Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a ventilation and dehumidification component for an electrical control cabinet. Background Technology

[0002] Electrical control cabinets are commonly used electrical devices, made of steel, designed to protect components and ensure their proper functioning. They are frequently used in the power and electrical fields. Since a large number of electronic and electrical devices are installed inside the cabinet, its heat dissipation performance directly affects the lifespan and operational stability of these devices. After prolonged operation, the electrical components inside the control cabinet generate a significant amount of heat. When the control cabinet's heat dissipation is slow, it affects the lifespan of the electrical components. Furthermore, in seasons or environments with high humidity, the control cabinet is more likely to become damp, which also reduces its lifespan.

[0003] Chinese Patent CN 210053719 U discloses a layered mechanical and electrical control cabinet for convenient cable routing, including a cabinet body, cabinet doors, mounting brackets, and cable routing brackets. The cabinet body has symmetrically distributed cabinet doors, which are rotatably connected to the edges of the cabinet body. Function buttons are fixedly connected to the surface of the cabinet doors. The cabinet body has a mounting bracket inside, which includes longitudinal corner brackets and mounting plates. The mounting plates are stacked and equidistantly distributed inside the cabinet body, and both ends of the mounting plates are fixedly connected to the longitudinal corner brackets. A cable routing bracket is fixedly connected to the bottom of the mounting bracket. The cable routing bracket includes a base plate and cable routing clips. The surface of the base plate has two rows of mounting seats, arranged in upper and lower rows and staggered. The surface of the mounting seats has cable routing clips, and the top of the cable routing clips has hexagonal socket bolts. This utility model, by fixing the cable routing bracket inside the cabinet, facilitates cable routing after installation by operators, facilitates heat dissipation of electrical equipment, and makes it easier for maintenance personnel to inspect and maintain electrical equipment and wiring.

[0004] However, the aforementioned patent has multiple layers of cable trays inside the control cabinet, lacks effective heat dissipation measures, causes the internal space to heat up quickly, and cannot automatically dehumidify, making the components inside the cabinet easily damaged. The overall heat dissipation efficiency of the device is low, and the inability to automatically dehumidify reduces the service life of the device. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a ventilation and dehumidification component for an electrical control cabinet, comprising: a cabinet body 1 and a base 15. A cooling fan 2 is fixedly connected to the upper end of the cabinet body 1. The rotation of the cooling fan 2 can draw out the air inside the cabinet body 1 to achieve the purpose of cooling and heat dissipation. Two cabinet doors 17 are connected to the surface of the cabinet body 1. Sealing strips 16 are fixedly connected to the contact points of the two cabinet doors 17. The sealing strips 16 can effectively seal the inside of the cabinet body 1 to prevent humid air from outside the cabinet body 1 from entering the cabinet body 1 through the cabinet doors 17. A support block 14 is fixedly connected to the lower end of the cabinet body 1. The lower end of the support block 14 is fixedly connected to the base 15. At this time, the cabinet body 1 and the base 15 are supported and connected by the support block 14 and a gap is formed. The dehumidification component is installed in this gap.

[0021] The frame 11 is the main body of the dehumidification component. Several through holes 5 are opened on the surface of the frame 11. When the cooling fan 2 is started, the air outside the cabinet door 17 enters through the through holes 5. The lower end of the frame 11 is fixedly connected to the sliding plate 13. The upper end of the base 15 is provided with a sliding groove 12. The sliding groove 12 is slidably connected to the base 15, making it easy to inspect and replace the dehumidification component. A pull rod 18 is fixedly connected to one side of the frame 11. By applying force to the pull rod 18, it is easy to pull out the dehumidification component. Guide posts 9 are fixedly connected to both sides of the frame 11. A guide groove 10 is opened on one side of the support plate 4. The guide post 9 is slidably connected to the guide groove 10, which makes it more stable and accurate when pulling out the dehumidification component and avoids deviation.

[0022] Support plates 4 are fixedly connected to the four corners of the inner wall of frame 11. A support frame 6 and a desiccant pack 8 are fixedly connected to the upper end of the support plates 4. Through the limiting effect of the support plates 4 and the support frame 6, the desiccant pack 8 can be installed and fixed at a suitable height and position. The desiccant pack 8 contacts the inner wall of the support frame 6 to prevent air leakage. The outer wall of the support frame 6 is integrally formed and fixedly connected to the inner wall of frame 11. A dustproof net 7 is detachably installed at the upper end of the support frame 6. The dustproof net 7 can isolate dust and prevent it from entering the cabinet 1 and interfering with electronic components. The sides of the dustproof net 7... The frame 11 is in contact with the inner wall, and a bracket 3 is fixedly connected to the inner wall of the frame 11. The bracket 3 is located in the center, and the upper end of the bracket 3 is in contact with the desiccant pack 8, so that the midpoint of the desiccant pack 8 also has a stress point, thus preventing it from breaking at the midpoint. The horizontal height of the bracket 3 and the support plate 4 is higher than the through hole 5, so as to ensure that the air outside the cabinet 1 will pass through the desiccant pack 8 and the dustproof net 7 first. The desiccant pack 8 and the dustproof net 7 are breathable, and air can pass through them. The upper end of the dustproof net 7 and the frame 11 are in close contact with the lower end of the cabinet 1 to prevent air from being sucked in from the gaps.

[0023] In actual use, after the device is installed and checked to be correct, close the cabinet door 17 and start the cooling fan 2. At this time, under the action of the cooling fan 2, the air outside the cabinet 1 enters through the through hole 5, and then passes through the desiccant pack 8 and the dust filter 7 in sequence, so that the air is dried and dust is removed. The dried air will then enter the cabinet 1, thereby achieving ventilation, dehumidification and heat dissipation inside the cabinet 1. When it is necessary to replace the desiccant pack 8, simply apply force to the pull rod 18 to make it slide out of the base 15, and then remove the dust filter 7 and the desiccant pack 8 in sequence for replacement. The device is convenient and easy to operate and can effectively ventilate, dehumidify and dissipate heat.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
