Description

Technical Field

[0001] This application relates to the technical field of control cabinets, and particularly to a control cabinet with high moisture-proof performance. Background Art

[0002] The origin of the control cabinet can be traced back to the era when the demand for industrial production and electronic equipment protection was growing continuously. With the progress of technology and the improvement of industrial automation, various precision electronic devices, control systems, and power equipment have been widely used in all walks of life. These devices often need to operate under specific environmental conditions to ensure their stability and reliability. Therefore, the control cabinet emerged as an important equipment protection and management tool.

[0003] With the rapid development of modern industry and electronic technology, various precision electronic devices, control systems, and data storage devices have been widely used in all walks of life. However, these devices often have extremely high requirements for the operating environment, especially in terms of humidity control. A high-humidity environment not only causes corrosion and accelerated aging of the internal components of the device, but may also lead to safety hazards such as short circuits and electric leakage, seriously affecting the stability and service life of the device. Therefore, this patent needs to be upgraded and improved on the basis of the existing technology. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, this application provides a control cabinet with high moisture-proof performance, which overcomes the deficiencies of the existing technology and aims to solve the problems that the internal equipment of the control cabinet in a high-humidity environment not only causes corrosion and accelerated aging of the internal components of the device, but may also lead to safety hazards such as short circuits and electric leakage, seriously affecting the stability and service life of the device.

[0005] To achieve the above object, this application provides the following technical solution: A control cabinet with high moisture-proof performance, including a cabinet body. Moisture isolation plates are provided on both sides of the cabinet body. An evaporation sheet is fixedly connected inside the moisture isolation plate. An evaporation pipe penetrates through the inside of the moisture isolation plate. One end of the evaporation pipe on one side is connected to a connection pipe. A cabinet top is fixedly connected to the top of the cabinet body. A condensation sheet is fixedly connected to the bottom inside the cabinet top. A condensation pipe penetrates through the inside of the condensation sheet. One end of the condensation pipe is fixedly connected to a throttling component. The throttling component is fixedly connected to the corner position at the top of the cabinet body. The bottom end of the throttling component is fixedly connected to the connection pipe. A protective cover is fixedly connected to the top of the cabinet top. A motor is fixedly connected to the inner top of the protective cover. A heat dissipation fan is fixedly connected to the driving end of the motor.

[0006] By adopting the above technical solution, the motor is turned on during daily use. At this time, the motor drives the cooling fan to rotate. During the rotation of the cooling fan, the air flow inside the control cabinet will be accelerated, enabling the air inside the control to quickly pass through the protective cover and be discharged outside. At the same time, new air will quickly enter the control cabinet through the moisture isolation plate, thereby reducing the temperature inside the control. When the external air humidity is high during the plum rain season, the control cabinet can condense the air entering the control cabinet through the evaporation tube to generate liquid water droplets and attach them to the outside of the evaporation sheet. Then, the liquid water droplets will slide down along the evaporation tube until they are discharged outside the control cabinet. At this time, the air entering the control cabinet no longer contains a large amount of moisture, thus preventing the equipment inside the control cabinet from being damaged due to moisture.

[0007] As a preferred technical solution of the present application, a lower cabinet is fixedly connected to the bottom of the cabinet body. One end of the bottom of the evaporation tube is fixedly connected to a connecting pipe. The connecting pipe extends along the side of the cabinet body into the lower cabinet. The connecting pipe extends along the inside of the lower cabinet to the other side position of the cabinet body. The connecting pipe penetrates through the top of the lower cabinet along the other side of the cabinet body and is connected to the bottom of the evaporation tube on the other side. One end of the top of the evaporation tube on the other side is fixedly connected to a discharge pipe. The discharge pipe penetrates through the top of the lower cabinet and is fixedly connected to a compressor at the end. The other end of the condensation tube is fixedly connected to a guiding pipe. The guiding pipe extends downward along the side of the cabinet body into the compressor. The compressor is fixedly connected inside the lower cabinet.

[0008] By adopting the above technical solution, the compressor compresses the gas to form a high-pressure and high-temperature gas, and then enters the condensation tube through the guiding pipe. The condensation tube releases heat through the condensation fins to cool the gas. After cooling, the high-pressure and high-temperature gas becomes a medium-temperature and high-pressure liquid, and then enters the throttling component. The throttling component throttles and depressurizes the low-temperature and low-pressure gas-liquid mixture, and then enters the evaporation tube through the connecting pipe. At this time, the evaporation tube absorbs the heat in the air and vaporizes into a gas state, and then returns to the compressor through the discharge pipe to continue compression, and continues to circulate for refrigeration.

[0009] As a preferred technical solution of the present application, air intake holes are provided on both sides of the cabinet body, and the two air intake holes are respectively opposite to the outside of the moisture isolation plate.

[0010] By adopting the above technical solution, external air can enter the control through the air intake holes, thereby cooling the inside of the control cabinet.

