[0022] This application proposes an electronic communication cabinet, see Figure 1 、 2, 3, 5, the electronic communication cabinet includes a cabinet body 1, multiple equipment placement panels 2, a first air guide box body 3 and a first fan 4. The opposite side walls of the cabinet body 1 are provided with multiple groups of corresponding first air inlets 11 and first air outlets 12, and a first air duct is formed between the corresponding first air inlet 11 and first air outlet 12. Multiple equipment placement panels 2 are arranged at intervals in the cabinet body 1. The equipment placement panels 2 are used to place various types of hardware. The first air duct is adjacent to the bottom of the equipment placement panel 2. The first air guide box body 3 is arranged on the side of the cabinet body 1. The first air guide box body 3 is provided with a first air guide cavity 32. The first air guide box body 3 is provided with multiple first air guide ports 31. The first air guide ports 31 are connected to the first air inlet 11. The first fan 4 is connected to the first air guide box body 3. Among them, the first fan 4 blows flowing air into the first air guide box body 3. The air passes through the first air guide cavity 32 and enters the first air duct via the first air inlet 11 to take away the heat from the bottom of the equipment placement panel 2.

[0023] Specifically, the cabinet body 1 can be made of metal materials, such as aluminum alloy or stainless steel, to provide sufficient structural strength and heat dissipation performance. The equipment placement plate 2 can be horizontally arranged in the cabinet body 1, and the specific number can be adjusted according to actual needs. The first air guide box 3 can be welded or bolted to the side of the cabinet body 1, and the shape of the first air guide cavity 32 can be rectangular, trapezoidal or other shapes suitable for air guide. The number and size of the first air guide ports 31 can be designed according to the heat dissipation requirements, such as adopting a uniform distribution or gradient distribution arrangement. The first fan 4 can select an axial flow fan or a centrifugal fan, and its power and air volume should match the heat dissipation requirements.

[0024] There are many ways to realize the formation of the first air duct. For example, the first air inlet 11 and the first air outlet 12 can be directly formed by opening a through hole in the side wall of the cabinet 1, or the air duct can be constructed by adding an air guide plate or an air guide duct. The relative position relationship between the equipment placement plate 2 and the first air duct can be adjusted, for example, the first air duct can be set directly below or diagonally below the equipment placement plate 2. The installation position of the first air guide box 3 can be optimized according to the structure of the cabinet 1, for example, it can be installed on one side or both sides of the cabinet 1. The connection method of the first air guide port 31 can be achieved by direct docking or by connecting through a hose.

[0025] Therefore, this technical solution, by providing a special first air duct and air guide system, can accurately guide the cooling air to the key heat dissipation area at the bottom of the equipment placement plate 2. Compared with the solution of setting a decentralized fan at the bottom of the cabinet in the prior art, this solution significantly improves the heat dissipation efficiency by constructing a directional air duct, so that the airflow is concentrated on the main heat-generating area where the equipment is connected to the frame. At the same time, the structural design of the air guide box can effectively control the direction and speed of the airflow, avoiding energy waste caused by wind dispersion. This solution is particularly suitable for communication equipment that needs to operate stably for a long time, and can effectively solve the problem of local overheating at the bottom of the equipment.

[0026] Further, see Figure 6 The present application also proposes that in the electronic communication cabinet, a sealing plate 21 is provided below the equipment placement plate 2, and the sealing plate 21 is spaced apart from the equipment placement plate 2 to form a first air duct.

[0027] Specifically, the sealing plate 21 can be made of metal sheet or engineering plastic and fixed to the support frames on both sides of the cabinet 1 by bolts or clips. The spacing between the sealing plate 21 and the equipment placement plate 2 is preferably 5 to 10 cm, and this spacing can be adjusted according to actual heat dissipation requirements. A rubber sealing strip can be provided on the edge of the sealing plate 21 to ensure sealing with the side wall of the cabinet 1. As a preferred embodiment, the sealing plate 21 can be designed as a detachable structure to facilitate subsequent maintenance and cleaning.

