottom of the electrical cabinet), avoiding excessive temperature gradient caused by local overcooling (for example, the temperature at a certain point suddenly drops below the dew point), and further reducing the risk of condensation.

[0046] like Figures 6-9 As shown, the gas collection component 3 includes a channel body 7131 and a mounting plate 32; wherein: The top opening of the trough body 7131 faces the air conditioner outlet 11. The trough body 7131 can collect the cold air discharged by the air conditioner and divert it to the low-voltage wires below the electrical cabinet through the drainage pipe 4. Since the low-voltage wires are at a low temperature when working, the cold air is less likely to condense after entering the electrical cabinet. Specifically, in this embodiment, the equipment is an electrical cabinet. Therefore, in order to connect the air conditioner outlet 11 of the electrical cabinet 1 with the interior of the electrical cabinet box 2, a through opening is provided on the top of the electrical cabinet box 2. The trough body 7131 is fixed to the top of the electrical cabinet box 2 by the mounting plate 32, and the top opening of the trough body 7131 faces the through opening. Mounting plate 32 is provided on one side of tank body 7131 for fixed connection with equipment; The drainage pipe 4 is connected to the inner cavity of the tank body 7131 and is used to directly drain the cold air in the tank body 7131 to the low temperature area at the bottom of the electrical cabinet box 2.

[0047] The opening design of the slot body 7131 of this invention ensures that all the cold air from the air conditioner outlet 11 is collected efficiently, reducing the loss of cold energy; the mounting plate 32 provides a standardized fixing interface, which simplifies the installation process of the device and the top of the electrical cabinet and enhances the structural stability; the direct connection between the inner cavity and the drainage pipe 4 ensures that the airflow transmission path is the shortest, reduces flow resistance, and maintains the efficiency of cold air delivery.

[0048] As an optional embodiment of the present invention, a first connection port and a second connection port are respectively provided on opposite sides of the groove body 7131; a third connection port is provided at the bottom of the groove body 7131. There are three drainage pipes 4, which are connected to the first connection port, the second connection port and the third connection port respectively.

[0049] Specifically, the three drainage pipes 4 include a first drainage pipe 41, a second drainage pipe 42, and a third drainage pipe 43; wherein the first drainage pipe 41 and the second drainage pipe 42 are connected to the first connection port and the second connection port respectively through flanges; the third drainage pipe 43 is connected to the third connection port through threads. By using the groove body 7131 to connect multiple drainage pipes 4, the present invention moves the air conditioner outlet 11 from the top of the electrical cabinet to the low-voltage wire area below the electrical cabinet, avoiding the convergence of hot and cold.

[0050] The anti-condensation device of this invention can effectively prevent condensation from adhering to the sheet metal on the top of the electrical cabinet, thus preventing electrical safety hazards, short circuits, and electric shocks, ensuring the reliability of the electrical cabinet operation; it also avoids the risk of condensation dripping and causing electrical component failure, reducing the cost of replacing electrical components and improving the overall stability of the electrical cabinet operation.

[0051] To prevent the sheet metal surface of the electrical cabinet 2 from scratching the drainage pipe 4 and to facilitate installation, a 5mm gap is reserved between the drainage pipe 4 and the top of the equipment. This facilitates installation and prevents the sponge from being scratched by burrs and protrusions on the sheet metal surface.

[0052] In this embodiment, the drainage pipe 4 is made of PVC steel wire hose, which has the characteristics of high strength, low temperature resistance, good sealing and flexibility. It can withstand the pressure of cold air discharged from the air conditioner 1 in the electrical cabinet, does not need to be replaced regularly, and meets the requirements of long-term use.

[0053] As a further improvement of the present invention, the diameters of the first connection port, the second drainage port, and the third drainage port are all 55 mm. The inner diameter of the drainage pipe 4 is 51 mm, and the wall thickness is 2 mm.

[0054] The multi-channel layout of this invention enables multi-directional distribution of cold air (such as left and right side walls + bottom vertical downward), covering high-temperature risk areas at different heights within the electrical cabinet (such as high-voltage wires usually distributed on the side walls, and the control module located at the bottom), and specifically solves the problem of local heat and cold convergence; the design of three pipelines balances the distribution of cold energy in each area, avoiding uneven pressure or local overcooling caused by excessive flow in a single pipeline.

