Description

Technical Field

[0001] This application relates to the field of electrical equipment enclosure technology, and in particular to a transparent, visible sealed structure with a metal shielding mesh. Background Technology

[0002] In modern industrial and power systems, key equipment such as electrical shielding cabinets for rail transit and high-voltage shielding cabinets for substations operate in complex environments, placing multiple requirements on the equipment enclosures. To prevent the intrusion of external environmental factors such as dust and moisture and to ensure the long-term reliable operation of internal precision electronic components, the enclosures must achieve a high level of protection and a reliable physical seal.

[0003] To meet visibility requirements, these cabinets often focus on solving technical problems related to sealing and shielding. A common solution is to use a structure with a single layer of metal mesh or perforated metal sheet sandwiched between two transparent panels. While this structure can achieve transparency, shielding, and sealing to a certain extent, the sealed cabinet itself is not conducive to natural convection heat dissipation. Furthermore, the presence of the shielding layer in the observation window area may actually hinder heat conduction and radiation, becoming a heat dissipation bottleneck.

[0004] In other words, existing technologies suffer from the following technical problem: the heat dissipation effect of ordinary electrical equipment enclosures is insufficient due to their sealed and shielded structure. Therefore, a transparent and visible sealed structure with a metal shielding mesh is proposed to address the above problem. Summary of the Invention

[0005] This application provides a transparent, visible sealed structure with a metal shielding mesh to solve the problem of insufficient heat dissipation in ordinary electrical equipment enclosures due to their sealed shielding structure.

[0006] According to one aspect of this application, a transparent, visible sealing structure with a metal shielding mesh is provided, comprising:

[0007] The frame has a metal shielding mesh fixedly installed on its inner side.

[0008] A transparent outer panel is fixedly connected to one side of the frame, and a transparent inner panel is fixedly connected to the other side of the frame.

[0009] The metal shielding mesh includes metal horizontal plates and metal vertical plates. There are several metal horizontal plates and metal vertical plates, and these metal horizontal plates and metal vertical plates are fixedly connected to each other in a grid-like cross shape.

[0010] It also includes a ventilation module for guiding airflow through the metal shielding mesh.

[0011] Furthermore, the air module includes an exhaust vent, an exhaust duct, and an exhaust fan;

[0012] The exhaust vent is located above the side wall of the transparent inner panel, and a hood is fixedly installed on the side of the exhaust vent.

[0013] Furthermore, the exhaust duct is fixedly installed at the lower side wall of the transparent outer panel;

[0014] An exhaust fan is also fixedly installed inside the exhaust duct.

[0015] Furthermore, elongated holes are provided on several of the metal horizontal plates.

[0016] Furthermore, a heat-conducting base is fixedly connected to the side wall of the transparent inner panel, and several heat-conducting connecting plates are provided on the side wall of the heat-conducting base. The several heat-conducting connecting plates are fixedly connected to each other by a metal shielding mesh.

[0017] Furthermore, both the metal shielding mesh and the heat-conducting base are made of aluminum alloy or copper alloy, which have excellent electrical and thermal conductivity.

[0018] Furthermore, the metal shielding mesh consists of a first shielding mesh and a second shielding mesh.

[0019] Furthermore, adjusting rods are fixedly connected to both the top and bottom sides of the first shielding mesh, and adjusting rods are fixedly connected to both the left and right sides of the second shielding mesh.

[0020] Furthermore, the adjusting rods connecting the first and second shielding nets both pass through the corresponding guide grooves on the side wall of the frame and slide with the frame, and the adjusting rods are threaded with locking bolts.

