Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a heat dissipation device for an electrical cabinet used in an industrial automatic control system. Background Technology

[0002] Electrical control cabinets, as an indispensable component of industrial automatic control systems, cleverly integrate electrical components, instruments, protective devices, and auxiliary electrical equipment through their enclosed or semi-enclosed structures, achieving the dual functions of centralized control and protection. However, these high-performance components generate a large amount of heat during operation. If this heat is not dissipated in a timely and effective manner, it will directly threaten the operational safety of the electrical control cabinet, potentially leading to serious consequences such as short circuits and shutdowns, affecting the continuous operation and overall efficiency of the production line.

[0003] Currently, most electrical control cabinet cooling solutions rely on the traditional method of air-cooled ventilation. While this method alleviates the heat dissipation problem to some extent, its inherent limitations cannot be ignored. The selection of ventilation hole size is a major challenge. If the hole diameter is too small, sufficient airflow cannot be guaranteed in high-temperature environments, significantly reducing the cooling effect. If the hole diameter is too large, although it enhances air exchange, it also introduces dust and impurities, posing a potential risk of contamination to the interior of the electrical control cabinet. Over long-term operation, dust and impurities easily accumulate in the ventilation holes, which may not only cause short-circuit faults between circuit boards and electronic component pins but also block the ventilation holes, severely hindering airflow and causing the internal temperature of the electrical control cabinet to rise continuously, resulting in a sharp decline in cooling efficiency.

[0028] Please refer to Figure 3 , Figure 4 and Figure 6 As an embodiment of the present utility model, the air inlet component 5 includes a support protective cover 501, wherein the support protective cover 501 is a "冂"-shaped structure with an open lower end, and the lower end of the support protective cover 501 is fixedly connected to the bottom plate 3; a fixing plate 502 and a dehumidification plate 503 are provided in the inner cavity of the support protective cover 501, and the dehumidification plate 503 is arranged above the fixing plate 502.

[0029] In the above-described scheme, the air intake component 5 is mainly responsible for guiding outside air into the electrical cabinet and simultaneously performing preliminary purification and treatment. The core component of the air intake component 5 is the support protective cover 501, which adopts a "U"-shaped structure design with an opening at the bottom. This structure is not only stable but also effectively protects the internal components from external impacts and damage. The lower end of the support protective cover is fixedly connected to the bottom plate 3 of the electrical cabinet, forming a stable frame that provides necessary support and protection for the internal air intake channel. Its "U"-shaped structure can effectively guide outside air into the electrical cabinet from the lower opening and flow into the internal cavity of the electrical cabinet through the internal channel, ensuring smooth and uniform airflow. The fixing plate 502 is located at the bottom of the inner cavity of the support protective cover 501, serving as a support. The mounting plate 502 serves to fix other intake fans 504; the mounting plate 502 is fixedly connected to the inner wall of the support protective cover 501 by bolts or other connection methods, ensuring the stability and reliability of the entire structure; the dehumidification plate 503 is set above the mounting plate 502 and is a key component for dehumidification in the air intake assembly 5; the dehumidification plate 503 is filled with desiccant 506 or other dehumidifying materials, which can absorb moisture in the air, thereby preventing electrical faults caused by excessive humidity inside the electrical cabinet; when outside air enters the electrical cabinet through the air intake assembly 5, the dehumidification plate 503 can effectively remove moisture from the air and keep the air inside the cabinet dry; dry air helps prevent electrical components from short-circuiting or corroding due to moisture, thereby extending the service life and reliability of the electrical cabinet.

[0030] During the heat dissipation process of the electrical cabinet, the air intake component 5 and the exhaust component 8 work together to form a complete air circulation system. Outside air enters the electrical cabinet through the air intake component 5, is heated by the electrical components, and is then discharged outside the cabinet by the exhaust component 8. The dehumidification plate 503 in the air intake component 5 can also perform preliminary purification treatment on the incoming air, reducing the pollution and damage of dust and impurities to the electrical components, and providing strong support for the heat dissipation of the electrical cabinet and the protection of the electrical components.

[0031] Please see Figure 6 As one embodiment of the present utility model, the two side walls of the fixing plate 502 are fixedly connected to the inner wall of the support protective cover 501, wherein the upper end of the fixing plate 502 is equipped with an air inlet fan 504, and the air inlet fan 504 corresponds to the air inlet hole 4.

