Description

Technical Field

[0001] This utility model relates to the field of switch cabinet manufacturing, and in particular to a switch cabinet with high ventilation. Background Technology

[0002] Traditional switchgear relies heavily on fans at the bottom, sides, or top of the cabinet for heat dissipation, which only disturbs the internal airflow and has limited cooling effect. Because hot air rises, some cabinets have fans at the bottom, but the switch groups above lack adequate structural space, resulting in most airflow being blocked by the bottom switch groups. This leads to poor airflow and inadequate heat dissipation. Furthermore, insufficient space between the fan and the bottom of the cabinet results in poor air intake; and the fan's location at the bottom makes repair and replacement difficult after damage, further affecting the long-term heat dissipation stability of the switchgear and making it difficult to meet the continuous cooling needs of the densely packed switch groups inside. Utility Model Content

[0003] The purpose of this invention is to provide a highly ventilated switch cabinet with good heat dissipation performance.

[0004] The purpose of this utility model is achieved as follows: A highly ventilated switch cabinet includes a cuboid frame and a cooling fan assembly placed at the bottom of the cuboid frame. The cuboid frame has symmetrically arranged movable supports on its sides. A front mounting bracket and a rear mounting bracket are arranged between the symmetrical movable supports, with the front and rear mounting brackets arranged in an alternating pattern. Switch assemblies are mounted on the front and rear mounting brackets. A gap is left between the switch assembly on the rear mounting bracket and the vertical plane where the front mounting bracket is located, forming a ventilation channel. The cooling fan assembly is placed directly below the ventilation channel. The cooling fan assembly is placed on a sliding bracket. The top of the cuboid frame has an air outlet structure, and the bottom has an air inlet structure.

[0005] Preferably, a fixed bracket is provided on the lower side of the cuboid frame, and two sets of vertical brackets are provided between the fixed bracket and the bottom of the cuboid frame. A track is provided between the vertical brackets located symmetrically on the side of the cuboid frame.

[0006] Preferably, a limiting groove is provided on the opposite side of the track, the sliding bracket is placed in the limiting groove, and a rubber layer is provided in the limiting groove.

[0007] Preferably, the side plate of the cuboid frame is provided with a movable door corresponding to the track.

[0008] Preferably, both the air outlet structure and the air inlet structure have multiple sets of ventilation holes on the side plate.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. The front and rear mounting brackets are arranged alternately. The switch group on the rear mounting bracket and the vertical plane of the front mounting bracket form a ventilation channel. The cooling fan group is placed directly below the channel. Together with the top air outlet structure and the bottom air inlet structure, a smooth airflow path of "bottom in and top out" is formed, which avoids the airflow being blocked by the switch group, greatly improves the efficiency of hot air exhaust, and meets the heat dissipation needs of dense switch groups.

[0011] 2. The cooling fan assembly is placed on a sliding bracket. The sliding bracket is adapted to the limiting groove of the track, and the side of the cabinet is equipped with a corresponding movable door. By opening the movable door, the sliding bracket can be pulled out and the fan assembly can be quickly taken out for maintenance or replacement.

[0012] 3. The bottom of the cabinet is raised to allow for 5-10cm of air intake space, which improves the air intake effect; the rubber layer in the track limiting groove can limit the sliding bracket and reduce the noise of the fan. At the same time, a second track and fan group can be added as needed to flexibly improve the ventilation performance and balance ventilation efficiency and operational stability.

[0015] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0016] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] like Figure 1 As shown, a highly ventilated switch cabinet includes a rectangular frame 1 and a cooling fan assembly 2 placed at the bottom of the rectangular frame 1. The rectangular frame 1 has symmetrically arranged movable supports 3 on its sides. A front mounting bracket 4 and a rear mounting bracket 5 are arranged between the symmetrical movable supports 3, with the front and rear mounting brackets 4 and 5 arranged in an alternating pattern. Switch assemblies 6 are mounted on the front and rear mounting brackets 4. A gap is left between the switch assembly on the rear mounting bracket 5 and the vertical plane of the front mounting bracket 4, forming a ventilation channel 7. The cooling fan assembly 2 is placed directly below the ventilation channel 7 and is mounted on a sliding bracket 10. The top of the rectangular frame 1 has an air outlet structure 8, and the bottom has an air inlet structure 9. In the design, the bottom of the rectangular frame needs to be heightened, with an additional 5-10 cm reserved for air intake compared to traditional cabinets.

[0019] A fixed bracket 11 is provided on the lower side of the cuboid frame 1. Two sets of vertical brackets 12 are provided between the fixed bracket 11 and the bottom of the cuboid frame 1. A track 13 is provided between the vertical brackets 12 that are symmetrical on the side of the cuboid frame 1. When greater ventilation performance is required, a second track and a cooling fan group can be set in the cabinet area inward of the track to improve the ventilation performance of the back of the rear installation.

[0020] A limiting groove 1301 is provided on the opposite side of the track 13. The sliding bracket 10 is placed in the limiting groove 1301. A rubber layer is provided in the limiting groove 1301. The rubber layer can effectively limit the sliding bracket and reduce noise.

[0021] The side panel of the cuboid frame 1 is equipped with a movable door corresponding to the track. Opening the movable door allows the internal fan assembly to be removed for maintenance and replacement, which is convenient and quick.

[0022] Both the air outlet structure 8 and the air inlet structure 9 have multiple sets of ventilation holes on the side panel. Air enters from the air inlet structure, and hot air is discharged from the air outlet structure above. The hot air has a low relative density and is discharged upward more quickly.

[0023] The working principle of this invention is explained as follows: During operation, external air enters through the air intake structure at the bottom of the cabinet, activating the cooling fan assembly and directing the airflow upwards to the ventilation channel. Because the ventilation channel formed by the staggered arrangement of the front and rear mounting brackets is unobstructed by the switch assembly, the airflow can flow smoothly upwards, carrying away the heat generated by the switch assembly, forming a complete "bottom in, top out" heat dissipation cycle. When fan maintenance is required, simply open the side door and pull out the sliding bracket carrying the fan assembly along the track. To enhance ventilation, additional tracks and fan assemblies can be added inside the track to further improve heat dissipation capacity.

[0024] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