[0028] Thus, by providing a closed air duct with the sealing plate 21 and the equipment placement plate 2, airflow is prevented from flowing to other areas, effectively directing airflow through the bottom area of ​​the equipment placement plate 2, significantly improving heat transfer efficiency to the equipment installation area. Compared with the open bottom heat dissipation structure in the prior art, this design allows the cooling airflow to be more concentrated on the bottom contact surface of the equipment, where heat is most severe, solving the technical problem of wind dispersion in traditional heat dissipation methods. At the same time, the sealed structure prevents air leakage, ensuring maximum heat dissipation efficiency.

[0029] Furthermore, the present application also proposes that the equipment placement plate 2 in the electronic communication cabinet is made of a heat-conductive material, and a plurality of heat dissipation holes are provided on the surface of the equipment placement plate 2 .

[0030] Specifically, the heat-conducting material can be aluminum alloy, copper alloy or other metal materials with good thermal conductivity to ensure that the device placement plate 2 can effectively conduct the heat generated by the hardware device. The heat dissipation holes can be circular, square or other shapes, evenly distributed on the surface of the device placement plate 2 to increase the heat dissipation area and promote air circulation. As a preferred embodiment, the diameter or side length of the heat dissipation holes can be adjusted according to actual heat dissipation requirements, such as using circular through holes with a diameter of 5mm to 10mm, or square through holes with a side length of 5mm to 8mm. In addition, the arrangement of the heat dissipation holes can be array-type or staggered to optimize the heat dissipation effect.

[0031] Therefore, this technical solution, through the design of the device placement plate 2 made of thermally conductive material and heat dissipation holes, can more efficiently transfer the heat generated by the hardware equipment to the surrounding air, and remove the heat through air flow. Compared with the traditional cabinet method of relying solely on the bottom fan to dissipate heat, this solution can directly dissipate heat in the contact area between the equipment and the placement plate, reducing heat accumulation and improving heat dissipation efficiency. At the same time, the design of the heat dissipation holes further enhances air circulation, allowing heat to be dissipated more quickly, thereby reducing the operating temperature of the hardware equipment and improving the stability of equipment operation.

[0032] Further, see Figure 1 、 2 , 4, 5, the present application also proposes that a plurality of corresponding second air inlets 13 and second air outlets 14 are provided on the opposite side walls of the cabinet 1, and a second air duct is formed between the corresponding second air inlet 13 and second air outlet 14, and the second air duct is located between the hardware equipment and the sealing plate 21. The electronic communication cabinet also includes a second air duct box 5 and a second fan 6. The second air duct box 5 is provided on the side of the cabinet 1, and the second air duct box 5 is arranged opposite to the first air duct box 3. The second air duct box 5 is provided with a second air duct cavity 52, and the second air duct box 5 is provided with a plurality of second air ducts 51, and the second air ducts 51 are connected to the second air inlet 13. The second fan 6 is connected to the second air duct box 5. Among them, the second fan 6 blows flowing air into the second air duct box 5, and the air passes through the second air duct cavity 52 and enters the second air duct via the second air inlet 13 to take away the heat emitted from above the hardware equipment.

[0033] This technical solution achieves targeted cooling of the area above the hardware equipment by adding a second air duct and a second air guide system. The second air duct, located directly above the hardware equipment, directly removes the rising heat generated by the equipment during operation. The coordinated operation of these two ducts significantly improves heat dissipation efficiency, resolving the issue of uneven heat dissipation in densely populated areas within communications cabinets. This design is particularly suitable for heat-generating communications equipment such as switches and servers, effectively reducing operating temperatures and improving operational stability.

[0034] Further, see Figure 2 、 3 , 4, 5, the present application also proposes that the first air guide box body 3 is provided with a first opening 33 running through both sides, the first opening 33 is connected to the second air outlet 14, and the second air guide box body 5 is provided with a second opening 53 running through both sides, the second opening 53 is connected to the first air outlet 12; wherein, the hot air passing through the first air outlet 12 is discharged via the second opening 53, and the hot air passing through the second air outlet 14 is discharged via the first opening 33.