[0021] The present application addresses the problem that existing plate-like structures with metal mesh shielding layers, which consist of only a thin mesh and have limited functionality, cannot effectively solve the heat dissipation problem of equipment inside the cabinet while ensuring electromagnetic shielding effectiveness and equipment sealing. This is particularly problematic when the equipment has a high power density, leading to localized overheating. The present application designs a structure that seals a three-dimensional plate-like metal shielding mesh between two transparent panels. Through the combination of the three-dimensional structure of the metal shielding mesh and the ventilation module, the metal shielding mesh can simultaneously serve as a wind guide, heat dissipation fins, and electromagnetic shield, forming a composite structure integrating shielding, heat dissipation, visibility, and sealing functions. On one hand, the transparent outer and inner panels ensure visibility of the equipment's interior; on the other hand, the sandwiched metal shielding mesh provides electromagnetic shielding while also utilizing its plate-like structure for heat conduction and dissipation. This ensures reliable operation of the equipment in complex electromagnetic environments and optimizes internal heat dissipation, making it particularly suitable for sealed cabinets with high requirements for electromagnetic compatibility, protection level, and heat dissipation, such as those used in rail transit electrical shielding cabinets and substation high-voltage shielding cabinets.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] Please see Figure 1 and Figure 2 As shown, the transparent, visible sealed structure with a metal shielding mesh includes:

[0034] Frame 1, with a metal shielding mesh 4 fixedly installed on the inner side of frame 1;

[0035] A transparent outer panel 2 is fixedly connected to one side of the frame 1, and a transparent inner panel 3 is fixedly connected to the other side of the frame 1, forming a transparent cavity that completely seals the metal shielding mesh 4 inside.

[0036] The metal shielding mesh 4 includes metal horizontal plates 401 and metal vertical plates 402. Several metal horizontal plates 401 and metal vertical plates 402 are provided. Several metal horizontal plates 401 and metal vertical plates 402 are arranged in a grid-like cross shape and are fixedly connected to each other by welding or integral molding to form a three-dimensional mesh plate with a specific thickness.

[0037] It also includes a ventilation module 5, which guides airflow through the metal shielding mesh 4 to enhance heat dissipation.

[0038] This application combines the three-dimensional structure of the metal shielding mesh 4 with the ventilation module 5, allowing the metal shielding mesh 4 to simultaneously function as an air guide, heat dissipation fins, and electromagnetic shield, forming a composite structure that integrates shielding, heat dissipation, visibility, and sealing functions. On one hand, the transparent outer panel 2 and the transparent inner panel 3 ensure the visibility of the equipment's interior. On the other hand, the metal shielding mesh 4 it holds provides electromagnetic shielding and also utilizes its plate structure to conduct heat and dissipate heat. This ensures reliable operation of the equipment in complex electromagnetic environments and optimizes internal heat dissipation. It is particularly suitable for sealed cabinets such as rail transit electrical shielding cabinets and substation high-voltage shielding cabinets, which have high requirements for electromagnetic compatibility, protection level, and heat dissipation.

[0039] In a preferred embodiment of this application, see [reference] Figure 1 and Figure 3 As shown, the ventilation module 5 includes an exhaust vent 501, an exhaust duct 503, and an exhaust fan 504.

[0040] The exhaust vent 501 is located above the side wall of the transparent inner panel 3, and a hood 502 is fixedly installed on the side of the exhaust vent 501.

[0041] Specifically, in the cabinet formed by the combination of the present application, the exhaust vent 501 and the hood 502 are located inside the cabinet near the heating element or the area where hot air gathers. This is conducive to collecting and guiding the heated air that rises, so that the heated air rising inside the cabinet can be efficiently captured and discharged outside the cabinet through the exhaust vent 501, forming an effective hot air outlet channel.

[0042] Further, see Figure 1 and Figure 2 As shown, the exhaust pipe 503 is fixedly installed at the lower side wall of the transparent outer panel 2. The exhaust pipe 503 is connected to the inner cavity of the frame 1 and is used to connect the sealed cavity inside the frame 1 with the external environment, serving as a channel for air outlet.

[0043] An exhaust fan 504 is also fixedly installed inside the exhaust duct 503 to provide power for forced airflow and drive the internal hot air to be discharged. A check valve is also installed on the exhaust duct 503 to prevent external airflow from flowing back into the inner cavity of the frame 1 through the exhaust duct 503, ensuring unidirectional flow of internal airflow driven by the fan, thereby maintaining the sealing reliability under normal conditions.

[0044] Furthermore, in order to form interconnected internal air ducts between the various grid spaces separated by the intersection of metal horizontal plates 401 and metal vertical plates 402, such as Figure 4 and Figure 5 As shown, several metal horizontal plates 401 are provided with elongated holes 505, forming channels that allow air to flow between adjacent vertical air ducts separated by metal vertical plates 402.