[0032] In the above-described scheme, the main function of the fixing plate 502 is to provide a stable mounting platform for the intake fan 504. The fixing plate 502 is fixedly connected to the inner wall of the support protective cover 501 through its two side walls, ensuring the stability and reliability of the intake fan 504 during operation. The design of the fixing plate 502 also takes into account the airflow guiding effect. Its shape and position allow outside air to smoothly enter the inner cavity of the support protective cover 501 through the air inlet 4, and flow towards the intake fan 504 under the guidance of the fixing plate 502. The intake fan 504 uses the suction force generated by its rotation to draw outside air... The air is drawn into the inner cavity of the support cover 501 and enters the electrical cabinet through the air inlet 4. The intake fan 504 usually has the function of adjusting the air volume. According to the temperature change and heat dissipation requirements inside the electrical cabinet, the amount of air drawn in can be changed by adjusting the speed of the intake fan 504, thereby achieving precise control of the heat dissipation process. The operation of the intake fan 504 not only promotes the entry of outside air into the electrical cabinet, but also promotes the circulation of air inside the cabinet. Through the synergy with the exhaust assembly 8, a complete air circulation system is formed, ensuring the continuous renewal of air inside the electrical cabinet and improving the heat dissipation effect.

[0033] Please see Figure 6 As one embodiment of the present utility model, the two long sides of the dehumidification plate 503 are slidably connected to the inner wall of the support protective cover 501, wherein the dehumidification plate 503 is provided with a dehumidification groove 505; the bottom of the dehumidification groove 505 is connected to the inlet fan 504, wherein a desiccant 506 is provided in the dehumidification groove 505.

[0034] In the above-described scheme, the two long sides of the dehumidifying plate 503 are slidably connected to the inner wall of the supporting protective cover 501. This design allows the dehumidifying plate 503 to be easily installed and disassembled, facilitating the replacement of the internal desiccant 506. The sliding connection also ensures the stability of the dehumidifying plate 503 during operation, preventing displacement or loosening caused by vibration or airflow impact. A dehumidifying groove 505 is provided on the dehumidifying plate 503, which is a space specifically for accommodating the desiccant 506. The design of the dehumidifying groove 505 takes into account the airflow path and the desiccant 506. The contact area with air is maximized to ensure optimal dehumidification. The shape and size of the dehumidification tank 505 are typically customized according to the size of the electrical cabinet and heat dissipation requirements to meet the needs of different application scenarios. An air duct connected to the intake fan 504 is opened at the lower end of the dehumidification tank 505, which ensures that when outside air is drawn into the inner cavity of the support cover 501 by the intake fan 504, it can flow through the dehumidification tank 505 and fully contact the desiccant 506. The design of the air duct also considers the uniformity and speed of airflow to ensure that the desiccant 506 can fully exert its dehumidification effect.

[0035] The main function of desiccant 506 is to absorb moisture from the air. When outside air enters the dehumidification tank 505 through the through-hole 12, desiccant 506 absorbs the moisture, thereby reducing the humidity of the air. The selection of desiccant 506 is usually based on its moisture absorption performance, stability, and service life. Common desiccants 506 include silica gel and calcium chloride. After absorbing a certain amount of moisture, the dehumidification capacity of desiccant 506 will gradually decrease. To maintain the dehumidification effect, desiccant 506 needs to be regenerated or replaced regularly.

[0036] Please refer to the accompanying diagram. Figure 1 , Figure 3 and Figure 6 As an embodiment of this utility model, the upper end of the support protective cover 501 is evenly provided with a plurality of ventilation holes 507, wherein one end of the support protective cover 501 is provided with a movable hole 10; a through hole 12 is provided on the left side plate 11 of the cabinet 1 near the movable hole 10, wherein the dehumidifying plate 503 extends outward into the through hole 12 at the end near the movable hole 10, and a sealing block 13 adapted to the through hole 12 is provided on the dehumidifying plate 503.

[0037] In the above-described scheme, a number of ventilation holes 507 are evenly distributed on the upper end of the support protective cover 501. The main function of these ventilation holes 507 is to allow outside air to smoothly enter the electrical cabinet after dehumidification. The number and size of the ventilation holes 507 are usually customized according to the heat dissipation requirements and spatial layout of the electrical cabinet to ensure optimal air circulation and heat dissipation performance. As the external frame of the entire air intake assembly 5, the support protective cover 501 not only provides a platform for installing and fixing internal components, but also protects the internal components from external impacts and damage. Through its robust structure and reasonable layout, the support protective cover 501 ensures the stability and reliability of the air intake assembly 5 during operation.