[0035] Specifically, the first opening 33 and the second opening 53 can adopt a circular, square, or other shaped through-hole structure, and the size of the opening can be adjusted according to the actual air volume required. As a preferred embodiment, the first opening 33 and the second opening 53 can be provided with a guide structure, such as a guide plate or a guide groove, to optimize the airflow direction. Furthermore, a sealing strip can be provided on the edge of the opening to reduce air leakage. In addition, the position of the opening can be flexibly arranged according to the internal structure of the cabinet, for example, it can be arranged at the top, middle, or bottom of the air guide box.

[0036] Therefore, this technical solution realizes the cross exhaust of hot air flow by setting up interconnected opening structures. The specific working principle is: after the hot air flow in the first air duct is discharged from the first air outlet 12, it is led out through the second opening 53 of the second air guide box 5; at the same time, after the hot air flow in the second air duct is discharged from the second air outlet 14, it is led out through the first opening 33 of the first air guide box 3. This cross exhaust method can make the air flow have a clear flow direction, effectively avoid the formation of vortexes in the hot air flow inside the cabinet, and improve the heat dissipation efficiency. At the same time, it ensures that under the premise of setting air guide boxes on both sides, they will not affect the air outlet position. Compared with the existing technology, this solution can more effectively organize the airflow path, so that the hot air is quickly discharged from the cabinet, thereby improving the overall heat dissipation effect inside the cabinet.

[0037] Further, see Figure 3 、 4 , the present application also proposes that the cross-sectional area of ​​the first air guide cavity 32 gradually decreases from top to bottom; the cross-sectional area of ​​the second air guide cavity 52 gradually decreases from top to bottom.

[0038] Specifically, the change in the cross-sectional area of ​​the first air guide cavity 32 and the second air guide cavity 52 can be achieved in the following manner: the side walls of the air guide box body are designed to be inclined so that the internal space of the cavity gradually shrinks from top to bottom. As a preferred embodiment, the two side walls of the air guide box body can be symmetrically inclined to form an air guide cavity with a trapezoidal cross-section. Furthermore, the change in the cross-sectional area of ​​the air guide cavity can also be achieved in a step-by-step manner, that is, it is formed by connecting multiple cavity segments of different diameters. In addition, the change in the cross-sectional area of ​​the air guide cavity can also be achieved by a curved surface transition, so that the airflow flows more smoothly.

[0039] Because the fan is connected to the top of the air guide box, and the multiple air inlets are at different distances from the top air inlet of the air guide box, the air flow rate is faster at the air inlets near the top of the air guide box, while the air flow rate is slower at the air inlets farther away from the top of the air guide box, resulting in uneven air volume distribution. Therefore, the air guide cavity is designed with a structure with a gradually decreasing cross-sectional area. This can reduce the air flow rate near the top air inlet and increase the air flow rate farther away from the top air inlet. By complementing each other, the air flow rate of the air inlets at various locations is ensured to be consistent as much as possible.

[0040] Further, see Figure 3 、 4 The present application also proposes that the sizes of the plurality of first air guide vents 31 gradually increase from top to bottom, and the sizes of the plurality of second air guide vents 51 gradually increase from top to bottom.

[0041] Specifically, the first air guide 31 and the second air guide 51 adopt a gradual design, with the upper air guide opening being smaller and the lower air guide opening being larger. As a preferred embodiment, the air guide can be rectangular or circular, with the opening area increasing linearly or nonlinearly. Furthermore, the air guide can adopt an adjustable louver structure, with the opening size controlled by a mechanical device.

[0042] Therefore, this technical solution achieves precise control of air volume distribution by optimizing the size distribution of air guide ports. Since the fan is connected to the top of the air guide box, and the distances of multiple air inlets from the top air inlet of the air guide box are inconsistent, the air flow rate of the air inlet close to the top of the air guide box is faster, and the air flow rate of the air inlet far from the top of the air guide box is slower, resulting in uneven air volume distribution. The gradient air guide port design allows more airflow to be directed to the lower area, effectively solving the problem of uneven air volume distribution caused by traditional uniform-sized air guide ports. Compared with the existing technology, this solution can provide a more reasonable air volume distribution under the same fan power, significantly improving the heat dissipation efficiency. Specifically, the upper area avoids overcooling, the lower high-temperature area obtains sufficient heat dissipation, and the overall temperature distribution is more balanced.