[0045] With this technical solution, when the exhaust fan 504 is started and heat dissipation needs to be enhanced, the internal air can be driven from the exhaust port 501 into the sealed cavity of the frame 1, and then evenly pass through the three-dimensional grid of the metal shielding mesh 4. Through the elongated holes 505 on the metal horizontal plate 401, the cooling air can flow between different vertical air ducts and exchange heat with the metal horizontal plate 401 and the metal vertical plate 402. The airflow after heat exchange is discharged from the exhaust pipe 503 under the drive of the fan, thereby improving the overall heat dissipation efficiency.

[0046] In a preferred embodiment of this application, in order to further improve the direct cooling efficiency of specific high-power heat-generating components inside the cabinet, such as... Figure 3 and Figure 6 As shown, a heat-conducting seat 6 is fixedly connected to the side wall of the transparent inner panel 3, and several heat-conducting connecting plates 601 are provided on the side wall of the heat-conducting seat 6.

[0047] Several heat-conducting connecting plates 601 all pass through the pre-set sealed mounting holes on the transparent inner panel 3 and are fixedly connected to the metal shielding mesh 4 by welding, forming a heat conduction path.

[0048] Through this technical solution, the main heat-generating power devices inside the cabinet can be directly installed and fixed on the heat-conducting seat 6 located inside the cabinet by setting the heat-conducting seat 6, which plays the role of directly conducting the heat of the device to the heat-conducting seat 6. At the same time, the metal shielding mesh 4 of this application not only has the function of shielding electromagnetic interference, but also has the function of auxiliary heat conduction and heat dissipation as an extended heat dissipation surface. The overall technical solution formed by the ventilation module 5 can quickly transfer the heat generated by the heat-generating device to the entire metal shielding mesh 4 through the heat-conducting seat 6 and the heat-conducting connecting plate 601, and then be carried away by the forced airflow, which achieves the targeted heat dissipation effect of the core heat source.

[0049] As a preferred technical solution, in order to ensure good electromagnetic shielding and thermal conductivity, both the metal shielding mesh 4 and the heat conduction base 6 are made of aluminum alloy or copper alloy with excellent electrical and thermal conductivity. By selecting such metal materials, the electromagnetic shielding effectiveness and thermal conductivity can be ensured.

[0050] In one preferred embodiment of the metal shielding mesh 4, see [reference]. Figure 7 and Figure 8 As shown, the metal shielding mesh 4 is composed of a first shielding mesh 4011 and a second shielding mesh 4012; it is used to achieve adjustable mesh opening, thereby dynamically balancing electromagnetic shielding effectiveness and ventilation and heat dissipation requirements.

[0051] Adjusting rods 4013 are fixedly connected to both the top and bottom sides of the first shielding net 4011, and adjusting rods 4013 are fixedly connected to both the left and right sides of the second shielding net 4012.

[0052] The adjusting rods 4013 connecting the first shielding net 4011 and the second shielding net 4012 both pass through the corresponding guide grooves on the side wall of the frame 1 and slide with the frame 1, forming two independent adjusting structures that can slide in mutually perpendicular directions, used to control the positions of the first shielding net 4011 and the second shielding net 4012 respectively.

[0053] The adjusting rod 4013 is threaded with a locking bolt 4014, which is used to lock the adjusting rod 4013 to the frame 1 after it is adjusted to the desired position to prevent slippage.

[0054] With the above technical solution, when the working environment of the equipment changes, it can be adjusted according to actual needs. During the adjustment operation, first loosen the locking bolt 4014 on the corresponding adjustment rod 4013, then move the adjustment rod 4013 to adjust the relative position of the first shielding mesh 4011 and the second shielding mesh 4012, thereby making the mesh holes of the two shielding meshes staggered and adjusting the electromagnetic wave leakage aperture of the entire structure. At the same time, due to the setting of the transparent outer panel 2 and the transparent inner panel 3, the alignment status of the two metal shielding meshes and the equipment status inside the cabinet can be observed directly and in real time from the outside during the adjustment process, which is convenient for observing the adjustment effect and equipment status.

[0055] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