[0055] To prevent condensation from forming on the outside of the drainage pipe 4 during airflow, a heat insulation layer is wrapped around its outer wall. Specifically, the heat insulation layer is made of nitrile foam. Wrapping the drainage pipe 4 with nitrile foam achieves thermal insulation and prevents condensation from adhering. Furthermore, in this embodiment, the thickness of the heat insulation layer is 20mm. Nitrile foam has low heat transfer efficiency, which can achieve thermal insulation and prevent the low-temperature cold air pipe from coming into contact with the high-temperature power wire, thus preventing condensation from adhering to the pipe.

[0056] The insulation layer of this invention uses a low thermal conductivity material (nitrile sponge has an extremely low thermal conductivity) to block heat exchange between the outer wall of the pipeline and the surrounding high-temperature environment (such as the surface of a high-voltage power line), preventing water droplets from condensing on the surface of the cold air pipeline due to temperature differences; the softness of the nitrile sponge also has a buffering and protective function, reducing the risk of damage to the pipeline from external impacts.

[0057] To secure and protect the drainage pipe 4, a modular positioning component is included. The drainage pipe 4 is positioned on the inner wall of the equipment using this component, which primarily serves to position and secure the air outlet duct. This component can be customized according to the size of the electrical cabinet. The drainage pipe 4 is secured to the modular sheet metal positioning plate 5 and the sheet metal protective cover 6, ensuring stable installation and easy maintenance.

[0058] Furthermore, the positioning assembly includes a positioning plate 5 and a protective cover 6; wherein: The positioning plate 5 is U-shaped or trapezoidal and is used to position the drainage pipe 4 on the top of the equipment. Specifically, the positioning plate 5 includes a first positioning plate 51 and a second positioning plate 52. The first positioning plate 51 is used to fix the first drainage pipe 41 on the top of the electrical control box; the second positioning plate 52 is used to fix the second drainage pipe 42 on the top of the electrical control box.

[0059] The protective cover 6 is used to cover the drainage pipe 4 on the side wall of the equipment. Specifically, the protective cover 6 includes a first protective cover 616, a second protective cover 63, and a third protective cover 62. The first protective cover 616 is used to cover the first drainage pipe 41 on the left side wall of the electrical control box, the second protective cover 63 is used to cover the second drainage pipe 42 on the right side wall of the electrical control box, and the third drainage pipe 43 is used to wrap around the middle of the electrical control box.

[0060] The modular design of this invention allows for flexible adjustment of the specifications of the positioning plate 5 / protective cover 6 according to the size of the electrical cabinet, without the need for a customized overall device; the positioning plate 5 ensures that the pipelines are firmly fixed at the top, preventing them from falling off due to vibration of the electrical cabinet; the protective cover 6 protects the side wall pipelines from scratches during manual maintenance, while also concealing the pipelines to improve the cleanliness of the interior of the electrical cabinet and indirectly extend the service life of the device.

[0061] Example 2 like Figures 1-10 As shown, the present invention provides an electrical cabinet, including an electrical cabinet box 2 with internal electronic components, an electrical cabinet air conditioner 1 installed on top of the electrical control box, and the anti-condensation device in Embodiment 1; wherein: The top of the electrical cabinet box 2 has a through opening; The air outlet 11 of the air conditioner in the electrical cabinet is directly opposite the through opening; The air manifold 3 is installed at the through-hole, that is, at the lower end of the air outlet 11 of the air conditioner 1 in the electrical cabinet, and mainly serves to combine air and prevent refrigerant leakage. The end of the drainage pipe 4 extends to the lower part of the electrical cabinet box 2, and the cold air is delivered to the lower part of the electrical cabinet through the three drainage pipes 4.

[0062] The through-hole design of this invention enables unobstructed transmission of air conditioning cold air from the top air outlet 11 to the air collection component 3; the layout of three pipes extending vertically along the left and right side walls and the middle covers the main high-temperature areas in the electrical cabinet (side wall power cables, bottom control module), and extends the cold air delivery path to the low-temperature area, avoiding direct contact with high-temperature surfaces; the symmetrical left and right + vertical middle distribution takes into account both space utilization and airflow uniformity.

[0063] In this embodiment, the first drain pipe 41 and the second drain pipe 42 are distributed along the inner sheet metal panel of the electrical cabinet, and after bending at the inner corner, they extend downward to a distance of 80mm from the bottom. The third drain pipe 43 extends vertically downward to the same distance.