[0038] One end of the protective cover 501 is provided with a movable hole 10, which is used to facilitate the installation, disassembly, and replacement of the dehumidification plate 503. The design of the movable hole 10 takes into account the size and shape of the dehumidification plate 503, as well as the convenience and safety during operation. A through hole 12 is opened on the left side panel 11 of the cabinet 1 near the movable hole 10. This through hole 12 is adapted to the end of the dehumidification plate 503 near the movable hole 10, allowing the dehumidification plate 503 to extend outward into the through hole 12 when needed. The design of the through hole 12 also takes into account sealing and dust prevention, ensuring that the sealing performance and dust prevention effect of the electrical cabinet are not affected when the dehumidification plate 503 extends or retracts. The design of the dehumidification plate 503 extending outward into the through hole 12 near the movable hole 10 allows... When replacing the desiccant 506 or performing other maintenance operations, the dehumidifying plate 503 can be easily pulled out or pushed in through the through hole 12. The extension portion is usually adapted to the shape and size of the through hole 12 to ensure that the dehumidifying plate 503 can move smoothly when extended or retracted. The dehumidifying plate 503 is provided with a sealing block 13 adapted to the through hole 12. The main function of this sealing block 13 is to prevent outside air or dust from entering the electrical cabinet through the through hole 12 when the dehumidifying plate 503 is extended or retracted. The sealing block 13 is usually made of elastic material to ensure a good sealing effect between the dehumidifying plate 503 and the through hole 12. At the same time, the design of the sealing block 13 also takes into account wear resistance and corrosion resistance to ensure its long-term reliability and stability.

[0039] Please refer to the accompanying diagram. Figure 4 and Figure 7a , 7b As an embodiment of the present utility model, the exhaust assembly 8 includes a housing 801, wherein the outer wall of the housing 801 is fixedly connected to the exhaust hole 7; one end of the housing 801 is provided with an air inlet, wherein the air inlet is located in the inner cavity of the cabinet 1; the other end of the housing 801 is provided with an exhaust port, wherein the exhaust port is located on the outer side of the cabinet 1; heat exchange fins 802 are provided on the side of the housing 801 near the air inlet, wherein an exhaust fan 803 is provided on the side of the housing 801 near the exhaust port; a protective plate 804 is provided at the air inlet of the housing 801, wherein a plurality of filter holes 805 are evenly distributed on the protective plate 804.

[0040] In the above-described scheme, the housing 801 is the main structure of the exhaust assembly 8. Its outer wall is fixedly connected to the exhaust port 7, forming a closed channel for exhausting hot air from the cabinet 1. The design of the housing 801 takes into account strength and sealing to ensure that no leakage occurs during exhaust, thus affecting the heat dissipation effect. The air inlet is located inside the cabinet 1 and is the entrance for hot air to enter the housing 801. The design of the air inlet takes into account the smoothness and uniformity of airflow to ensure that the hot air inside the cabinet 1 can fully enter the housing 801 and dissipate heat through the heat exchange fins 802. The exhaust port is located outside the cabinet 1 and is the outlet for hot air to exit the housing 801. The design of the exhaust port takes into account the speed and direction of airflow to ensure that the hot air... Air can be smoothly discharged outside the cabinet 1, avoiding the formation of eddies or dead corners inside the cabinet 1; heat exchange fins 802 are located on the side of the shell 801 near the air inlet, their function is to increase the contact area between the air and the wall of the shell 801, thereby improving heat dissipation efficiency; heat exchange fins 802 are usually made of materials with good thermal conductivity, such as aluminum alloy, to ensure that heat can be quickly transferred to the shell 801 and discharged through the exhaust port; exhaust fan 803 is located on the side of the shell 801 near the exhaust port, its function is to generate negative pressure, draw hot air from the cabinet 1 into the shell 801, and discharge it through the exhaust port; the speed and power of exhaust fan 803 are usually customized according to the heat dissipation requirements and space layout of the electrical cabinet to ensure optimal exhaust effect and heat dissipation performance.

[0041] The protective plate 804 is installed at the air inlet of the housing 801. Its function is to prevent dust from the inner cavity of the cabinet 1 from entering the inner cavity of the housing 801, affecting the heat dissipation effect and the normal operation of the exhaust fan 803. The design of the protective plate 804 takes into account strength and filtration performance to ensure that air circulation is not affected while protecting the exhaust fan 803. The filter holes 805 are evenly distributed on the protective plate 804 and serve as the channel for air to enter the housing 801. The number and size of the filter holes 805 are usually customized according to the power and heat dissipation requirements of the exhaust fan 803 to ensure optimal air circulation and heat dissipation performance.

[0042] The various parts of the exhaust assembly 8 work together to form a complete heat dissipation system. Hot air from inside the cabinet 1 is drawn into the housing 801 through the air inlet. After being cooled by the heat exchange fins 802, the hot air is then exhausted to the outside of the cabinet 1 by the negative pressure of the exhaust fan 803. This achieves effective exhaust and heat dissipation of hot air inside the electrical cabinet, providing strong support for the normal operation of the electrical cabinet.