[0011] As a preferred technical solution of the present application, a diversion plate is fixedly connected to the bottom of the evaporation sheet. One end of the diversion plate is inclined downward. Drainage holes are provided on both sides of the cabinet body at the lower side position of the air intake holes, and the drainage holes are correspondingly arranged at the bottom of one end of the diversion plate.

[0012] By adopting the above technical solution, after the evaporation sheet condenses and adsorbs the moisture in the air, the water droplets slide downward under the influence of gravity until they enter the top of the diversion plate. Since one end of the diversion plate is inclined downward, the water droplets continue to slide downward until they enter the drainage hole and are discharged.

[0013] As a preferred technical solution of the present application, a connecting strip is fixedly connected inside the cabinet body. Four connecting strips are provided and are respectively fixedly connected to both sides of the moisture isolation plate. A support plate is arranged inside the cabinet body, and both sides of the support plate are fixedly connected to the side of the connecting strip through bolts.

[0014] By adopting the above technical solution, the control devices can be sequentially placed on the top of the support plate, thereby realizing the stable storage of the devices. The front and rear sides of the cabinet body are rotatably connected with cabinet doors, and the control cabinet is closed through the cabinet doors.

[0015] As a preferred technical solution of the present application, a heat dissipation net is provided on the top of the cabinet top, and mounting holes are provided on the outer side of the moisture isolation plate.

[0016] By adopting the above technical solution, four mounting holes are provided and are symmetrically arranged on both sides of the moisture isolation plate respectively. The moisture isolation plate is fixed inside the cabinet body through the arrangement of the mounting holes. Through the heat dissipation net, sundries can be prevented from falling into the top of the cabinet top and affecting the operation of the heat dissipation fan.

[0017] Advantages of the present application:

[0018] In the present utility model, the control cabinet realizes the efficient dehumidification of the internal environment through the integrated refrigeration and dehumidification system. The coordinated operation of key components such as the compressor, condenser sheet, and evaporation sheet forms a closed-loop refrigeration and dehumidification cycle, which can quickly condense the moisture in the air into water droplets and discharge them outside the cabinet. This efficient dehumidification mechanism ensures that the inside of the control cabinet always maintains a low humidity state, effectively preventing problems such as equipment damage, corrosion, or short circuit caused by moisture.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0032] Refer to Figures 1-11, A control cabinet with high moisture resistance, including a cabinet body 1. Moisture isolation plates 7 are provided on both sides of the cabinet body 1. An evaporation sheet 701 is fixedly connected inside the moisture isolation plate 7. A plurality of evaporation sheets 701 are fixedly connected inside the moisture isolation plate 7 in an equidistant arrangement order. An evaporation pipe 702 is connected through the inside of the moisture isolation plate 7. One end of the evaporation pipe 702 on one side is connected to a connecting pipe 704. A cabinet top 4 is fixedly connected to the top of the cabinet body 1. A condensation sheet 403 is fixedly connected to the bottom inside the cabinet top 4. A plurality of groups of condensation sheets 403 are fixedly connected to the bottom of the cabinet top 4 in an equidistant arrangement order. A condensation pipe 404 is connected through the inside of the condensation sheet 403. One end of the condensation pipe 404 is fixedly connected to a throttling component 14. The throttling component 14 is fixedly connected to the corner position at the top of the cabinet body 1. The bottom end of the throttling component 14 is fixedly connected to the connecting pipe 704. A protective cover 401 is fixedly connected to the top of the cabinet top 4. A motor 405 is fixedly connected to the inner top position of the protective cover 401. The driving end of the motor 405 is fixedly connected to a cooling fan 406. When in daily use, the motor 405 is turned on. At this time, the motor 405 drives the cooling fan 406 to rotate. During the rotation of the cooling fan 406, the air flow inside the control cabinet will be accelerated, so that the air inside the control quickly passes through the protective cover 401 and is discharged to the outside. At the same time, new air will quickly enter the control cabinet through the moisture isolation plate 7, thereby reducing the internal temperature of the control. When the external air humidity is high during the plum rain season, the control cabinet can condense the air entering the control cabinet through the evaporation pipe 702 to generate liquid water droplets and attach them to the outside of the evaporation sheet 701. Then the liquid water droplets will slide down along the evaporation pipe 702 until they are discharged outside the control cabinet. At this time, the air entering the control cabinet no longer contains a large amount of moisture, thus preventing the equipment inside the control cabinet from being damaged due to moisture.