[0064] In this embodiment, there are three drainage pipes 4. Two of them extend along the left and right side walls of the electrical cabinet 2, and the third extends vertically downward along the middle of the electrical cabinet 2. The drainage pipes 4 are distributed along the inner sheet metal panel of the electrical cabinet and extend downward to the bottom area of ​​the electrical cabinet, so as to achieve reasonable distribution of cold air. The three drainage pipes 4 of this invention effectively utilize the non-working area inside the electrical cabinet and change the air conditioner outlet position without interfering with the circuit axis and the installation of electrical components.

[0065] This invention addresses the condensation problem at the air outlet 11 of an electrical cabinet air conditioner 1 caused by the convergence of hot and cold air. Through the synergistic effect of an innovative airflow guiding structure design, heat insulation protection measures, and an intelligent temperature control system, it fundamentally solves the potential condensation problem caused by the contact between the low-temperature cold air at the air outlet 11 and the surface of the high-temperature power wires / components inside the electrical cabinet when the traditional electrical cabinet air conditioner 1 is installed on the top. At the same time, it optimizes the uniformity of temperature distribution inside the electrical cabinet, improving the reliability and stability of the electrical equipment operation.

[0066] Example 3 In this embodiment, the present invention provides a control method for temperature control of the electrical cabinet in Embodiment 2. In this embodiment, an intelligent temperature control system is installed in the electrical cabinet. The intelligent temperature control system includes a temperature and humidity sensor, a controller, and an air conditioning adjustment module for dynamically adjusting the outlet air temperature. Furthermore, multiple temperature and humidity sensors are installed in key areas inside the electrical cabinet (such as the area with high-voltage power lines at the top of the cabinet, the area with electrical components in the middle, and near the air outlet 11) to collect temperature and humidity data in each area in real time.

[0067] This invention introduces an intelligent temperature control system that uses temperature and humidity sensors to monitor the temperature and humidity inside the electrical cabinet in real time and automatically adjusts the air conditioner's outlet temperature to further reduce the risk of condensation.

[0068] Specifically, the control method includes the following steps: Temperature acquisition: Real-time temperature and humidity data of key areas inside the electrical cabinet box 2 are collected using several temperature and humidity sensors; Data processing and analysis: The controller receives temperature and humidity data from the temperature and humidity sensor, compares it with the preset control temperature reference group, and makes a status judgment; the control temperature reference group includes dew point temperature threshold, air outlet 11 temperature difference set value, and relative humidity. Dynamically adjust the air conditioner's outlet air temperature: Based on the status judgment result, the controller sends a command to the air conditioner's air conditioning adjustment module to adjust the air conditioner's outlet air temperature; It also includes alarm and feedback mechanisms: when the controller detects abnormal temperature or system failure, it will issue an alarm to the operator through an audible and visual alarm or a remote communication module, and record the abnormal data for subsequent analysis.

[0069] As a further improvement of the present invention, the controller receives temperature and humidity data acquired by the temperature and humidity sensor, compares it with a preset control temperature reference group, and performs a status judgment, including: When the temperature in a certain area inside the electrical cabinet 2 is lower than the dew point temperature threshold and the relative humidity is high, the controller determines that there is a risk of condensation in that area; in this embodiment, the dew point temperature threshold can be 22°C.

[0070] When the temperature difference between a certain area inside the electrical cabinet 2 and the temperature at the air outlet 11 exceeds the set temperature difference value of the air outlet 11, the controller determines that there is a risk of hot and cold air mixing. In this embodiment, the set temperature difference value at the air outlet 11 can be 8°C.

[0071] As a further improvement of the present invention, the controller sends a command to the air conditioning adjustment module of the air conditioner according to the judgment result to adjust the air conditioner outlet temperature, including: If it is determined that there is a risk of condensation, the air conditioner outlet temperature is increased, for example, from 15°C to 18°C, in order to reduce the temperature difference between hot and cold and reduce the possibility of condensation. If it is determined that there is a risk of heat and cold converging, the air conditioner outlet temperature will be lowered to improve cooling efficiency.

[0072] Through selection calculations and experimental verification, the cold air flow rate of the drainage pipe of this invention can meet the temperature control requirements of the electrical cabinet within 4 unit time, without losing the cold air flow and refrigeration efficiency.

[0073] This invention replaces manual experience-based adjustments with real-time monitoring and intelligent decision-making, ensuring that the internal temperature and humidity of the electrical cabinet are always within a safe range; dynamic adjustment balances anti-condensation and cooling efficiency, avoiding energy waste caused by excessive cooling; and the remote alarm function shortens fault response time and improves operation and maintenance efficiency.