[0043] The first air inlet 11 and the second air inlet 13 are both provided with dustproof nets.

[0044] Further, see Figure 2 、 5 6. The present application also proposes that the electronic communication cabinet includes a plurality of opening and closing components 7. The opening and closing components 7 are used to open the first air inlet 11 to ensure heat dissipation when hardware equipment is placed on the equipment placement plate 2, and to block the first air inlet 11 when no hardware equipment is placed on the equipment placement plate 2 to increase the air intake of other first air inlets 11.

[0045] The opening and closing assembly 7 includes a shielding member 71, a push plate 72 and a magnetic member 73. The shielding member 71 blocks the first air inlet 11. The push plate 72 is connected to the shielding member 71, and the push plate 72 is protrudingly arranged on the upper part of the device placement plate 2, and the push plate 72 is slidable back and forth. The magnetic member 73 is located on one side of the push plate 72 and is magnetically connected to the push plate 72. When the hardware device is placed on the device placement plate 2, the push plate 72 is pushed to move inward, the push plate 72 is disconnected from the magnetic member 73, and the push plate 72 drives the shielding member 71 to move. The opening of the shielding member 71 is misaligned with the opening of the first air inlet 11 to open the first air inlet 11. When the hardware device is taken out, the magnetic member 73 magnetically attracts the push plate 72 back to its original position, and the shielding member 71 is reset to complete the shielding.

[0046] Specifically, the shielding member 71 can be made of a metal plate or a plastic plate, and its shape matches the first air inlet 11 to ensure complete shielding. The push plate 72 can be made of lightweight metal or high-strength plastic, and the height of its protruding part can be adjusted according to the thickness of the hardware device. The magnetic attraction member 73 can be made of a permanent magnet or an electromagnet, and the magnetic force can be adjusted as needed to ensure that the push plate 72 can be stably adsorbed or released. As a preferred embodiment, the push plate 72 and the shielding member 71 can be connected by a connecting rod or a slide rail to achieve synchronous movement.

[0047] Therefore, this technical solution realizes the automatic opening and closing of the first air inlet 11 through the setting of the opening and closing component 7. When the hardware device is placed on the device placement plate 2, the push plate 72 is pushed, driving the shielding member 71 to move, thereby opening the first air inlet 11 and ensuring that the heat dissipation air duct is unobstructed. When the hardware device is taken out, the magnetic member 73 adsorbs the push plate 72 back to its original position, and the shielding member 71 is reset, closing the first air inlet 11 to avoid waste of cold air, while increasing the air intake of other first air inlets 11, concentrating wind power to efficiently dissipate heat for equipment that needs heat dissipation. This solution solves the problem of dispersed wind power and inability to accurately dissipate heat in the existing technology of the cooling fan, improves heat dissipation efficiency, and reduces energy consumption. This solution can accurately allocate air volume according to the actual distribution of equipment, and solves the problem of ineffective heat dissipation caused by the lack of equipment in some areas.

[0048] This technical solution achieves intelligent control of the first air inlet 11 through the setting of the opening and closing component 7. When a hardware device is placed on the device placement plate 2, the opening and closing component 7 automatically opens the corresponding first air inlet 11 to ensure the heat dissipation effect; when no hardware device is placed on the device placement plate 2, the opening and closing component 7 automatically closes the corresponding first air inlet 11, concentrating the air volume to other locations that need heat dissipation. This design effectively solves the problems of wind dispersion and low heat dissipation efficiency in the existing technology, and improves the accuracy and energy efficiency of the heat dissipation system. Compared with the existing technology, this solution does not require the additional setting of sensors or control circuits, has a simple and reliable structure, and has low maintenance costs.

[0049] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