[0033] In this embodiment, as Figure 1 - Figure 11As shown in the figure, a lower cabinet 2 is fixedly connected to the bottom of the cabinet body 1. One side of the bottom of the evaporation pipe 702 is fixedly connected to a connecting pipe 8. The connecting pipe 8 extends along the side of the cabinet body 1 to the inside of the lower cabinet 2. The connecting pipe 8 extends along the inside of the lower cabinet 2 to the other side position of the cabinet body 1. The connecting pipe 8 penetrates through the top of the lower cabinet 2 along the other side of the cabinet body 1 and is connected to the bottom of the evaporation pipe 702 on the other side. One end of the top of the evaporation pipe 702 on the other side is fixedly connected to a discharge pipe 9. The discharge pipe 9 penetrates through the top of the lower cabinet 2 and the end is fixedly connected to a compressor 11. The other end of the condenser pipe 404 is fixedly connected to a guiding pipe 10. The guiding pipe 10 extends downward along the side of the cabinet body 1 into the compressor 11. The compressor 11 is fixedly connected inside the lower cabinet 2. The gas is compressed by the compressor 11 to form a high-pressure and high-temperature gas, and then enters the condenser pipe 404 through the guiding pipe 10. The condenser pipe 404 releases heat through the condenser fins 403 to cool the gas. After cooling, the high-pressure and high-temperature gas becomes a medium-temperature and high-pressure liquid, and then enters the throttling component 14. The throttling component 14 throttles and reduces the pressure to form a low-temperature and low-pressure gas-liquid mixture, and then enters the evaporation pipe 702 through the connecting pipe 704. At this time, the evaporation pipe 702 absorbs the heat in the air and vaporizes into a gas state, and then returns to the compressor 11 through the discharge pipe 9 to continue compression, and the refrigeration cycle continues.

[0034] In this embodiment, as Figure 1 - Figure 11 shown, air inlet holes 12 are provided on both sides of the cabinet body 1. The two air inlet holes 12 are respectively opposite to the outside of the moisture isolation plate 7. External air can enter the control interior through the air inlet holes 12, thereby cooling the interior of the control cabinet.

[0035] In this embodiment, as Figure 1 - Figure 11 shown, a flow guide plate 705 is fixedly connected to the bottom of the evaporation fin 701. One end of the flow guide plate 705 is inclined downward. Drainage holes 13 are provided on both sides of the cabinet body 1 at the lower side position of the air inlet holes 12. The drainage holes 13 are correspondingly arranged at the bottom of one end of the flow guide plate 705. After the evaporation fin 701 condenses and adsorbs the moisture in the air, the water droplets slide downward under the influence of gravity until they enter the top of the flow guide plate 705. Since one end of the flow guide plate 705 is inclined downward, the water droplets continue to slide downward until they enter the drainage holes 13 and are discharged.

[0036] In this embodiment, as Figure 1 - Figure 11 shown, a connecting strip 5 is fixedly connected inside the cabinet body 1. Four connecting strips 5 are provided and are respectively fixedly connected to both sides of the moisture isolation plate 7. A support plate 6 is arranged inside the cabinet body 1. Both sides of the support plate 6 are fixedly connected to the side of the connecting strip 5 by bolts. The control equipment can be sequentially placed on the top of the support plate 6 to achieve stable storage of the equipment. The front and rear sides of the cabinet body 1 are rotatably connected with cabinet doors 3, and the control cabinet is closed through the cabinet doors 3.

[0037] In this embodiment, as Figure 1 - Figure 11 shown, a heat dissipation net 402 is provided at the top of the cabinet top 4, and mounting holes 703 are provided on the outer side of the moisture isolation plate 7. Among them, four mounting holes 703 are symmetrically arranged on both sides of the moisture isolation plate 7. The setting of the mounting holes 703 realizes the fixation of the moisture isolation plate 7 inside the cabinet body 1. Through the heat dissipation net 402, sundries can be prevented from falling onto the top of the cabinet top 4 and affecting the operation of the heat dissipation fan 406.

[0038] Working principle: Control the start of the motor 405, the motor starts to rotate, drives the heat dissipation fan 406 to operate at high speed. The airflow generated by the heat dissipation fan enters the control cabinet through the heat dissipation net 402 on the cabinet top, forming air convection. The hot air is inhaled and discharged through the fan at an accelerated speed. At the same time, the external fresh air enters the control cabinet through the air inlet hole 12. With the discharge of the hot air and the entry of the fresh air, the temperature inside the control cabinet is thus reduced;

[0039] When the humidity or temperature inside the control cabinet is too high, the compressor 11 inhales the low-temperature and low-pressure gaseous refrigerant, compresses it into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the area of the condenser fins 403 through the condenser tube 404, exchanges heat with the surrounding air, releases heat and condenses into a liquid refrigerant. The liquid refrigerant is throttled and depressurized by the throttling component 14, becoming a low-temperature and low-pressure gas-liquid mixture. The gas-liquid mixture enters the evaporation tube 702, absorbs the heat in the air on the evaporation fins 701 and vaporizes, becoming a gas. At this time, the moisture in the air is condensed and adheres to the evaporation fins, forming water droplets. The water droplets slide down along the evaporation tube and the guide plate 705, and finally are discharged outside the control cabinet through the drain hole 13. The vaporized refrigerant returns to the compressor through the discharge pipe 9 to continue the next round of compression, condensation, throttling and evaporation processes, forming a continuous refrigeration and dehumidification cycle.

[0040] The above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
